Cryptographic Modes of Operation

Block ciphers are cryptographic algorithms that encrypt fixed-size blocks of data A cryptographic mode of operation for a block cipher describes the different ways that cryptographic algorithm may transform data to achieve sufficient complexity that offer protection against attacks. This…

Fingerprint Recognition

Fingerprint recognition needs to steps: Fingerprint registration Fingerprint authentication During fingerprint registration, the fingerprint image(s) are converted into what is called Fingerprints Minutiae Data (FMD). FMD is saved into the database, not the fingerprint image itself. During fingerprint authentication, fingerprint…
