Abstract:
1. A unique code generating apparatus for generating, according to biometric information representing a physical or behavioral feature of a user, a unique code as a unique value for the biometric information, comprising: a statistic information generating module which conducts statistical analysis for a feature of biometric information for registration and generates statistic information; a statistic information table generating module which summarizes the statistic information for each biometric information, sets a unique code for each statistic information, and generates a statistic information table unique to the biometric information; a unique code extracting module which applies to the statistic information table the statistic information generated by the statistic information generating module according to biometric information for collation and extracts an associated unique code from the table; and an output processing module which outputs the unique code extracted by the unique code extracting module to an output interface, wherein the biometric information includes fingerprint information, wherein the feature of biometric information includes a direction of projected lines in a small area of a fingerprint image, wherein the feature of biometric information includes feature points including an end point or a branch point of a projected lines in a small area of a fingerprint image.
