Image Scrambling Algorithm Based on Chaos Theory and Sorting Transformation
This paper proposed a novel image scrambling scheme based on chaos theory and the sorting transformation. The new algorithm calculates the permuting address codes by sorting the chaotic sequence, not like common method by quantizing the chaotic sequence. Therefore, the new scheme does not require knowing the probability density function of the chaotic orbits in advance, thus not only facilitati...
متن کاملA Digital Watermarking Algorithm for Color Image Based on DWT
An efficient digital watermark embedding algorithm for color image was presented in this paper, which is based on the discrete wavelet transform (DWT) and the spectral characteristics of human vision system. Firstly, three color separations was performed for color image, and color components of color image were transformed by DWT. Secondly, the embedding position of the watermark was confirmed ...
متن کاملEfficient Digital Encryption Algorithm Based on Matrix Scrambling Technique
This paper puts forward a safe mechanism of data transmission to tackle the security problem of information which is transmitted in Internet. We propose a new technique on matrix scrambling which is based on random function, shifting and reversing techniques of circular queue. We give statistical analysis, sequence random analysis, and sensitivity analysis to plaintext and key on the proposed s...
متن کاملDigital Image Scrambling Algorithm Based on Chaotic Sequence and Decomposition and Recombination of Pixel Values
Based on chaotic sequence and decomposition and recombination of pixel values, a new digital image scrambling algorithm is proposed in the paper. While scrambling image pixel values, this new algorithm is able to change the spatial position of pixel, simultaneously scrambling both position and pixel values. Experiments show that the new algorithm is larger in key space, highly efficient, sensit...
متن کاملChaotic Image Scrambling Algorithm Based on S-DES
With the security requirement improvement of the image on the network, some typical image encryption methods can’t meet the demands of encryption, such as Arnold cat map and Hilbert transformation. S-DES system can encrypt the input binary flow of image, but the fixed system structure and few keys will still bring some risks. However, the sensitivity of initial value that Logistic chaotic map c...
