Implementation of Embedding and Extracting Watermarking

Abstract

In this paper, we used an image with a gray scale (256 bits) and bmp type. An image can be converted into binary file by using one of filters (Sober, Prewitt, and Robert) to find edges of the original image. Then we input the watermark to prove the authentic and password that used as a key for ciphering the information. This information will embed by using the Vigenere system that will store the cipher information in the edge of the image. As a result invisible watermark is not noticeable to viewer and without any degrade the quality of the content. The product invisible watermark is robust against distortions processes and resistant to intentional tampering solely intended to remove the watermark. Only the person who know the password and watermark and the cipher system, can read the information, we use a visual basic 6.0 program to implement this work.
