When you visit a website, online trackers and the site itself may be able to identify you – even if you’ve installed software to protect yourself. It’s possible to configure your browser to thwart tracking, but many people don’t know how. Panopticlick will analyze how well your browser and add-ons protect you against online tracking techniques. We’ll also see if your system is uniquely configured—and thus identifiable—even if you are using privacy-protective software.

Only anonymous data will be collected through this site. Panopticlick is a research project of the Electronic Frontier Foundation. Learn more

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.

Paley avoided traditional film distribution deals and instead released the film under a Creative Commons Attribution-Share Alike license, writing: You don't need my permission to copy, share, publish, archive, show, sell, broadcast, or remix Sita Sings the Blues. Conventional wisdom urges me to demand payment for every use of the film, but then how would people without money get to see it? How widely would the film be disseminated if it were limited by permission and fees? Control offers a false sense of security. The only real security I have is trusting you, trusting culture, and trusting freedom

For the past few months I’ve been covering U.S. government funding of popular Internet privacy tools like Tor, CryptoCat and Open Whisper Systems. During my reporting, one agency in particular keeps popping up: An agency with one of those really bland names that masks its wild, bizarre history: the Broadcasting Board of Governors, or BBG. The BBG was formed in 1999 and runs on a $721 million annual budget. It reports directly to Secretary of State John Kerry and operates like a holding company for a host of Cold War-era CIA spinoffs and old school “psychological warfare” projects: Radio Free Europe, Radio Free Asia, Radio Martí, Voice of America, Radio Liberation from Bolshevism (since renamed “Radio Liberty”) and a dozen other government-funded radio stations and media outlets pumping out pro-American propaganda across the globe. Today, the Congressionally-funded federal agency is also one of the biggest backers of grassroots and open-source Internet privacy technology. These investments started in 2012, when the BBG launched the “Open Technology Fund” (OTF) — an initiative housed within and run by Radio Free Asia (RFA), a premier BBG property that broadcasts into communist countries like North Korea, Vietnam, Laos, China and Myanmar. The BBG endowed Radio Free Asia’s Open Technology Fund with a multimillion dollar budget and a single task: “to fulfill the U.S. Congressional global mandate for Internet freedom.”

Here’s a small sample of what the Broadcasting Board of Governors funded (through Radio Free Asia and then through the Open Technology Fund) between 2012 and 2014: Open Whisper Systems, maker of free encrypted text and voice mobile apps like TextSecure and Signal/RedPhone, got a generous $1.35-million infusion. (Facebook recently started using Open Whisper Systems to secure its WhatsApp messages.) CryptoCat, an encrypted chat app made by Nadim Kobeissi and promoted by EFF, received $184,000. LEAP, an email encryption startup, got just over $1 million. LEAP is currently being used to run secure VPN services at RiseUp.net, the radical anarchist communication collective. A Wikileaks alternative called GlobaLeaks (which was endorsed by the folks at Tor, including Jacob Appelbaum) received just under $350,000. The Guardian Project — which makes an encrypted chat app called ChatSecure, as well a mobile version of Tor called Orbot — got $388,500. The Tor Project received over $1 million from OTF to pay for security audits, traffic analysis tools and set up fast Tor exit nodes in the Middle East and South East Asia.

Yahoo Chief Information Security Officer Alex Stamos announced today at Black Hat 2014 that starting in the fall of this year, the purple-hued company will begin giving users the option of seamlessly wrapping their e-mails in PGP encryption. According to Kashmir Hill at Forbes, the encryption capability will be offered through a modified version of the same End-to-End browser plug-in that Google uses for PGP in Gmail. The announcement was tweeted by Yan Zhu, who has reportedly been hired by Yahoo to adapt End-to-End for use with Yahoo Mail. Zhu formerly worked as an engineer at the Electronic Frontier Foundation, an organization that has consistently been outspoken in its call for the widespread use of encryption throughout the Web and the Internet in general.

Gagging orders in the FBI's National Security Letters are all above board and constitutional, a California court has ruled. These security letters are typically sent to internet giants demanding information on whoever is behind a username or email address. Crucially, these requests include clauses that prevent the organizations from warning specific subscribers that they are under surveillance by the Feds. Cloudflare and Credo Mobile aren't happy with that, and – with the help of rights warriors at the EFF – challenged the gagging orders. Despite earlier successes in their legal battle, the 9th US Circuit Court of Appeals ruled [PDF] on Monday that the gagging orders do not trample on First Amendment rights.

The FBI dishes out thousands of National Security Letters (NSLs) every year; they can simply be issued by a special agent in charge in a bureau field office, and don’t require judicial review. They allow the Feds to obtain the name, address, and records of any services used – but not the contents of conversations – plus billing records of a person, and forbid the hosting company from telling the subject, meaning those under investigation can’t challenge the decision. It used to be the case that companies couldn’t even mention the existence of the NSL system for fear of prosecution. However, in 2013 a US district court in San Francisco ruled that such extreme gagging violated the First Amendment. That decision came after Google, and later others, started publishing the number of NSL orders that had been received, in defiance of the law. In 2015 the Obama administration amended the law to allow companies limited rights to disclose NSL orders, and to set a three-year limit for the gagging order. It also set up a framework for companies to challenge the legitimacy of NSL subpoenas, and it was these changes that caused the appeals court verdict in favor of the government.

Reporters Without Borders (RSF) released its annual “Enemies of the Internet” index this week—a ranking first launched in 2006 intended to track countries that repress online speech, intimidate and arrest bloggers, and conduct surveillance of their citizens.  Some countries have been mainstays on the annual index, while others have been able to work their way off the list.  Two countries particularly deserving of praise in this area are Tunisia and Myanmar (Burma), both of which have stopped censoring the Internet in recent years and are headed in the right direction toward Internet freedom. In the former category are some of the world’s worst offenders: Cuba, North Korea, China, Iran, Saudi Arabia, Vietnam, Belarus, Bahrain, Turkmenistan, Syria.  Nearly every one of these countries has amped up their online repression in recent years, from implementing sophisticated surveillance (Syria) to utilizing targeted surveillance tools (Vietnam) to increasing crackdowns on online speech (Saudi Arabia).  These are countries where, despite advocacy efforts by local and international groups, no progress has been made. The newcomers  A third, perhaps even more disheartening category, is the list of countries new to this year's index.  A motley crew, these nations have all taken new, harsh approaches to restricting speech or monitoring citizens:

United States: This is the first time the US has made it onto RSF’s list.  While the US government doesn’t censor online content, and pours money into promoting Internet freedom worldwide, the National Security Agency’s unapologetic dragnet surveillance and the government’s treatment of whistleblowers have earned it a spot on the index. United Kingdom: The European nation has been dubbed by RSF as the “world champion of surveillance” for its recently-revealed depraved strategies for spying on individuals worldwide.  The UK also joins countries like Ethiopia and Morocco in using terrorism laws to go after journalists.  Not noted by RSF, but also important, is the fact that the UK is also cracking down on legal pornography, forcing Internet users to opt-in with their ISP if they wish to view it and creating a slippery slope toward overblocking.  This is in addition to the government’s use of an opaque, shadowy NGO to identify child sexual abuse images, sometimes resulting instead in censorship of legitimate speech.
