20100281522 | ACCESS RIGHT MANAGING SYSTEM, ACCESS RIGHT MANAGING METHOD, AND ACCESS RIGHT MANAGING PROGRAM - An authentication device includes a user authentication certificate generation unit that issues to another device user authentication information on which information about a user is recorded; and a right transfer certificate/token generation unit that issues right transfer information and a token corresponding to the right transfer information to another device on the basis of information about a user to whom the right is transferred and a condition under which the right is transferred. A service proxy access device includes a token request unit that requests the issuing of the right transfer information and the token in order to access another device; and a user proxy access unit that accesses another service using the token. The service providing device includes a user authentication certificate request unit that acquires user authentication information from the authentication device using the token. | 11-04-2010 |
20100316218 | PERSONAL INFORMATION MANAGING DEVICE FOR FALSIFICATION PREVENTION OF PERSONAL INFORMATION AND NON REPUDIATION OF PERSONAL INFORMATION CIRCULATION - Falsification and repudiation of personal information ransmitted/received for circulation cannot be prevented when there is no trusted third party. A personal information managing device issues a personal information registration certificate corresponding 1:1 to personal information and sends the certificate to a service providing device through a user terminal. When personal information is transmitted/received, the user terminal and the service providing device check the relationship between the certificate and the personal information, thus the user terminal and the personal information receiving device can confirm whether or not the personal information has been falsified. When the personal information is transmitted/received, the personal information is always encrypted. After the encrypted personal information is transmitted/received, the decryption key is transmitted/received. By using the transmission/reception of the decryption key between the personal information managing device and the service providing device as a personal information reception confirmation message, repudiation of personal information transmission/reception can be prevented. | 12-16-2010 |
20100319061 | PERSONAL INFORMATION MANAGING DEVICE, SERVICE PROVIDING DEVICE, PROGRAM, PERSONAL INFORMATION MANAGING METHOD, CHECKING METHOD AND PERSONAL INFORMATION CHECKING SYSTEM FOR FALSIFICATION PREVENTION OF PERSONAL INFORMATION AND NON REPUDIATION OF PERSONAL INFORMATION CIRCULATION - A personal information managing device issues a personal information registration certificate corresponding to personal information one to one and sends the issued personal information registration certificate to a service providing device through a user terminal. The user terminal checks the personal information registration certificate, so that the user terminal confirms that the personal information managing device has not falsified the personal information. Further, when personal information is transmitted/received, the user terminal and the service providing device check the relationship between the personal information registration certificate and the personal information, so that the service providing device confirms that the personal information managing device has not falsified personal information. Moreover, when sending personal information, the personal information managing device attaches its signature, so that the personal information managing device confirms that the service providing device has not falsified the personal information. | 12-16-2010 |
20110004753 | CERTIFICATE GENERATING/DISTRIBUTING SYSTEM,CERTIFICATE GENERATING/DISTRIBUTING METHOD AND CERTIFICATE GENERATING/DISTRIBUTING PROGRAM - In a certificate generating/distributing system, an authentication apparatus includes token transmitting means transmitting, to a service mediating apparatus, a certificate generation request token, which is information corresponding to a first certificate valid in the service mediating apparatus, together with the first certificate. The service mediating apparatus includes mediating apparatus token forwarding means forwarding the certificate generation request token to a service providing apparatus. The service providing apparatus includes certificate requesting means transmitting the certificate generation request token to the authentication apparatus when requesting a second certificate valid in the service providing apparatus. The authentication apparatus includes certificate transmitting means transmitting, to the service providing apparatus , the second certificate generated based on the first certificate in response to the request of the second certificate by the certificate requesting means. | 01-06-2011 |
20110289552 | INFORMATION MANAGEMENT SYSTEM - An information providing device which provides information, a privilege policy providing device which stores a privilege policy setting whether or not information is allowed to be provided and provides the privilege policy, and an authentication device, are provided. The authentication device includes a privilege information management means for storing privilege information indicating whether or not the privilege policy is allowed be provided by the privilege policy providing device, and a privilege certificate issuance means for issuing a privilege policy certificate including a content of the privilege information. The information providing device includes a privilege policy acquisition means for requesting the privilege policy providing device for the privilege policy based on the privilege policy certificate and acquiring the privilege policy, and an information providing means for providing stored information to another device based on the acquired privilege policy. The privilege policy providing device includes a privilege policy providing means for providing the privilege policy to the information providing device based on the privilege policy certificate. | 11-24-2011 |
