3D Password

3D passwords combine multiple authentication factors by using a 3D virtual environment. Users authenticate by interacting with virtual objects in a specific sequence based on their location. This addresses limitations of traditional passwords that can be cracked or stolen. The 3D password is constructed through a user's interactions in the virtual world, combining what they know, have, and do for strong multi-factor authentication. While providing increased security, 3D passwords also have drawbacks such as increased storage needs and vulnerability to timing attacks if the virtual environment is not carefully designed.
![How it Works?
• Let us consider a 3D virtual environment space of size G ×G × G.
The 3D environment space is represented by the coordinates (x, y,
z) ∈ [1, . . . , G] ×[1, . . . , G] ×[1, . . . , G].
• The objects are distributed in the 3D virtual environment with
unique (x, y, z) coordinates.
• The user can walk in the virtual environment and type something
on a computer that exist in (x1, y1, z1) position, then walk into a
room that has a white board that exist in a position (x2, y2, z2) and
draw something on the white board. The combination and the
sequence of the previous two actions towards the specific objects
construct the user’s 3D password.](https://image.slidesharecdn.com/3dpassword-140423014905-phpapp02/85/3D-Password-6-320.jpg)
3D Password
- 1. 3D PASSWORD By, R.Preethi M.Sc.,CS Dept of IT VHNSN College Virudhunagar
- 2. Authentication Authentication is the process of validating who are you to whom you claimed to be or a process of identifying an individual. It is generally based on the following as, 1.What you Know 2.What you have 3.What you are
- 3. Need For 3D Password • Textual Passwords User name and Password easy to crack, subject to Brute Force attack. • Graphical Passwords Recall and Recognize pictures, subject to shoulder surfing attack. • Biometrics Need special scanning devices to verify the users. • Smart Cards Can be lost or stolen, user want to carry everywhere.
- 4. 3D Password • 3D Password multi-factor Authentication scheme. • 3D Password combines all the authentication schemes – What you know – What you have – What you recognise – What you are
- 5. 3D Password • Presents a 3D virtual environment with various virtual objects. • It combines all existing scheme into one 3D virtual environment. • The 3D Password is constructed by the users interaction with the virtual objects on the virtual environment.
- 6. How it Works? • Let us consider a 3D virtual environment space of size G ×G × G. The 3D environment space is represented by the coordinates (x, y, z) ∈ [1, . . . , G] ×[1, . . . , G] ×[1, . . . , G]. • The objects are distributed in the 3D virtual environment with unique (x, y, z) coordinates. • The user can walk in the virtual environment and type something on a computer that exist in (x1, y1, z1) position, then walk into a room that has a white board that exist in a position (x2, y2, z2) and draw something on the white board. The combination and the sequence of the previous two actions towards the specific objects construct the user’s 3D password.
- 8. Security Analysis • Brute Force Attack Time Consuming Cost of Attack is more • Well Studied Attack Hard to accomplish, attacker has to perform customized attacks for different environment. • Shoulder Surfing Attack Attacker tries to record the user’s interaction with 3D virtual environment using camera. • Timing Attack Attacker observes the total time taken by the legitimate user to log in, it is possible if the virtual environment is poorly designed.
- 9. Application • Critical Servers • Online Banking • Nuclear and Military Facilities • Airplanes and Jetfighters • Web Authentications,ATM,Desktop or Laptop logins
- 10. Advantage • Provides strong security. • As this system is based on human quality recognize and recall, password cracking algorithms fail to crack these passwords. • The cost of forging information from 3D virtual environment is very high, therefore cracking the 3D password is more challenging. • As the authentication system is complex the hacker will have to study the new authentication schemes
- 11. Disadvantage • Space required to store the password is more. • Complexity is more in developing. • Timing attacks can be very effective if the 3D virtual environment is poorly designed. • Shoulder surfing is more vulnerable. So entering these passwords must be done in secured place.
- 12. Conclusion • 3D Password Provides – Flexibility: 3D Passwords allows Multifactor authentication – Strength: Provides almost unlimited passwords possibility. – Easy to Remember: can be remembered in the form of short story. – Privacy: Organizers can select authentication schemes that respect users privacy.
