Secret sharing approaches for 3D object encryption

In this paper, we propose two secret sharing approaches for 3D models using Blakely and Thien and Lin schemes. We show that encoding 3D models using lossless data compression algorithms prior to secret sharing helps reduce share sizes and remove redundancies and patterns that possibly ease cryptanalysis. The proposed approaches provide a higher tolerance against data corruption/loss than existing 3D protection mechanisms, such as encryption. Experimental results are provided to demonstrate the secrecy and safety of the proposed schemes. The feasibility of the proposed algorithms is demonstrated on various 3D models.

► A geometric framework for 3D secret sharing is proposed in this paper. ► We propose two secret sharing approaches for 3D models using Blakely and Thien and Lin schemes. ► The proposed approaches provide a higher tolerance against data corruption/loss than existing 3D protection mechanisms. ► To increase the security of the proposed schemes, we used two lossless data compression algorithms Huffman Coding and ZLIB prior to splitting the 3D models.
