securitas writes "The President's Commission on the U.S. Postal Service's final report (PDF) has recommended that the USPS and the Department of Homeland Security develop sender identification technology for all U.S. mail. The commission said Intelligent Mail could bolster security and let consumers track the progress of all mail they send, which has been a top consumer demand in surveys. The report released July 31 reads, "Each piece of Intelligent Mail will carry a unique, machine-readable barcode (or other indicia) that will identify, at a minimum, the sender, the destination, and the class of mail... Intelligent Mail will allow the real-time tracking of individual mail pieces." Privacy advocates like the EFF and Center for Democracy & Technology are understandably concerned. The Final Recommendations are available in PDF format. More at Direct Marketers News and pro-privacy/civil liberties magazine Counterpunch." Jamie adds: This confuses me, because I read a news story in late 2001 which matter-of-factly explained that authorities would be contacting recipients of letters which went through a particular post office around the same time as an anthrax envelope. The implication, which I haven't seen any discussion of then or since, is that records are kept of every letter's travels through every post office. Anyone know anything about that? Update: mec does.
