Visual cryptography system proposed a image encryption and decryption method. In the proposed
method Red, Green, Blue color images using visual cryptography. In existing system is working for
share created, it is encrypted separately by using visual secret share creation (VSS) algorithms. The
proposed work is original images share1 and ahare2 created XOR-Based visual cryptography. This
proposed schemes share1 encryption and share2 encryption included in RSA algorithm. The share1
and ahare2 decryption process is enable secret image sharing and then stacking. The proposed
system is value calculate the PSNR and MSE formula and then image security using NPCR and UACI
formula. The color image encryption and decryption using RSA algorithm and matlab coding.
