    Abstract: A reservation changing system provides diverse services. A memory card 200 obtains, via a mobile telephone 400, a distance from a present location to a boarding station for a train for which a reservation has been made, and judges whether to perform a train reservation change search depending on the relationship between the obtained distance and a time remaining until a departure time of the train. When it is judged that a reservation change search is to be performed, the memory card 200 obtains an expected arrival time at the station from a timetable server apparatus 500, compares the obtained expected arrival time with the departure time, and when a time margin between the two times is insufficient, the memory card 200 instructs a reservation center apparatus 300, via the mobile telephone 400, to change the reservation, and receives and stores reservation information.

    Abstract: Disclosed is a group admission system (1) having a client (200e-200g) and a server (100a-100d) that belongs to a closed group within which contents are available. The client (200e-200g) determines whether it is permissible to request to join the group to be a member device thereof based on the number of groups that the client (200e-200g) is permitted to be in. If permissible, the client (200e-200g) transmits a registration request to the server (100a-100d) with information unique to the client (200e-200g). The server (100a-100d) determines whether to permit the client (200e-200g) to join the group by registering with the server (100a-100d) based on the number of member devices registered with the server (100a-100d) and the maximum number of member devices registerable with the server (100a-100d). If it is permitted, the server (100a-100d) registers the unique information, and transmits group identification information to the client (200e-200g). The client receives and stores the group identification information.

    Abstract: An information security apparatus that manages information in a safe and reliable manner based on a complexity of an inverse operation on a set of integers that satisfy a condition. The information security apparatus comprises a private key generating unit operable to generate a private key, a parameter receiving unit operable to receive parameters which respectively determine conditions, and a public key generating unit operable to generate, with use of the private key, public keys from sets of integers that satisfy the conditions determined by the parameters.

    Abstract: A key distribution system distributes key data for using content to a second encryption device that has been legitimately outsourced processing by a first encryption device. The first encryption device acquires permission information indicating that the first encryption device has permission to use the content, generates certification information by making an irreversible alteration the to permission information, and transmits the permission information and the certification information to the second encryption device. The second encryption device receives the permission information and the certification information, sends them to a key distribution device, and acquires the key data from the key distribution device. The key distribution device receives the permission information and the certification information, judges whether or not the certification information was generated by the by the first encryption device, and if judging in the affirmative, transmits the key data to the second encryption device.

    Abstract: This invention provides a license information management apparatus and the like that do not require a tamper resistance module with a large memory even in the case where a user possesses a large amount of content. A total control unit (113) specifies a content corresponding to a reproduction instruction received from a user (S202). Further, the total control unit (113) verifies whether or not there is a LT corresponding to the specified content in a secure flash unit (120). In the case where there is the LT in the secure flash unit (120) (S203: Yes) and information concerning the reproduction of the content is received from the content decryption unit (520) (S204: Yes), an encryption/decryption unit (114) decrypts the LT stored in the secure flash unit (120) using a TRM unique key (S205). After that, the encryption/decryption unit (114) updates details of the content reproduction condition information (511a), encrypts the updated details using the TRM unique key, and writes the encrypted TRM unique key into the secure flash unit (120) (S208).
