Significant Data Hiding through Discrete Wavelet Transformation Approach

The methods of communication of invisible information have become need in the today's digital era. The network connectivity and high speed devices made easy passing massive data instantly. As boom of the huge data transmission has taken place due to easy use of the technology, the protection of the data has become prime issue. Steganography hides messages inside some other digital media. Cryptography, on the other hand obscures the content of the message. We proposed a novel integration of an incorporating text and image steganography to find a solution for improve security and protect data. The proposed methods shows a high level of efficiency and robustness by combining text and image which involves the scheme of discrete wavelet transformation combining text and image by secretly embeds encrypted secrete message text data (cipher text) or text image in the content of a digital image. A comparative study of the different techniques has been illustrated by computing Mean square error (MSE) and Peak Signal to Noise Ratio (PSNR).
