Abstract:
1. An image processing method for subjecting electronic image data to predetermined image processing, the method comprising: inputting electronic image data to be processed; decomposing the input electronic image data into n types of colors and producing m pieces of color decomposition data for each color, wherein both m and n are integers; producing palette data in which each of the m pieces of color decomposition data is assigned a palette identification number; producing palette exchange data for exchanging the palette data, wherein the palette exchange data is produced by performing a pseudo random number creating processing in which one of a common key, a public key and an arbitrary number input by a user is an initial value; exchanging palette identification numbers of the color decomposition data based on the produced palette exchange data; and synthesizing the m pieces of color decomposition data whose palette identification numbers are exchanged, encoding the synthesized data, and outputting the encoded data as a piece of scrambled image data.
