FingerPrint Based Security System
Personal Safes are revolutionary locking storage cases that open with just the touch of your finger. These products are designed as secure storage for medications, jewelry, weapons, documents, and other valuable or potentially harmful items.These utilize fingerprint recognition technology to allow access to only those whose fingerprints you choose. It contains all the necessary electronics to allow you to store, delete, and verify fingerprints with just the touch of a button. Stored fingerprints are retained even in the event of complete power failure or battery drain.These eliminates the need for keeping track of keys or remembering a combination password, or PIN. It can only be opened when an authorized user is present, since there are no keys or combinations to be copied or stolen, or locks that can be picked.
In this project the fingerprint module from Miaxis Biometrics is used. It can store up to 750 finger prints on its own memory. It can be controlled through its serial port.
The microcontroller AT89S52 interact with the module. You can Add a fingerprint, Delete a fingerprint and Identify the fingerprint.
To add a fingerprint, just show the finger on the module and press the ADD key. Now the microcontroller will send the ADD command to the module and the module will add it into the memory.
To delete the finger follow the same as above.
To identify the finger, press the Identify button and if the finger matches then the Relay is complemented. Also the fingerprint ID is displayed over the LCD display.

FingerPrint Based Security System
[attachment=16734]
Objective
Nowadays accurate personal identification is becoming more and more important. Usual means (smart cards, passwords…) have shown their limits (falsification, loss…). Biometrics (i.e. analysis of personal biological characteristics) can bring a satisfying answer to those latter problems. Currently fingerprint recognition is the most widely used technique for personal identification. Fingerprints are made up of locally parallel ridges with singular points (minutiae), and they constitute a unique permanent universal pattern. The use of ink and paper to get an image from a finger was used for a long time, but technological advances have enabled to automate the acquisition stage by means of solid-state sensors. These sensors exploit different techniques to acquire the image (pressure, electrical field, temperature…) and require a static (matrix sensor) or mobile finger position (sweeping mode sensor).
Principle of operation
When a finger is kept at the finger print reader, it will give the information accordingly to microcontroller by sending appropriate commands to the reader and which is displayed on the LCD. If the information matches with the one within the device then the DC motor interfaced to the microcontroller responds accordingly. And if the information provided by the user is incorrect or mismatch in finger prints is detected then access is denied. Finger print reader and the microcontroller unit are connected using serial interface.
Embedded Systems
Embedded System is a combination of hardware and software used to achieve a single specific task. An embedded system is a microcontroller-based, software driven, reliable, real-time control system, autonomous, or human or network interactive, operating on diverse physical variables and in diverse environments and sold into a competitive and cost conscious market.
Examples of Embedded Systems
An embedded system typically has a specialized function with programs stored on ROM. Examples of embedded systems are chips that monitor automobile functions, including engine controls, antilock brakes, air bags, active suspension systems, environmental systems, security systems, and entertainment systems. Everything needed for those functions is custom designed into specific chips. No external operating system is required.
Characteristics of Embedded System:
• An embedded system is any computer system hidden inside a product other than a computer
• There will encounter a number of difficulties when writing embedded system software in addition to those we encounter when we write applications
Applications
• Personal laptops and ATM
• Door lock system and Safe box
• Vehicles
• Industry
