Video mosaic watermarking using plasma key

Video watermarking is one of the most widespread techniques amongst many presently are used; this because extreme existences copyright abuse and misappropriation occur for video content. In paper, a new algorithm proposed to embed logo in digital protection. To make watermarks more robust attack, host frame embedding indices must be changeable. A determined frames by plasma function, Host location also another function. Logo divided using mosaic principle, size blocks initially according degree protection, whenever small, it leads safe embedding, vice versa. Digital embedded easily without any degradation quality, other side, watermarked retrieved applying reverse extracted watermark still recognizable. The experimental results confirm that against three types attacks which addition Gaussian noise, JPEG compression, rotation process.
