This document proposes a new shoulder surfing resistant graphical password scheme. It begins with an introduction to passwords and why they are needed for authentication. It then discusses different types of existing graphical passwords like passfaces, passpoints and draw-a-secret (DAS). The document outlines the working of current text-based graphical login systems and their drawbacks. It proposes a new login system using QR codes and password encryption to address these issues. It describes the current and future applications of this system and the hardware and software requirements. The document discusses the advantages of the new system in reducing shoulder surfing attacks and sending alerts on wrong attempts. It concludes that the proposed text-based color password scheme satisfies usability and security requirements.

3. PASSWORD
oThe most commonly used form of User authentication
oVarious types of passwords
oStrength of password
oEvolution of password technique

4. TYPES OF GRAPHICAL PASSWORD
Pass faces Pass Points DAS (Draw-A-Secret)

5. oPass faces
• Faces are used as a graphical portfolio
• Preference could be a limitation
oPass Points
• Use “a sequence of clicks” as a shared secret
• There are hot spots
oDAS(Draw A Secret)
• Use “a sequence of clicks” as a shared secret
• There are hot spots

6. WORKING OF EXISTING GRAPHICAL TEXT
BASED LOGIN SYSTEM
oFill the registration form
oEnter text based user name
oChoose type of password Text/Graphical
oAdvantage of graphical password
oDrawback of existing system

7. NEW USER REGISTER

Proposed System

8. ADVANCEMENT IN GRAPHICAL PASSWORD
oUse of QR code instead of textual user name
oUsing password encryption technique
oSending alert message to user if attacker attempts to login

9. CURRENT SCOPE
oLocking folder’s
oLock application for smart phones
oSecuring Hard Disk

10. FUTURE SCOPE
oATM Login System
oWeb based login

11. DETAILS OF SOFTWARE REQUIREMENTS
oNetBeans IDE 8.02
oJava 1.8
oSql server for database connectivity

12. DETAILS OF HARDWARE REQUIREMENTS
oMinimum hard disk space required 500GB
oMinimum RAM required 2GB
oProcessor Intel Core i3
oOperating system Windows 7

13. Advantages
o Easy to remember
o Reduced shoulder surfing attacks
o Alert message on wrong attempt
o Use of QR codes
Disadvantages
o Slightly time consuming

14. DO’S AND DON’TS FOR SECURED
PASSWORD
Do’s
oUse easy to remember textual based color codes
oEnter minimum 5 characters and maximum of 8 characters
oInclude special Characters to improve complexity
Don'ts
oDo not insert password which are easy to guess

15. CONCLUSION
oTextual based color passwords are an alternative to Picture
password.
oIt satisfies both conflicting requirements i.e. it is easy to
remember & it is hard to guess.
oBy the solution of the shoulder surfing problem, it becomes
more secure & easier password scheme.
oBy implementing encryption algorithms and hash algorithms
for storing and retrieving points, one can achieve more
security
oTextual based color password is still immature, more research
is required in this field.
