A study on PCG as a biometric approach

Phonocardiogram (PCG) is an emerging biometric modality that has seen about fifteen years of development. This paper provides a review of some of the most famous techniques that have been applied to the use of the PCG for biometric recognition. The paper also presents datasets used in PCG as well as the devices needed to capture them. PCG main modules are features extraction, reduction and classification schemes. The paper is concluded by a comparative analysis of the authentication performance of PCG biometric systems.
