Abstract

Introducing a ground breaking approach for validation purposes, this document unveils the FreeHand Sketch-based Authentication Security System.  The biggest problem right now is how we protect our information in internet digital environment, which still has certain security flaws.  On-going security methods related to smartphone applications are mostly built with these security features like dotted patterns, biometrics, and iris and face recognition are the trendy methods. However, they are constrained in their own ways. Free-Hand Sketch Model enhances the basic and comparable security in digital accounts. The present research study made an attempt to make it easier in creating Free-Hand sketch passwords for easy remembrance. A simple Free-Hand sketch is an authorized model for the end users to create their own passwords against security attacks. The main methods suggested in this research study is Damerau-Levenshtein Distance (DLD) used to design Free-Hand sketch image processing model.
