A Survey of Information Hiding Schemes for Digital Images
نویسندگان
چکیده
In this survey, we first describe the purposes for image hiding. They are Steganography, Image Watermarking and Image Authentication. Classified by hiding methods, image hiding can be divided into pixel-based image hiding, frequency-based image hiding and VQ-based image hiding. In the aspect of pixel-based image hiding, we describe three representative methods, the substitution table technique, the modulus function technique, and the LSB matching revisited technique. As for frequency-based and VQ-based image hiding, we introduce methods to do Steganography, Image Watermarking and Image Authentication by applying image compression methods, JPEG and Vector Quantization.

In this paper, we propose a new algorithm in reversible data hiding, with the applications of privacy protection for digital images. Information security has long been an important topic in research and practical applications, and reversible data hiding has attracted more and more attention recently. In order to look for better performances, unlike conventional schemes, we employ the difference...
متن کاملInformation Hiding and Its Criteria for Evaluation
Within information hiding technology, digital watermarking is one of the most important technologies for copyright protection of digital content. Many digital watermarking schemes have been proposed in academia. However, these schemes are not used, because they are not practical; one reason for this is that the evaluation criteria are loosely defined. To make the evaluation more concrete and im...
متن کاملA Review of Data Hiding in Digital Images
In this paper we will overview the use of data hiding techniques in digital images. In particular we will describe how one can use Steganography to hide information in a digital image. Steganography is related to cryptography and is the basis for many of the digital watermarking techniques currently being developed. The interest in data hiding has risen with the recent activity in digital copyr...
