Abstract: The present disclosure provides a system for media path security includes an authoring system having a content stream transform and corrupter for corrupting content data and providing decorrupting data, a media container for conveying the corrupted content data and decorrupting data, and a client system having a fix-up component for fixing the corrupted content data in dependence upon the decorrupting data. A client system is also provided as having an input for receiving a media container and a fix-up component for fixing the corrupted content data in dependence upon the decorrupting data.

Abstract: A method and system for secure data protection is provided. The method and system includes carrying out a transform on structured data comprising a fixed data field for implementing an application, the structured data having n segments, each having m bits, including: encoding each of the n segments subsequently to provide n coded segments, including: encoding each of the (n?1) segments depending on a previous segment value; and changing at least one of the n encodings to the n segments such that the fixed data field of a first structured data is encoded differently from the fixed data field of a second structured data, and the transformed first structure data and the transformed second structure data are further processed in the same operation for implementing the application.
