    摘要: A configuration is achieved in which content copying between media and content downloading are performed effectively and under strict management. In content copying between media, the identification information (medium ID) of a copying destination medium is obtained using an API for providing a predefined processing, then the obtained medium ID is transmitted to a server to obtain copying permission information from the server, and then content copying is performed under the management of the server. This configuration allows a copying destination medium to be managed, which can eliminate the unauthorized use of the content. Also, the configuration in which content downloading from the server is performed according to, for example, a Java® program allows a ROM disc on which the content is recorded to store the program and to be provided to a user.

    摘要: To provide an apparatus, a recording medium and a method for effectively preventing unauthorized use of a content. A content containing broken data different from correct content member data is recorded on an information recording medium. Furthermore, transform data, as the correct member data, to be substituted for the broken data, and a fix-up table storing setting position information of the content are recorded on the information recording medium. During the content playback process, the transform data is substituted for the content member data in accordance with the fix-up table recorded on the information recording medium. With this arrangement, even if the encryption key corresponding to the encrypted content recorded on the information recording medium is leaked, an apparatus unable to acquire the transform data cannot play back the content. Unauthorized use of the content is thus controlled.

    摘要: An information processing apparatus, an information recording medium, an information processing method, and a computer program are provided.In an information recording medium storing many pieces of content, a configuration that allows use management on segmented content basis is provided. A plurality of content management units corresponding to title, index and other information are set by partitioning stored content in an information recording medium. Different unit keys that are encryption keys are allocated to different content management units. At least the content real data included in each content management unit is encrypted by use of the unit key and the encrypted data is stored. In content reproduction, units are identified and decryption is executed by use of a unit key corresponding to each unit for reproduction. In an information recording medium storing many pieces of content for example, each of segmented pieces of content may be managed.
