Secret Image Sharing for General Access Structures using Random Grids
Sachin Kumar, R. K. Sharma · International Journal of Computer Applications · 2013
This paper presents a visual secret sharing (VSS) scheme for general access structures by using random grids.Compared to the existing VSS schemes for general access structures, the proposed scheme generates the shares of same size as that of the original secret image and does not require any codebook prior to encryption process.With these advantages, the proposed scheme broadens the potential applicability of random-grid based VSS.We prove that the proposed scheme gives the strong access structure.Formal proofs, security analysis and experimental results are given to demonstrate both the feasibility and the correctness of the proposed scheme.
