Abstract
An optical sensing device can receive a speckle pattern generated by a laser's interaction with acoustically stimulated tissue. A computing device can identify one or more characteristics within the received speckle pattern. The computing device can then identify a match of the one or more characteristics to a user biometric signature stored within a storage device. Based upon the identified match, the system can authenticate a user within a computer system.
