On March 26, 2009, the US Patent & Trademark Office published an Apple patent application relating to an advanced embedded biometric authentication security system that will be implemented on all of Apple's future hardware from the iPhone to the MacBook. Devices will be able to authenticate the user by comparing the detected identification information with identification information stored in a library of the device. For example, the sensor may include a sensor for detecting features of a user's skin, or features underneath a user's skin. Other methods include fingerprint technology, face recognition, ear canal sensory, and in the case of the iPhone, voice recognition to identify just a few of the security features being considered. If you happen to be creeped out by fingerprint identification security methods, then Apple has come up with a unique alternative methodology called Temporal Pattern which is worth noting. Apple's security features will be able to protect the entire users system or just a few special apps or specific data that the user identifies as being important. Apple has also inventively devised a time-based security feature that would shut down the use of a particular app after a specific time that's assigned to it. All in all, the forthcoming biometric security system options presented are world class and bound to be of great assistance to Apple as they push further into the enterprise market.
