Abstract:
A computer-readable medium containing instructions for controlling a computer system to encode data comprising:establishing a first set of data; establishing a first logo; performing a fractal transformation on said first logo to create a first set of fractal transformation coefficients; substituting at least one bit from said first set of data to a plurality of said first set of fractal transformation coefficients to form a second set of fractal transformation coefficients; and wherein said fractal transformation comprises selecting a plurality of library blocks from said first logo; dividing said first logo into a set of target blocks; comparing each target block to said plurality of library blocks to determine how well each said target block matches each of said library blocks; selecting a library block and transformation coefficients corresponding to each target block; replacing each said target block with said corresponding transformation coefficients and a reference to said corresponding library block; and writing each said corresponding transformation coefficients and said reference to said corresponding library block to memory.
