  • Publication number: 20100082982
    Abstract: In a safety determining system, an information processing apparatus performs authentication of biometrical information and gathers corresponding environment information (apparatus information, software, peripheral devices, location information). Then, the information processing apparatus sends the gathered environment information and service information of a target service to a central server. Based on the environment information, the service information, and information stored in an environment information DB, the central server determines whether it is safe to provide a service to the information processing apparatus. Based on that determination result, a service terminal provides a service to the information processing apparatus.

  • Patent number: 7660992
    Abstract: An electronic data storage system stores electronic data with attaching an electronic signature, and output the electronic data along with the attached electronic signature, which decreases the operation costs with a simple operation. By using a public key-based signature, a third party can verify the data, and by using a secret check code, the electronic signature at registration is always valid without risk of falsification. Also by attaching an electronic signature at access, the validity of the stored data is assured, and a third party can verify the data. By using all of these features, the verification by a third party becomes possible over the long term. In this way the long term storage of electronic data is implemented.

  • Publication number: 20100031327
    Abstract: Security of an information processing apparatus is ensured by performing biological information authentication and collecting the environment information about the information processing apparatus. The information processing apparatus transmits the collected environment information to a first authentication apparatus. An electronic certificate issued by a second authentication apparatus and information encrypted with a secret key issued by the second authentication apparatus are transmitted to the first authentication apparatus. The first authentication apparatus acquires the public key of the second authentication apparatus and the public key of the information processing apparatus so as to decrypt the encrypted information, and judges whether or not the decrypted information is proper. The first authentication apparatus refers to an environment information database and the transmitted information, and judges whether or not the transmitted environment information is proper.
