Iris scanning uses the unique patterns in a person's iris, which are determined before birth and remain stable throughout life, allowing for highly accurate biometric identification. An iris code using a mathematical algorithm represents each iris pattern, and no two codes are the same. Current uses of iris scanning include smartphones, airports, and government and military applications due to its accuracy and speed compared to fingerprint scanning. Future uses may expand to ATMs, healthcare, transportation, and other areas requiring security and user identification.

1. Iris Scanning
Taryn Atkinson

2. Why the Iris?
 Color is determined by genetics
 Patterns in the ligaments are
formed by random tissue folding
during gestation
 Patterns remain stable
throughout life
 225 different points of
comparison

3. How it Works
 Iris Codes
 John Daugman
 A mathematical equation that
represents the pattern in a
person’s iris
 No two codes are the same
1. Enrollment
2. Recognition

4. Current Uses
 Most common use in
private enterprise,
military, and
government
 Samsung Galaxy Note 7
 Fujitsu NX F-04G
 Infrared LED and
infrared camera
 Reviews: faster and
more accurate than
finger scan
 Airport security

5. Future Use
 ATMs
 Healthcare, financial, and
transportation
 Prisons
 Faster way to log
 Security
 Traffic cameras
