Image secret sharing with identification of cheaters

Abstract

This paper is an extension of (t, n) threshold secret sharing scheme based on Matrix Projection. The proposed scheme achieves publicly verifiable image secret sharing with identification of cheaters. The added functionality uses asymmetric key algorithm to identify the cheaters. The scheme can identify up to n number of cheaters. The experimental results show that proposed scheme is accurate, secure and with small size of shares than the original secret image.
