Abstract: The present disclosure provides systems and techniques for authenticating biometric data while protecting user privacy. Aspects of the present disclosure include collecting biometric query data at a biometric sensor of the gun, generating a set of query features from the biometric query data, each query feature of the set of query features including a first number of dimensions, generating a projection matrix, each element of the projection matrix being drawn independently from an identical distribution having zero mean and unit variance, transforming the set of query features into a transformed set of query features according to the projection matrix, retrieving a transformed set of enrollment features from memory of the gun, identifying a data match based on the transformed set of query features and the transformed set of enrollment features satisfying a similarity threshold, and unlocking the gun in response to the identifying the data match.
