The term, steganography, comes from Greek and means “covered writing”(Johnson and
Jajodia, 1998a; Petitcolas et al., 1999). The intent of steganography is to hide a message in …

Picture quality and statistical undetectability are two key issues related to steganography
techniques. In this paper, we propose a closed-loop computing framework that iteratively …

Cryptography is the science of using mathematics to encrypt and decrypt data and
Steganography is the art and science of hiding communication; a steganographic system …

The idea of this paper is to implement an efficient block-by-block singular value (SV)
decomposition digital image watermarking algorithm, which is implemented in both the …

In this paper, an adaptive steganography algorithm based on block complexity and matrix
embedding is proposed. The matrix embedding constructed by [8, 3],[8, 4][8, 5][8, 6] and [8 …

Private data in healthcare system require confidentiality protection while transmitting.
Steganography is the art of concealing data into a cover media for conveying messages …

In this paper, an adaptive matrix embedding method is proposed for grayscale images. The
2× 4 pixel block is taken as a cover unit. The local correlation of the block is used to …

In this paper, we attempt to propose a novel blind steganalysis algorithm for palette-based
images. First, the generalized difference images between adjacent pixels were constructed …

We present the design, implementation, and evaluation of the File System De-Virtualizer
(FSDV), a system that dynamically removes a layer of indirection common in modern storage …

This letter addresses the problems of conversion overflows, losses, and faults in the radix
number system. Different from the fixed length truncation conversion strategy, the proposed …
