ABSTRACT:
A method of comparing a first representation of an identifier with a second representation of an identifier is provided. The method includes providing an expression of the first representation, such as a fingerprint, and considering the expression of the first representation against a probability distribution based on the variation in the expression between different example representations of the second representations, to provide a first consideration. The method also provided for considering the expression of the first representations against a probability distribution based on the variation in the expression between different population representations, to provide a second consideration. By using the first consideration and second consideration together it is possible to provide a measure of comparison between the first representation and the second representation.
