Method and computer program product for hiding information in an indexed color image |
摘要 |
A method and computer program product for embedding information within an indexed color image such that the existence of the data is not recognizable by the human eye. The method includes the steps of altering color image data, such that it will not cause a large color change in the representing image, and hiding information using an information hiding method. The altering step is accomplished via a color set changing method. The color set changing method involves first decomposing the image in to a set of color component images, embedding data in the color component or components, which the human visual system is most sensitive to, then merging representative colors until the number of representative colors is less than or equal to the target number of colors and reformatting the resulting image into indexed color image format.
