Abstract - Now-a-days more people are using
photos/audio/video to record their special activities and also share them on the social media. But these may be used without permission after they are uploaded on the internet, and this is a difficult problem to overcome. An watermark needs to be added to the data. The goal of this paper is to understand various techniques proposed recently to protect the multimedia data from being illegally used. The next step in this path would be to come up with a better solution to solve this problem. The following discussed techniques are very good. A collaborative approach using few of them can be a better solution.
1.2 Classification of Digital Watermarking There are many algorithms which are being used to hide the secret in-formation. These algorithms can be categorized into two domains called: A. Spatial domain and B. Frequency domain. Spatial domain watermarking slightly modifies the pixels of one or two randomly selected subsets of an image. On the other side, in frequency domain techniques the image is first transformed to the frequency domain by the use of any transformation methods such as Fourier transform, discrete cosine transform (DCT) or discrete wavelet transform (DWT). Now the information is added to the values of its transform coefficients. After applying the inverse transform, the marked coefficients form the embedded image.

1.INTRODUCTION ( Size 11 , cambria font) As there is growing interest in developing techniques for discouraging the unauthorized duplication and misuse of digital data, the process of digital watermarking is used to prove the ownership of the data.
1.1 Watermarking "Watermarking" is the process of hiding digital information in a carrier signal; It is prominently used for tracing copyright infringements and for banknote authentication. Requirements and design of watermarking techniques are impacted by the different types of content in two major ways. This technique leaves the original data unchanged and imposes modification which can be detected using appropriate extraction algorithm. We are designing the internet portal which will help us to protect photographs, audios and videos which are used by users to prevent copyright of owner. User has to register and then login to our system for accessing copyright protection has to upload Image, Video or Audio file on server, go to Add Watermark link to add watermark into multimedia file, select Image as
