digital watermarking of satellite images by LSB and DWT methods

Description : Watermarking is a special technique used in present day communication, for copyright protection. It is very essential in case of communicating through multiple networks i.e., internet. In this project we are providing an authentication tool for image/picture communication using specialized methods named least substitution bit (LSB) and discrete wavelet transform (DWT).In this satellite image is used as watermark which increases the height of robustness. Using DWT we embedded the watermark image into to the cover image and secret information is included inside it. So, a hacker should not capable of reading the hidden information .Hence we find more secure communication.
