3. Objectives
 Through conducting online survey and
locating the advantages, see how people can
benefit from the Fingerprint recognition
System.
 As an innovative technology, is this system
still has its market value or not?

4. 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.

6. 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

7. Used fingerprint sensor
technologies
Optical
- Involves capturing a digital image
of the print using visible light
- Type of sensor：Specialized
digital camera

8. 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

9.  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.

10. 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

11. 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

12. 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.

14. Application
E-channel (identify you when immigration)
Access to car

15. Access to device(Smartphone)
An USB Biometric Fingerprint
Reader Password Lock
To protect your computer by
preventing unauthorized access
and encrypting data in the
computer.

16. 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.

17. 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.

18.  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.

23. Online Survey
 Aim: Find out the situation of using
Fingerprint Recognition System
nowadays and the opinion of people on
the advantages of this System.
 Survey Link: http://goo.gl/b8VXB
 No. of responds:37

24. Survey Questions
 Q1: Have you ever used the following
applications of Fingerprint Recognition
System?
 Q2: How often do you use Fingerprint
Recognition System?
 Q3: Have you experienced failure of using
Fingerprint recognition system?
 Q4: Do you agree the following advantages
of Fingerprint Recognition System?

Have you ever used the following applications of Fingerprint Recognition
System?
Identification in immigration
and emigration (E.g. E-
channel)
Access to high secure places
Access to public buildings or
areas
Login to computers or other
digital devices
Protect the data, not allow
others to access the private
data on computers
Others
Never

26. 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.

How oftendo you use FingerprintRecognitionSystem?

28.  43% of respond said that they use
Fingerprint recognition System one to
three times per year while 27% used it
one to five times in half of year.
 Since many responds are teenagers in
this survey, they may not use it very
often. Mostly, they use this system to
immigrate only.

System. It means this technology is not
100% reliable and sometimes error
would occur.
 There are many rooms for improvement
of this system.

33. Conclusion
 Failure of identify people due to skin
conditions or other reasons so touch-
less fingerprint recognition system can
make improvement on this situation.
 Although the tool sometimes cannot
identify people, it is still a
helpful, convenient and reliable
innovation in nowadays.

34. 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.
