fingerprint technology

4. DEFINITION:
“A Finger Print is made up ridges and grooves.
Such a technology which uses the ridges and
grooves of a finger is called finger print technology.”
 The system locates the minutia points
 These minutia points occur where the lines of ridges
Begin.
 These points are then mapped and a line is drawn between
Each point.
 The map shows relation between all the points.

5. HISTORY OF FINGERPRINT TECHNOLOGY:
 In 1892, in Argentina inspector Eduardo Alverez made
the first fingerprint identification.
 He was able to identify a woman who murdered her
two sons and cut her own throat to place blame on another
FINGERPRINT SCANNER:
 Fingerprint scanner uses the combination of hardware &
software techniques to recognize a fingerprint.
 Safer method than password, that can be lost or forgotten.
 It uses USB fingerprint scanner with biometric software
for authentication, identifications and verification of a
fingerprint

6. TYPES OF SENSORS USED IN FINGERPRINT
SCANNER:
 Capacitive sensors
 Optical sensors
 Thermal sensors
 Rf sensors
 Ultrasonic sensors
WORKING OF FINGERPRINT SCANNER:
There are two main ways of scanning fingers:
 optical scanning
 capacitive scanning

7. OPTICAL SCANNING:
 It shines a bright light over your finger and takes a digital photograph.
 The image gets feed in a computer scanner.
 The scanner uses a light sensitive microchip to produce a digital image.
 The computer analyzes the image and convert it into code.

8. CAPACITIVE SCANNING:
 Capacitive scanners measures your finger electrically.
 While resting on a surface, the ridges in your fingerprint
touches the surface while the hollow between the
ridges stands clear out of it.
 A capacitive scanner builds up an image of your finger
with these varying distances between each part of your
finger and the surface below.
 Scanners like this are like touchscreens of iPads & iPhones

9. IDENTITY ACCESS MANAGEMENT:
 Fingerprint based access control is way more effective
than identity cards.
CRIMINAL INVESTIGATION:
 Police departments are using fingerprint access to
speed up investigation.
Background check:
 Use fingerprint scanner to crosscheck an employee’s
Fingerprints against the FBI fingerprint database can
Detect persons with criminal record.

10. EDUCATION:
 Fingerprint scanners can be used to regulate students’
Attendance instead of using student cards.
SMART PHONES:
 Modern phones have fingerprint technology for unlocking
Purposes instead of passwords. It makes phones more secure.
REDUCING CARBON FOOTPRINT:
 Biometric based technology is eco friendly. It eliminates the
need of id cards and reduces plastic waste.

11.  IDENTITY CARD SOLUTIONS:
 Fingerprint based access control is more effective than traditional identity cards in both
enrollment and operational conditions
 HOSPITALS AND CLINICS:
 Fingerprint readers are put at the entrance of all areas and wards of hospital for
identification of patients and staff members
 GYMS AND FITNESS CENTERS:
 In gyms and fitness centers a fingerprint based authentication system increases
convenience as members do not need to carry membership cards and keys , and risk
losing them

12.  Improved security
 Improved customer experience
 Cannot be forgotten or lost
 Easy to use
 Require little space
 Large amount of existing data to allow background and
watch list checks
 Mature technology
 Long term stability
 Large database exists
 Uniqueness
 Universality
 User friendliness
 Comfort

13. Disadvantages of finger print technology are:
 Inability to enroll some users
 Affected by skin conditions
 Association with forensic applications costly
 Privacy concerns of criminal implications
 Environment and usage can affect measurement
 Systems are not 100% accurate
 Require integration and additional hardware
 Cannot be reset when compromise
