Fingerprint hashing is merging fingerprint recognition and cryptographic methods. The aim is to perform a recognition using fingerprint while, at the same time, hiding the private information related to the fingerprint, thus enabling public fingerprint templates.


Keeping a database in a safe place is not easy. Even with good encryption methods and special care, databases containing sensitive information, such as bank account numbers, are vulnerable to being compromised. Nobody wants something like that to happen when dealing with fingerprint identification.

Security of a fingerprint-based system can be divided into two main areas:
  1. 1.

    The electronic security, which poses the question: “Is the electronic system, at the other end of the wires, a real trustful authorized fingerprint system?”

  2. 2.

    The liveness security, w ...
