Analysis of Visible and Invisible Image Watermarking – A Review

As the digital data is transferred over the internet which may harm the digital data like tampering of data etc. Therefore the need of digital data protection has been increased with the advancement in the technology. Watermarking is a technique used to protect the digital data. Digital watermarking is a technique by using which user can get the copyright of its product which prevents the data from tampering. Many techniques are available for video watermarking like Discrete Wavelet Transform, Least Significant Bit Technique etc. [2].The properties of digital watermarking are for copy control, In fingerprinting, For identification of ownership, For Authentication, Monitoring of digital video broadcast, In video tagging etc. [1]. The techniques of video watermarking that have been introduced till date are studied and comparison between all of them is made out to find the best efficient technique. The analysis of the results is done and the implementation is done using the MATLAB software
