摘要: In traditional visual cryptographic methods, a reconstructed secret image is usually at a binary gray level and is expanded in size, and the created shadow images often appear meaningless and noise-like. This paper will provide a meaningful shadow based multiple gray level visual cryptography without size expansion (MSML) method. This method not only creates a reconstructed secret image with multiple-gray levels and without size expansion, but the created shadow images also appear similar to the cover images specified by the user. Moreover, a user can adjust the qualities of the reconstructed secret image and the shadow images according to his requirements.
