Abstract

This study presents a two principles, Cryptography and Steganography, each tow methods work separately from the other to ensure a secure content. We are developed an algorithm to increase the safety and reliability of the copyrights of the images or books (etc.) that published on the internet by providing a watermark image (as logo) hiding inside the original file that we want product it. Firstly reading image (the logo image), convert it to binary and encrypted it by using EX-OR with a secret key and embedding it inside a gray image in the LSB (in the 1^st) and hiding first key in the 2^nd bit and the second key in the 3^rd bit, then we embedding them in the LSB of Original image in RGB to be protected. The two secret keys, first one as an encryption key and the second key using as signature (data) that have been taken from the cover image (original) to make sure the reliability of the image transmitted via the Internet.

Keywords:

Cryptography, EX-OR, gray code , LSB , steganography , watermark,
