<p><P>PROBLEM TO BE SOLVED: To provide a system for protecting classified information, which can more securely protect from a risk such as the leak of classified information including personal identification information or the like. <P>SOLUTION: This system is constituted such that, when it decides that a third hash value D3a acquired from fingerprint data D3 inputted from a fingerprint input device F matches any of first hash values D2a stored in a classified database DB1, classified information D1a corresponding to first cipher information is read out. In addition, this system is constituted such that, when it decides that a fourth hash value D3b acquired from authentication information matches any of second hash values D2b stored in an identification information database DB2, identification information D1b corresponding to second cipher information is read out, and the classified information is outputted as classified information D1 by combining the read classified information and the identification information. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
