surveillance state NSA NSA-targets must-read

  • The NSA’s spying on everyone’s metadata can tell them just about everything about us … and it violates our Constitutional right to freedom of association. But people are getting distracted from the big picture by focusing on metadata. As security expert Bruce Schneier wrote yesterday: What frustrates me about all of this — [the Privacy and Civil Liberties Oversight Board] report, the president’s speech, and so many other things — is that they focus on the bulk collection of cell phone call records. There’s so much more bulk collection going on — phone calls, e-mails, address books, buddy lists, text messages, cell phone location data, financial documents, calendars, [smartphone apps] etc. — and we really need legislation and court opinions on it all. But because cell phone call records were the first disclosure, they’re what gets the attention. Indeed, Schneier confirmed last October what we’ve been saying for years … don’t get too distracted by the details, because the government is spying on everything:
  • Honestly, I think the details matter less and less. We have to assume that the NSA has EVERYONE who uses electronic communications under CONSTANT surveillance. New details about hows and whys will continue to emerge …but the big picture will remain the same. He’s right. As just one example, there is substantial evidence from top NSA and FBI whistleblowers that the government is recording the content of our calls and emails … word-for-word. So what should we make of the government’s denials that it records content? Given that the government has been caught lying about spying again and again, I’m not sure how much weight we should give to such denials. NSA whistleblower Russ Tice notes: They’re collecting content … word-for-word. *** You can’t trust these people. They lie, and they lie a lot.

    Personally, I don't think the focus is on metadata because it was the first target exposed. I see it more as a propaganda weapon to divert attention from the other NSA targets.  In any event, this page offers a very comprehensive list of the types of data the NSA is collecting, with links to further information on each type.

surveillance state Snowden nytimes amnesty

shared by Paul Merrell on 04 Jan 14 - No Cached
  • Considering the enormous value of the information he has revealed, and the abuses he has exposed, Mr. Snowden deserves better than a life of permanent exile, fear and flight. He may have committed a crime to do so, but he has done his country a great service. It is time for the United States to offer Mr. Snowden a plea bargain or some form of clemency that would allow him to return home, face at least substantially reduced punishment in light of his role as a whistle-blower, and have the hope of a life advocating for greater privacy and far stronger oversight of the runaway intelligence community.

    The New York Times comes out in an editorial by its Editorial Board, calling for amnesty for Edward Snowden. To my knowledge, this is the first mainstream media outlet to do so.

How the NSA Converts Spoken Words Into Searchable Text - The Intercept - 0 views

  • Most people realize that emails and other digital communications they once considered private can now become part of their permanent record. But even as they increasingly use apps that understand what they say, most people don’t realize that the words they speak are not so private anymore, either. Top-secret documents from the archive of former NSA contractor Edward Snowden show the National Security Agency can now automatically recognize the content within phone calls by creating rough transcripts and phonetic representations that can be easily searched and stored. The documents show NSA analysts celebrating the development of what they called “Google for Voice” nearly a decade ago.

The documents show NSA analysts celebrating the development of what they called “Google for Voice” nearly a decade ago.
  • Though perfect transcription of natural conversation apparently remains the Intelligence Community’s “holy grail,” the Snowden documents describe extensive use of keyword searching as well as computer programs designed to analyze and “extract” the content of voice conversations, and even use sophisticated algorithms to flag conversations of interest. The documents include vivid examples of the use of speech recognition in war zones like Iraq and Afghanistan, as well as in Latin America. But they leave unclear exactly how widely the spy agency uses this ability, particularly in programs that pick up considerable amounts of conversations that include people who live in or are citizens of the United States.

  • The Defense Department, through its Defense Advanced Research Projects Agency (DARPA), started funding academic and commercial research into speech recognition in the early 1970s. What emerged were several systems to turn speech into text, all of which slowly but gradually improved as they were able to work with more data and at faster speeds. In a brief interview, Dan Kaufman, director of DARPA’s Information Innovation Office, indicated that the government’s ability to automate transcription is still limited. Kaufman says that automated transcription of phone conversation is “super hard,” because “there’s a lot of noise on the signal” and “it’s informal as hell.”
  • A 2008 document from the Snowden archive shows that  transcribing news broadcasts was already working well seven years ago, using a program called Enhanced Video Text and Audio Processing: (U//FOUO) EViTAP is a fully-automated news monitoring tool. The key feature of this Intelink-SBU-hosted tool is that it analyzes news in six languages, including Arabic, Mandarin Chinese, Russian, Spanish, English, and Farsi/Persian. “How does it work?” you may ask. It integrates Automatic Speech Recognition (ASR) which provides transcripts of the spoken audio. Next, machine translation of the ASR transcript translates the native language transcript to English. Voila! Technology is amazing. A version of the system the NSA uses is now even available commercially.
  • But even then, a newer, more sophisticated product was already being rolled out by the NSA’s Human Language Technology (HLT) program office. The new system, called VoiceRT, was first introduced in Baghdad, and “designed to index and tag 1 million cuts per day.” The goal, according to another 2006 memo, was to use voice processing technology to be able “index, tag and graph,” all intercepted communications. “Using HLT services, a single analyst will be able to sort through millions of cuts per day and focus on only the small percentage that is relevant,” the memo states. A 2009 memo from the NSA’s British partner, GCHQ, describes how “NSA have had the BBN speech-to-text system Byblos running at Fort Meade for at least 10 years. (Initially they also had Dragon.) During this period they have invested heavily in producing their own corpora of transcribed Sigint in both American English and an increasing range of other languages.” (GCHQ also noted that it had its own small corpora of transcribed voice communications, most of which happened to be “Northern Irish accented speech.”)
  • According to a 2011 memo, “How is Human Language Technology (HLT) Progressing?“, NSA that year deployed “HLT Labs” to Afghanistan, NSA facilities in Texas and Georgia, and listening posts in Latin America run by the Special Collection Service, a joint NSA/CIA unit that operates out of embassies and other locations. “Spanish is the most mature of our speech-to-text analytics,” the memo says, noting that the NSA and its Special Collections Service sites in Latin America, have had “great success searching for Spanish keywords.”
  • The Snowden archive, as searched and analyzed by The Intercept, documents extensive use of speech-to-text by the NSA to search through international voice intercepts — particularly in Iraq and Afghanistan, as well as Mexico and Latin America. For example, speech-to-text was a key but previously unheralded element of the sophisticated analytical program known as the Real Time Regional Gateway (RTRG), which started in 2005 when newly appointed NSA chief Keith B. Alexander, according to the Washington Post, “wanted everything: Every Iraqi text message, phone call and e-mail that could be vacuumed up by the agency’s powerful computers.” The Real Time Regional Gateway was credited with playing a role in “breaking up Iraqi insurgent networks and significantly reducing the monthly death toll from improvised explosive devices.” The indexing and searching of “voice cuts” was deployed to Iraq in 2006. By 2008, RTRG was operational in Afghanistan as well.
  • VoiceRT, in turn, was surpassed a few years after its launch. According to the intelligence community’s “Black Budget” for fiscal year 2013, VoiceRT was decommissioned and replaced in 2011 and 2012, so that by 2013, NSA could operationalize a new system. This system, apparently called SPIRITFIRE, could handle more data, faster. SPIRITFIRE would be “a more robust voice processing capability based on speech-to-text keyword search and paired dialogue transcription.”
  • What’s less clear from the archive is how extensively this capability is used to transcribe or otherwise index and search voice conversations that primarily involve what the NSA terms “U.S. persons.” The NSA did not answer a series of detailed questions about automated speech recognition, even though an NSA “classification guide” that is part of the Snowden archive explicitly states that “The fact that NSA/CSS has created HLT models” for speech-to-text processing as well as gender, language and voice recognition, is “UNCLASSIFIED.”
  • Also unclassified: The fact that the processing can sort and prioritize audio files for human linguists, and that the statistical models are regularly being improved and updated based on actual intercepts. By contrast, because they’ve been tuned using actual intercepts, the specific parameters of the systems are highly classified.
  • The presidentially appointed but independent Privacy and Civil Liberties Oversight Board (PCLOB) didn’t mention speech-to-text technology in its public reports. “I’m not going to get into whether any program does or does not have that capability,” PCLOB chairman David Medine told The Intercept. His board’s reports, he said, contained only information that the intelligence community agreed could be declassified.

ACLU accuses NSA of using holiday lull to 'minimise impact' of documents | US news | Th... - 0 views

surveillance state NSA internal-reports FOIA litigation ACLU

shared by Paul Merrell on 29 Dec 14 - No Cached
  • The National Security Agency used the holiday lull to “minimise the impact” of a tranche of documents by releasing them on Christmas Eve, the American Civil Liberties Union (ACLU) said on Friday. The documents, which were released in response to a legal challenge by the ACLU under the Freedom of Information Act, are heavily – in some places totally –redacted versions of reports by the NSA to the President’s Intelligence Oversight Board dating back to 2007. A court ordered the documents released this past summer, and a 22 December deadline for that release was agreed upon, according to Patrick Toomey, a staff attorney at the ACLU’s national security project, because the NSA said it needed “six or seven months” to complete its review and redaction process. A spokesperson for the NSA said that the 22 December deadline, “which was agreed to by all parties,” was met.
  • But according to Toomey, the ACLU didn’t receive the documents until “late in the day on the 23rd” – the NSA sent them by FedEx late on the 22nd – and the NSA didn’t publicly release them until Christmas Eve. “I certainly think the NSA would prefer to have the documents released right ahead of the holidays in order to have less public attention on what they contain,” Toomey said. The redactions on the document are extreme, and their omissions tantalising. One entry, from the 4th quarter of 2008, reads: “On [redacted] [redacted] used the US SIGINT System (USSS) to locate [redacted] believed to be kidnapped [redacted] The selectors were tasked before authorization was obtained from NSA. After the NSA Office of General Counsel (OGC) denied the authorization request, [redacted] was found. He had not been kidnapped.” Another reads: “On [redacted] during an experimental collection and processing effort, NSA analysts collected [several lines of text redacted.] The messages were deleted [redacted] when the error was identified.”
  • Many entries are erased entirely, which means the documents reveal very little about how individuals who misuse the data were disciplined by the NSA, or how quickly errors were resolved. But, according to Toomey, they speak to a total picture of a “large number of different compliance violations. We don’t know how many.” He said the documents deepen the picture of the nature and extent of compliance violations by analysts working for the NSA.

  • “There are certain portions of the documents that really vindicate some of the things [Edward] Snowden said when he first described the NSA surveillance in terms of the ability of analysts to conduct queries – without authorisation – of raw internet traffic,” Toomey said. Among the items redacted are sections detailing the total number of violations reported, with many ending up like this entry from 2013 “On [redacted] occasions during the fourth quarter, selectors were incorrectly tasked because of typographical errors.” This makes the scale of the problem difficult to gauge. Toomey said the ACLU would continue to sue for the release of those numbers. “More generally,” Toomey said, “just the range of different compliance violations makes it clear that at every step of the NSA’s collection of information there are vulnerabilities that leave the privacy of Americans at risk.”

The Latest Rules on How Long NSA Can Keep Americans' Encrypted Data Look Too Familiar |... - 0 views

surveillance state NSA IAA-2015 Sect-309 legislation

shared by Paul Merrell on 26 Jan 15 - No Cached
  • Does the National Security Agency (NSA) have the authority to collect and keep all encrypted Internet traffic for as long as is necessary to decrypt that traffic? That was a question first raised in June 2013, after the minimization procedures governing telephone and Internet records collected under Section 702 of the Foreign Intelligence Surveillance Act were disclosed by Edward Snowden. The issue quickly receded into the background, however, as the world struggled to keep up with the deluge of surveillance disclosures. The Intelligence Authorization Act of 2015, which passed Congress this last December, should bring the question back to the fore. It established retention guidelines for communications collected under Executive Order 12333 and included an exception that allows NSA to keep ‘incidentally’ collected encrypted communications for an indefinite period of time. This creates a massive loophole in the guidelines. NSA’s retention of encrypted communications deserves further consideration today, now that these retention guidelines have been written into law. It has become increasingly clear over the last year that surveillance reform will be driven by technological change—specifically by the growing use of encryption technologies. Therefore, any legislation touching on encryption should receive close scrutiny.
  • Section 309 of the intel authorization bill describes “procedures for the retention of incidentally acquired communications.” It establishes retention guidelines for surveillance programs that are “reasonably anticipated to result in the acquisition of [telephone or electronic communications] to or from a United States person.” Communications to or from a United States person are ‘incidentally’ collected because the U.S. person is not the actual target of the collection. Section 309 states that these incidentally collected communications must be deleted after five years unless they meet a number of exceptions. One of these exceptions is that “the communication is enciphered or reasonably believed to have a secret meaning.” This exception appears to be directly lifted from NSA’s minimization procedures for data collected under Section 702 of FISA, which were declassified in 2013. 
  • While Section 309 specifically applies to collection taking place under E.O. 12333, not FISA, several of the exceptions described in Section 309 closely match exceptions in the FISA minimization procedures. That includes the exception for “enciphered” communications. Those minimization procedures almost certainly served as a model for these retention guidelines and will likely shape how this new language is interpreted by the Executive Branch. Section 309 also asks the heads of each relevant member of the intelligence community to develop procedures to ensure compliance with new retention requirements. I expect those procedures to look a lot like the FISA minimization guidelines.

  • This language is broad, circular, and technically incoherent, so it takes some effort to parse appropriately. When the minimization procedures were disclosed in 2013, this language was interpreted by outside commentators to mean that NSA may keep all encrypted data that has been incidentally collected under Section 702 for at least as long as is necessary to decrypt that data. Is this the correct interpretation? I think so. It is important to realize that the language above isn’t just broad. It seems purposefully broad. The part regarding relevance seems to mirror the rationale NSA has used to justify its bulk phone records collection program. Under that program, all phone records were relevant because some of those records could be valuable to terrorism investigations and (allegedly) it isn’t possible to collect only those valuable records. This is the “to find a needle a haystack, you first have to have the haystack” argument. The same argument could be applied to encrypted data and might be at play here.
  • This exception doesn’t just apply to encrypted data that might be relevant to a current foreign intelligence investigation. It also applies to cases in which the encrypted data is likely to become relevant to a future intelligence requirement. This is some remarkably generous language. It seems one could justify keeping any type of encrypted data under this exception. Upon close reading, it is difficult to avoid the conclusion that these procedures were written carefully to allow NSA to collect and keep a broad category of encrypted data under the rationale that this data might contain the communications of NSA targets and that it might be decrypted in the future. If NSA isn’t doing this today, then whoever wrote these minimization procedures wanted to at least ensure that NSA has the authority to do this tomorrow.
  • There are a few additional observations that are worth making regarding these nominally new retention guidelines and Section 702 collection. First, the concept of incidental collection as it has typically been used makes very little sense when applied to encrypted data. The way that NSA’s Section 702 upstream “about” collection is understood to work is that technology installed on the network does some sort of pattern match on Internet traffic; say that an NSA target uses example@gmail.com to communicate. NSA would then search content of emails for references to example@gmail.com. This could notionally result in a lot of incidental collection of U.S. persons’ communications whenever the email that references example@gmail.com is somehow mixed together with emails that have nothing to do with the target. This type of incidental collection isn’t possible when the data is encrypted because it won’t be possible to search and find example@gmail.com in the body of an email. Instead, example@gmail.com will have been turned into some alternative, indecipherable string of bits on the network. Incidental collection shouldn’t occur because the pattern match can’t occur in the first place. This demonstrates that, when communications are encrypted, it will be much harder for NSA to search Internet traffic for a unique ID associated with a specific target.
  • This lends further credence to the conclusion above: rather than doing targeted collection against specific individuals, NSA is collecting, or plans to collect, a broad class of data that is encrypted. For example, NSA might collect all PGP encrypted emails or all Tor traffic. In those cases, NSA could search Internet traffic for patterns associated with specific types of communications, rather than specific individuals’ communications. This would technically meet the definition of incidental collection because such activity would result in the collection of communications of U.S. persons who aren’t the actual targets of surveillance. Collection of all Tor traffic would entail a lot of this “incidental” collection because the communications of NSA targets would be mixed with the communications of a large number of non-target U.S. persons. However, this “incidental” collection is inconsistent with how the term is typically used, which is to refer to over-collection resulting from targeted surveillance programs. If NSA were collecting all Tor traffic, that activity wouldn’t actually be targeted, and so any resulting over-collection wouldn’t actually be incidental. Moreover, greater use of encryption by the general public would result in an ever-growing amount of this type of incidental collection.
  • This type of collection would also be inconsistent with representations of Section 702 upstream collection that have been made to the public and to Congress. Intelligence officials have repeatedly suggested that search terms used as part of this program have a high degree of specificity. They have also argued that the program is an example of targeted rather than bulk collection. ODNI General Counsel Robert Litt, in a March 2014 meeting before the Privacy and Civil Liberties Oversight Board, stated that “there is either a misconception or a mischaracterization commonly repeated that Section 702 is a form of bulk collection. It is not bulk collection. It is targeted collection based on selectors such as telephone numbers or email addresses where there’s reason to believe that the selector is relevant to a foreign intelligence purpose.” The collection of Internet traffic based on patterns associated with types of communications would be bulk collection; more akin to NSA’s collection of phone records en mass than it is to targeted collection focused on specific individuals. Moreover, this type of collection would certainly fall within the definition of bulk collection provided just last week by the National Academy of Sciences: “collection in which a significant portion of the retained data pertains to identifiers that are not targets at the time of collection.”
  • The Section 702 minimization procedures, which will serve as a template for any new retention guidelines established for E.O. 12333 collection, create a large loophole for encrypted communications. With everything from email to Internet browsing to real-time communications moving to encrypted formats, an ever-growing amount of Internet traffic will fall within this loophole.

    Tucked into a budget authorization act in December without press notice. Section 309 (the Act is linked from the article) appears to be very broad authority for the NSA to intercept any form of telephone or other electronic information in bulk. There are far more exceptions from the five-year retention limitation than the encrypted information exception. When reading this, keep in mind that the U.S. intelligence community plays semantic games to obfuscate what it does. One of its word plays is that communications are not "collected" until an analyst looks at or listens to partiuclar data, even though the data will be searched to find information countless times before it becomes "collected." That searching was the major basis for a decision by the U.S. District Court in Washington, D.C. that bulk collection of telephone communications was unconstitutional: Under the Fourth Amendment, a "search" or "seizure" requiring a judicial warrant occurs no later than when the information is intercepted. That case is on appeal, has been briefed and argued, and a decision could come any time now. Similar cases are pending in two other courts of appeals. Also, an important definition from the new Intelligence Authorization Act: "(a) DEFINITIONS.-In this section: (1) COVERED COMMUNICATION.-The term ''covered communication'' means any nonpublic telephone or electronic communication acquired without the consent of a person who is a party to the communication, including communications in electronic storage."
