3. Introduction
Graphical password is one of process for authentication in computer
system computer security is create a afe zone for our digital devices
Graphical password is a one of the processes to provide our security
of digital device or important information: As we know that our
human brain can easly store or recall an image or image-based
password. So, we propose graphical password for user who can
register mndom with highly secure and there is no difficulty to recall
the graphical password Authentication is a data access point that
manages consumer security assurance. It is a process that grants in a
particular context requinng the customer to Validation schemes are
categorized as token-based authentication, validation based on
biometrics, validation based upon knowledge Tokens are used as a
Hidden Key in token-based authentication.
4. OBJECTIVES
Graphical password authentication systems are a type of
Image-based authentication that attempt to understand the
human memory for visual information. In Pass Points,
passwords consist of sequence pixel click-points on a
given image. Users may choose one pixels in that image
as click-points for their password.
5. LITERATURE SURVEY
In Dec 2009 author H. Gao proposed graphical password scheme
using color login. In this color login uses background color which
decrease login time. Possibility of accidental login is high and
password is too short. The system developed by Sobrado is
improved by combining text with images or colors to generate
session passwords for authentication. Session passwords can be
used only once and every time a new password is generated. The
advantages of this system is that it reduces the login time, session
passwords are also generated to improve security. The
disadvantage of this system is that it the possibility of accidental
login is high and password is too short.
6. Functional Requirements
• Hardware requirements
• I3 processor or above
• 4gb ram or above
• 500gb Hard disk
• Internet connection
• Software requirements
• Operating system(Window, Linux ,Mac )
• Database Server
• Language(python)
• pycham
7. Problem statement
Alphanumeric password is an old traditional common
authentication method. Practically this traditional method is too
unsecure system. For example, attacker may choose easily
guessed user’s password, if user is not using a strong password.
User may use same password for multiple device or site. This are
all unsecure characteristic for normal users. And authentication is
one of the important security points where user has active
responsibility for their personal information security. If we use
old traditional password system then there may have possibility
to dictionary attack, Brute Force Attack.
9. Advantage & disadvantage
• Advantage:
1. The system is user-friendly and has an easy interface.
2.It provides strong security against bot attacks or hackers.
3.Protects systems exposed to attacks.
4.Graphical passwords systems provide a way of making more
human-friendly passwords.
5.Dictionary advances and brute power searches are infeasible.
6. Protects systems vulnerable to attacks.
• Disadvantage:
1. The only disadvantage is if users forget the password, it
cannot be retrieved.
10. Conclusion
In this extended abstract we are trying to make our authentication
system more user friendly and also we have tried to implement
mature & fast Shoulder Surfing Resistant Mechanism. We have
considered both methods: text based and graphical based systems
and tried to reduce the efforts required by end-user to remember
passwords. A look at the advancement in technology over the past
few years tells us that the next era will have system security at its
core. Thus Graphical Password may be adapted in future as a major
authentication system.
