Abstract: The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S301, and converts a format of the extracted sound track into a format compatible with a memory stick in step S302. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S304. In step S306, the CPU attaches reference information of the sound track to the file. In step S307, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.

Abstract: A technique is disclosed which makes it possible to easily control access to personal information of a user. A management server stores personal information such as a name, telephone number, address, and electronic mail address of each user. For example, if a user of a computer transmits a request command to the management server to transmit personal information of a user of a portable telephone device, the management server determines, in accordance with access restriction information, whether or not providing of the personal information of the user of the portable telephone is restricted. If the providing of the personal information requested by the user of the computer is restricted, the management server inquires of the user of the portable telephone device, who is the owner of the personal information, whether to give permission to provide the personal information. If permission is given, the management server provides the personal information to the user of the computer.

Abstract: A communication processing apparatus is disclosed which performs a process for establishing a connection upon receipt of a communication connection request. The apparatus includes a controlling element for performing a connection availability determination process upon receipt of the connection request. The controlling element performs a user identification process for identifying a user representing a connection request sender based on data in the connection request. The controlling element further carries out the process for establishing the connection if communication processing resources allocated for the user having a user identifier acquired in the user identification process are judged to be available.

Abstract: A terminal control apparatus1 for causing various terminal devices to perform appropriate operations. The terminal control apparatus comprises a communication section 11, a control section 12, and a data-storing section 13. The communication section 11 accomplishes communication with a terminal device 2. The control section 12 controls the terminal device 2. The terminal device 3 comprises a communication section 21, a control section 22, and a terminal section 23. The communication section 21 achieves communication with the terminal control apparatus 1. The control section 22 transmits terminal information to the terminal control apparatus 1. The terminal information represents the type and capacity of the terminal device 2. The terminal control apparatus 1 performs terminal control functions in accordance with the terminal information. The control section 22 controls the terminal section 23 in accordance with the terminal control functions the apparatus 1 has performed.

Abstract: This invention relates to provide a communication network system, a gateway, and a data communication method, in which the gateway has an advanced functionality. A person who issues an access request can retrieve a desired access destination easily by the following configuration: functions of routing information providing and authentication processing are added to a gateway that performs protocol conversion between two different communication networks; when an access request is issued from a public communication network such as Internet to a terminal in a local (private) communication network connected to the gateway, a request terminal is authenticated to enable prevention of unauthorized data writing and reading; and an access request user who succeeded in the authentication is provided with an active terminal list comprising accessible terminal information, or with a user condition table.
