  • Patent number: 8165289
    Abstract: A method is provided for deriving a single code from a biometric sample in a way which enables different samples of a user to provide the same code whilst also distinguishing between samples of different users. Different features are analysed to obtain mean and variance values, and these are used to control how the different feature values are interpreted. In addition, features are combined and a sub-set of bits of the combination is used as the code. This enables bits which are common to all user samples to be dropped as well as bits which may differ between different samples of the same user.
