Apple, always the innovator, is looking for the key to your heart. Security is a major concern in computing, particularly with smaller mobile devices becoming more capable. Apple thinks it has the answer.

The patent describes a method of detecting an authorized user by the pulse in the veins and arteries in the hand holding the device.

A sensor built into the device would detect your heart rhythm, apparently as unique as a fingerprint or retina. Other uses have been suggested, such as mood detection or managing user profiles.

I’ve not heard much about cardiac signatures before, but this strikes me as a more convenient solution than entering passwords, and far less hokey than the idea of holding up your eye to the camera for a retina scan. What a ‘handy’ way to solve the security issue.
