mytrip brings us a news.com story about the FBI's efforts to make records of users' activities available to law enforcement for a much longer time. Several members of Congress also lent their support to the idea that such data retention should be mandatory for a period of up to 2 years. Quoting: "Based on the statements at Wednesday's hearing and previous calls for new laws in this area, the scope of a mandatory data retention law remains fuzzy. It could mean forcing companies to store data for two years about what Internet addresses are assigned to which customers (Comcast said in 2006 that it would be retaining those records for six months). Or it could be far more intrusive. It could mean keeping track of e-mail and instant messaging correspondents and what Web pages users visit. Some Democratic politicians have called for data retention laws to extend to domain name registries and Web hosting companies and even social networking sites."
