Recursive Information Hiding in Visual Cryptography

Sandeep Katta

Abstract: Visual Cryptography is a secret sharing scheme that uses the human visual system to perform computations. This paper presents a recursive hiding scheme for 3 out of 5 secret sharing. The idea used is to hide smaller secrets in the shares of a larger secret without an expansion in the size of the latter.

Category / Keywords: applications / visual cryptography, secret sharing, recursive hiding of secrets, information efficiency, 3 out of 5 secret sharing.
