摘要:
Embodiments of the invention provide a method for creating a source for remanufacture of encrypted content using a replicated medium. A content encrypting engine obtains a first set of meta data from a multimedia content and stores the first set of meta data in a database. A content encrypting engine obtains a second set of meta data from a signed encrypted version of the multimedia content, and stores the second set of meta data in the database. An encrypted replica duplication engine then extracts encrypted data from a first replicated medium, and combines the encrypted data with the first set of meta data and the second set of meta data. Advantageously, embodiments of the invention allow a manufacturer or replication facility to use a replica disc, which is inexpensive and abundant, as a data archive for source material.
