Abstract: Music files that are downloaded from the internet are encrypted so that they are compatible with cd burning and allow music or movie files to be copied to disc a predetermined amount of time (either once or twice). Now disc burning programs only allow files (movies, music) from internet to be burned once or twice. These are the new ones that come out (disc burning programs). The old ones still operate the way they do unless running into newly encrypted files.

Abstract: A DVD terminal (20) makes a request for sending a sub-content to an authentication server (40) (in this case, attaches the “model name and serial number” of the DVD terminal (20)) (S302). The authentication server (40) generates a random number R (S304) and sends it to the DVD terminal (20) (S306). The DVD terminal (20) reads a terminal key and a terminal ID that are stored in a terminal information memory unit (25), decrypts the received random number R using a terminal key (SK_X) (S308) and sends this and the terminal ID (ID_X) to the authentication server (40) (S310). The authentication server (40) verifies the random number R and the terminal ID that are received from the DVD terminal (20) and encrypted, and judges whether the DVD terminal (20) is the authenticated terminal or not (S312).

The device then accepts data if trust is asserted during the data transfer.

Abstract: The present invention relates to a video-signal processing system, a video-signal processing apparatus and method, a recording medium, and a program for immediately recovering from loss of synchronization while encrypting/decrypting a video signal. An encryption processing unit 22 encrypts a frame number Tx, which has been obtained by counting vertical control pulses of a video signal, and transmits the frame number Tx together with an unencrypted frame number Tx and an H/V control pulse. A decryption processing unit 32 decrypts the encrypted frame number Tx so as to generate a frame number Rx and supplies the frame number Rx together with the frame number Tx and the vertical control pulses to a correcting unit 33. The correcting unit 33 generates a pseudo load pulse when the frame numbers Tx and Rx do not match with each other 16 consecutive times, and supplies the pseudo load pulse to the encryption processing unit 22 and the decryption processing unit 32.

Abstract: Copyrighted electronic media are packaged in a secure electronic format, and registered on associated registration server, which serves to provide on-line licensing and copyright management for that media. Users are connected to the server, e.g., through a computer network or the Internet, to enable data transfers and to transact licenses to utilize the media. Packaged electronic media are typically created by an author or derivative user of the work. Once the packaged media is registered on the server, the media is made available for limited use and possible license through an authorization server. This limited use is specified within the minimum permissions data set assigned to each packaged media. Without a license, users are typically permitted to view the packaged media—through a system which unpackages the media—but cannot save or otherwise transfer the media without obtaining auxiliary permissions to do so from the authorization server.

Abstract: The present invention relates to a technique for authenticating data stored on media in order to prevent piracy. According to the present invention, a lookup table contains broken or modified modulation rules comprising one or more authentication keys or components thereof, that are derived by the table's intentional breaking of standard 8-14 and 8-16 modulation rules. The authentication keys are formed and remain hidden without being transferred in the audio/video. Additionally, the lookup table is employed using conventional hardware and/or software in CD or DVD players. Each output value according to the present invention is a function of the physical characteristics of a disc that does not travel with the audio or video or graphics data. Authentication systems of the present invention optionally encompass singular, multiple or multi-level authentication systems, each of which successively must be deciphered before the audio/video is finally available.

Abstract: A user wishes to view a record, such as one that includes a person's medical history, located in a record storage area.

Abstract: Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's computer-based user station. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to have recorded for unlimited playback, for example, by a “CD burner”. An antipiracy “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”.
