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

Principle

Constancy

➢ Remaining unchanged during an individual’s lifetime

Variation

➢ Failing to find the identical fingerprint in different people

Infallibility

• 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

Composition of patterns

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

Prospect and development

Advantages

Uniqueness

➢ Guaranteeing all application and avoiding frauds in most cases

Highly reliable

➢ Preventing error

Reduce human workload

➢ Matching process in computer

➢ Reducing cost

Disadvantages

Costly

➢ Applying technology involves higher cost periodically

Error instance

➢ Causing distortion record

➢ Making error

➢ Immature technology

➢ Accepting fake fingerprint occasionally

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
