Arithmetic and Wavelet Based Information Security Using Image

Abstract

The enhancement of information technology extensively changes the communication system in society. The information is rapidly shared through the internet or other electronic message delivery system without proper security measures. The IPR (Intellectual Property Right) of digital content or digital multimedia has to face the main challenge with the fear of distortion of the contents. Steganography and Cryptography are two widely used techniques for online digital contains authentication. Here we are using both of them together to make it more powerful with the help of simple Arithmetic and Binary operations and embed the same in the frequency domain using the wavelet function. Mainly target to provide a secure text information transmission with cryptex and stegano approach with high payload. The standard metric Peak Signal to Noise Ratio (PSNR) and MSE or Mean Squared Error measures the robustness of the proposed method.
