Secure User Identification Using Visual Cryptography And Encryption Techniques
Abstract
This paper proposes a novel approach for user identification using visual cryptography, leveraging various schemes such as visual secret sharing and halftone schemes. User identifying data is divided into meaningful and meaningless shares, which can be merged to reveal the original content. To enhance security, encryption techniques are employed to conceal the data content, retrievable via decryption. User identification is based on the hidden data content within the shares. One share is stored on the server side while the other is with the user. During authentication, one share is displayed to the user from the server, matched with the user's share. This method ensures secure and unique user identification while preserving data confidentiality. The effectiveness of the proposed approach is demonstrated through experimental evaluation against various encryption and visual cryptography techniques.
