Abstract

Due to phenomenal increase in the concern about security and confidentiality of information over the
internet, various techniques have been proposed. Steganography is one such technique. It’s a form of security from
obscurity. a Steganography is a technique of hiding one piece of information into another. In this paper we make
comparisons between two steganography techniques one from spatial domain (LSB) and other from frequency domain
(DWT) on the basis of various attacks. No doubt LSB provides high PSNR and good image quality but it’s not so robust
to attacks. Full retrieval of data is not possible after attacks. On the other hand DWT is more robust to attacks.
