|標題:||MEANINGFUL SHADOW BASED MULTIPLE GRAY LEVEL VISUAL CRYPTOGRAPHY WITHOUT SIZE EXPANSION|
|期刊/報告no：:||International Journal of Innovative Computing Information and Control, Volume 7, Issue 3, Page(s) 1457-1465.|
|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.|
