In a secret meeting convened by the White House around Thanksgiving, senior national security officials ordered agencies across the U.S. government to find ways to counter encryption software and gain access to the most heavily protected user data on the most secure consumer devices, including Apple Inc.’s iPhone, the marquee product of one of America’s most valuable companies, according to two people familiar with the decision.The approach was formalized in a confidential National Security Council “decision memo,” tasking government agencies with developing encryption workarounds, estimating additional budgets and identifying laws that may need to be changed to counter what FBI Director James Comey calls the “going dark” problem: investigators being unable to access the contents of encrypted data stored on mobile devices or traveling across the Internet. Details of the memo reveal that, in private, the government was honing a sharper edge to its relationship with Silicon Valley alongside more public signs of rapprochement.

On Tuesday, the public got its first glimpse of what those efforts may look like when a federal judge ordered Apple to create a special tool for the FBI to bypass security protections on an iPhone 5c belonging to one of the shooters in the Dec. 2 terrorist attack in San Bernardino, California that killed 14 people. Apple Chief Executive Officer Tim Cook has vowed to fight the order, calling it a “chilling” demand that Apple “hack our own users and undermine decades of security advancements that protect our customers.” The order was not a direct outcome of the memo but is in line with the broader government strategy.White House spokesman Josh Earnest said Wednesday that the Federal Bureau of Investigation and Department of Justice have the Obama administration’s “full” support in the matter. The government is “not asking Apple to redesign its product or to create a new backdoor to their products,” but rather are seeking entry “to this one device,” he said.

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.

Imagine if someone could scan every image on Facebook, Twitter, and Instagram, then instantly determine where each was taken. The ability to combine this location data with information about who appears in those photos—and any social media contacts tied to them—would make it possible for government agencies to quickly track terrorist groups posting propaganda photos. (And, really, just about anyone else.) That's precisely the goal of Finder, a research program of the Intelligence Advanced Research Projects Agency (IARPA), the Office of the Director of National Intelligence's dedicated research organization. For many photos taken with smartphones (and with some consumer cameras), geolocation information is saved with the image by default. The location is stored in the Exif (Exchangable Image File Format) data of the photo itself unless geolocation services are turned off. If you have used Apple's iCloud photo store or Google Photos, you've probably created a rich map of your pattern of life through geotagged metadata. However, this location data is pruned off for privacy reasons when images are uploaded to some social media services, and privacy-conscious photographers (particularly those concerned about potential drone strikes) will purposely disable geotagging on their devices and social media accounts.

The encryption debate dates back to Clinton administration proposals for the “clipper chip” and mandatory deposit of decryption keys. But that debate reached new prominence in connection with the FBI’s efforts to compel Apple to decrypt the phone of a dead terrorist in the San Bernardino case. A new study by the National Academies of Sciences, Engineering, and Medicine tries to shed some light, and turn down the heat, in the debate over whether government agencies should be provided access to plaintext versions of encrypted communications and other data. FBI and other law enforcement officials, and some intelligence officials, have argued that in the face of widespread encryption provided by smart phones, messaging apps, and other devices and software, the internet is “going dark.” These officials warn that encryption is restricting their access to information needed for criminal and national security investigations, arguing that they need a reliable, timely and scalable way to access it. Critics have raised legal and practical objections that regulations to ensure government access would pose unacceptable risks to privacy and civil liberties and undermine computer security in the face of rising cyber threats, and may be less necessary given the wider availability of data and alternative means of obtaining access to encrypted data. As the encryption debate has become increasingly polarized with participants on all sides making sweeping, sometimes absolutist, assertions, the new National Academies’ report doesn’t purport to tell anyone what to do, but rather provides a primer on the relevant issues.

These and other classified documents provided by former NSA contractor Edward Snowden reveal that the NSA has developed technology not just to record and transcribe private conversations but to automatically identify the speakers. Americans most regularly encounter this technology, known as speaker recognition, or speaker identification, when they wake up Amazon’s Alexa or call their bank. But a decade before voice commands like “Hello Siri” and “OK Google” became common household phrases, the NSA was using speaker recognition to monitor terrorists, politicians, drug lords, spies, and even agency employees. The technology works by analyzing the physical and behavioral features that make each person’s voice distinctive, such as the pitch, shape of the mouth, and length of the larynx. An algorithm then creates a dynamic computer model of the individual’s vocal characteristics. This is what’s popularly referred to as a “voiceprint.” The entire process — capturing a few spoken words, turning those words into a voiceprint, and comparing that representation to other “voiceprints” already stored in the database — can happen almost instantaneously. Although the NSA is known to rely on finger and face prints to identify targets, voiceprints, according to a 2008 agency document, are “where NSA reigns supreme.” It’s not difficult to see why. By intercepting and recording millions of overseas telephone conversations, video teleconferences, and internet calls — in addition to capturing, with or without warrants, the domestic conversations of Americans — the NSA has built an unrivaled collection of distinct voices. Documents from the Snowden archive reveal that analysts fed some of these recordings to speaker recognition algorithms that could connect individuals to their past utterances, even when they had used unknown phone numbers, secret code words, or multiple languages.

The classified documents, dating from 2004 to 2012, show the NSA refining increasingly sophisticated iterations of its speaker recognition technology. They confirm the uses of speaker recognition in counterterrorism operations and overseas drug busts. And they suggest that the agency planned to deploy the technology not just to retroactively identify spies like Pelton but to prevent whistleblowers like Snowden.

The United States, the United Kingdom and Australia have called on Facebook Inc to not go ahead with end-to-end encryption across its messaging services unless law enforcement officials have backdoor access, saying encryption hindered the fight against child abuse and terrorism.

The United States and United Kingdom also signed a special data agreement that would fast track requests from law enforcement to technology companies for information about the communications of terrorists and child predators. Law enforcement could get information in weeks or even days instead of the current wait of six months to two years. The latest tug-of-war between governments and tech companies over user data could also impact Apple Inc, Alphabet Inc’s Google and Microsoft Corp, as well as smaller encrypted chat apps like Signal.
