Provided is a calibration device that can calculate the mounting state of a stereo camera without the placing of a physical marker. In this device, an area setting processor () preliminarily sets, for an integrated image in which a road surface image region and a setting-prohibited region are integrated, an arrangement pattern having a plurality of area setting frames, and adjusts the arrangement pattern so that the plurality of area setting frames recede from each other. An extraction processor () extracts from distance images a plurality of partial images corresponding to the plurality of area setting frames. A mounting-state calculation unit () calculates a mounting-state parameter on the basis of a plurality of partial images, such parameter relating to the mounting state of a stereo camera used to pick up stereo images.

When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the two machines, as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.

License information exchange system

A service provider (SP) receives an original license including an edit condition that shows designation of a range of a usage condition from a content provider (CP) license management server of a CP. On the basis of the received original license, a sales license generation tool of the SP generates a sales license which includes the usage condition that shows a condition for allowing the usage of the content and from which a content key has been deleted. A content key insertion processing unit of an SP license management server judges whether or not the usage condition included in the generated license information is within the range of the edit condition, and inserts the content key into the generated license information only when the usage condition is within the range of the edit condition.

Right management device, terminal device, and right management system

A unit-to-unit data exchange system preventing an unfair exchange without increasing communications cost or a load on a server. A unit () exchanges data with a unit (). An exchange completion data keeping device keeps exchange completion data that is necessary for each unit (and) to reproduce the obtained data after the data exchange is completed. The exchange completion data keeping device transmits the exchange completion data obtained from the unit () to the unit () and transmits the exchange completion data obtained from the unit () to the unit () only when the unit () and the unit (1) have successfully received data of interest.

The present invention provides a rights management terminal that can securely send and receive usage information while preventing spoofing and protecting user's privacy. The rights management terminal manages a copyright of a content using a license that includes a usage rule of the content, and includes: a first public key certificate management unit which manages, as a set, a first public key certificate that includes identification information for uniquely identifying at least one of the rights management terminal and a user using the terminal, and a first private key paired with a first public key included in the first public key certificate; a second public key certificate management unit which manages, as a set, a second public key certificate that does not include the identification information, and a second private key paired with a second public key included in the second public key certificate; a selection processing unit that selects, as a set, one of the following: the first public key certificate and the first private key; and the second public key certificate and the second private key; and an authentication processing unit that executes authentication for communicating with a server apparatus, using the public key and the private key that are selected as a set by the selection processing unit.
