Hiding Data in VQ-compressed Images Using Dissimilar Pairs

by Chih-yang Lin, Chin-chen Chang
"... Abstract. Steganography is the art and science of embedding secret data in another medium to prevent the leakage of secret information. A VQ-based (vector quantization) steganographic method usually involves changes of the block values in the VQ images, which might cause serious distortion. As a res ..."

Reversible data hiding

by Zhicheng Ni, Yun-qing Shi, Nirwan Ansari, Wei Su - IEEE Trans. Circuits Syst. Video Technol , 2006
"... Abstract—A novel reversible data hiding algorithm, which can recover the original image without any distortion from the marked image after the hidden data have been extracted, is presented in this paper. This algorithm utilizes the zero or the minimum points of the histogram of an image and slightly ..."

A Survey on Reversible Data Hiding in Encrypted Image

by Princy Raj, Sreekumar K
"... Abstract — Recently more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original image cover can be losslessly recovered after data embedded is extracted while protecting the image content’s as confidential. In this survey pa ..."

A Lossy Compression Tolerant Data Hiding Method Based on JPEG and VQ 171 A Lossy Compression Tolerant Data Hiding Method Based on JPEG and VQ

by Ren-junn Hwang, Timothy K. Shih, Chuan-ho Kao
"... A lossy compression tolerant data hiding method is proposed in this paper. The image which hides data is named a stego-image. Most of data hiding methods will lose some hidden data when the stego-image is compressed by lossy compression process. However, there are few people will transmit image with ..."

A Survey on Separable Reversible Data Hiding in Encrypted Images

by Mithu Varghese, Teenu S Jhon
"... Data security and data integrity are the two challenging areas for research. So many research is progressing on the field like internet security. The requirement of secure transmission of data is important in our life. The transmission should be more secure when channel/network is too noisy/fraudule ..."

Hiding Secret Data in an Image Using Codeword Imitation

by unknown authors
"... Abstract—This paper proposes a novel reversible data hiding scheme based on a Vector Quantization (VQ) codebook. The proposed scheme uses the principle component analysis (PCA) algorithm to sort the codebook and to find two similar codewords of an image block. According to the secret to be embedded ..."

Reversible Data Hiding in Encrypted Images

by Prajakta Jagtap , Atharva Joshi , Shamsundar Vyas
"... Abstract: The following paper proposes a novel scheme of data hiding in encrypted images based on lossless compression of encrypted data. In encryption phase, the original content is encrypted into images. As majority of the encrypted data is kept unchanged, the quality of the decrypted image is sa ..."
