Published on

The purpose of this study is to identify the common causes of failure to acquire (FTA) in iris recognition technology. For the study, data that has been previously collected was examined and sorted into the areas of failure to acquire, the most common error, as well as interaction times. The goal of this process is to understand the reasons for these errors and how to correct them through efficiency, throughput, and security.

(Fall 2012) Success and Failure Rate of Iris Recognition

  1. 1. SUCCESS AND FAILURE RATE OF IRIS RECOGNITION The purpose of this study is to identify the common causes of failure to acquire (FTA) in iris recognition technology. For the study, data that has been previously collected was examined and sorted into the areas of failure to acquire, the most common error, as well as interaction times. The goal of this process is to understand the reasons for these errors and how to correct them through efficiency, throughput, and security. Max Charlot, Chris Livingston, Michael Brockly, Stephen Elliott Overview Number of Interactions 20 21 22 23 24 25 Number of people who finished within the given interaction 22 17 2 4 2 50 Table of Interaction Data Cause of Failure Left Eye Right Eye Complete Failure Complete Success Number of Failures 39/2231 539/2231 99/2231 677/2231 Percentage of Failures 1.75% 24.16% 4.43% 30.35% Success Rates 98.25% 75.84% N/A 69.65% 1.75% 24.16% 4.43% 69.66% Failure Rates FTA-Left Eye FTA-Right Eye Complete Failure Complete Failure – Failure to acquire either eye Complete Success – Successful recognition of both eyes FTA- Failure to Acquire What are the most common causes of FTA in iris recognition technology? Data will be collected and analyzed pertaining to: • Which eye had the most difficulty being captured? • Do users need the full 25 interactions to be captured? • What is the most common error? Analyzed Data • The most common error was the single eye capture of the right eye • The most common eye to have problems capturing was the right eye with close to a 5:1 ratio • The data showed that 50 out of 97 users required the whole 25 attempts to obtain acceptable results Real World Relevance • Can improve efficiency (in terms of error) of passengers in airports • Can provide more accurate identifications, thus reducing time spent on interacting with the iris scanner • Can provide secure and convenient ways to enter secure locations • With reduced errors, throughput in airports could be increased, pushing people in and out of airports faster and easier Data was acquired from a large scale iris data conducted by BSPA labs. The Iris scan confirmation tracker is how the operators organized their results. Findbiometrics.com Tarrantcounty.com Iris scan confirmation tracker
