IRIS Recognition Technology
[attachment=30110]
Introduction
Iris Recognition is a Biometric Technology which deals with identification based on the human Iris.
It is considered to be the most accurate biometric technology available today.
Irises can be used to identify individuals rather than just confirm their given identity.
Specification
Minimum Requirements
read in an image of an eye and display this on
screen.
calculate features of the iris pattern
Encoding the Iris
The iris is encoded to a unique set of 2048 bits which serve as the fundamental identification of that person’s particular iris.
These iris bit codes can be stored in a database and then compared to uniquely identify a person.
Final Results
With the batch command line option of the application, it is possible to process a large amount of images of eyes.
Using this option, 108 images of eyes from the database were loaded into the application; the pupil, iris and eyelids were auto-detected to generate a bit code and store it in the database.
Applications
The largest application of iris recognition has been in the aviation industry.
Many of the worlds largest airports like the Heathrow airport of London, employ iris recognition.
The largest use of iris recognition is in United Arab Emirates, where millions of Iris Code comparisons are done each day at all the air, land and sea ports.
Used for Security for government applications.
Used by police departments and government security agencies to keep a record of criminals or suspects.
Conclusion
The Iris technology combines computer vision, pattern
recognition, statistical inference, and optics. Its purpose
is real-time, high confidence recognition of a person’s
identity by mathematical analysis of random patterns
that are visible within iris of an eye from some distance.
Users no longer have to worry about remembering
passwords and system administrators no longer need to
worry about the never-ending problem of users disclosing
passwords or having weak passwords that are easily
cracked.
