TAILIEUCHUNG - Effect of noise on hidden data

This paper simulates an effective data hiding technique . steganography based on LSB insertion and RSA encryption in order to provide seven million times better security than the previous work. The Main idea of proposed scheme is to encrypt secret data by RSA 1024 algorithm, convert it in to binary sequence bit and then embedded into each cover pixels by modifying the least significant bits (LSBs) of cover pixels. The result image is also known as steganography image. | ISSN:2249-5789 Garima Tomar et al, International Journal of Computer Science & Communication Networks,Vol 2(1), 12-15 Effect of Noise on hidden data Garima Tomar Faculty of Electrical and Electronics,MITS Ujjain garimatomar@ Abstract -This paper simulates an effective data hiding technique . steganography based on LSB insertion and RSA encryption in order to provide seven million times better security than the previous work. The Main idea of proposed scheme is to encrypt secret data by RSA 1024 algorithm, convert it in to binary sequence bit and then embedded into each cover pixels by modifying the least significant bits (LSBs) of cover pixels. The result image is also known as steganography image. The PSNR value of this steganography image is db. In this paper Baboon image is used for experimental steganography image is transmitted through AWGN channel, and performance is simulated. The image and hidden data are reconstructed with the SNR level ≥9 dB. Key words: Steganography, LSB, RSA algorithm, AWGN channel image, so that it almost becomes impossible for the attacker to discover any embedded message. There are many techniques for encrypting data [5], which vary in their security, robustness, performance and so on. Also, there are many ways for embedding a message into another one. The most popular one is embedding a message into a gray image using LSB [6]. In this method the data is being hidden in the least significant bit of each pixel in the cover image. After hiding data in image the form of image is called stego image. In this paper LSB insertion method is used for embedding data in cover image ,resulting stego image is transmitted through AWGN channel and performance is simulated. I INTRODUCTION On internet the amount of digital images has increased rapidly but security of images becomes increasingly important for many applications, like, confidential transmission, military and medical applications. In steganography, .
