REGION growing VISUAL cryptography project (RIVC) MATLAB
SUMMARY
Novel Visual cryptography scheme called region increasing Visual Cryptography (RIVC), for sharing Visual secrets with multiple levels of secrecy in the same manner. In the diagram, the proposed level of image content, RIVC N S is designed for multiple regions associated with secret levels, and is encoded at u + 1 shares with the following considerations: (a) each share can't get any of the secrets of S (b) any T (2 p + t < 1) shares may be used to identify T-1 level of secrecy, © the number and location have not yet revealed the secrets of unknown usersand (d) all the secrets in S may be disclosed when all n + 1 shares are available, and (e) secrets are recognized by Visual inspection properly folded without computing. Basic Matrix to construct the proposed level RIVC with small values of N = 2, 3, 4 are introduced, and the results of the two experiments.
