Utilizing the RGB Color Model and Halftone Technique for Color Segregation in Visual Cryptography
Sk Asfaq Ahamed, Indranil Sarkar, MD Altabuddin Molla, Sandip Roy, Rajesh Bose
Abstract: When the right key image is utilised, a specific encryption method called visual cryptography can be used to conceal information in images so that it can be decoded by the human eye. This experiment describes a halftone-based, covert visual cryptography system for colour graphics. A colour picture is first divided in to three monochrome picture with red, green, && blue tones. Second, using the halftone approach, these three images are converted to binary images. Finally, the sharing images are obtained using the conventional binary secret sharing approach. This plan offers a more effective technique to conceal natural photographs in various ways. Furthermore, the size of the shares remains constant regardless of how many colours are visible in the hidden image.
