Method and system for deterring electronic video piracy through image rearrangement

摘要

A method for frustrating unauthorized duplication of at least a portion of a sequence of images being embodied in digital data in a given order in a bitstream, the method including: storing data corresponding to an individual one of the plurality of images in at least one memory device in the given order; and, reading the data out from the at least one memory device in a pseudorandom order as part of the bitstream to provide a rearranged order of digital data different from the given order and adapted to frustrate conventional display of the sequence of images. A method for providing a bitstream having digital data that has been rearranged from a given order corresponding to a plurality of images so as to frustrate unauthorized reproduction of the images to a display device for receiving the digital data in the given order, the method including: storing at least a portion of the rearranged bitstream in a memory according to a pseudorandom sequence corresponding to the rearrangement; and, sequentially reading the data out from the memory in a the given order.
