1. An apparatus for identification of individuals comprising: visual image input means for inputting a facial image of a subject to be identified, characteristics extracting means for extracting characteristic points which represent configurations and positions of various parts of said inputted facial image, data base of individuals means for storing expressionless facial images difference detecting means for determining difference between the characteristic points of the inputted image extracted from said characteristics extracting means and the expressionless facial images stored in said data base of individuals means, and for outputting difference vector information indicative of said difference, data base of expression muscles means for storing a movement vector derived from a shifting of said characteristic points caused by a movement of expression muscles which affects the facial image of said subject, and information processing means for identifying said subject by comparing said difference vector information obtained from said difference detecting means and said movement vector information from said data base of expression muscles means, wherein said subject represented by said facial image inputted from said visual image input means is identified.
