High Imperceptible Encoding for Computer Networks Security

Today, computer and network technologies provide easy-to-use communication channels for steganography. In most algorithm used to secure information both steganography and cryptography are used together to secure a part of information. Steganography has many technical challenges such as high hiding capacity and imperceptibility. Digital Steganography exploits the use of a host data to hide a piece of information in such a way that it is imperceptible to a human observer. Wavelet transforms that map integers to integers allow perfect reconstruction of the original image. Hence, the authors proposed an algorithm that embeds the message bit-stream into the LSB's of the integer wavelet coefficients of a true-color image.
