Abstract: <P>PROBLEM TO BE SOLVED: To propose that data should be hidden in an image by transforming the image into the DCT domain, selecting a plurality of DCT coefficients, and embedding data into those DCT coefficients by a quantization process.  <P>SOLUTION: In the quantization process, each bit of data is stored by changing one or more DCT coefficients to a quantization value indicative of the bit of data to be stored. Alternatively, each of a set of multiple DCT coefficients are modified, such that a function of the DCT coefficients of the set is equal to a quantization value indicative of a respective bit of the data to be stored. The DCT coefficients are selected by randomly defining groups of blocks based on a secret key, and then selecting corresponding DCT coefficients from within the blocks of each group.  <P>COPYRIGHT: (C)2007,JPO&INPIT
