Advantages And Disadvantages Of Password

We have to think that how much our password and other authentication schemes are powerful to protect our data and documents from hackers .it is very easy for hackers to hack our data. .There is different authentication scheme to provide security to our data like TEXTUAL PASSWORD ,GRAPHICAL PASSWORD , BIOMETRICS. But current authentication scheme are suffering from many weaknesses. 3D Password authentication scheme is combination of RECOGINATION , RECALL , TOKENS , BIOMETRICS. 3D Passwords is more secure way of authentication and it is more interesting way, because it present a VIRTUAL ENVIRONMENT containing various virtual objects.

It is the combination and sequence of user interactions that occur in the 3D environment. It is more difficult

PASSWORD AUTHENTICATION

Password is nothing but just a string of character which allow user to access computer, interface or some system. In other words we can say password is basically a encryption algorithm.

A. ENCRYPTION ALGORITHM

It is a mathematical procedure for performing encryption on data. The encryption on data is just to translate data into a secure code. Encryption is more effective way of achieving security.

B. PASSPHRASE

Passphrase is a sequence of word or other text which allow user to access computer data. Passphrase are long in compare to password . Easier to remember and type, and difficult to crack in compare to password because of length.

III. TOKEN AUTHENTICATION

Token is a small hardware or software device that owner carries with him to access his data. It is based on multifactor authorization. A Token could be a keyword , an operator or a punctuation mark. Tokens is of several types:-

 Connected token : Smart card

 Disconnected token : RSA Secure ID token

 Contactless token : Bluetooth

 Mobile Token : One Time Passcodes (OTP)

IV. BIOMETRICS

The technology is mainly used for identification and access control, or for identifying individuals that are under surveillance. In computer biometrics refers to the authentication. It can be either an ‘identification’ system or a ‘authentication’ system.

Example:- face, fingerprints, iris etc.

V. 3D PASSWORD

The 3D Password is multifactor authentication scheme which combine advantages of some other authentication schemes. The 3D password is a more customizable and very interesting way of authentication. The 3D Password presents a virtual environment containing various virtual objects. In this user can interact with objects of environment. The 3D Password is simply the combination and the sequence of user interactions that occur in the 3D virtual environment. Virtual objects can be any object that we encounter in real life.

3D Password is used to overcome the drawback and limitations of textual password, graphical password, etc.It is also used to design and develop more user friendly & easier authentication
