Sudoku refers to a two-dimensional (2D) number-placement puzzle with simple constraints that there are no repeated digits in each row, each column, or each block. Motivated by this Sudoku configuration, we introduce a number of Sudoku associated matrix element representations besides the conventional representation using matrix row-column pair. Specifically, they are representations via Sudoku matrix...
This paper introduces a new method of applying the image steganography concept for image encryption. Using the PLIP (Parameterized Logarithmic Image Processing) addition [1] to embed the scrambled original image into a selected cover image, the new algorithm generates an encrypted image. Computer simulation and security analysis are given to show that the algorithm has a very large key space and can...
