President Obama plans to announce legislation Tuesday that would shield companies from lawsuits for sharing computer threat data with the government in an effort to prevent cyber­attacks. On the heels of a destructive attack at Sony Pictures Entertainment and major breaches at JPMorgan Chase and retail chains, Obama is intent on capitalizing on the heightened sense of urgency to improve the security of the nation’s networks, officials said. “He’s been doing everything he can within his executive authority to move the ball on this,” said a senior administration official who spoke on the condition of anonymity to discuss legislation that has not yet been released. “We’ve got to get something in place that allows both industry and government to work more closely together.”

The legislation is part of a broader package, to be sent to Capitol Hill on Tuesday, that includes measures to help protect consumers and students against ­cyberattacks and to give law enforcement greater authority to combat cybercrime. The provision’s goal is to “enshrine in law liability protection for the private sector for them to share specific information — cyberthreat indicators — with the government,” the official said. Some analysts questioned the need for such legislation, saying there are adequate measures in place to enable sharing between companies and the government and among companies.

“We think the current information-sharing regime is adequate,” said Mark Jaycox, legislative analyst at the Electronic Frontier Foundation, a privacy group. “More companies need to use it, but the idea of broad legal immunity isn’t needed right now.” The administration official disagreed. The lack of such immunity is what prevents many companies from greater sharing of data with the government, the official said. “We have heard that time and time again,” the official said. The proposal, which builds on a 2011 administration bill, grants liability protection to companies that provide indicators of cyberattacks and threats to the Department of Homeland Security.

Less than a week after the attacks in Paris — while the public and policymakers were still reeling, and the investigation had barely gotten off the ground — Cy Vance, Manhattan’s District Attorney, released a policy paper calling for legislation requiring companies to provide the government with backdoor access to their smartphones and other mobile devices. This is the first concrete proposal of this type since September 2014, when FBI Director James Comey reignited the “Crypto Wars” in response to Apple’s and Google’s decisions to use default encryption on their smartphones. Though Comey seized on Apple’s and Google’s decisions to encrypt their devices by default, his concerns are primarily related to end-to-end encryption, which protects communications that are in transit. Vance’s proposal, on the other hand, is only concerned with device encryption, which protects data stored on phones. It is still unclear whether encryption played any role in the Paris attacks, though we do know that the attackers were using unencrypted SMS text messages on the night of the attack, and that some of them were even known to intelligence agencies and had previously been under surveillance. But regardless of whether encryption was used at some point during the planning of the attacks, as I lay out below, prohibiting companies from selling encrypted devices would not prevent criminals or terrorists from being able to access unbreakable encryption. Vance’s primary complaint is that Apple’s and Google’s decisions to provide their customers with more secure devices through encryption interferes with criminal investigations. He claims encryption prevents law enforcement from accessing stored data like iMessages, photos and videos, Internet search histories, and third party app data. He makes several arguments to justify his proposal to build backdoors into encrypted smartphones, but none of them hold water.

Before addressing the major privacy, security, and implementation concerns that his proposal raises, it is worth noting that while an increase in use of fully encrypted devices could interfere with some law enforcement investigations, it will help prevent far more crimes — especially smartphone theft, and the consequent potential for identity theft. According to Consumer Reports, in 2014 there were more than two million victims of smartphone theft, and nearly two-thirds of all smartphone users either took no steps to secure their phones or their data or failed to implement passcode access for their phones. Default encryption could reduce instances of theft because perpetrators would no longer be able to break into the phone to steal the data.

Vance argues that creating a weakness in encryption to allow law enforcement to access data stored on devices does not raise serious concerns for security and privacy, since in order to exploit the vulnerability one would need access to the actual device. He considers this an acceptable risk, claiming it would not be the same as creating a widespread vulnerability in encryption protecting communications in transit (like emails), and that it would be cheap and easy for companies to implement. But Vance seems to be underestimating the risks involved with his plan. It is increasingly important that smartphones and other devices are protected by the strongest encryption possible. Our devices and the apps on them contain astonishing amounts of personal information, so much that an unprecedented level of harm could be caused if a smartphone or device with an exploitable vulnerability is stolen, not least in the forms of identity fraud and credit card theft. We bank on our phones, and have access to credit card payments with services like Apple Pay. Our contact lists are stored on our phones, including phone numbers, emails, social media accounts, and addresses. Passwords are often stored on people’s phones. And phones and apps are often full of personal details about their lives, from food diaries to logs of favorite places to personal photographs. Symantec conducted a study, where the company spread 50 “lost” phones in public to see what people who picked up the phones would do with them. The company found that 95 percent of those people tried to access the phone, and while nearly 90 percent tried to access private information stored on the phone or in other private accounts such as banking services and email, only 50 percent attempted contacting the owner.

The European Parliament narrowly adopted a nonbinding but nonetheless forceful resolution on Thursday urging the 28 nations of the European Union to recognize Edward J. Snowden as a “whistle-blower and international human rights defender” and shield him from prosecution.On Twitter, Mr. Snowden, the former National Security Agency contractor who leaked millions of documents about electronic surveillance by the United States government, called the vote a “game-changer.” But the resolution has no legal force and limited practical effect for Mr. Snowden, who is living in Russia on a three-year residency permit.Whether to grant Mr. Snowden asylum remains a decision for the individual European governments, and none have done so thus far. Continue reading the main story Related Coverage Open Source: Now Following the N.S.A. on Twitter, @SnowdenSEPT. 29, 2015 Snowden Sees Some Victories, From a DistanceMAY 19, 2015 Still, the resolution was the strongest statement of support seen for Mr. Snowden from the European Parliament. At the same time, the close vote — 285 to 281 — suggested the extent to which some European lawmakers are wary of alienating the United States.

The resolution calls on European Union members to “drop any criminal charges against Edward Snowden, grant him protection and consequently prevent extradition or rendition by third parties.”In June 2013, shortly after Mr. Snowden’s leaks became public, the United States charged him with theft of government property and violations of the Espionage Act of 1917. By then, he had flown to Moscow, where he spent weeks in legal limbo before he was granted temporary asylum and, later, a residency permit.Four Latin American nations have offered him permanent asylum, but he does not believe he could travel from Russia to those countries without running the risk of arrest and extradition to the United States along the way.

The White House, which has used diplomatic efforts to discourage even symbolic resolutions of support for Mr. Snowden, immediately criticized the resolution.“Our position has not changed,” said Ned Price, a spokesman for the National Security Council in Washington.“Mr. Snowden is accused of leaking classified information and faces felony charges here in the United States. As such, he should be returned to the U.S. as soon as possible, where he will be accorded full due process.”Jan Philipp Albrecht, one of the lawmakers who sponsored the resolution in Europe, said it should increase pressure on national governments.

Today we are releasing the implementation guide for EFF’s Do Not Track (DNT) policy. For years users have been able to set a Do Not Track signal in their browser, but there has been little guidance for websites as to how to honor that request. EFF’s DNT policy sets out a meaningful response for servers to follow, and this guide provides details about how to apply it in practice. At its core, DNT protects user privacy by excluding the use of unique identifiers for cross-site tracking, and by limiting the retention period of log data to ten days. This short retention period gives sites the time they need for debugging and security purposes, and to generate aggregate statistical data. From this baseline, the policy then allows exceptions when the user's interactions with the site—e.g., to post comments, make a purchase, or click on an ad—necessitates collecting more information. The site is then free to retain any data necessary to complete the transaction. We believe this approach balances users’ privacy expectations with the ability of websites to deliver the functionality users want. Websites often integrate third-party content and rely on third-party services (like content delivery networks or analytics), and this creates the potential for user data to be leaked despite the best intentions of the site operator. The guide identifies potential pitfalls and catalogs providers of compliant services. It is common, for example, to embed media from platforms like You Tube, Sound Cloud, and Twitter, all of which track users whenever their widgets are loaded. Fortunately, Embedly, which offers control over the appearance of embeds, also supports DNT via its API, displaying a poster instead and loading the widget only if the user clicks on it knowingly.

Knowledge makes the difference between willing tracking and non-consensual tracking. Users should be able to choose whether they want to give up their privacy in exchange for using a site or a  particular feature. This means sites need to be transparent about their practices. A great example of this is our biggest adopter, Medium, which does not track DNT users who browse the site and gives clear information about tracking to users when they choose to log in. This is their previous log-in panel, the DNT language is currently being added to their new interface.

National plaintiffs’ law firm Keller Lenkner LLC and global business litigation firm Quinn Emanuel Urquhart & Sullivan, LLP filed a class-action lawsuit against Facebook, Inc. alleging violations of federal antitrust laws and California law on behalf of Facebook users.ADVERTISEMENTFiled in the U.S. District Court for the Northern District of California, the complaint alleges that Facebook obtained and maintained a social network and social media monopoly by consistently deceiving consumers about the data-privacy protections it provided to users, and by exploiting the data it extracted from users to target smaller startup companies for destruction or acquisition.The lawsuit seeks to put an end to Facebook’s misrepresentations about its privacy practices and its anticompetitive acquisition conduct; to require Facebook to engage in third-party auditing of its conduct; and to require Facebook to divest assets, such as Instagram and WhatsApp, that entrench its market power.

According to the complaint, which was filed on behalf of named plaintiffs Sarah Grabert and Maximilian Klein, Facebook did not achieve its Big Tech monopoly through innovation or vigorous competition. Despite its public pledge to protect user privacy, Facebook lied to users and violated their trust in a scheme to build a technology empire. Facebook also acquired technology from smaller firms that it used to track consumer activity across the internet so that it could identify and target competitors.ADVERTISEMENTThe complaint further alleges that in a strategic, intentional ploy for market domination, Facebook engaged in its scheme to destroy all competition without a care for the ultimate harm it would inflict on consumers. By the time Facebook’s deception about its lackluster privacy protections became public knowledge, Facebook had already achieved dominance, making it difficult for any firm to challenge its social media and social network monopoly.

The complaint notes that Facebook derives enormous economic value from the data it harvests from consumers on its platform. In fact, Facebook itself has described how it generates massive earnings per user from the data it collects. The complaint details how Facebook’s destruction of competition has caused consumers substantial economic injury. Consumers who sign up for Facebook agree to give up their valuable data and attention in exchange for using Facebook’s platform. That information and attention is then sold in measurable units to advertisers in exchange for money. The complaint alleges that consumers were harmed by Facebook’s anticompetitive conduct, as they did not receive the benefit of their bargain with Facebook.The lawsuit includes claims for violations of federal antitrust laws and California common law. It also seeks an order enjoining Facebook from continuing to engage in the alleged wrongful acts, requiring Facebook to engage third-party auditors to evaluate and correct problems with Facebook’s conduct, and requiring Facebook to divest assets like Instagram and WhatsApp. The lawsuit also seeks monetary damages, restitution and/or disgorgement of Facebook’s wrongful gains, attorneys’ fees, and costs.

California’s attorney general has gone to court to force Facebook to hand over documents as part of an investigation into the company. Xavier Becerra filed a “petition to enforce investigative subpoena” with the Superior Court of California in San Francisco on Wednesday morning, arguing that Facebook’s response to his subpoenas has been “patently inadequate.” Citing a “lack of cooperation” not just with his office but also the Federal Trade Commission (FTC), Xavier Becerra points out [PDF] that it took Facebook a year to respond to his initial inquiry to produce documents relating to the Cambridge Analytica scandal, where Facebook allowed a third party to access vast amounts of personal information through its systems.

Not only that but Facebook flat out refused to “search communications involving senior executives,” meaning that it refused to search for relevant information in the emails and other communications of CEO Mark Zuckerberg and COO Sheryl Sandberg, among others. “Facebook is not just continuing to drag its feet, it is failing to comply with lawfully issued subpoenas and interrogatories,” the filing states.

The filing comes the same day that 7,000 pages of internal Facebook files were published online. Those documents were obtained and leaked amid a lawsuit between Facebook and a third-party app developer and were labelled as “highly confidential” by the antisocial network. The main upshot of those files is that they show Facebook used the data it gathered on millions of its users as a business weapon: it provided people's profile information to companies that, for instance, agreed to spend hundreds of thousands of dollars on adverts within Facebook, and it cut off developers that posed a competitive threat to its ever-growing stable of companies and services (or developers that wouldn't pay up, or were just too sketchy for the internet giant.) This confirms earlier reporting. CEO Zuckerberg also continues to avoid visiting London, or anywhere in the UK, out of fear he will be arrested for repeatedly failing to comply with a request by Parliament to answer questions about Facebook’s actions, as revealed in the tranche of documents.

Six4Three recently published a playbook for the FTC to get to the bottom of Facebook’s secretive deals selling user data without privacy controls. In light of The New York Times article reporting multiple criminal investigations into Facebook surrounding these secretive deals, we’re publishing the playbook for criminal investigators.Perhaps the most important recognition at the outset is that the secretive deals that have been reported, whether those with a handful of device manufacturers or with 150 large technology companies, are just the tip of the iceberg. Those secretive deals handing over user data in exchange for gobs of cash were merely part and parcel of a much broader illegal scheme that begins with Facebook’s transition to mobile in 2012 and continues to this very day. We believe this illegal scheme amounts to a clear RICO violation. The United Kingdom Parliament agrees. Here’s how criminal investigators can overcome Facebook’s incredibly effective concealment campaign and bring a viable RICO case.Facebook’s pattern of racketeering activity is a play in three acts from at least 2012 to present. The first act is all about the desperation resulting from the collapse of Facebook’s desktop advertising business right around its IPO and the various securities violations that resulted. The second act is about covering up those securities violations by illegally building its mobile advertising business via extortion and wire fraud in order to close the gap in Facebook’s revenue projections before the world took notice, which likely resulted in additional securities violations. The third act is about covering up the extortion and wire fraud by lying to government officials investigating Facebook while continuing to effectuate the scheme. We are still in the third act.For almost a decade now Facebook has been covering up one illegal act with another in order to hide how it managed to ramp up its mobile advertising business faster than any other business in the history of capitalism. The abuses of Facebook’s data, from Russian interference in the 2016 election to Cambridge Analytica and Brexit, all stem in substantial part from the decisions Facebook knowingly, willfully and maliciously made to facilitate this criminal conspiracy. Put simply, Facebook’s transition to mobile destabilized the world.

That’s not a bug. It’s a function of Apple policy. With some exceptions, the company doesn’t let users pay app makers directly for their apps or digital services. They can only pay Apple, which takes a 30% cut of all revenue and then passes 70% to the developer. (For subscription services, which account for the majority of App Store revenues, that 30% cut drops to 15% after the first year.) To tighten its grip, Apple prohibits the affected apps from even telling users how they can pay their creators directly.In 2018, unwilling to continue paying the “Apple tax,” Netflix followed Spotify and Amazon’s Kindle books app in pulling in-app purchases from its iOS app. Users must now sign up elsewhere, such as on the company’s website, in order for the app to become usable. Of course, these brands are big enough to expect that many users will seek them out anyway.

Smaller app developers, meanwhile, have little choice but to play by Apple’s rules. That’s true even when they’re competing with Apple’s own apps, which pay no such fees and often enjoy deeper access to users’ devices and information.Now, a handful of developers are speaking out about it — and government regulators are beginning to listen. David Heinemeier Hansson, the co-founder of the project management software company Basecamp, told members of the U.S. House antitrust subcommittee in January that navigating the App Store’s fees, rules, and review processes can feel like a “Kafka-esque nightmare.”One of the world’s most beloved companies, Apple has long enjoyed a reputation for user-friendly products, and it has cultivated an image as a high-minded protector of users’ privacy. The App Store, launched in 2008, stands as one of its most underrated inventions; it has powered the success of the iPhone—perhaps the most profitable product in human history. The concept was that Apple and developers could share in one another’s success with the iPhone user as the ultimate beneficiary.

But critics say that gauzy success tale belies the reality of a company that now wields its enormous market power to bully, extort, and sometimes even destroy rivals and business partners alike. The iOS App Store, in their telling, is a case study in anti-competitive corporate behavior. And they’re fighting to change that — by breaking its choke hold on the Apple ecosystem.

The European Union and the U.K. opened formal antitrust investigations into Facebook Inc.’s FB -0.86% classified-ads service Marketplace, ramping up regulatory scrutiny for the company in Europe. Both the European Commission—the EU’s top antitrust enforcer—and the U.K.’s Competition and Markets Authority said Friday they are investigating whether Facebook repurposes data it gathers from advertisers who buy ads in order to give illegal advantages to its own services, including its Marketplace online flea market. The U.K. added that it is also investigating whether Facebook uses advertiser data to give similar advantages to its online-dating service. The two competition watchdogs said they would coordinate their investigations.

Separately on Friday, Germany’s competition regulator announced that it is opening an investigation into Google’s News Showcase, in which the tech company pays to license certain content from news publishers. That probe, which is based on new powers Germany had granted the regulator, will look among other things at whether Google is imposing unfair conditions on publishers and how it selects participants, the Federal Cartel Office said.

The three newly opened cases are part of a new wave of antitrust enforcement in Europe. The European Commission filed formal charges last month against Apple Inc. for allegedly abusing its control over the distribution of music-streaming apps, including Spotify Technology SA . In November, it filed formal charges against Amazon.com Inc. for allegedly using nonpublic data it gathers from third-party sellers to unfairly compete against them. Both companies denied wrongdoing. At the same time, the U.K.’s CMA has opened investigations into Google’s announcement that it will retire third-party cookies, a technology advertisers use to track web users, and whether Apple imposes anticompetitive conditions on some app developers, including the use of Apple’s in-app payment system, which is also the subject of a lawsuit in the U.S. In the EU, the European Commission has been investigating Facebook for more than a year on multiple fronts. Facebook and the Commission have squabbled over access to internal documents as part of those investigations.

The most powerful company on the Internet just got a whole lot creepier: a new service from Google merges offline consumer info with online intelligence, allowing advertisers to target users based on what they do at the keyboard and at the mall. Without much fanfare, Google announced news this week of a new advertising project, Conversions API, that will let businesses build all-encompassing user profiles based off of not just what users search for on the Web, but what they purchase outside of the home. In a blog post this week on Google’s DoubleClick Search site, the Silicon Valley giant says that targeting consumers based off online information only allows advertisers to learn so much. “Conversions,” tech-speak for the digital metric made by every action a user makes online, are incomplete until coupled with real life data, Google says.

Of course, there is always the possibility that all of this information can be unencrypted and, in some cases, obtained by third-parties that you might not want prying into your personal business. Edwards notes in his report that Google does not explicitly note that intelligence used in Conversions API will be anonymized, but the blowback from not doing as much would sure be enough to start a colossal uproar. Meanwhile, however, all of the information being collected by Google — estimated to be on millions of servers around the globe — is being handed over to more than just advertising companies. Last month Google reported that the US government requested personal information from roughly 8,000 individual users during just the first few months of 2012.“This is the sixth time we’ve released this data, and one trend has become clear: Government surveillance is on the rise,” Google admitted with their report.

Pressure on the cellphone industry to introduce technology that could disable stolen smartphones has intensified with the introduction of proposed federal legislation that would mandate such a system.

Pressure on the cellphone industry to introduce technology that could disable stolen smartphones has intensified with the introduction of proposed federal legislation that would mandate such a system.

Senate bill 2032, "The Smartphone Prevention Act," was introduced to the U.S. Senate Wednesday by Amy Klobuchar, a Minnesota Democrat. The bill promises technology that allows consumers to remotely wipe personal data from their smartphones and render them inoperable. But how that will be accomplished is currently unclear. The full text of the bill was not immediately available and the offices of Klobuchar and the bill's co-sponsors were all shut down Thursday due to snow in Washington, D.C.

IBM announced today that it would throw another billion at Linux, the open-source operating system, to run its Power System servers. The first time it had thrown a billion at Linux was in 2001, when Linux was a crazy, untested, even ludicrous proposition for the corporate world. So the moolah back then didn’t go to Linux itself, which was free, but to related technologies across hardware, software, and service, including things like sales and advertising – and into IBM’s partnership with Red Hat which was developing its enterprise operating system, Red Hat Enterprise Linux. “It helped start a flurry of innovation that has never slowed,” said Jim Zemlin, executive director of the Linux Foundation. IBM claims that the investment would “help clients capitalize on big data and cloud computing with modern systems built to handle the new wave of applications coming to the data center in the post-PC era.” Some of the moolah will be plowed into the Power Systems Linux Center in Montpellier, France, which opened today. IBM’s first Power Systems Linux Center opened in Beijing in May. IBM may be trying to make hay of the ongoing revelations that have shown that the NSA and other intelligence organizations in the US and elsewhere have roped in American tech companies of all stripes with huge contracts to perfect a seamless spy network. They even include physical aspects of surveillance, such as license plate scanners and cameras, which are everywhere [read.... Surveillance Society: If You Drive, You Get Tracked].

It would be an enormous competitive advantage for an IBM salesperson to walk into a government or corporate IT department and sell Big Data servers that don’t run on Windows, but on Linux. With the Windows 8 debacle now in public view, IBM salespeople don’t even have to mention it. In the hope of stemming the pernicious revenue decline their employer has been suffering from, they can politely and professionally hype the security benefits of IBM’s systems and mention in passing the comforting fact that some of it would be developed in the Power Systems Linux Centers in Montpellier and Beijing. Alas, Linux too is tarnished. The backdoors are there, though the code can be inspected, unlike Windows code. And then there is Security-Enhanced Linux (SELinux), which was integrated into the Linux kernel in 2003. It provides a mechanism for supporting “access control” (a backdoor) and “security policies.” Who developed SELinux? Um, the NSA – which helpfully discloses some details on its own website (emphasis mine): The results of several previous research projects in this area have yielded a strong, flexible mandatory access control architecture called Flask. A reference implementation of this architecture was first integrated into a security-enhanced Linux® prototype system in order to demonstrate the value of flexible mandatory access controls and how such controls could be added to an operating system. The architecture has been subsequently mainstreamed into Linux and ported to several other systems, including the Solaris™ operating system, the FreeBSD® operating system, and the Darwin kernel, spawning a wide range of related work.

Then another boon for IBM. Experts at the German Federal Office for Security in Information Technology (BIS) determined that Windows 8 is dangerous for data security. It allows Microsoft to control the computer remotely through a “special surveillance chip,” the wonderfully named Trusted Platform Module (TPM), and a backdoor in the software – with keys likely accessible to the NSA and possibly other third parties, such as the Chinese. Risks: “Loss of control over the operating system and the hardware” [read.... LEAKED: German Government Warns Key Entities Not To Use Windows 8 – Links The NSA.

The Federal Communications Commission is poised to ruin the free Internet on a technicality. The group is expected to introduce new net neutrality laws that would allow companies to pay for better access to consumers through deals similar to the one struck by Netflix and Comcast earlier this year. The argument is that those deals don’t technically fall under the net neutrality umbrella, so these new rules won’t apply to them even though they directly affect the Internet. At least the commission is being upfront about its disinterest in protecting the free Internet.

The Verge notes that the proposed rules will offer some protections to consumers: The Federal Communication Commission’s proposal for new net neutrality rules will allow internet service providers to charge companies for preferential treatment, effectively undermining the concept of net neutrality, according to The Wall Street Journal. The rules will reportedly allow providers to charge for preferential treatment so long as they offer that treatment to all interested parties on “commercially reasonable” terms, with the FCC will deciding whether the terms are reasonable on a case-by-case basis. Providers will not be able to block individual websites, however. The goal of net neutrality rules is to prevent service providers from discriminating between different content, allowing all types of data and all companies’ data to be treated equally. While it appears that outright blocking of individual services won’t be allowed, the Journal reports that some forms of discrimination will be allowed, though that will apparently not include slowing down websites.

Re/code summarizes the discontent with these proposed rules: Consumer groups have complained about that plan because they’re worried that Wheeler’s rules may not hold up in court either. A federal appeals court rejected two previous versions of net neutrality rules after finding fault in the FCC’s legal reasoning. During the latest smackdown, however, the court suggested that the FCC had some authority to impose net neutrality rules under a section of the law that gives the agency the ability to regulate the deployment of broadband lines. Internet activists would prefer that the FCC just re-regulate Internet lines under old rules designed for telephone networks, which they say would give the agency clear authority to police Internet lines. Wheeler has rejected that approach for now. Phone and cable companies, including Comcast, AT&T and Verizon, have vociferously fought that idea over the past few years.

WASHINGTON (AP) -- The Obama administration has been quietly advising local police not to disclose details about surveillance technology they are using to sweep up basic cellphone data from entire neighborhoods, The Associated Press has learned. Citing security reasons, the U.S. has intervened in routine state public records cases and criminal trials regarding use of the technology. This has resulted in police departments withholding materials or heavily censoring documents in rare instances when they disclose any about the purchase and use of such powerful surveillance equipment. Federal involvement in local open records proceedings is unusual. It comes at a time when President Barack Obama has said he welcomes a debate on government surveillance and called for more transparency about spying in the wake of disclosures about classified federal surveillance programs.

One well-known type of this surveillance equipment is known as a Stingray, an innovative way for law enforcement to track cellphones used by suspects and gather evidence. The equipment tricks cellphones into identifying some of their owners' account information, like a unique subscriber number, and transmitting data to police as if it were a phone company's tower. That allows police to obtain cellphone information without having to ask for help from service providers, such as Verizon or AT&T, and can locate a phone without the user even making a call or sending a text message. But without more details about how the technology works and under what circumstances it's used, it's unclear whether the technology might violate a person's constitutional rights or whether it's a good investment of taxpayer dollars. Interviews, court records and public-records requests show the Obama administration is asking agencies to withhold common information about the equipment, such as how the technology is used and how to turn it on. That pushback has come in the form of FBI affidavits and consultation in local criminal cases.

"These extreme secrecy efforts are in relation to very controversial, local government surveillance practices using highly invasive technology," said Nathan Freed Wessler, a staff attorney with the American Civil Liberties Union, which has fought for the release of these types of records. "If public participation means anything, people should have the facts about what the government is doing to them." Harris Corp., a key manufacturer of this equipment, built a secrecy element into its authorization agreement with the Federal Communications Commission in 2011. That authorization has an unusual requirement: that local law enforcement "coordinate with the FBI the acquisition and use of the equipment." Companies like Harris need FCC authorization in order to sell wireless equipment that could interfere with radio frequencies. A spokesman from Harris Corp. said the company will not discuss its products for the Defense Department and law enforcement agencies, although public filings showed government sales of communications systems such as the Stingray accounted for nearly one-third of its $5 billion in revenue. "As a government contractor, our solutions are regulated and their use is restricted," spokesman Jim Burke said.
