Abstract
The present invention relates to a system and a method for multi-factor authentication of communication device metadata. The system includes a communication device, and a recipient device that work together to authenticate communication device metadata using digital signatures and a user's identity through voice biometrics. User enrolls into the system by providing voice samples, from which a unique voiceprint is created and stored. For authenticating the communication device metadata with user authentication, the user issues a voice command, and the system extracts voice signatures which are compared with the stored voiceprint to verify the user's identity. Upon successful authentication, the communication device metadata is accessed, and corresponding digital signatures are generated. Further, the system authenticates the generated digital signatures and user's identity. If both are verified, the communication device metadata is considered valid and used for further processing.
