3. Commonly used authentication schemes are textual passwords, graphical passwords and biometrics. 3D password is a multifactor authentication scheme. To be authenticated, werequirea3Dvirtualenvironment. INTRODUCTION

4. Combines recognition-,recall-,token-,and biometrics-based systems. Users choice to select the type of authentication technique.

5. KNOWLEDGE BASED Recall based Recognition based TOKEN BASED eg : smart card AUTHENTICATION SCHEMES

6. BIOMETRIC BASED Fingerprint,palm prints,hand geometry,face recognition Intrusiveness upon a user’s personal characteristics. GRAPHICAL PASSWORDS Recognition based Recall based

7. New scheme should combine the existing authentication schemes Freedom to select the type of authentication technique. Should provide secrets that are easy to remember,difficult toguess. FUNCTIONALITIES REQUIRED

8. 3D environment space represented by the co-ordinates User navigate into the 3D virtual environment using any input device. The sequence of actions and interactions forms the users3D password. 3D PASSWORD SELECTION AND INPUT

17. Commonly used authentication schemes are vulnerable to attacks. 3D Password is a multifactor authentication scheme. Design of 3D virtual environment, selection of objects inside the environment, and the object type reflects the resulted password space. User’s choice and decision to construct the desired and preferred 3D password CONCLUSION
