Using fingerprint and facial recognition as shown here, Intel demonstrated how we might one day be able to dispense with our house keys. The system here doesn't recognize just a single person, either. It can identify each of the people in a group. If two of the people in the group aren't authorized, or the entire group isn't authorized for a certain time of day, too bad. Johnny can't bring his pals into the house to get on the gaming console when he should be doing his homework alone. Is Johnny being a good boy? Then mom can provide access to him and his buddies via her cell phone. Intel also is exploring how other individual traits--someone's gait or a particular mannerism--could be applied to a security system. These recognition technologies could find other uses, too. As part of this exhibit a researcher walked up to a camera and, when it recognized him, the system displayed his calendar on the wall. How could you ever forget a date when it's in your face?
