Abstract

A unique type of cryptographic method called "visual cryptography" allows for decryption to be carried out using only the human eye. Generally speaking, for some crucial security, in modern society, processing and protecting information from attacks is becoming a very important aspect for people. Researchers are developing new ways to protect information from unwanted intrusion. Numerous encryption methods have been discovered, with many more yet to be discovered. Visual ciphers originated from certain encryption methods that used images to hide information. The visual cryptography technique is employed, for instance, to distinguish between a machine and a human; similar to how scanning and printing, captcha, and other applications use visual cryptography techniques. As a result, researchers created numerous strategies and methodologies for visual cryptography systems. The purpose of this research is to investigate different visual cryptography systems and to analyze their performance in terms of pixel expansion, the quantity of hidden images, image format, and the type of share generated. We will also provide a succinct explanation of the rules for additional research.
