Abstract An efficient, computationally secure, verifiable (t , n) multi secret sharing scheme, based on YCH is p roposed for multiple 3D models. The (t, n) scheme shares the 3D secrets among n participants, such that shares less than t cannot reveal the secret. The experimental results provide suffic ient protection to 3D models. The feasibility and t he security of the proposed system are demonstrated on various 3D models. The s imulation results show that the secrets are retrieved from the shares without any loss
