摘要:
The present invention provides a value information management system capable of printing electronic data (e.g. electronic receipt) representing value information while restricting the electronic receipt to one of printed form and unprinted form so as to prevent fraudulent billing. A secure memory card 13 securely stores therein a payment-related electronic receipt, a printer 14 prints the electronic receipt, and deletes the electronic receipt from the secure memory card 13 after completion of the printing, and transmits a receipt ID identifying the electronic receipt to a receipt management server 17, so that the receipt management server 17 can manage the electronic receipt identified by the receipt ID as being printed out.

To provide a content usage management device capable of correctly determining limitation-on-usage information about contents, such as an expiration date. A memory card 2 has a storage section 22 for storing coupon data 221 and expiration date data 222 as information about contents, and a processing section 21 for performing processing pertaining to the contents. When information about the time of the portable terminal 1 has been changed, card control means 212 of the processing section 21 detects a change-of-time event; acquires the current time of the portable terminal 1 achieved before and after the change of time, by way of data communications means 211; and updates the expiration date data 222 stored in the memory card 2 in accordance with the time information. When the expiration date of the coupon is determined, the expiration date data 222 stored in the memory card 2 are compared with the current time of the portable terminal 1, to thus determine whether or not the coupon is valid.

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.

A content reproduction system that allow the user to rent or purchase any desired contents for reproduction without depending on a predetermined type of information of the user. The content reproduction system includes: a recording medium storing a license ticket including an encrypted master key; and a reproduction apparatus that receives from the user a request for a selected content and the information of the selected content, acquires distribution content information corresponding to the selected content, stores it in association with the license ticket into the recording medium. When reproducing the content, the reproduction apparatus generates a content using an encrypted content decryption key and an encrypted content that are contained in the distribution content information, and using a master decryption key information corresponding to the distribution content information, and reproduces the generated content.

A content playback apparatus prevents related content recorded on separate media that make up a virtual package from being played separately, thereby restricting playback of the content to only when the virtual package is assembled as intended by the creator, and protecting copyright of the content. A key obtaining unit obtains a second key, with use of key management information recorded on a recording medium on which related content relating to the encrypted content is also recorded. An information obtaining unit obtains the encrypted content and key generation information that relates to generation of the first key, from a source other than the recording medium. A key generation unit generates the first key with use of the second key and the obtained key generation information. A decryption unit decrypts the encrypted content with use of the first key.

With an object of disclosing various techniques for both usage and protection of content, the present invention has an object of providing a playback control apparatus, a position judgment apparatus, and a playback control system that permit playback of content only in one area. In other to achieve the object, with the present invention, when a user passes through an automated ticket barrier to enter a station, the automated ticket barrier transmits, to a memory card via the mobile telephone, a playback key for playing content. When the user passes through an automated ticket barrier to leave a station, the automated ticket barrier instructs the memory card, via the mobile telephone, to delete the playback key, and the memory card deletes the playback key.
摘要:
A useful ticket management system is provided, which can perform adjustment using a ticket to which non-updatable value information is assigned together with an electronic value, according to a payment form. The ticket management system includes an IC tag attached to a money ticket, a money ticket management server, and a mobile terminal. The IC tag holds a money ticket ID for identifying the money ticket, and reads the money ticket ID. The money ticket management server includes a storage unit, receives the money ticket ID from the mobile terminal, and writes a valid money ticket ID to the storage unit. The mobile terminal includes a storage unit, acquires the money ticket ID held in the IC tag, transmits the acquired money ticket ID to the money ticket management server, and writes amount information of the money ticket identified by the valid money ticket ID to the storage unit.
摘要:
To provide a contents linkage information delivery system for use by a content provider to deliver contents in a manner that a user is allowed to acquire, according to a user request, a content that relates to another content. The present invention is directed to a contents linkage information delivery system for delivering a related content that is associated with another content. The contents linkage information delivery system is composed of a first playback apparatus for playing back the other content, a server for transmitting the related content, and a second playback apparatus for playing back the related content. The first playback apparatus, the server, and the second playback apparatus mutually communicate via a communications channel. The first playback apparatus includes a playback position information acquisition unit for acquiring time-base playback position information of the other content, a request input unit for receiving a user request, and a first transmission unit for transmitting the time-base playback position information. The server includes a first reception unit for receiving the time-base playback position information transmitted from the first playback apparatus, a related content acquisition unit for acquiring the related content based on the time-base playback position information, and a second transmission unit for transmitting the related content. The second playback apparatus includes a second reception unit for receiving the related content transmitted from the server, and a first output unit for outputting the related content.
