US Patent 11462050 Systems and methods of liveness determination

Embodiments include systems and methods of determining liveness of a biometric feature. A processor of a computing device may receive two or more scans of a biometric feature from a sensor of a source device. The processor may determine surface area rates of change of a surface area of the biometric feature, location stability rates of changes for one or more locations of the biometric feature, and presence information rates of change of the biometric feature. The processor may generate a liveness score based on the determined location stability rates of change, the surface area rates of change, and the presence information rates of change of the biometric feature. The processor may determine whether the generated liveness score meets a liveness threshold. The processor may determine that the biometric feature is a live biometric feature in response to determining that the generated liveness score meets the liveness threshold.
