Abstract

This paper presents a new technique of secret sharing in fuzzy vault system with use of multi-level steganography. Every hidden information on each level is linked with individual key used in embedding and revealing stages. Higher level secret is a share which is needed to reconstruct concealed data. It is possible that different shares contain various amount of information, what means that some of them may be more or less privileged. As a result, the secret can be decoded correctly in a number of ways. Therefore the main objective of this paper is to propose a system in which some users may hide additional shared secret in an inconspicuous manner.
