摘要： Methods and apparatus for protecting copyrighted information, e.g., video signals, from unauthorized use are described. Encrypted video signals are transmitted from a source device, e.g., display adapter, to a display device, e.g., monitor, over analog signal lines after the identity of the destination device is confirmed by receipt of a certificate assigned to the destination device. A session key, used for encrypting the analog signals, is generated and exchanged between the source and destination devices. The source and destination devices each include a pseudo-random number generator driven by the session key. As part of the encryption process a false video signal is generated. The false video signal and R, G, B video signals are transmitted to the display device over four lines. The lines used to transmit the R, G, B and false video signals are periodically swapped as a function of the output of the pseudo random number generator to encrypt, e.g., scramble, the video signals. To avoid having to provide an additional line between the display adapter and the display device beyond those used in conventional displays, horizontal synchronization information is combined with, e.g., modulated on, one or more of the other signals transmitted to the display. The horizontal sync line is then used to convey one of the four video signals. The display device extracts the horizontal timing information from the received video signals and decrypts the signals using the output of its pseudo random number generator to reverse the scrambling process used to encrypt the transmitted video signals.

摘要： Methods and apparatus for protecting copyrighted information, e.g., video signals, from unauthorized copying. Analog red (R), green (G) and blue (B) video signals are transmitted from a source device, e.g., a display adapter, to a display device, e.g., a monitor, over corresponding analog signal lines after the identify of the destination device is confirmed by receipt of a certificate assigned to the destination device. A session key, used for encrypting the analog signals, is generated and exchanged between the source and destination devices after the identification of the destination device is confirmed. The source and destination devices each includes a pseudo-random number generator driven by the session key. The lines that carry the R, G and B video signals are changed, e.g., swapped, on a periodic basis as a function of the output of the pseudo-random number generator in the source device. The destination device, which has an input to its pseudo-random number generator synchronized with the random number generator of the source device, decrypts the received video signals in a complimentary fashion to the encryption. Encrypted digital information subject to copying constraints may be supplied to a display adapter via an IEEE 1394 compliant bus.

摘要： An electronic asset system mints a stick of electronic assets that can be spent by the user with multiple vendors. Assets sticks are issued anonymously or non-anonymously in a way without requiring dedication to a particular vendor, hence allowing the user to spend one or more assets from the stick with different vendors. The auditor randomly audit samples of the spent assets to detect whether the assets have been fraudulently used. The electronic asset system employs tamper-resistant electronic wallets constructed as dedicated hardware devices, or as devices with secure-processor architecture. The electronic asset system also facilitates handling of electronic coupons in a manner that enforces compliance between the user and the vendor. The user and vendor each maintain a stick of corresponding coupons with pointers to the most recent and oldest coupons available for expenditure. When a coupon is used or granted, the user and vendor both update the appropriate pointer to their respective sticks and then exchange signed data describing placement of the pointer to verify a correspondence between the referenced coupons.

摘要： In accordance with certain aspects, data is received from a calling program. Ciphertext that includes the data is generated, using public key encryption, in a manner that allows the data to be obtained from the ciphertext only if one or more conditions are satisfied. In accordance with another aspect, a bit string is received from a calling program. Data in the bit string is decrypted using public key decryption and returned to the calling program only if one or more conditions included in the bit string are satisfied.
