Liveness Detection for Face Recognition in Biometrics: A Review
Meenakshi Saini · IOSR Journal of Computer Engineering · 2016
A Biometric system recognizes an individual by measuring or analyzing his physical or behavioral body traits.In recent times, Facial recognition is one of the most commonly used biometric technology and is rapidly integrated in various applications such as security login or access to the buildings or surveillance etc. Facial recognition is also user friendly and cost effective solution than other technologies.Beside this, Face recognition system is also prone to the spoofing attacks such as placing photographs,playing video clips in front of camera and dummy faces.In order to guard the system against such spoofing attacks,liveness detection can be integrated into the system.Liveness detection in face recognition tests whether the face presented to the system is real face or a fake face.This paper presents the state-of-the-art of various liveness detection techniques in the area of face recognition technology along with their strengths and limitations.
