Joint Secret Sharing and Data Hiding for Block Truncation Coding Compressed Image Transmission

摘要

This study proposed a scheme that incorporates secret sharing and data hiding techniques for block truncation coding compressed image transmission. The bitmap of each compressed block is encrypted and meanwhile two quantization levels are hidden in two share images. The secure transmission system still preserves the properties such as low complexity and acceptable reconstruction image quality of the standard block truncation coding compression. In addition, each share image is half size of the compressed version such that no extra burden is laid on available transmission resources Experimental results demonstrate the effectiveness of our scheme.
