For our July 2013 issue, we review recent patents in the area of liveness detection. With the increasing proliferation of biometric authentication schemes, it is a challenge for devices to determine whether a biometric supplied for authentication is being provided by a real person, rather then being a spoof, such as a picture of a person's face, or a latex patch imprinted with realistic fingerprint ridges. We present below recent IP in this field:
