Fingerprinting has been used for over 100 years, first as evidence in criminal cases and now widely for security and identification. The document discusses the history and principles of fingerprinting, how fingerprints are captured, and applications like smartphone unlocking and immigration. A survey found over 90% of respondents had used fingerprinting services before, mostly for smartphone unlocking. While fingerprinting is highly reliable, issues remain around costs, errors, hygiene, and privacy protection.

5. Background - History
● 1858 - Required fingerprinting and signatures on civil contracts
● 1892 - Published the first book on fingerprinting
● 1901 - Used as evidence
● 1905 - Adopted the fingerprinting on US military
● 1999 - Kept fingerprint record
● Now - Use the fingerprinting all over the globe

6. Principle
Constancy
➢ Remaining unchanged during an individual’s lifetime
Variation
➢ Failing to find the identical fingerprint in different people
Infallibility

7. Composition of patterns
• 60-65% of the population
• Having one or more ridges
• Passing through an imaginary line from delta to
core
Loop
• Having only 5% of the population
• Having no delta
• Flowing in one side and flow out the opposite
side
Arch
• 30-50% of the population
• Consisting of a series of almost concentric
circles
Whorl

8. Ways to capture a fingerprint
Optical Way
• Scanning the
fingerprint by a
scanner
• Recording its
reflection patterns
images
• Disadvantage:
• Causing the
distortions of
fingerprint
occasionally
Thermal way
• Using thermal
detector to
determine the
fingerprint
• Disadvantage:
• Causing the
distortions of
fingerprint
occasionally
3D Scanner
• New Innovation:
Having developed
in 2010
• Avoiding
distortions of the
fingerprint images
• Being
uncommonly used
in Hong Kong

9. Application
Identifying People:
➢ Immigration system
➢ Criminal investigation
Security Access:
➢ Smartphone unlocking
➢ Electronic door lock

10. Application - Identifying people
Immigration
➢ Matching image and data of fingerprint in ID card
➢ Facilitating automated passenger clearance system from 2004
(e.g. e-channel)
Criminal investigation
➢ Being evidence in criminal cases

11. Application - Security access
Smartphone unlocking
➢ Improving portability
➢ Saving the uniqueness fingerprint as encrypted biometric key
➢ Swiping the finger to unlock
Electronic door locks
➢ Being safe and secure
➢ Having same function as usual door
➢ Saving over 200 different fingerprints
➢ Receiving a set of emergency access keys

16. Prospect and development
Fingerprint credit card
➢ Having small fingerprint scanner
on credit card
Biometric gun
➢ Requesting the owner’s
authorized fingerprint to unlock
➢ Controlling the gun safety

17. Advantages
Uniqueness
➢ Guaranteeing all application and avoiding frauds in most cases
Highly reliable
➢ Preventing error
Reduce human workload
➢ Matching process in computer
➢ Reducing cost

18. Disadvantages
Costly
➢ Applying technology involves higher cost periodically
Error instance
➢ Causing distortion record
➢ Making error
➢ Immature technology
➢ Accepting fake fingerprint occasionally

19. Disadvantages
Hygiene problem
➢ Transmittiing bacteria during using fingerprint scanner
Privacy matters
➢ Having risk of leaking personal data
➢ Problem: Stealing your fingerprint for other purpose by device’s owner
➢ Solution: Setting regulations protecting privacy
