A system or method for enrolling a signature may include transmitting a user's public key and a time stamp to a client device. The method may further include receiving an encrypted time stamp and encrypted signature data associated with the user, wherein the signature data is encrypted using the user's public key. The encrypted time stamp may be decrypted using the user's private key, and the received encrypted signature data may be validated based on the decrypted time stamp. If the received encrypted signature data is determined to be valid, the encrypted signature data may be stored and digitally signed with the user's private key. The encrypted signature data may be further digitally certified with an administrator's private key.
