Comparative Study of Wavelets for Image Compression with Embedded Zerotree Algorithm,tion of image compression. The EZW is specially designed algorithm which uses zero tree property of wavelet transformed image to arrange the coefficients. These coefficients gives the progressively improved image information in order to pre-determined threshold. We have used Haar, Daubechies, Bi-ort

,DCT-Based Gray Image  Watermarking Scheme,secured digital data transfer. There exist several techniques for digital image watermarking to provide the security but standardization has not been done yet. In this paper, a DCT-based robust digital image watermarking scheme has been proposed. The scheme selects each block for DCT randomly. The s

Five-Input Majority Gate Design with Single Electron Nano-Device, gates are important part of the decision-making circuits based on voting. Being one of the nano-electronics devices single electron devices reduces the size of the complete circuit. The function of the five-input majority gate is tested by simulating the proposed circuit in SIMON simulator and anal

Extended Directional IPVO for Reversible Data Hiding Scheme,imum value modification and smallest, second smallest, and so on for minimum value modification. The data embedding capacity has been improved than previous data hiding schemes while keeping visual quality unaltered. Experimental results are compared with existing state-of-the-art methods and achiev

Random generation of numeric and image OTP, distribution of encrypted image OTP and formation of final numeric OTP using digit repositioning scheme impose a great security to the system.
