Method and apparatus for secure distribution of information recorded of fixed media

摘要

A central access control system creates distribution CDs using an embedded data encryption process. A disc ID is also encrypted and recorded on each disc of each set of distribution CDs. The central access control system records the disc IDs and a remote location access rights list (ARL). A list of unique remote location IDs are also stored. The distribution CDs are delivered to one or more remote locations equipped with an information access system that includes its unique remote location ID, a CD reader with an embedded decryption system, and a communication link to the central access control system. The information access system can send the disc ID and its unique remote location ID as an access request to the central access control system. If the access control system is able to verify and grant the request, a unique decryption key will be sent to access the particular distribution CD currently contained in the information access system. The unique remote location ID of each information access system is a public encryption key and the central access control system encrypts the distribution CD's decryption key using the requesting information access system's public key. If the central access control system is unable to verify or grant the request, an attempted security breach alert is triggered.
