Abstract

In this paper, we proposed a novel reversible data hiding scheme for the compressed images for block truncation coding (BTC). In this scheme, the secret data is embedded into the compressed codes of BTC. The histogram shifting technique is employed in the proposed scheme to embed the secret data into the quantization levels of the compressed codes. After the data embedding procedure is executed, the embedded compressed codes still follow the standard format of BTC. The experimental results reveal that the proposed scheme provides good image quality of the embedded image.
