This research paper proposes a hybrid combination of semi-fragile Singular Value Decomposition (SVD) accompanied by Binocular Notification Difference (BND) for stereoscopic image watermarking pattern. The proposed model originated with two basic segments. At initial stage the logical intrinsic algebraic properties is used to generate content dependent watermarking through Mersenne Twister Algorithm. Once the generation of watermarking content, the BND scheme is directing the watermark embedding process. The BND inherits the tradeoff between total watermark content with clarity on visual acuity. The anticipated approach enriched through dual authentication method by chaotic map method to ensure credibility on security. Consequently the projected hybrid model is equated with other models in experimental results and analysis. This model is ensures the optimal performance against other methods in terms of tamper detection with authentication.
