Abstract
Security in the recent technology world is an important issue to be taken care of and to be encountered with preventive measure on various aspects. Secret sharing is a technique used in visual cryptography (VC) which divides the image into many shares and by overlapping those shares original image is revealed, but it creates a threat when an intruder get shares with which the image is going to be decrypted easily. However, in the present project work, an extremely useful bitwise operation is performed on every pixel with the help of key. The key is provided by new concept of sterilization algorithm. Initially, Red, Green, and Blue channels get separated from image and are going to be encrypted on multiple levels using multiple shares; it converts an image into unreadable format and by combining all the shares in proper sequence the original secret image is revealed.
