Spread spectrum image steganography
TLDR
A new method of digital Steganography, entitled spread spectrum image steganography (SSIS), which hides and recovers a message of substantial length within digital imagery while maintaining the original image size and dynamic range.Abstract:
We present a new method of digital steganography, entitled spread spectrum image steganography (SSIS). Steganography, which means "covered writing" in Greek, is the science of communicating in a hidden manner. Following a discussion of steganographic communication theory and review of existing techniques, the new method, SSIS, is introduced. This system hides and recovers a message of substantial length within digital imagery while maintaining the original image size and dynamic range. The hidden message can be recovered using appropriate keys without any knowledge of the original image. Image restoration, error-control coding, and techniques similar to spread spectrum are described, and the performance of the system is illustrated. A message embedded by this method can be in the form of text, imagery, or any other digital signal. Applications for such a data-hiding scheme include in-band captioning, covert communication, image tamperproofing, authentication, embedded control, and revision tracking.read more

Fast additive noise steganalysis
TL;DR: This work reduces the computational requirements of the additive noise steganalysis presented by Harmsen and Pearlman by considering the histogram between pairs of channels in RGB images, which is shown to offer computational savings of approximately two orders of magnitude while only slightly decreasing classification accuracy.

A Steganographic Embedding Undetectable by JPEG Compatibility Steganalysis
TL;DR: In this article, a topological approach to embedding is proposed, which encodes the embedded data in the spatial domain, yet cannot be detected by their steganalysis mechanism, and can be used as a steganographic method on files stored in JPEG format.

Adaptive image steganography using contourlet transform
TL;DR: Improved version of the first adaptive image steganography methods in which it uses an advanced embedding operation to boost its security has been proposed, and has superior performance in terms of PSNR and SSIM, and is more secure against the steganalysis attack.

Error bounds for convolutional codes and an asymptotically optimum decoding algorithm
TL;DR: The upper bound is obtained for a specific probabilistic nonsequential decoding algorithm which is shown to be asymptotically optimum for rates above R_{0} and whose performance bears certain similarities to that of sequential decoding algorithms.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
