Developing a Watermarking Algorithm Using Hide Information Techniques

Digital information (images, texts, audio) has become widely available on the Internet, stored and transmitted in digital form. Effective, and we can easily reproduce, retransmit and even manipulate them, This is due to the emergence of a wide range of unreliable copies and infringement of the property rights of the true owner by piracy (person/organization). The main objective of this research Watermarking techniques are applied in many tools and applications to take advantage of their properties and the solutions that provided by these techniques, and this research covers some simple techniques and algorithms and measures the effectiveness of each of them according to the basic characteristics of the watermark concept in addition to clarifying the weaknesses of these algorithms and developing a solution to reduce the weaknesses by improving the basic watermark algorithms or applying advanced techniques and concepts in this field to improve this technology by designing a system that uses the knowledge and information gained from the cover image and this process is called Side Information Techniques. This project will demonstrate theoretically and practically the benefits and effectiveness of applying Side Information technologies within the field of branding, The first important thing in this research covers the term Steganographic watermark (cover letter depends on the message in addition to concealing the presence of this message). The second important thing is to know the difference between the two types of reagents (informed) and the other (blind) And we use some techniques such as (LSB, DCT, SEW, AEW) and compare the results to choose the best technology from them.
