摘要： An optical disc recorder/reproducer, a personal computer, a television receiver, an IRD and so forth are connected mutually via a 1394 serial bus. When data transmitted from the personal computer to the optical disc recorder/reproducer via the 1394 serial bus are to be recorded, an isochronous packet is sent to the recorder/reproducer inclusive of the data to indicate whether the personal computer is a device capable of cognizing copy control information. And depending on whether the source of the transmitted data is a copy control information cognizant device or not, the optical disc recorder/reproducer updates the copy control information with reference to a selected table, and then the updated copy control information is recorded on the optical disc. This system can distinguish between a prerecorded disc and a user-recorded disc, hence achieving exact management of copy control information.

摘要： The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is not open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

摘要： A method and system for transferring information using an encryption mode indicator (EMI). The present invention provides several secure information communication modes in which data (e.g., representing an audio/visual work) can be transmitted from a source device to a sink device (receiving station) in a number of secure modes. In one secure mode, EMI mode A, the information of the transmission is not allowed to be copied as a whole work; this is the highest level of copy protection. In second secure mode, EMI mode B, the information of the transmission is allowed to be copied once and once only by the sink device. In a third transmission mode, no encryption is used and free copying is available. Depending on which secure mode is selected between mode A and mode B, a different encryption process is used by the source device to encrypt the transmission. Further, depending on which secure mode is selected between mode A and mode B, a different decryption process is used by the sink device to decrypt the transmission. The present invention is particularly useful for transmissions between a source device and a bit stream recorder which does not have the capability to extract certain encryption information from a packet header. By using different encryption processes for each transmission mode, an unauthorized device placed between the source and the sink devices that alters the EMI code will be unable to thereafter render or record the audio/visual work because the decryption process selected will differ from the encryption process used.

摘要： A security module is provided in a data recording medium, data to be written to the data recording medium is encrypted with an content key different from one data to another, and the content key is safely stored in the security module. Also, the security module makes a mutual authentication using the public-key encryption technology with a drive unit to check that the counterpart is an authorized (licensed) unit, and then gives the content key to the counterpart, thereby preventing data from being leaked to any illegal (unlicensed) unit. Thus, it is possible to prevent copyrighted data such as movie, music, etc. from being copied illegally (against the wish of the copyrighter of the data).

摘要： An information recording/playback device stores beforehand, on a recording medium, secret information in which a writing/reading method thereof cannot be analyzed and which can be read only by a special reading method. The secret information is applied to a key for content encryption or decryption when performing recording or playback of contents on the recording medium, such as music data and image data. The secret information is, for example, a stamper ID. By using the stamper ID as secret information, and a master key and a media key which are distributed in a tree-structure key-distribution system, a content-cryptosystem key is generated. Accordingly, each content is allowed to be used in only an appropriate device in which the special reading method for the secret information can be executed and to which the key is distributed by the tree-structure key-distribution system.
