The College of Computer Science, University of Technology discussed a Ph.D. thesis on a zero-watermarking approach for 3D videos by the postgraduate student, Ms. Dalal Thair Mahjoub.

The thesis reviewed a comprehensive, secure, and non-intrusive approach to implement zero watermarking and authenticating 3D videos by addressing the fundamental challenges associated with multimedia protection and enhancing its reliability.

The thesis relied on employing depth-aware techniques through stereoscopic contrast estimation using near-universal block matching technology, as well as enhancing the system's ability to distinguish between different characteristics even under variations in lighting, pressure, and geometric transformations, within a framework that achieves computational efficiency and execution speed.

The thesis demonstrated the proposed system's ability to adapt efficiently to spatial and temporal variables while maintaining consistent performance in dynamic 3D scenes and multiple viewing angles and fulfillment of the essential requirements for a secure, efficient, and robust zero-watermarking system for protecting 3D videos.
