Visual cryptography is an approach for pretending the image based secrets which has the technique of computational free decoding process. The secret image is first converted into threshold based parts with random prototypes with VC. There is a possibility to change the secret image apparently with superimposing a approved subset of transparencies. The main goal of this proposed work is to monitor the various different types of data hacking on the data/information and handle them with proper type named measures. Moreover the optimization of the countering method by proposed work. This is used to broadcast the original image from source to other end(receiver) with more confidentiality. In this work , three methods proposed for enhancement of the efficiency of the VC. With the first one RGB based share with multiple slots creation in the VC with respect to ECC techniques are suggested. The result outcomes that allowed certainly that Peak Signal Noise Ratio is 58.0028 , with Mean Squared Error(MSE) outcome is 0.1164 and CC(correlation coefficient) is near to 1. With the second approach sharing creation with security scheme in VC with respect to ECC with optimized scheme for the images with color is proposed. From the results of this approach, the outcome has revealed with PSNR is 65.7307 , MSE with -.-17367 and CC is 1, the optimized PSNR value is obtained in the CS(cuckoo Search) model. With the third approach, an innovative model of VSS(Visual secret share) used to improve the efficient of VC with ECC is the proposed one. The main outcome of this approach is PSNR is 69.568 , MSE is 0.013 and the CC is 0.992 and feasible PSNR value is obtained with GWO(grey wolf optimization. This work implemented with the performance evaluation and to compare the given mentioned secured shared created models.
