A SECURE METHOD OF OPTIMIZED LOW COMPLEXITY VIDEO WATERMARKING

ABSTRACT In recent existence numerous video watermarking schemes have been anticipated, but the majority of them are functional to uncompressed video. At this point we propose a blind digital compressed video watermarking scheme for H.264 compressed domain to condense the number of computations.Due to its characteristics of high compressibility, it can acquire immense quality at minor bit rate, and this is the reason why many applications conform H.264 Codec. The planned method elites the macro block performing the Differential Evaluation algorithm further based on the fore determined threshold and the coefficient rarefied for watermark embedding is deployed on the parity of the coefficients after transformation and quantization. The proposed method impede the bit rate increase within a decent end point by selecting appropriate non-zero quantized AC residuals for embedding the watermark. Experimental results flaunt that there is more acceptable control towards bit rate augment and at the same time perceptual quality can be kept in existence even after undergoing different attacks
