摘要

Quantum computing’s rise demands new 3D image copyright solutions–this study pioneers a quantum-driven watermarking approach. Recognizing the critical role of quantum representation, we first construct a Quantum 3D Image Representation (Q3IR) model to transform digital 3D images into quantum form. Based on Q3IR, we propose a Quantum Geometry-Texture Synchronized Watermarking (QGTSW) scheme, which embeds quantum watermarks into 3D quantum images via an attack-resistant quantum coding method. This scheme integrates 3D shape features with surface textures to enable dual copyright protection for both structure and texture. We validate the feasibility by designing quantum implementation circuits and evaluate robustness under seven attack types via classical simulation of quantum processes. Results demonstrate that QGTsw extracts high-quality watermarks under diverse corruptions, effectively safeguarding 3D image copyright.
