Abstract
A computer-implemented method for improving security of a biometrics-based authentication system comprises receiving, by one or more servers, enrolled biometric samples of an enrolled user during an enrollment stage of the biometrics-based authentication system. Augmented biometric samples are created by adding learned perturbations to the enrolled biometric samples of the enrolled user. During a request for authentication, submitted biometric samples are received from a second user. The submitted biometric samples of the second user are compared to the enrolled biometric samples and to the augmented biometric samples of the enrolled user based on predefined metrics. Based on the comparison it is determined whether the submitted biometric samples of the second user have been modified to impersonate the enrolled user.
