Method and system for deterring electronic video piracy through image rearrangement

Abstract

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.

What is claimed is:  
     
         1 . 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, said method comprising: 
 storing a portion of said data corresponding to an individual one of said plurality of images in at least one memory device in said given order; and,    reading said stored data out from said at least one memory device in a pseudorandom order as part of a bitstream to provide a rearranged order of digital data different from said given order and adapted to frustrate conventional display of said sequence of images.    
     
     
         2 . 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 said images to a display device for receiving said digital data in said given order, said method comprising: 
 storing at least a portion of said rearranged bitstream in a memory according to a pseudorandom sequence corresponding to said rearrangement; and,    sequentially reading said data out from said memory in said given order.
