Kaan writes: "Japan just launched a mandatory, nationwide ID system whereby every citizen is assigned an 11-digit identification number. The database stores personal data (name, address, date of birth, gender, possibly more data) for each person. At least five municipalities are refusing to join the system, which accounts for ~4 million of the 127 million total. While some Japanese folks are refusing to cooperate, most are going along with it. Is this the beginning of the end of privacy in Japan? How much longer until we see something like that in the U.S.?"
