Efficient Searching Strategy for Secret Image Sharing with Meaningful Shadows
Chin‐Chen Chang, Ngoc-Tu Huynh, Ting-Feng Chung · International Journal of Machine Learning and Computing · 2014
In this paper, we propose a new visual secret sharing scheme which is suitable for grayscale images.The proposed scheme achieves the following objectives.First, it satisfies four general criteria of visual secret sharing systems: security, accuracy, small shadow size and low computation cost.Second, the scheme can successfully reconstruct the secret image exactly.Finally, the decoding cost of our proposed scheme is much less than that required by other previously proposed schemes.Therefore, our proposed scheme is suitable for real-time applications.
