JagsLive makes note of a story investigative whether Google's recent commitment to anonymize IP logs faster is really as good as it sounds. We discussed their announcement a few days ago. CNet's Chris Soghoian takes a closer look: "While the company hasn't said how it de-identifies the cookies, it has revealed in public statements that its IP anonymization tactics consists of chopping off the last 8 bits of a user's IP address. As an example, an IP address of a home user could be 173.192.103.121. After 18 months, Google chops this down to 173.192.103.XXX. Since each octet (the numbers between each period of an IP) can contain values from 1-255, Google's anonymization modus allows a user, at most, to hide among 254 other computers. ... Google has now revealed that it will change "some" of the bits of the IP address after 9 months, but less than the eight bits that it masks after the full 18 months. Thus, instead of Google's barter being able to hide among 254 other report superhighway users, perhaps they'll be able to hide among 64, or 127 other possible IP addresses. By itself, this is a laughable level of anonymity. However, it gets worse."
