Iris recognition has been touted as a reliable biometric measurement because it’s a body feature that doesn’t change over time. However, researchers from the University of Notre Dame are finding that the iris is susceptible to aging and may indeed change over time, refuting the notion of “one enrollment for life.”

As reported on The Cutting Edge News, Kevin Bowyer, the Notre Dame Schubmel-Prein Family Chair in Computer Science and Engineering, has conducted experiments that show increases in false non-match hits over time, which indicates that aging is a factor in iris recognition. This information is coming to light now that researchers have access to several years of data.

Iris recognition systems have been implemented in many airports and border crossings worldwide, however, this new information may not be a detriment to these systems, provided that companies find work arounds for the aging process.
