dc.description.abstractA novel blocked-based binary image authentication technique is proposed. The authentication signals of each 9x9 image block are placed in a selected 3x3 block within the 9x9 block. The authentication signal contains a certain relationship contributed by the standard deviation values of the other eight 3x3 blocks. Authentication signals are generated by rearranging the pixels in the selected 3x3 block. The rearrangement is designed according to a property of inverse halftoning to keep the visual change in the selected block imperceptible. By comparing the arrangement of the block pixels in a suspicious image with the extracted authentication signals, the fidelity and integrity of the image can be verified.en_US
