Abstract:
A system for compressing biometric models, comprising:means for receiving and processing biometric data from a plurality of reference individuals to generate a reference biometric model for each of said plurality of reference individuals and from at least one user of said system to generate a temporary biometric model for said user; means for partitioning said plurality of reference biometric models into M subsets; means for computing a distance between said temporary biometric model and each of said reference biometric models in said M subsets and, for each of said M subsets, identifying the reference biometric model which is closest to said temporary biometric model based on said computed distances; and means for constructing a compressed biometric model for said user, wherein the compressed biometric model comprises a pattern of parameters, wherein the pattern of parameters comprises identity parameters corresponding to said closest reference models from said M subsets.
