This paper proposes a Convex Hull Escape Perturbation (CHEP) method at Embedding Space to achieve 3D Face De-identification. For better reconstruction of the 3D faces, this paper also proposes the Spherical Bins Coloring (SBC) method to reinstate color lost in the SfS process due to change in vertices number. The top κ-accuracies of faces perturbed by CHEP drop significantly when compared to non-perturbed faces.
