| 20080229106 | Information processing apparatus and data transmission method of information processing apparatus - An apparatus stores first divided trust information which is one portion resulting from division of trust information generated by a transmission target apparatus that is a transmission target for data, receives a transmission request for the data from the target apparatus and receives second divided trust information which is the other portion resulting from division of the trust information of the target apparatus and verification information generated using information indicating a state of the target apparatus that made the request, recovers the trust information using the first divided trust information stored and the received second divided trust information, verifies trustworthiness of the target apparatus using the recovered trust information and the received verification information, transmits the data indicated by the request to the target apparatus when the verification of trustworthiness is successful. | 09-18-2008 |
| 20080282316 | Information processing apparatus, program and method for transmitting content in security scheme according to license policy - An information processing apparatus is connectable to a user device over a network. The apparatus includes a processor. The processor transmits, in response to reception of a request for a particular item of content, an identification of a security scheme which is applicable to transmission of the particular item of content in accordance with a license policy. When the item of content can be received by the user device in the security scheme, the processor transmits the item of content in the security scheme. | 11-13-2008 |
| 20100023580 | CONTENT DELIVERY APPARATUS, COMMUNICATION SYSTEM, CONTENT DELIVERY METHOD, AND COMPUTER PRODUCT - A content delivery apparatus and method operable to access a network, to which a content management apparatus and a content acquiring apparatus are connected, where the content delivery apparatus accepts content delivery request(s). The content delivery apparatus obtains a number of content delivery apparatus(es) having the same content on the network, and a number of times that the content management apparatus has accepted inquiries regarding content holding status(es) from content acquiring apparatuses, and calculates a delivery priority by dividing a number of requests by the number of content holding apparatuses. The content delivery apparatus, when the delivery request accepting section accepts the delivery requests for a plurality of contents, delivers the plurality of contents preferentially from a content having a high delivery priority. | 01-28-2010 |
| 20100023594 | CONTENT PROCESSING APPARATUS, CONTENT PROCESSING METHOD, AND RECORDING MEDIUM - A content processing apparatus includes an extracting part extracting undownloaded contents from a list of downloadable contents, a providing situation storage part that stores a providing situation of the contents that content processing apparatus provided to other apparatuses, a priority order determining part determining the priority order of download in the extracted undownloaded contents based on the providing situation stored in the providing situation storage part, and a downloading part downloading the contents in accordance with the priority order determined by the priority order determining part. | 01-28-2010 |
| 20100023815 | MANAGING APPARATUS, MANAGING METHOD, MANAGING SYSTEM AND COMPUTER PRODUCT - An apparatus accepts an injustice (grievance) report containing injustice report source terminal information for identifying a terminal device transmitting the injustice report and injustice content holding terminal information identifying a terminal device holding the content altered from the original content and content identification information for identifying the content; accesses a correspondence relation recording unit recording, in association with content identification information identifying the content, notification destination terminal information identifying a terminal device to which the content holding terminal information is notified, and content holding terminal information notified to the notified terminal device; determines that the injustice report accepted by the injustice report accepting is false and discards the false injustice report, when the injustice report source terminal information contained in the injustice report is not coincident with the notification destination terminal information recorded in the correspondence relation recording unit. | 01-28-2010 |
| 20100082795 | INFORMATION PROCESSOR, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD AND COMPUTER PRODUCT - An information processor is connectable to a communication system containing a plurality of terminal devices. The information processor receives content holding terminal information for identifying a terminal device holding a content, calculates a content holding terminal number corresponding to the number of terminal devices holding the content on the basis of the received content holding terminal information, holds a determination reference serving as a reference for determining whether the content holding terminal number is below a predetermined threshold value, determines on the basis of the content holding terminal number calculated by the terminal number calculator and the determination reference whether the content holding terminal number concerned is below the predetermined threshold value, and transmits an extinction preventing instruction for making the terminal device holding the content concerned execute processing of preventing extinction of the content when determining that the content holding terminal number is below the predetermined threshold value. | 04-01-2010 |
| 20100124230 | TERMINAL APPARATUS AND PROGRAM - An apparatus transmits reservation information including a contents-ID identifying the contents and a terminal-ID identifying the apparatus that transmits the reservation information to the apparatus determined by the contents-ID, receives the reservation information transmitted from the apparatus that accepts the reservation operation and updates a reservation terminal list that associates the contents-ID and the terminal-ID, verifies whether the acquired contents have defects, transmits a search-request having the contents-ID identifying the contents judged that have defects to the apparatus determined by the contents-ID, receives the search-request transmitted from the apparatus judged that have defects, retrieves the terminal-ID registered in association with the contents-ID of the search-request from the reservation terminal list, transmits a search-result having the acquired terminal-ID, receives a search-result from the apparatus to which the search-request is transmitted, and acquires recovery data of the contents that have defects from the apparatus identified by the terminal-ID of the search-result. | 05-20-2010 |
| 20100180316 | BROADCAST DEVICE, RECEIVER, AND BROADCAST METHOD - A broadcast method includes specifying an information holding device which holds recorder information for identifying a recorder that receives and records broadcast contents, attaching device information for identifying the information holding device specified by the specifying, to the broadcast contents, and broadcasting the broadcast contents to which the device information is attached. | 07-15-2010 |
| 20100251035 | PROGRAM, INFORMATION PROCESSING DEVICE, CONTENT PROCESSING METHOD, AND CONTENT PROCESSING SYSTEM - An information processing device includes: a receiving operation for receiving, from a transmission device, content and first verification data corresponding to divided content obtained by dividing the content; a detecting operation for detecting an error of the divided content based on second verification data to be calculated based on the divided content and the first verification data received in the receiving operation; and an obtaining operation for obtaining other divided content corresponding to the divided content having the error detected in the detecting operation from another information processing device different from the transmission device, when the error of the divided content is detected in the detecting operation. | 09-30-2010 |
