Abstract: A video disc designed for providing security and tracking data in the rental video media market. Those new formats for video players and media allow for inclusion of security features which both allow tracking of rental of such media and prevent unauthorized rental thereof Each player includes a decision circuit which plays a particular optical disc only if a player identification number recorded on a special separate magnetic track on the optical disk is the same as the player identification stored in the player, and if a movie identification number optically read from the disc matches a movie identification number recorded on the special separate magnetic track. A corresponding apparatus is provided at the video rental store which, at the time of rental, records on a magnetic portion of the media in encrypted form the movie identification number and the number of the particular disc player for which that rental is intended. The authorization encryption uses the private key of a public key system, the public key and the modulus being pre-recorded on the optical portion of the disc.

Abstract: Un sistema para proporcionar datos de rastreo y seguridad para medios de video de renta, entre los que se incluyen discos digitales de video y casetes digitales de video. Los nuevos formatos de las reproductoras de video y medios permiten la inclusion de características de seguridad que permiten el rastreo de la renta de esos medios y, a la vez, evitan la renta no autorizada de los mismos. Cada reproductora incluye un circuito de decision que reproduce un disco particular ( o cinta) solamente si el numero de identificacion de la reproductora, que está grabado en una tarjeta de memoria de autorizacion, separada, especial, es idéntico al numero de identificacion de la reproductora grabado en la misma, y si un numero de identificacion de película que se lee opticamente a partir del disco coincide con el numero de identificacion de película grabado en la tarjeta especial. Se proporciona un aparato correspondiente en el establecimiento de renta de video con el que, al momento de rentar el video, se graba en la tarjeta de autorizacion, en forma cifrada, el numero de identificacion y el numero de la reproductora de discos en particular para la cual está destinada la renta. El cifrado utiliza una clave especial de un sistema publico de claves, la clave publica y el modulo se graban previamente en la porcion optica del disco.
