摘要： A motion vector data storage device (e.g., a memory) for storing motion vector data is newly provided for reducing a quantity of reference picture data to be read from a frame memory when searching a motion vector. A forward motion vector search used for a forward prediction in a vector searching process for coding a B-picture is performed asynchronously with a coding process, and accessing to the frame memory is thereby dispersed. Data for narrowing down a motion vector search range in a P-picture can be obtained at the same time.

摘要： A multi-point conference system includes a plurality of conference terminal devices coupled to each other, image information and voice information being transmitted among the plurality of conference terminal devices so that users of the plurality of conference terminal devices are in conference with each other. A coding process unit of a transmission side conference terminal device codes image information by switching an intra-frame coding operation and an interframe coding operation and transmit coded image information when the each of the plurality of terminal devices is specified by a speaker specifying information item. The coding process unit of the transmission side conference terminal device which is specified again by a speaker identifying information item codes image information by an interframe coding operation starting from a head frame. A decoding process unit of a receiving side conference terminal device which receives the coded information from the transmission side conference terminal device decodes the coded information by the decoding operation corresponding to the interframe-coding operation using reference image information last stored in a frame memory portion corresponding to the transmission side conference terminal device.

摘要： A person authentication system capable of performing personal authentication by comparing templates that is personal identification data with sampling information input by a user is disclosed. For example, a service provider (SP) or a user device (UD) acquires the templates from a person identification certificate (IDC) generated by a personal identification certificate authority that is a third party to thereby perform personal authentication. The IDC stores data, such as a certificate identifier and a user identifier, in accordance with a format, and also stores encrypted templates in a manner that the data can be decrypted by an entity that performs authentication. This arrangement achieves efficient template retrieval and a personal authentication process, as well as effective prevention of the templates from being leaking out.

摘要： Disclosed are a person authentication system, a person authentication method, and an information processing apparatus which allow person authentication to be performed in an easy fashion in various devices by comparing a template serving as person identification data with sampling information input by a user. A service provider (SP) or user device (UD) executes person authentication by acquiring a template from a person identification certificate (IDC) generated by a third-party agency serving as a person identification certificate authority (IDA). The IDA acquires a template serving as identification data after verifying a person requesting an IDC to be issued, and generates the IDC storing template information. The IDA distributes the IDC having a digital signature of the IDA added thereto to the SP and the UD.

摘要： The present invention provides a novel configuration which allows devices capable of processing different signature algorithms to mutually verify public key certificates. In this configuration, public key certificates storing plural signatures based on different signature algorithms such as RSA and ECC are issued and each device selects a signature which can be processed (namely, verified) by itself and verifies the selected signature. Consequently, the novel configuration allows the devices each being capable of verifying only a different signature algorithm to verify the public key certificates of the other devices, so that each device can perform public key certificate verification in the cross-certification and encrypted data communication not only with the other devices having public key certificates attached with signatures based on the same signature algorithm as that of each device, but also with the other devices or providers having public key certificates attached with signatures based on different signature algorithms from that of each device, thereby significantly enhancing the reliability in communication.
