WebVisual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used. The technique was proposed by Naor and Shamir in 1994. WebFeb 2, 2024 · Step 1: An input image will be selected. It must be an RGB image. Step 2: Red, Green and blue Channels are separated from an input Image. Step 3: Each Channel is then further encrypted into 8 shares. This encryption will depend on key used. Step 4: From Step 3, we get 24 shares, it means each channel has 8 shares each.
