Secret sharing is a scheme used to distribute secret among a group of users.
Rather than making duplicated copies of secrets among users, the secret is divided
into a number of pieces, called shares. The secret can be revealed if a certain
number of user shares are combined. The method proposed here (i)utilizes bit-level
decomposition and stacking operations to both encrypt and decrypt B-bit image,
(ii) preserves all the features of traditional (k, n) sharing schemes, (iii) allows for
perfect reconstruction of the input B-bit image, (iv) encrypts binary, gray-scale and
color images, and (v) can be effectively implemented either in software or
