This document establishes terms and definitions in the field of biometric liveness detection and identifies characteristics of lifeless attacks and liveness detection methods, with analysis of lifeless attack instruments (LAIs). In addition, this document specifies liveness detection process and metrics. The following is outside of the scope of this document: Standardization of specific liveness detection methods; Detailed information about countermeasures, algorithms, or sensors; Overall system-level security; Security evaluation and vulnerability assessment; Integrated implementation of liveness detection subsystem within general biometric framework
