So you like the idea of biometrics for the guaranteed uniqueness of user IDs but don't want to impose retinal scans or fingerprinting on your company's ranks? Here's a less intrusive but equally unique personal identifier: your typing style.
Software from BioPassword Inc. records users' so-called keyboard dynamics, which then authenticate the typist upon login (see www.biopassword.com). One CIO we know deployed it so that employees could access the company's thin-client network from any browser without cumbersome security measures like tokens (or DNA samples). Now that's a solution even a card-carrying member of the ACLU could love.
