Authentication validates a user's identity by using something they know, have, or are. Common authentication methods include passwords which are something known, tokens like keys which are something had, and biometrics like fingerprints which are something a user is. A 3D password aims to improve authentication security by combining recognition, recall, tokens, and biometrics within a virtual 3D environment that requires users to interact with objects in a specific sequence.
3D password
- 2. Authentication Authentication is a process of validating who you are to whom you claimed to be. Human authentication techniques are as follows: 1.Knowledge Based (What you know) 2.Token Based(what you have) 3.Biometrics(what you are)
- 3. Three Basic Identification Methods of password Possession Knowledge (“something I have”) (“Something I know”) •Keys •Password •Passport • Pin •Smart Card •Face Biometrics •Fingerprints (“something I am”) •Iris
- 5. • Password is basically an encryption algorithms. It is 8-15 character or slightly more than that. Mostly textual passwords nowadays are kept which are very simple.
- 6. Passphrase It’s the enhance version of password. It is a combination of words or simply collection of password in proper sequence. It contains any well known thought also. Length of passphrase is about 30-50 character or more than that also.
- 8. Biometrics •Refer to a broad range of technologies. •Automate the identification or verification of an individual.
- 9. Based on human characteristics or body organs

- 13. PASSWORD •How secure is your password? Now with the technology change, fast processors and many tools on the Internet, cracking password has become a Child's Play. Ten years back Klein performed such tests and he could crack 10-15 passwords per day.
- 14. PASSPHRASE •Passphrase length is about 30-50 characters or more than that so it creates ambiguity to remember if there is no any proper sequence.
- 15. BIOMETRICS •Biometrics has also some drawbacks. Suppose you select your fingerprint as a biometrics.. But what to do when you have crack or wound in your finger. And now a days some hackers even implement exact copy of your biometrics also….
- 16. 3D PASSWORD
- 17. •The 3D passwords which are more customizable, and very interesting way of authentication. •A 3D password is a multifactor authentication scheme that combine RECOGNITION +RECALL +TOKENS +BIOMETRICS in one authentication system.
- 18. The 3D password presents a virtual environment containing various virtual objects. The user walks through the environment and interacts with the objects. It is the combination and sequence of user interactions that occur in the 3D environment.
- 19. This is achieved through interacting only with the objects that acquire information that the user is comfortable in providing. It becomes much more difficult for the attacker to guess the user’s 3-D password.
- 20. Virtual objects Virtual objects can be any object we encounter in real life: A computer on which the user can type in A fingerprint reader that requires users fingerprint A paper or white board on which user can type An Automated teller(ATM) machine that requires a token A light that can be switched on/off A television or radio A car that can be driven A graphical password scheme

- 23. 3D Virtual Environment •3-D virtual environment affects the usability, effectiveness, and acceptability of a 3-D password system. • 3-D environment reflects the administration needs and the security requirements. 3D Virtual Environment
- 24. The design of 3D virtual environments should follow these guidelines: Real Life Similarity Object Uniqueness & Distinction 3D Virtual Environment Size Number of objects & their types System Importance
- 25. Advantages Flexibility Strength Ease to Memorize Respect of Privacy
- 26. Applications The 3D password’s main application domains are protecting critical systems and resources. Critical Servers Nuclear Reactors & military Facilities Airplanes and missile Guiding
- 27. A small virtual environment can be used in the following systems like- Atm Personal digital assistance Desktop computers & laptops Web authentication etc.
- 28. Attacks and Countermeasures Brute Force Attack Well studied Attack Shoulder-surfing Attack
- 29. Conclusion •The authentication can be improved with 3d password ,because the unauthorized person may not interact with same object at a particular location as the legitimate user. •It is difficult to crack ,because it has no fixed number of steps and a particular procedure. •Added with biometrics and token verification this schema becomes almost unbreakable.
