Abstract: Traditional password conversion scheme for user authentication is to transform the passwords into
hash values. These hash-based password schemes are comparatively simple and fast because those
are based on text and famed cryptography. However, those can be exposed to cyber-attacks
utilizing password by cracking tool or hash-cracking online sites. Attackers can thoroughly figure
out an original password from hash value when that is relatively simple and plain. As a result,
many hacking accidents have been happened predominantly in systems adopting those hash-based
schemes. In this work, we suggest enhanced password processing scheme based on image using
visual cryptography (VC). Different from the traditional scheme based on hash and text, our
scheme transforms a user ID of text type to two images encrypted by VC.
The user should make two images consisted of subpixels by random function with SEED which
includes personal information. The server only has user’s ID and one of the images instead of
password. When the user logs in and sends another image, the server can extract ID by utilizing
OCR (Optical Character Recognition). As a result, it can authenticate user by comparing extracted
ID with the saved one. Our proposal has lower computation, prevents cyber-attack aimed at
hashcracking, and supports authentication not to expose personal information such as ID to
attackers.
