A Novel Approach for Cheating Prevention Through Visual Cryptographic Analysis

Confidentiality is probably the most common aspect of information security and the authors need to protect their valuable information and it has become an inseparable issue as information technology is ruling the world now. Cryptography is the study of integer mathematical techniques related aspects of Information Security such as confidentiality, data security, entity authentication and data origin authentication but it is not the only means of providing information security, rather one of the techniques. In this paper, a more secure scheme is given to solve the cheating problem without extra burdens by adopting multiple distinct secret images. Moreover, for sharing these secret images simultaneously, the share construction method of visual cryptography is redesigned and extended by generic algorithms.
