This paper reviews recent research on information-theoretic aspects of information hiding. Emphasis is placed on applications requiring high payload (e.g., covert communications). Information hiding may be viewed as a game between two teams (embedder/decoder vs. attacker), and optimal information-embedding and attack strategies may be developed in this

Information Hiding in the RSA Modulus
Proceedings of the 4th ACM Workshop on Information Hiding and Multimedia Security, 2016The manufacturer of an asymmetric backdoor for a public key cryptosystem manipulates the key generation process in such a way that he can extract the private key or other secret information from the user's public key by involving his own public/private key pair.

Towards objectifying information hiding
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010In this paper, the concept of object-oriented embedding (OOE) is introduced into information hiding in general and particularly to steganography which is the science that involves undetectable communication of secret data in an appropriate multimedia carrier. The proposal takes advantage of computer vision to orient the embedding process. Although, any

Reliable information bit hiding
IEEE Transactions on Circuits and Systems for Video Technology, 2002One of challenges encountered in information bit hiding is the reliability of information bit detection. This paper addresses the issue and presents an algorithm in the discrete cosing transform (DCT) domain with a communication theory approach. It embeds information bits (first) in the DC and (then in the) low-frequency AC coefficients. To extract the

Modulation and information hiding in images
1996We use concepts from communication theory to characterize information hiding schemes: the amount of information that can be hidden, its perceptibility, and its robustness to removal can be modeled using the quantities channel capacity, signal-to-noise ratio, and jamming margin.

Hiding Relevant Information in an Image
2010Data transmission is a vital issue for modern communication systems and for this security is highly required. Cryptography changes the message such that even if it is overheard by a third party, it would be unintelligible. Steganography, on the other hand, involves hiding message in such a way that the casual observer should not be able to detect the ...

Missing in action: information hiding
IEEE Software, 1996Information hiding is characterised by the idea of "secrets"-design and implementation decisions that a software developer hides from the rest of a program. It is part of the foundation of both structured and object-oriented design. In structured design, information hiding produces "black boxes"; in object-oriented design, it gives rise to the concepts

Cryptographic measures in information hiding
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008Recent information hiding schemes are scrutinized in terms of their cryptographic performance. We establish conditions under which the key equivocation function is optimal for the studied schemes, and show that, under a reasonable key generation model, the perfect secrecy property is nearly satisfied, limited by a mutual information measure that ...
