A new technique for color share generation using visual cryptography
Trupti Patel, Rohit Kant Srivastava · 2016
Now a days, most of our data is travelled over internet so the security of that data is most important. Visual cryptography plays a very crucial role for security of image based secret. Visual cryptography encrypts the image in to shares and in decryption process all shares are stacked together to reveal the secret image. Here we are proposing a new scheme for color share generation. In this scheme R, G and B component is extracted from color image then apply gray share generation algorithm on R component and make n number of R gray shares then all shares are combine with B and G component to make color shares. At decryption side B and G component is extracted from all shares and then combine all r gray share to make r component and after that all R, G and B is combined to revealed the secret image. Decrypted secret image has same size as original secret image.
