Hiding our Colors

چکیده
Several generators of graphs are developed and tested with the purpose of reening our knowledge of what makes a graph diicult to color optimally. We study the eeects of reduced variance on hardness, how much we can vary the parameterizations (i.e. n; p; k) that seem to delimit the diicult regions, and the interactions of several diierent algorithms in these diicult regions.

A survey on digital data hiding schemes: principals, algorithms, and applications
This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
متن کاملRobust Watermarking for Images Based on Color Manipulation
In this paper we present a new efficient watermarking scheme for images. The basic idea of our method is to alter the colors of the given image in a suitable but imperceptible way. This is accomplished by moving the coordinates of each color in the color opponency space. The scheme is shown to be robust against a large class of image manipulations. The robustness of the scheme is also theoretic...
متن کاملSuitability of the rgb Channels for a Pixel Manipulation in a Spatial Domain Data Hiding Techniques Authors
The aim of this research was to determine which channel in rgb color space is the most suitable (regarding perceptibility) for a pixel manipulation in a spatial domain data hiding techniques. For this purpose three custom test targets were generated. The research also shows the behavior of two closely related colors in the ps (Print-Scan) process. The results are interpreted using both a quanti...
متن کاملData Security with Image Clustering using Hopping Neighbour Technique
In this modern era, internet is widely used for the communication of information. People are easily able to exchange the information but privacy or secrecy of communicated message is an important issue. Steganography or data hiding is the process of hiding the information in such a way so that its existence is not known. The ultimate goal of this thesis is to develop the technique that provides...
متن کاملImproving Image Data Hiding Capacity Scheme using Sudoku Puzzle in Color Images
-Steganography is a skill to convey the secret data in the digital images without getting any unexpected notices to attackers. LSB replacement, the simplest method, directly replaces the secret bits with LSB bit plane. Unfortunately, it is insecure because it cannot resist against the visual attacks and statistic detection. The original work was proposed by Chang et al. in 2010, and their work ...
