Abstract
Aspects of the present invention relate to machines, systems, and methods for using a zero knowledge hash function to verify validity of an ID. Certain configurations may provide machines, systems, and method for proving the ID is genuine, the information on the ID is correct, and the user presenting the ID is the same as the user in the ID. Some configurations may store a hash based on a one-way function of a data string created from information on the ID in a hashed data string database. Certain variations of the invention may query the database to verify the hashed data string exists in the database. Based on the response of the database to the query, a card authenticator may be configured to send a control transmission to an access control device to cause the access control device change from a first state to a second state.
