Conclusions(VSS : A Cryptographic Technique with a lot of Fun)
Visual cryptography may not be of great practical importance in cryptography (although the idea of visual authentication schemes might be of practical value). However, visual cryptography is a great topic for teaching purposes, and for introducing cryptographic ideas to a wide audience. Besides, it’s a lot of fun!
