Abstract: In this study, we have proposed a method which combines the overlaying of 3D graphics in computing world by means of Augmented Reality (AR) technology. Our paper provides the security for the data’s in the database through the QR codes. This technology is mainly used for applications like security protection for military details, student information and also in medical fields, etc. The main objective of this is overlaying of the virtual object into the real world with the help of system and web camera, which gives sensitive vision to the researcher and which makes the object as a 3D projection in a real time processing technology. By using this technology it is used for security applications like Biometrics, QR codes also. It is used for high security applications like student document verification, military database, etc. Some profits in this can also be improved by QR codes as they are used in tracking and enemies prevention security systems also. Since, it is an emerging and well growing technology, AR applications requires some special devices. Because of the special devices it is very expensive generally. But in our dissertational work, we have proposed an AR methodology for the 3-Dimensional contest with a very low cost by using AR and QR codes.
