Anti-phishing based on visual cryptography and 4D hyperchaotic system

الملخص EN

A breach in cloud computing security may lead to loss, alteration, unauthorized disclosure of personal data.

In this paper we proposed authentication algorithm between client and server to secure access to user’s cloud account based on secure shares color image.

A new method proposed to distinguish human from bot with produced the secret contour which employ to generate shares in encapsulation visual cryptography.

A proposed algorithm combines between complex four dimension hyper-chaotic sequence and DNA computing to encapsulate shares and generate private keys for the server and the client.

As a result, the proposed algorithm prove an able to resistance exhaustive, entropy, statistical attacks and prevent phishing attacks.

In addition to, the proposed visual cryptography equations able to rebuild same quality and size of the secret color image.
