A system and method executed in one or more servers that interface with a Database Management System (DBMS) for signing and exchanging documents electronically with or without a PIV. If a PIV card is used, a card reader reads embedded private biometric key stored on the card and sends the private key to a node that has the corresponding public key on the X.509 certificate. The public key is derived from the private biometric key embedded in the PIV card as described above. Information contained in X.509 certificate is used to authenticate a user for example using the SSH protocol. If a PIV card is not used, the biometric data represents captured biometric data blocks, which are used to generate a biometric hash at a subscriber node. The subscriber node sends the biometric hash to a plurality of observer nodes that validate the hash by sending validation responses based on hash ledgers states at each observer node. If most of the observer nodes validate the biometric hash, the subscriber is authenticated for signing documents under any role a subscriber may have in an organization.

A device, method, and computer readable storage medium generate a biometric public key for an individual based on both the individual's biometric data and a secret, in a manner that verifiably characterizes both while tending to prevent recovery of either by anyone other than the individual. The biometric public key may be later used to authenticate a subject purporting to be the individual, using a computing facility that need not rely on a hardware root of trust. Such biometric public keys may be distributed without compromising the individual's biometric data, and may be used to provide authentication in addition to, or in lieu of, passwords or cryptographic tokens. Various use cases are disclosed, including: enrollment, authentication, establishing and using a secure communications channel, and cryptographically signing a message.

Embodiments of the invention(s) described herein enable a system that may rely on a biometric identifier entry validation system. The validation system “learns” the use pattern of a user. The validation system uses biometric methods such as facial recognition, palm veins, and thumb prints as an entry or passage token. When enough data has been collected, the validation system sends the user's biometric identifier to the use location within a bounded time frame when it expects a regular user to arrive at that location and within that time frame. In this manner the biometric identifier becomes a biometric token that replaces the need to use a form of fare media. Thus, the validation system becomes more efficient and recognizes a user faster after collecting data of a user for a short time. The validations system can record and interpret historic data. With this data, the validation system knows, on average, when to expect that passenger to arrive and where.
