The Mechanism of Secure Watermarking based on Encryption and Attached Frame with Image

Abstract

Watermarking is the common techniques that have been used in information security. It’s the way of hiding data or information within images in order to protect ownership and copyrights. Nowadays, many companies and enterprise apply watermarking to their products. With the increment and distribution of personal photos and photographs images around the world, the protection of ownership and copyrights becomes inevitable. Many algorithms and techniques have been developed in order to embed the watermark and implement the integrity of it. The simplest one is the LSB (Least significant bits) technique.  This technique ensures that the quality of the image will not degrade but it’s prone to cropping and scaling attacks. This paper proposes and provides an algorithm that can be used for protecting watermark image from damage or stolen by embedding the watermark into the frame of image instead of image itself. The frame should be invisible so any attack processes will not be able to destroy the watermark. The result shows that the watermark is still the same under cropping and scaling processes. This could really ensure the integrity of personal photo watermarks for a large wide range.
