Key-dependent 3D model hashing for authentication using heat kernel signature
We model 3D model-based hashing with robustness, uniqueness, security, and spaciousness. Our algorithm is a key parameter-dependent hash function. Multi-scale HKS vectors are used for the feature vector of the intermediate hash. Parameter refinement further improves the robustness, uniqueness, and spaciousness. Security analysis shows the high differential entropy of our hash.
