CONTROLLED ACCESS TO FUNCTIONALITY OF A WIRELESS DEVICE
First Claim
1. An apparatus, comprisingan electronic device comprising a processor, a memory, and a camera, wherein the device is to:
- obtain a first biometric measurement of a part of a person'"'"'s body;
initiate a physical change in the part;
obtain a second biometric measurement of the part subsequent to the change; and
verify that the second measurement is different than the first measurement.

Abstract
Various embodiments of the invention may be used to verify that a person being authorized by biometric techniques to use a device is a living person and not some form of recording intended to spoof the system. Some embodiments may try to cause a change in a measured biometric feature, and compare images taken before and after the change to verify the change occurred. In some embodiments, multiple stages of verification may be used, either to increase the difficulty of spoofing the security system, or to provide different levels of security for different levels of access to the device'"'"'s functionality.
