摘要

In this paper, we proposed an image authentication method based on least significant bit (LSB) hiding and double random phase encoding (DRPE) technique. An image that needs to be authenticated is first encrypted using DRPE algorithm. All amplitude information in this encrypted image is discarded and the phase mask is reserved. Then, the phase image is converted into a binary image by setting phase values less than zero as zero and other values as one. The binary image is hided in a host image with the LSB hiding approach. The recipient extracts the hiding binary image from the host image and then sets the zero-values as —it and one-values as n. Finally, the retrieved phase mask is decrypted and authenticated using DRPE and non-linear cross correlation algorithm, respectively. The proposed authentication scheme can provide another layer of security because the retrieved phase mask cannot reveal any original image information. Furthermore, the decrypted image from phase mask cannot be visually recognized with naked eyes which can distract the attention of attackers. Experimental results have shown the feasibility of the proposed authentication algorithm.
