PROBLEM TO BE SOLVED: To provide a signature method capable of demonstrating more safely the fact that signature has been written when a signer principal is connected to a specific connected party.;SOLUTION: The signature method comprises: a first step in which a signature server receives a site key, fingerprint data A, and a sealing key; a second step in which the signature server collates the fingerprint data A with registered information to generate a signature ID; a third step in which a portable telephone set generates sealing data from the sealing key; a fourth step in which the site server receives the site key, the signature ID, and the sealing data; a fifth step in which the site server transmits the site key and the signature ID to the signature server; a sixth step in which the signature server specifies the site key in the first step on the basis of the signature ID, collates the site key with the site key in the fourth step, and transmits the sealing key to the site server; and a seventh step in which the site server decodes the sealing data from the sealing key.;COPYRIGHT: (C)2008,JPO&INPIT
