| 20090141889 | DATA PROCESSING APPARATUS - To improve encryption technology for a data processing apparatus in order to reduce a possibility of having communication broken by a third party. The data processing apparatus encrypts subject data and renders it as encrypted data to record it on a predetermined recording medium, and decrypts the encrypted data recorded on the recording medium to change it back to the subject data. The encryption is performed in units of plain text cut data generated by cutting the subject data by a predetermined number of bits, where the number of bits of the plain text cut data is varied and dummy data of a size having the number of bits matching with a piece of the plain text cut data of the largest number of bits is mixed with pieces of the plain text cut data other than that of the largest number of bits out of the plain text cut data. | 06-04-2009 |
| 20090154693 | ENCRYPTION PROCESSING APPARATUS, ENCRYPTION METHOD, DECRYPTION PROCESSING APPARATUS, DECRYPTION METHOD AND DATA STRUCTURE - To allow encryption by setting conditions of decryption variously. Encrypted data obtained by encrypting subject data has header data | 06-18-2009 |
| 20090304183 | COMMUNICATION SYSTEM AND COMMUNICATION METHOD - To improve a communication system including two communication apparatuses so as to reduce a possibility of having communication decrypted by a third party. The communication system includes a first communication apparatus and a second communication apparatus, where one of the communication apparatuses encrypts transmission subject data and transmits generated encrypted data to the other communication apparatus which decrypts received encrypted data. Each of the communication apparatuses generates an algorithm used for encryption each time it performs the encryption or decryption. In this case, each of the communication apparatuses generates the algorithm by assigning past solutions to a solution generating algorithm capable of having the past solutions assigned thereto and thereby generating a new algorithm. The past solutions are erased when they are no longer used. | 12-10-2009 |
| 20100061550 | DATA PROCESSING APPARATUS - To improve a technology of encryption for a data processing apparatus in order to reduce a possibility of having communication broken by a third party. The data processing apparatus encrypts subject data to render it as encrypted data and records it on a predetermined recording medium, and also decrypts the encrypted data recorded on the recording medium to change it back to the subject data. When performing the encryption, an algorithm and a key to be used for the encryption are generated by using solutions which are sequentially generated by assigning past solutions to a solution generating algorithm. The solutions are erased at a stage where it is no longer necessary to assign them to the solution generating algorithm anew. | 03-11-2010 |

| 20080294717 | INFORMATION EXCHANGE METHOD, INFORMATION PROCESSOR, INFORMATION GATHERING SYSTEM, COMMUNICATION METHOD, COMMUNICATION SYSTEM, INTERMEDIARY DEVICE, AND COMMUNICATION DEVICE - The present invention relates to, for transmitting information by a server from an information gathering device to a terminal device, an information exchange method, an information processor, a communication method, a communication system, an intermediary device, and a communication device. It is directed to provide an information exchange method, an information processor, a communication method, a communication system, an intermediary device, and a communication device with which pieces of streaming video information gathered by a number of information gathering devices can be exchanged efficiently. A feature thereof lies in linking each of the terminal devices to the information gathering device that gathers a given number of pieces of streaming video information that are asked for from its linked terminal device, out of the plurality information gathering devices, directing the information gathering devices to deliver the given number of pieces of streaming video information directly to their linked terminal device, and producing and displaying, by the terminal devices, a predetermined certain screen including a given number of streaming video images that has been delivered. | 11-27-2008 |
