A code converter establishes compatibility between two systems using different codes. Negabinary number system is adopted for unique applications where it provides certain definite advantages over binary number system. In this paper, we have presented VLSI implementation of a novel algorithm that can be used for the conversion of numbers from binary to negabinary number system and vice-versa. This...
This paper describes security enhancement of multimedia data using steganography. The proposed method is based on a new method of embedding ASCII text characters into moderatory bits of IEEE standard multimedia images, which are used as cover media. Simulation results for peak signal to noise ratio (PSNR) and mean square error (MSE) for text data embedding into different moderatory bit positions are...
