Taking Spying to Higher Level, Agencies Look for More Ways to Mine Data


By JOHN MARKOFF

(snip - a long article, 3 web pages)

Much of the recent work on data mining has been aimed at even more sophisticated applications. The National Security Agency has invested billions in computerized tools for monitoring phone calls around the world not only logging them, but also determining content and more recently in trying to design digital vacuum cleaners to sweep up information from the Internet.

Last September, the N.S.A. was granted a patent for a technique that could be used to determine the physical location of an Internet address another potential category of data to be mined. The technique, which exploits the tiny time delays in the transmission of Internet data, suggests the agency's interest in sophisticated surveillance tasks like trying to determine where a message sent from an Internet address in a cybercafe might have originated.

An earlier N.S.A. patent, in 1999, focused on a software solution for generating a list of topics from computer-generated text. Such a capacity hints at the ability to extract the content of telephone conversations automatically. That might permit the agency to mine millions of phone conversations and then select a handful for human inspection.

In 2003, Virage, a Silicon Valley company, began supplying a voice transcription product that recognized and logged the text of television programming for government and commercial customers. Under perfect conditions, the system could be 95 percent accurate in capturing spoken text. Such technology has potential applications in monitoring phone conversations as well.
