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?

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

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

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.

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

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.

ApplicationE-channel (identify you when immigration)

Access to car

Access to device(Smartphone)

An USB Biometric Fingerprint Reader Password Lock

To protect your computer by preventing unauthorized accessand encrypting data in the computer.

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.

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.

Mind Map

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

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?

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 often do you use Fingerprint Recognition System?

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.

Have you experienced failure of using Fingerprint recognition system?

Series1

Over half of respond have experienced failure of using Fingerprint recognition System. It means this technology is not 100% reliable and sometimes error would occur.

There are many rooms for improvement of this system.

Do you agree the following advantages of Fingerprint Recognition System?

Strongly Agree Agree Neutral Disagree Strongly Disagree

There are almost 20 responds agree that Fingerprint recognition System are reliable, convenient, user-friendly and safe etc. Only a few respond cannot benefit from this system.

This system brings a great deal of advantages in our life which can be considered as a great innovation.

Analysis 4

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.

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.
