Abstract

We introduce a new secret sharing scheme, where the novelty lies in the use of a fixed angle segmentation technique to create circular shadow images called shares. In this way, the shares can be stacked in different angles to reveal different secret messages. The participants must be in possession of both the shares and the stacking angles, which creates the additional degree of protection.
