The dealer/agent are facing the problem in management side, since they cannot find their shares visually. This happens in order to hide their secret images, at some cases noise-like random pixels can be generated using conventional visual secret sharing schemes. The stamping cover images are added using a stamping algorithm in the second phase. A solution to the pixel growth problem of the EVCS (Extended Visual Cryptography Scheme) for GASs (General Access Structure) is achieved as per the new results. And also the display quality of the recovered image is very close to that obtained image using conventional VC (Visual Cryptography) schemes. A meaningful cover image is added in each share using extended visual cryptography scheme (EVCS) to avoid this problem. Still, EVCS which was used in previous version, suffers from a pixel expansion problem. In spite of it, a codebook design for various schemes is required to the visual cryptography (VC)-based approach. Here we solve the above mentioned problem using a general approach. Binary secret images in non-computer-aided decryption environments use this approach. We are going to use two phases in the proposed approach. We construct meaningless shares using an optimization technique and the creation for conventional VC schemes based on a given access structure in the initial phase.
