NIST Report Evaluates Performance Of Iris Recognition Software

Identifying people by acquiring pictures of their eyes is becoming easier, according to a new report from the National Institute of Standards and Technology (NIST).

NIST researchers evaluated the performance of iris recognition software from 11 different organizations and found that some techniques produced very rapid results -- though this speed was often at the cost of accuracy.

Iris recognition, a form of biometric identification based on noncontact imaging of the complex texture in an individual's iris, has been purported to be both fast and accurate -- claims that had not been validated until now. The Iris Exchange (IREX) III report is the first public and independent comparison of commercially available algorithms that use iris recognition for the challenging task of finding an individual match within a large database of potential identities. Previous published studies only used single algorithms or considered "one-to-one" verification, in which an individual claims an identity and the software then attempts to confirm whether the claim matches a specific record.

NIST evaluated 92 different iris recognition algorithms from nine private companies and two university labs, all of which submitted software to an open competition held by NIST. The task was to identify individuals from a database of eye images taken from more than 2.2 million people.

"If, for example, you are trying to pick out a fugitive who is trying to cross a national border, you need to know your software can identify that person from among millions of records," said Patrick Grother, a scientist in NIST's Information Access Division. "This ability to pick out a 'needle in a haystack' quickly and accurately is crucial, and we found some algorithms can search a haystack thousands of times larger than others. This is important because often there is no corresponding record, no needle to be found."

Among the results: Accuracy varied substantially across the algorithms the NIST team tested. Success rates ranged between 90 and 99 percent among the algorithms, meaning that no software was perfect, and some produced as many as 10 times more errors than others. Also, the tests found that while some algorithms would be fast enough to run through a dataset equivalent to the size of the entire U.S. population in less than 10 seconds using a typical computer, there could be limitations to their accuracy. A related NIST report showed that accuracy could be improved if operators control image collection more tightly during acquisition, thereby obtaining better quality iris images.

"When combined with the feedback that this study provides to the industry and the use of the iris in combination with other biometrics, the findings will push accuracy toward 100 percent," Grother said. Grother adds that the new findings should be useful to policy makers, who are increasingly incorporating iris recognition in official systems in places as far-flung as India, Mexico and Indonesia, as well as the United States and Canada.

  • The Key to Wellbeing in the Office

    A few years ago, all we saw in the news was the ‘great resignation.’ Now we have another ‘great’ to deal with. According to CBRE, 2023 was the start of the ‘great return’ as office workers returned to their normal offices after working from home. The data shows that two-thirds of all U.S office buildings were more than 90% leased as of Q2 2023. Read Now

  • Failed Cybersecurity Controls Costing U.S. Businesses $30 Billion Yearly

    Panaseer recently released ControlWatch and the Continuous Controls Battle: Panaseer 2025 Security Leaders Report examining the cost of cybersecurity control failures and the impact of growing personal liability for security failings on security leaders. The report analyzes the findings of a survey of 400 security decision makers (SDMs) across the US and UK. It shows that security leaders feel under increasing pressure to provide assurances around cybersecurity, exposing them to greater personal risk – yet many lack the data and resources to accurately report and close cybersecurity gaps.

  • The Business Case for Video Analytics: Understanding the Real ROI

    For security professionals who may be hesitant to invest in video analytics, now's the time to reconsider. In a newly released Omdia report commissioned by BriefCam (now Milestone Systems), the research firm uncovered a compelling story: more than 85% of North American and European organizations that use video analytics achieve a return on investment within just one year. The study, which surveyed 140 end users across multiple industries, demonstrates that security technology is no longer just for security — it's a cross-organizational tool that delivers measurable business value far beyond traditional safety applications.

  • Survey: 54% of Organizations Cite Technical Debt as Top Hurdle to Identity System Modernization

    Modernizing identity systems is proving difficult for organizations due to two key challenges: decades of accumulated Identity and Access Management (IAM) technical debt and the complexity of managing access across multiple identity providers (IDPs). These findings come from the new Strata Identity-commissioned report, State of Multi-Cloud Identity: Insights and Trends for 2025. The report, based on survey data from the Cloud Security Alliance (CSA), highlights trends and challenges in securing cloud environments. The CSA is the world’s leading organization dedicated to defining standards, certifications, and best practices to help ensure a secure cloud computing environment. Read Now
