Serial number as a third form of identification.

The security codes to be embedded in Intel_s Pentium III processor can potentially be misused to identify and collect data on Web surfers, some privacy advocates warn. But Intel argues that the technology will actually make the Net a safer place. The controversy has emerged as 30 Web sites prepare to conduct trials of the processor, to be released in February. Critics claim that the number scheme can be used to monitor the Internet habits of virtually anyone with a modern, Intel-based computer. Intel countered that the serial number will actually improve security. The Web sites in the trials, for instance, will use the serial number as a third form of identification, complementing the user name and password schemes currently in place, said Pat Gelsinger, corporate vice president of the Desktop Products Group at Intel. Ideally, hackers couldn_t just assume your identity by swiping your user name and cracking a password; they would have to steal your computer as well.
