摘要：Visual Cryptography facilitates hiding a secret image into nnumber of shares distributed to n number of participants. Thiskind of scheme is very useful as the participants in such securitysystems need not know the cryptographic knowledge in order torecover the secret image from the shares. This phenomenon isknown as VCS (Visual Cryptography Scheme). An extendedVCS is the one which is capable of generating meaningful shareswhen compared with the shares of the VCS. This paper proposesconstruction of EVCS by embedding the random shares (result ofVCS) into covering images. The empirical results revealed thatthe proposed EVCS is more secure and flexible than the EVCSsfound in literature.
