Password Processing Techniques using Visual Cryptography and Optical Character Recognition

Abstract

In recent years, the transformation of the password for client authentication is to convert the password into hash values. Yet, these passwords dependent on has values are basic and quick because those are in the type of text and renowned cryptography. Because of this, the secret phrase can be efficiently broken by utilizing the cracking tools. Attackers can without much of a stretch hack the password if they know the hash value when they are simple and plain text. To overcome all these impediments, new schemes are suggested to process the passwords using visual cryptography (VC) and optical character recognition (OCR).VC is a cryptographic strategy that permits visual data to be encoded in such a way the decryption can be performed by the human visual system, without the guide of computers. As it doesnt require any key to decode that is the reason this strategy is unbreakable. The methodology of VC is totally unique in relation to the existing techniques, where the client ID of text type and is changed into two encoded pictures. The server will have a client ID and one the encrypted picture, client send the another picture to the server when it needs to login then the server extricates the ID by utilizing the OCR. At last by comparing the extracted ID with the one stored at server user authentication will be successful. This plan helps in reliable authentication that prevents cyber-attack and required minimum computation time when contrasted with other strategies. This method can be utilized in e-commerce websites, banking applications, and many other government websites. To develop a new techniques and to improve the efficiency of these algorithms one must have a strong foundations, in this paper we have provided a brief review about the VC and OCR presented along with the recent research works.
