In some applications, it might be useful or necessary to tie a cryptographic key or a random number to a particular individual, either through a 'user Identifier' (userID) or information that may be used to identify the individual such as a person's biometric data. These data can be the user's fingerprints, hand geometry, iris pattern, or any other suitable biometric identification. Here we make the key or random number generation process dependent on user-specific data, such as a userID or biometric data. A userID-based or biometric-based key or random number generated based on our algorithms may be used in asymmetric-key cryptographic systems (such as the RSA) or the symmetric-key cryptographic systems (such as the DES).
