An automatic vehicle dispatching system includes automatic vehicles, and a server device that performs communication with the automatic vehicles. The server device includes: a storage that stores: area information that includes path points in a predetermined area that indicate a drive route, each of the path points including driving attributes that represent an automatic vehicle movement state on the drive route; and vehicle information indicating a vehicle attribute of each of the automatic vehicles; and a route searcher that generates, for each of the automatic vehicles, first route information that includes path points selected from among the path points of the area information according to the vehicle information that corresponds to the automatic vehicle, the first route information indicating a first drive route for the automatic vehicle. Each of the automatic vehicles is controlled to drive based on the first route information generated.

Automatic vehicle dispatching system and server device

The data exchange processing apparatus pertaining to the present invention includes a cryptographic engine unit performing cryptographic processing and verification processing, a stream control unit outputting content while performing cryptographic processing of the content using the cryptographic engine unit, an unauthorized device list update unit verifying an unauthorized device list using the cryptographic engine unit, and a state management unit outputting a permission notification to the unauthorized device list update unit when detecting a low load section of the content according to metadata of the content and processing position of the stream control unit, the low load section being a section in which processing load on the cryptographic engine unit is lower than in other sections. The unauthorized device list update unit, when receiving the permission notification from the state management unit, causes the cryptographic engine unit to execute verification processing of the unauthorized device list.

Data exchange processing apparatus and data exchange processing method

To provide a device that easily judges that content that has been edited and moved back differs from original content. A content transmission devicedivides edited content composed of partial original content and partial edited content to generate transfer data pieces, generates a nonce value of each piece, encrypts the piece based on the nonce value, and transmits the encrypted transfer data pieces and nonce values. When switch occurs between the partial contents, the devicegenerates nonce value such that discontinuity exists between the generated nonce value and immediately previously generated nonce value. A content reception devicereceives the encrypted transfer data pieces and nonce values, decrypts the pieces based on the nonce values, writes the transfer data pieces into recording medium. When discontinuity exists between currently received nonce value and immediately previously received nonce value, the devicedetects reception of partial edited content.

Content transmission/reception system

Provided is a content transmission devicethat can reduce failure of content key confirmation processing during special playback such as fast-forwarding and fast-rewinding. A key management unitgenerates or updates a key parameter, and stores therein the generated or updated key parameter. The key management unitreceives a key parameter from the content reception device, and calculates a difference between the key parameter stored therein and the received key parameter. By using the calculated difference, a transmission control unitjudges whether or not to change a transmission speed at which an encrypted content portion is to be transmitted, and depending on a result of the judgment, selects one of transmission speeds and transmits the encrypted content portion in accordance with the selected transmission speed. When the difference is greater than a first threshold value, the transmission control unitselects one of the transmission speeds that is slower than a current transmission speed.
