Abstract
Official abstract text for this publication.
One embodiment takes the form of a method and apparatus for creating a customer-specific encryption key for encrypting digital information. The encryption key may be based on a customer number and may be associated with several devices such that the devices may encrypt and decrypt the digital information. Because each device may have the same encryption key, the encrypted data may be encrypted by a first device, transferred from the first device to a second device and decrypted and read by the second device. Thus, encrypted digital information may be shared between devices that generate a customer-specific encryption key from a common customer number. In one embodiment, the customer-specific encryption key may be utilized by a set-top box of a television system to encrypt and decrypt a digitally recorded television program.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for digitally recording a television program, the method comprising: receiving, at a first set-top box associated with a first customer via a satellite television system, an entitlement management message (EMM), wherein the EMM: includes an encrypted customer identification number that corresponds to the first customer, is received after the EMM is broadcasted to a group of set-top boxes associated with the satellite television system, is direc…
