Introduction of Fingerprint Recognition System
This is one of the Biometric devices that is identification or verification of a person by using biological and physical characteristic such as iris, speech, face, fingerprint, etc.
Fingerprint recognition System identifies people by using Fingerprint.

Introduction of Fingerprint Recognition System
Fingerprint application - Life is easier and convenient! (At Home) – YouTubehttp://www.youtube.com/watch?v=9mm3oXnT7do

Fingerprint sensors An electronic device is used to
capture a digital image of the fingerprint pattern
Captured image is called a live scan Live scan is digitally processed to
create a biometric template

Used fingerprint sensor technologies
Optical- Involves capturing a digital image of the print using visible light
- Type of sensor: Specialized digital camera
![Page 8: Fingerprint Recognition System](https://reader035.fdocuments.us/reader035/viewer/2022062313/5587e753d8b42a222d8b45f9/html5/thumbnails/8.jpg)
Ultrasonic- Use of the principles of medical
ultrasonography
- It uses very high frequency sound waves to penetrate the epidermal layer of skin
- Advantage: create a clean, undamaged epidermal skin and a clean sensing surface
![Page 9: Fingerprint Recognition System](https://reader035.fdocuments.us/reader035/viewer/2022062313/5587e753d8b42a222d8b45f9/html5/thumbnails/9.jpg)
Capacitance- Utilizes the principles associated with
capacitance in order to form fingerprint images
- Sensor array pixels → one plate of a parallel-plate capacitor;
- The dermal layer (which is electrically conductive) → the other plate;
- The non-conductive epidermal layer → dielectric.
![Page 10: Fingerprint Recognition System](https://reader035.fdocuments.us/reader035/viewer/2022062313/5587e753d8b42a222d8b45f9/html5/thumbnails/10.jpg)
Passive capacitance
- Principle: To form an image of the fingerprint patterns on the dermal layer of skin
- Each sensor pixel is used to measure the capacitance at that point of the array
![Page 11: Fingerprint Recognition System](https://reader035.fdocuments.us/reader035/viewer/2022062313/5587e753d8b42a222d8b45f9/html5/thumbnails/11.jpg)
Active capacitance- Use a charging cycle to apply a voltage
to the skin before measurement takes place
- Advantage: create a clean, undamaged epidermal skin and a clean sensing surface.
- Active capacitance sensors measure the ridge patterns of the dermal layer like the ultrasonic method

Patterns of Fingerprint Ridges Arch: The ridges enter from one side of
the finger, rise in the center forming an arc, and then exit the other side of the finger.
Loop: The ridges enter from one side of a finger, form a curve, and then exit on that same side.
Whorl: Ridges form circularly around a central point on the finger.

Different kinds of Fingerprint Door Lock
To enhance the security of places such as home.
can easily add and remove people that require temporary
admission to the place.

Advance Technology Touchless or contactless finger imaging is
essentially a remote sensing technology used for the capture of the ridge-valley pattern with no contact between the skin of the finger and the sensing area.(Giuseppe Parziale and Yi Chen, 2009)
It is used the camera and
LED light to capture
fingerprint image.
![Page 18: Fingerprint Recognition System](https://reader035.fdocuments.us/reader035/viewer/2022062313/5587e753d8b42a222d8b45f9/html5/thumbnails/18.jpg)
Reasons that touchless fingerprint recognition system is better than the touch-based one:
Touch-based Touchless
Affected by skin conditions E.g. Dry skin or Wet skin
Capture fingerprint images consistently because it is not affected by different skin conditions.
The fingerprint image will be different due to different pressure when put our finger on the sensor.
Avoid the fingerprint image distortion.

Analysis 1 The above pie chart reflects that almost
a half of respond have used E-channel which takes 47% and 16% of respond have used Fingerprint recognition System to login some electrical devices.
We can observe that Fingerprint recognition System is very common used and helpful in our daily life.

Conclusion Majority of people use E-channel, it
saves time when immigrate. The tool can highly increase the security
of places and devices. Also, the price of the tool is lower while the technology is developed rapidly, it is worth buying.
