Google has sent a letter to U.S. Attorney General Eric Holder and FBI director Robert Mueller seeking permission to disclose specific details about the information it is required to provide to the government in response to requests for user data from U.S. intelligence agencies.
The letter, by Google's chief legal officer David Drummond, is part of an attempt by the company to correct what it says are misperceptions about the nature of the data it provides under Foreign Intelligence Surveillance Act (FISA) orders.
"We have always made clear that we comply with valid legal requests," Drummond said in a blog post today. "Assertions in the press that our compliance with these requests gives the U.S. government unfettered access to our users' data are simply untrue."
A recent report published by The Washington Post had identified Google as one of nine Internet companies from whom the government is directly collecting user data under a secret program called PRISM.
The story described PRISM as an anti-terror effort under which the NSA and the FBI were intercepting data directly from servers at Google, Microsoft, Facebook, YouTube, Skype and other Internet companies.
Though details of PRISM program are new, the FBI and other intelligence agencies have in the past made no secret of their desire to monitor real-time traffic on Facebook and other sites for signs of terrorist activity. For example, in a request for information last year, the FBI said it was seeking technology that would help it quickly gather and analyze data posted on sites such as Facebook, Twitter and on blogs using simple keyword searches and phrases such as "bomb," "suspicious package," "white powder," "active shoot" and "school lock down."
The FBI has noted that such technology is vital to helping it monitor real-time communications by terrorists and suspected terrorists on these sites.
The Post report came just one day after The Guardian published a dramatic story about a secret NSA phone call records collection program. The stories have sparked considerable concern about extensive domestic surveillance by U.S. intelligence agencies.
Google, Facebook, Microsoft and the others have categorically denied that they have ever voluntarily provided any user data to the government. Though a slide from a classified document obtained by the Post appeared to show that the government was collecting user data directly from servers at these companies, all the firms named in the document have flatly denied this is happening.
The apparent disconnect between the information in the slides and the denials by the companies has fueled speculation on the nature of PRISM technology and how exactly it is being used.
In his letter, Drummond noted that Google has been able to do little to address the speculation because it is barred from speaking about the FISA requests it gets under government nondisclosure agreements.
