An electronic money system includes a plurality of electronic money terminals for withdrawing a sum of money which is spent by a user from money data which has been deposited into an information card. Utilization-history data including the number of times the information card has been utilized, and accumulated in the information card is read out at the time when data relating to the spent money is also withdrawn from the information card. Utilization-history data read out from each of the electronic money terminals are gathered and coordinated, so as to coordinate and tabulate the utilization-histories of the information card which has been utilized on any of the plurality electronic money terminals.

MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S, when a power source of the terminal apparatus is turned on first, (MTID=B) is transmitted from the terminal apparatus to a router. A transmission signal is received by the router and (HGWID=A, MTID=B) is transmitted from the router to the ISP. If (HGWID=A, MTID=B) has been registered in the database, the ISP transmits a permission message in step S. In step S, an IP address for a new terminal apparatus is allocated and the new terminal apparatus can participate in a homenetwork. If (HGWID=A, MTID=B) is not registered, a refusal message is sent to the router.

Network system

A public key certificate issuing system is disclosed which comprises a certificate authority for issuing a public key certificate for an entity, the certificate authority including a plurality of signature modules each executing a different encryption algorithm and a registration authority that receives a public key certificate issuance request from the entity.

The events experienced are stored automatically, so that the information of higher utility for a user may be taken out with responsiveness and efficiency higher than is possible with a technique of keyword retrieval over a network. An information registration unitincludes an information acquisition unit, for acquiring the empirical information, a private information adding unit, for adding the private information, a data recognition processing unit, for recognizing the acquired information, a data definition processing unit, for classifying the recognized data in accordance with the preset definitions, a data storage unitfor storage of the classified data, and a data processing unitfor generating the predictive information inferable from the empirical information and the private information. The information exploitation unitincludes an information acquisition unit, for acquiring the current state, a retrieval inputting unit, supplied with the retrieval conditions, a data recognition processing unit, for recognizing the acquired information, a retrieving unit, for extracting the information fitted to the retrieval conditions or the analogous information from the data storage unit, and an information presenting unitfor presenting the extracted information to the user.

Private information storage device and private information management device

Content data encrypted with a content key, the content key encrypted with an individual key specific to an information sending device, and the individual key encrypted with a distribution key that is updated in a predetermined cycle, and supplied are sent to an information receiving device, and the information receiving device decrypts the individual key with the distribution key, decrypts the content key with the individual key, and decrypts the content data with the content key. Thus, the information sending device does not have the distribution key, and accordingly piracy of content data can be prevented with a simple configuration. Also, the information receiving device sends the content key and a playback command to other apparatuses. Thus, other apparatuses can play back contents using the playback command and the content key. Furthermore, the information sending device decrypts the content key with the distribution key before being updated, and stores the same. Thus, contents purchased by an advance order can be actually purchased regardless of expiration dates of the distribution key. Furthermore, usage right is passed from a first information receiving device to a second information receiving device different in registration information at the tome of using contents. Thus, contents can be used among information receiving devices different from each other in registration information.

A content distribution is performed by a secure container including a content encrypted by a content key and container information set for a content transaction. The container information includes a person identification certificate identifiers list. Usage control status information including the list is generated and stored in a device during a secondary distribution among user devices after a primary distribution of the content. In the distribution among the user devices, identifying an identification certificate in reference to the list and performing a person authentication based on the identification certificate allows each of the user devices to use the transmitted content, when the authentication is affirmative.

A content distribution system allowing user authentication to be performed to identify a user in content transaction, thereby permitting the content to be used. The content is distributed with a secure container. The secure container includes the content enciphered with a content key and container information in which the content transaction condition is set. The container information includes an identification certificate identifier list. An identification certificate contains a template serving as personal identification data of a user who is to receive the content and it is identified in accordance with the list. A service provider, a user device, or the like authenticates the user in accordance with the identified certificate, and then permits the content to be used.
