As the information age is growing rapidly and data becomes highly valuable and sensitive, methods need to be discovered to protect and secure sensitive data. One such method that transfers data over network securely is Steganography. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet...............

Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message; this is in contrast to cryptography, where the existence of the message itself is not disguised, but the meaning is obscured.................

Digital Steganography exploits the use of a host data to hide a piece of information in such away that it is imperceptible to a human observer. Wavelet transforms that map integers to integers allow perfect reconstruction of the original image. Hence, we proposed an algorithm that embeds the message bitstream into the LSB's of the integer wavelet coefficients of a true-color image.............
