COMPARATIVE ANALYSIS OF VARIOUS VIDEO WATERMARKING TECHNIQUES

The embedding of a digital signature, or tag data is carried out in the frequency domain. The high frequency varieties are chosen by any LH and HL in the wavelet domain which are to be applicable in DCT. Coefficients are changed mid-frequency DCT coefficients such transactions by a low frequency of the watermark to be embedded. Watermark can be recovered from the video by selecting a random watermark of any reference framework. The proposed techniques are more secure, robust and are efficient due to the use of static DCT. Watermark techniques uses a bands HL and LH for adding watermark where the movement does not impact the quality the extracted watermark until if the video displays for different types of malware attacks. In this work we have taken three video watermarking techniques i.e. BIT GET (spatial), DWT, DCT and one video formats ie.MPEG video to perform a comparative analysis of different techniques using single video formats, to obtain the best performing technique for video watermarking. Such that to increase robustness of the video and decrease the embedding time.
