Undetectable "Son of Cookies": Scottish Enterprise is developing a new, advanced "sensor" system to monitor websurfers without relying on computer cookies. These "sensors" can monitor individual keystrokes, can be altered remotely, and are "almost impossible to detect". But privacy advocates should fear not, for the developers assure us that "[s]afeguards to prevent misuse of the software will be developed at the same time as the program itself." Ok, I feel much better now. (Links via The Register.)
