Lee and Huang proposed a dual-image reversible data hiding method to protect the
confidential data in 2011. The image quality obtained by the method is good because each …

The reversible information hiding technique is to embed secret information in multi-media.
Through extraction algorithm, the concealed information can be extracted and the original …

The stego-images generated by many existing hiding techniques are not economic in size,
and hence need compression. Unfortunately, compression usually destroys the secret …

This paper presents an improved method of the reversible data hiding for JPEG images
proposed by Xuan, et al. The conventional method embeds data into the JPEG quantized 8 …

Objective of this paper is to improve the security for multimedia files and to increase the
volume of hidden data in an image. The technique of reversible data hiding is capable of …

Reversible data hiding, in which the stego-media can be reversed to the original cover
media exactly, has attracted increasing interests from the data hiding community. Recently …

A reversible data hiding method is widely used in medical application and military

such as image, audio, or text with a minimum amount of perceivable degradation to the …

This paper proposes a reversible data hiding scheme for BTC-compressed images. A block
in the BTC-compressed image consists of a larger block-mean pixel and a smaller block …

Recently, Hwang et al.(HKC) proposed a simple improvement reversible data hiding
scheme based on the histogram shift. They claim that the read don't send any additional …
