摘要：Arandom grid is a two-dimensional array of pixels that are either transparent or opaque. Each pixel in a random grid is produced in a totally random way. In this paper, a new algorithm is designed to carry out the encryption of the gray scale images by using random grids in such way that neither of two shares gives any especial information of original image. The original image can be recognized only when two encrypted shares are combined by XOR operation. In this approach, against others, bit planes are used instead of half toning techniques and also gray scale level will remain after decryption process in decrypted image
