Iris scanners form a new generation of technology, using a regular video camera style, “that store digital images of people’s eyes in a database and is considered a quicker alternative to fingerprints.” (Sept. 13, 2010 USA TODAY)
Iris scanning can be done as far away as six feet. Verification time is less than 5 seconds. A false eye can be detected by varying the light shone into the eyes and watching for pupil dilation. Features that exist in the colored tissue surrounding the pupils are analyzed. Over 200 points can be sued for comparison, including rings, furrows, and freckles.
The uniqueness of eyes, even between the left and right eyes of the same person, makes iris scanning a powerful tool for identification purposes.
Police stations, prisons, airports, the U.S. military, and banks are all interested in this latest means of identifying a person.
Homeland Security is planning a two-week test of commercially sold iris scanners at a Border Patrol Station in McAllen, Texas.
“The test will help us determine how viable this is for potential (department) use in the future,” said Arun Vemry, program manager at the department’s Science and Technology branch.
Jesus of Nazareth once said, “The eye is the lamp of the body.” (Luke 10)
Truly it is.
When it comes to what points out, unerringly, with what person, made in God’s image and likeness (Genesis 1:26), we are dealing…
The eyes have it.
“Truly,” says King David in Psalm 139, “you have formed my inmost being. You knit me in my mother’s womb. I give you thanks that I am fearfully, wonderfully made. Wonderful are your works!”
