SUIS: An Online Graphical Signature-Based User Identification System
Shahid Alam

TL;DR
SUIS is a novel online graphical user identification system that combines cognometric and drawmetric features using a 2D grid to create a secure, language- and device-independent signature-based authentication method.
Contribution
It introduces a new signature-based user identification system that leverages 2D grid technology without machine learning, enhancing security and usability.
Findings
Effective signature matching independent of sequence
Increased password space with more grid cells
Efficient for online authentication
Abstract
Humans possess a large amount of, and almost limitless, visual memory, that assists them to remember pictures far better than words. This phenomenon has recently motivated the computer security researchers' in academia and industry to design and develop graphical user identification systems (GUISs). Cognometric GUISs are more memorable than drawmetric GUISs, but takes more time to authenticate. None of the previously proposed GUISs combines the advantages of both cognometric and drawmetric systems. A signature personify a person and a graphical signature is easier to recall than other drawings. This paper proposes a new graphical Signature-based User Identification System named SUIS. It is based on a 2D grid technology, that is used to draw, digitize and store the signature for user identification. SUIS is categorized as both a cognometric and drawmetric system. Unlike other systems…
