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

Analisis Steganography Terhadap Keamanan Data
TL;DR: The computer security system includes security data this time able to issue demand, and steganography is the art of concealing the existence of information within seemingly innocuous carriers.

Flash memory for ubiquitous hardware security functions
TL;DR: It is demonstrated that unmodified commercial Flash memory can provide three important security functions: true random number generation, digital fingerprinting and information hiding, and all schemes require no change to Flash chips or interfaces, and do not require additional hardware.

On the Implementation of a Fragile Medical Image Watermarking Technique Using Saliency and Phase Congruency
TL;DR: In this paper , the saliency and phase congruency methodologies are applied on the original medical image to highlight the object features and a mask is generated which segregates the area of interest from the portions containing visual medical information.

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.
