摘要

PROBLEM TO BE SOLVED: To provide a biological information processing device that prevents a third party from restoring original biological information from converted biological data without reducing authentication accuracy even using the biological information in the converted biological data.;SOLUTION: The biological information processing device 1 includes: a biological information acquisition part 21 which acquires biological information of a user and generates the biological data indicating the biological information; a processing part 24 achieving a conversion function to generate converted biological data by converting at least part of a biological image using a conversion parameter determined so that the converted biological information indicated in the converted biological data obtained by converting the biological data has the same kind as the user biological information, and that the converted biological information and the user biological information do not match when collated; and a storage part 32 which stores the converted biological data as registration biological data.;COPYRIGHT: (C)2011,JPO&INPIT
