Security Enhancements for High Quality Image Transaction with Hybrid Image Steganography Algorithm

Abstract

Steganography is technique of hiding a secret (coded) message within an ordinary message.The purpose of steganography is to keep the information under covers while both the sender and the receiver share the information. Steganography and cryptography are firmly related, cryptography scatters the message so that it cannot be understood while steganography hides the existence of the message. The seed values are using in such manner that the IMAGE QUALITY which is measured in terms of PSNR increases and Within the image the data remains safe. The process goes on as; a pseudo-random number generator first generate a sequence of random numbers by an arbitrary seed. Then the cover image is splited into dynamic-size blocks. A route is created by using this sequence and in the LSB of the pixels,the secreat data s embedded along this route. In this research work, implemented the frequency domain technique using Discrete Wavelet Transformation and perform classification to find the LSB’s from the input image using DNN technique. It performs the encryption using ECC algorithm to enhance the security factor. After that, the encryption algorithm using classifies the secure information in the imaging system. To evaluate the performance parameters like Peak signal to noise ratio and Structure Similarity Index Measure and Decryption time factor to achieve this output and compare the existing algorithm using Association Neural Network.
