Yahoo to shorten logs of user activity to 3 months

(AP)
Yahoo will shorten the amount of time that it retains data about its users' online behavior — including Internet search records — to three months from 13 months and expand the range of data that it "anonymizes" after that period. Yahoo's announcement ratchets up the pressure on rivals Google and Microsoft to follow its lead. In September, Google said it would "anonymize," or mask, the numeric Internet Protocol (IP) addresses on its server logs after nine months, down from a previous retention period of 18 months. And Microsoft, which currently keeps user data for 18 months, said it would support an industry standard of six months.
