Authentication of any system means providing a security to that system. There are number of authentication techniques like textual, biometrics etc. This type of textual password commonly follows an encryption algorithm to provide security. Each of these techniques has some limitations and drawbacks. To overcome the drawbacks, a new authenticate technique is now available. This new authentication technique, known as 3D Password, is multi-factor and multi-factor authentication technique. The most important part of 3D Password is virtual environment containing the user interface which looks like a real time environment, but is not actually a real time environment [3]. 3D password is more secure technique of authentication in comparison to other techniques because it is difficult to break and simple to use [1]. The advantage of the 3D password is that combine the authentication of existing system and providing high security to user.[2]. This paper focuses on how to create 3D password and the design principles for 3D password.

In the Smt. Chandaben Mohanbhai Patel Institute of Computer Applications, Charusat, allocation of subjects to faculties at the start of each new semester of academy year is a complex and tedious process. We propose a decision support system that attempts to maximize satisfactions for the overall faculty group. The system is able to improve the satisfaction level to 80%, even though some of the subjects may be heavily prioritized by faculty. Concept of Data Mining is used and it is shown to be effective. Results of subject allocation by the system have been positive. The system will greatly reduce the complex manual work of Principal/HoD for subject allocation. In addition, it will result in significant time saving for the Institute's Subject Allocation Committee.
