1.1 WATERMARKING BASICS
the internet have shield difficulties of the digital information. Hence, safety of undisclosed messages through transmission develops a hard issue. Digital watermarking has given that safety of digital information or finding information in contradiction of illegal misuses and sharing. Watermarking is a technology that assures and marks likely data certification, safety and copyright protection of the info. The purpose of watermarking is to contain secreted data in multimedia info to guarantee safety examination. It would be then possible to develop the enclosed info, even if the info was inaccurate by one or extra non-dangerous spasms. In this paper, we present the numerous kinds of watermarking methods and application section where watermarking method is compulsory. Furthermore a study on the some different effort is prepared in image watermarking area.
The simple model of Digital Image Watermarking contains two parts: 1. Watermark embedding 2. Watermark extraction The first technique is Watermark Embedding that is obtainable in Figure 1 and the second technique is the Watermark Removal that is obtainable in Figure 2.
Key Words: Quantum watermarking, Pseudo Random sequence, DCT-DWT and DWT-DCT Algorithm
1. INTRODUCTION
Fig -1: Watermarking Introducing approach
Security of digital info has become a widespread matter due to the rapid growth of the universal multimedia technology. Copyright safety of digital info has developed an important problem over growing usage of internet. Digital watermarking is that tools that delivers safety, data authentication and copyright safety of the digital info. Digital watermarking is the procedure of inserting secret digital info, signal hooked on the digital media such as image, video, acoustic and text. Later the implanted info is identified and removed out to disclose the actual identity of the digital media. Watermarking is used for Evidence of Rights, Copying Hang-up, data verification, Data Hiding and Recording Monitoring. Digital Image Watermarking technology has numerous uses for safety of digital info, warranty, supply of the digital media and label of the user info. Watermarking of data has developed a very significant area in info hiding. This paper explores the key technologies of Digital Image Watermarking and explores its applications and approaches for the safety sides.

Watermark Embedding is the method of implanting watermark into the unique image. The yield is the Watermarked image. This procedure is passed out at source’s side. Watermark Removal is the Procedure of identifying watermark from the Watermarked image.
1.2 PROPERTIES OF WATERMARKING The basic necessities of the digital watermarking can be treated as qualities, properties. Different uses require singular properties of watermarking. The different attributes of the watermarking yield different place in application
