In today’s scenario, uploading and downloading of digital multimedia like images, videos and audios on internet is becoming very fast in a very reasonable cost. To maintain the distribution of digital multimedia, there is a strong need for security, which is not only beneficial for the owner of the document but is also reliable for the customer.Watermarking as a tool has been implemented for the security of intellectual property rights (IPRs) of multimedia content and identifies the legitimate (or original) owner and detects malicious tampering of the video. This dissertation introduces a prototype for Smart Digital Video Watermarking based on Discrete Wavelet Transform (DWT). The algorithm can perform visible and invisible watermarking on color &grayscale video. In this scheme we have checked watermarking different environment and use the best component for that environment. So our watermarking depends on their background.

Digital watermarking is the best technique for the copyright protection to the user. To display watermarking on digital multimedia content, a watermark is embedded in digital data in such a way that it is essentially connected without connecting to the data. In the robust watermark must always remain in the watermarked video frames, even if the quality of the frames is degraded intentionally or unintentionally .Watermark is mainly used to prove the ownership of the marked work or simply used to inform users about the genuine holder’s identity or the permitted use of data. Apart from developing watermarking schemes, the selection of color scale channel is also discussed to be used to carry the watermark data. This algorithm provided more robustness and imperceptibility. The performance of the proposed algorithm was evaluated by calculating PSNR and MSE for watermarked video quality. Applications related to this algorithm corresponding to the digital video security are: Forensics and Piracy Deterrence, Copyright Protection, Content Authentication, Locating Content Online.
Result and discussion:
QualityTesting of digital watermarking- Embedding Effectiveness: The probability that an embedding algorithm will successfully embeds a watermark in a randomly selected Image. Fidelity: The perceptual quality of watermarked data. Data Payload: The degree of information that can be supply with the watermark. Blind or Informed Detection: Whether detection algorithm detect a watermark without extra information (Blind detection), or the detection algorithm requires some information related to the original version of a watermarked Image. (Informed detection).False Positive Rate: The frequency at which the watermark to be falsely detected in the Image.
The implementation of Color Video Watermarking using DWT has standard outcomes obtained which can be classified as follows: The proposed algorithm is a Non Blind Watermarking because it does not use the secret key to embed and extract the watermarked information. It is analyzed by the result obtain from the implementation of proposed algorithm that the watermarked video does not affect by the attacks of image modification. So, it is a Robust Watermarking. This algorithm can hide watermark information invisibly and embedded information still exists after video frame manipulation operation. It is an Imperceptible Watermarking.
The frame quality and similarity measurement of watermark image with compare to the original frame reflects that the frame quality and property does not affect by embedding of watermark, it has some minimal changes which cannot be judge by human eyes. The extracted information (i.e. Watermark image) can easily be read. It is proved by the experimental results of image quality and similarity measurement that the RED component is best of embedding watermark in color frame. The major obstruction is the lack of effective intellectual property protection of digital media to put off unauthorized copying and distribution. The performance of this watermarking technique defines in terms of PSNR. By observing the simulation results it shows that watermarking algorithm can work successfully for color and grayscale video sequence. After application of different attacks quality of watermarked video frame is unchanged so system is imperceptible and robust against common video processing attacks.
