Comparative study of various technologies gives the significant information about the PSNR, payload, quality factor and also the various attacks used in video watermarking techniques. The best techniques in various scenarios are discussed in this paper which will help the research scholars in field of video watermarking.

ANALYSIS AND DESIGN OF MULTIPLE WATERMARKING IN A VIDEO FOR AUTHENTICATION AND COPYRIGHT PROTECTION

Watermarking technique be employ instance & for a second time for validation and protection of digital data (images, video and audio files, digital repositories and libraries, web publishing). It is helpful to copyright protection and illegal copying of digital data like video frames and making digital data more robust and imperceptible. With the advent of internet, creation and delivery of digital data has grown many fold. In that Scenario has to need a technique for transferring digital data securely without changing their originality and robustness. In this paper proposed a plan of latest watermarking method which involves inserting and adding two or more digital data or pictures in a single video frame for the principle of protection and replicate the similar procedure for N no video frames for authentication of entire digital video. After that digital video is encrypted and decrypted by using motion vector bit-xor encryption and decryption technique.

Digital Video Watermarking: Issues and Challenges

International Journal of Advanced Research in Computer Engineering & Technology (IJARCET), 2018

A pilfered duplicate of a digital video would be easily disseminated to the global audience because of the rapid high-speed internet. Due to impeccably replicable nature of digital video, numerous unlawful duplicates of the original video can be made. A video can undergo several intentional attacks like frame dropping, averaging, cropping and median filtering and unintentional attacks like the addition of noise and compression which can compromise copyright information, thereby denying the authentication. Hence techniques are needed to secure copyrights of the proprietor and counteract illegal copying. One of the techniques is Video Watermarking strategy for concealing some sort of information into digital video sequences that are orders of successive still frames. In this paper, we study properties of video watermarking, the arrangement of computerized video watermarking systems, watermark attacks, its applications, issues and challenges for video watermarking. At last, we propose some future research directions.

It also provides copyright protection and authenticity to the owner of the digital objects. It helps to keep the imperceptibility of the videos. The main aim of this paper is to give the review about general concept of video watermarking which includes its types, features, applications, techniques and various attacks applied on video files to check their authentication level.

A Survey on Piracy Protection Techniques in Digital Cinema Watermarking Schemes

Recent Trends in Communication Networks [Working Title]

Watermarking is used in several areas such as CDNs (Content Delivery Networks), as part of the rights management system for counterfeit prevention. Watermarking schemes need some additional features in order to be used in digital cinema. In fact, extra watermarks are added to movies by cinema projectors in projection time, which help identify the cinema hall in which the illegal copy has been recorded. But distortions caused by hand vibrations and the point of view angle make it difficult to recover the watermark. This makes it necessary to be distortionresistant for the watermarking schemes used in digital cinema. On the other hand, theatre owners would like to locate the camcorder that has recorded the pirate copy. This requires watermarking schemes to be able to estimate the distance and angle using the distributed pirate copy. In this chapter, we present a review on watermarking techniques specifically designed to attack the aforementioned problems.

Digital Image Watermarking for Copyright Protection

IJCSIT, 2012

Digital Watermarking is the process of embedding data called watermark or signature or label or tag into a multimedia object (image or audio or video) so that the watermark can be extracted for ownership verification or authentication. A visible watermark is a secondary translucent image overlaid into the primary image and appears visible to a viewer on a careful inspection. The invisible watermark is embedded in such a way that the modifications made to the pixel value is perceptually not noticed and it can be recovered only with an appropriate decoding mechanism This paper presents an invisible image watermarking scheme for copyright protection and temper detection. The secret key encryption algorithm is used for embedding the watermark using LSB technique. The verification (the watermark extraction) process uses the same key as in encryption, and hence it can be used for copyright protection of digital media such as images, audio and video. The proposed method able to detect any modification made in the image pixels.
