Patent attributes
Systems, methods and apparatuses are disclosed for protecting encoded media data. A minimum set of information needed to encode a single message for an encoded audio signal is loaded separately from the media data into an encoder. A media license file is generated to protect the encoded data, where the underlying information relevant to the media data may be hidden through encryption or other means in order to foster security. The algorithm(s) for encoding may be provided using a shared library, combined with an encoding payload that provides the minimum information set required to form the single message. A partial decoder may apply pattern matching information in the encoded payload in order to confirm that the encoding is actually present and is proper. Accordingly, the payload must be successfully decoded and verified before the underlying data may be decoded.
