摘要： PROBLEM TO BE SOLVED: To verify whether documents constituting a group are assembled online without using a visual method with respect to verification and without using a management server. SOLUTION: A device for printing paper reads a group of paper identifiers from a radio IC tag watermarked in paper constituting a group being a printing destination, generates an electronic signature of the group of paper identifiers (step 605), and prints on paper the group of the paper identifiers and the electronic signature as a two-dimensional bar-code together with a picture image (step 606, 607). A verification terminal reads the group of paper identifiers from the radio IC tag of paper and the group of paper identifiers and the electronic signature from the two-dimensional bar-code, and verifies a correspondence relation of these information from a public key certificate of a printer.

摘要： PROBLEM TO BE SOLVED: To provide a ticket processing method for generating a content key by using an IC card, and to provide a system applicable of the method. SOLUTION: A content distributor generates a content key from an identifier 1 distributed together with the content, an identifier 2 distributed independently of the content, and an identifier 3 distributed as a ticket, and enciphers the content. A ticket service provider connects the identifier 3 to an identifier (A PK ) for identifying an application which uses the content at a terminal, and distributes the ticket enciphered by a public key of the IC card to the IC card via the terminal. The IC card deciphers the ticket by a private key which the IC card holds, and generates the content key based on the identifier 3, the identifier 1, and the identifier 2.

摘要： PROBLEM TO BE SOLVED: To allow a client being a portable terminal user to use a previously used client certificate as it is even when the client changes certificate authorities because the client certificate used in a carrier A can not be used and a new client certificate sometimes has to be reissued at a carrier B when the client changes the certificate authorities (carrier) for issuing an electronic certificate, for example, the carrier A is changed to the carrier B.
SOLUTION: A self signature certificate issued by the client himself/herself is made to be a client certificate, the certificate authority issues a linkage electronic certificate that links the client certificate with a root certificate, and when an electronic signature is performed, the client has a secret key corresponding to the client certificate to generate an electronic signature. Even when certificate authorities are changed, only the root certificate and the linkage certificate are changed, and the client certificate is used as it is.
