Google to Adopt New Privacy Measures

SAN FRANCISCO -- Google Inc. is adopting new privacy measures to make it more difficult to connect online search requests with the people making them _ a thorny issue that provoked a showdown with the U.S. government last year.
Under revisions announced late Wednesday, Google promised to wrap a cloak of anonymity around the vast amounts of information that the Mountain View-based company regularly collects about its millions of users around the world.
Google believes it can provide more assurances of privacy by removing key pieces of identifying information from its system every 18 to 24 months. The timetable is designed to comply with a hodgepodge of laws around the world that dictate how long search engines are supposed to retain user information.
Authorities still could demand to review personal information before Google purges it or take legal action seeking to force the company to keep the data beyond the new time limits.
Nevertheless, Google's additional safeguards mark the first time it has spelled out precisely how long it will hold onto data that can reveal intimate details about a person's Web surfing habits.
While Google will still retain reams of information about its users, the changes are supposed to lessen the chances that the company, a government agency or another party will be able to identify the people behind specific search requests.
Privacy experts applauded Google's precautions as a major step in the right direction.
"This is an extremely positive development," said Ari Schwartz, deputy director of the Center for Democracy and Technology. "It's the type of thing we have been advocating for a number of years."
Google is tightening its privacy standards a year after it became embroiled in a high-profile battle over the control of the user information that it had been stockpiling.
While gathering evidence for a case involving online pornography, the U.S. Justice Department subpoenaed the major search engines for lists of search requests made by their users.
While Yahoo Inc., Microsoft Corp.'s MSN and AOL all complied with parts of the legal demand, Google fought the request to protect its users' privacy. A federal judge ordered Google to turn over a small sampling of Web addresses contained in its search index, but decided the company didn't have to reveal the search requests sought by the government.
In another demonstration of the privacy risks posed by search engines, Time Warner Inc.'s AOL last summer released 19 million search requests on the Internet as part of a research project. Although only sets of numbers were attached to the requests, the information was used to identify some of the people behind the AOL searches.
