1. A method for selective identification of biometric data for efficient compression, the method comprising:

  • (a) determining, by an evaluation module operating on a biometric device, if a set of biometric data acquired from a subject satisfies a quality threshold indicating sufficiency of quality for subsequent automatic or manual biometric recognition, while satisfying a set of predefined criteria that includes criteria for achieving efficient compression of a corresponding type of biometric data, which includes estimating an expected amount of compression artifacts that data compression would introduce to the set of biometric data, accessing a table that relates amounts of compression artifacts introduced in biometric data to predetermined threshold levels for biometric recognition, and comparing the expected amount with a corresponding threshold level indicated by the table for the biometric recognition, the determination including the estimation, the access and the comparison performed prior to performing data compression on the set of acquired biometric data; and

    (b) classifying, based on the determination, whether to retain the set of acquired biometric data for subsequent data compression.
