Abstract
In certain embodiments of the present disclosure relate to a method for detecting liveness of a user during biometric authentication. The method comprising identifying a speech signal in a pre-determined time interval associated with the speech signal. Furthermore, the method comprising determining a speech respiration co-occurrence (SRC) score associated with the speech signal. In addition, the method comprising detecting liveness of the user, if the SRC score is above a predefined threshold, wherein the detection of liveness further aids in increasing the security of biometric authentication system.
