This document discusses the weaknesses of text-based passwords and proposes an alternative graphical password system. It summarizes that existing login systems use usernames and passwords but are vulnerable to shoulder surfing, keyloggers, and bots. It then describes a graphical password system that displays a grid of images for the user to click in a specific pattern to log in, avoiding these threats. System requirements of the proposed graphical password system are also listed.

2.  Existing System Contains User_Name and
Password Based Method.
 Threats To The Existing
System are :
Shoulder Keylogger Bots
Surfing

3.  When users input their passwords in a public
place, they may be at risk of attackers stealing
their password. An attacker can capture a
password by direct observation.

4.  Key stroke are recorded
 Threat to login system as
the username and
password recorded
Bots
Perform simple and repetitive tasks

5. Text Based Password are subject to attacked by
following ways
 In shoulder surfing attacker can capture a
password by direct observation
 In key logger attacker record the individual’s
authentication session.
 In bots attack the automated or semi-automated
robots do the same

6.  Sensitive Information requires high security
 Authentication processes to keep information
secure
Authentication Methods
Graphical Image Based
Password Based Password

7.  If password is “deokar”

9.  A grid of image is displayed, where the user
will select a particular images from the grid.
 The aim of this authentication is to avoid attack
from a script or another machine.
 A keylogger or bot attack can be avoided.

12.  HARDWARE:
 Processor: Pentium-IV 1.5 GHz and above
 Ram: 256 MB minimum
 512 MB preferred
 Monitor: 15 inch
 CD-ROM: 52x speed
 SOFTWARE:
