ABSTRACT
RFID (Radio Frequency Identification) is the quintessential pervasive computing technology. The heart of the utility is that RFID makes gathering information about physical objects easy. Information about RFID tagged objects can be read through physical barriers, and from a distance. Our project utilized these RFID tags to improve the security system of a building by introducing a system that could read the RFID tagged smart cards that are placed in proximity to an antenna. Our project comes with option of finger print system, GSM system and camera system attached with the main RFID system. This help in making the security full proof and reduce the possibility of breaches.
INTRODUCTION
The major problem faced by organizations in security breach is related with doors without proper security system on them for their protection. Our project is going to solve these problems by using RFID technology. For wireless data transmission between tag and sensor nodes, the project uses ZigBee modules.
Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. So the RFID is a wireless identification. Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag.
OBJECTIVE
The aim of the project is to design a system that have a small coverage area and can be use for authentication or identification purposes. “Security System Using RFID” is a system that uses RFID technology to maintain the security of the different rooms in same structure which can be monitored on real-time bases using the Database server (PC). This system prevents unauthorized entry in rooms. For this purpose we are introducing a multilevel security system which consists of finger print impression, camera and GSM module along with RFID system. This ensures the reliability of the system and makes it difficult to breach.
SYSTEM ANALYSIS EXISTING SYSTEM
In the existing system, Information is sent to and read from RFID tags by a reader using radio waves. In passive systems, which are the most common, an RFID reader transmits an energy field that “wakes up” the tag and provides the power for the tag to respond to the reader. Data collected from tags is then passed through communication interfaces (cable or wireless) to host computer systems in the same manner that data scanned from bar code labels is captured and passed to computer systems for interpretation, storage, and action. The drawback in this system is the lack of security option available for the user. One can easily use others RFID tag to gain access in the desired place without their prior knowledge. This breach cannot be easily accounted as there is no record other then the RFID tag used which can mislead to undesirable situation.
PROPOSED SYSTEM
This system is of new kind in which finger print recognition system along with GSM and camera is newly added. In this system RFID along with ZigBee, microcontroller, biometric system, GSM, amplifier circuit, power supply, camera and database server (PC) is used. Different circuits work together to form an unreachable system so that the security can be enhanced to the maximum level possible. When RFID tag is sensed by the RFID receiver and finger print impression is given, the camera is activated which clicks the image of the user trying to access the system. This information is stored in the database along with time and date when the system was accessed and the GSM technology used in the system make sure that the concerned authority is notified about the activation of the system along with result.
POWER SUPPLY
Power supply is the basic unit that provides corresponding operating voltage to each circuit. In this 12V power supply is used in the project. 7805 represents the IC which works on the operating voltage of +5V. 7905 represents the IC works on the operating voltage of -5V. 7812 represents the IC which works on the operating voltage of +12V. 7912 represents the IC works on the operating voltage of -12V.
CONCLUSION AND FUTURE IMPLEMENTATION
RFID is one of the best technology used for barcode system , tags and transfer information.
RFID adorns the management with a new idea and usher for a bright future.
In the near future the RFID tag system will be replaced with NFC(near field communication) because of its high sensitivity
Due to its customizable feature and continuing improvement the library communities are beginning to get involved in its development
