The Georgetown Law Center on Privacy and Technology questions the value and legal standing of facial recognition technology that supporters say could make international travel safer and more efficient. The criticism comes as the Biometric Exit technology finds use in eight U.S. airports.

During a hearing with U.S. senators, biometric exit gained a boost when a customs official said the security technology could be deployed in all major U.S. airports within four years. Already, officials have tested biometric exit systems in large airports, and have installed facial recognition technology at major border crossings.

Digital identity company IDEMIA, along with Royal Caribbean Cruises and U.S. customs officials, recently tested a biometric authentication system designed to move passengers through border checkpoints in less time than via manual checks. So far, results are promising, with another test planned for next year—and possible enhancements to follow.

New authentication research from FIDO and Javelin finds that too many businesses and consumers still rely on weak passwords, presenting criminals many juicy targets. But there is hope for better security as mobile commerce and ID continue to rise—and as enterprises recover from breaches and adopt two factor techniques.

The Middle Eastern locale wants to make boarding and immigration more efficient by using smartphones, biometric checks and more data links. But that’s not all. Also in the works is a system through which certain travelers could authenticate themselves during a car ride to the airport.

The name Stephanie Schuckers is almost synonymous with liveness detection in biometrics. But it doesn’t end there. Dr. Schuckers is also a professor at Clarkson University, director of the Center for ID Technology Research, founder of a biometric startup and mentor to an ongoing crop of new biometric scientists. Last year, the startup she founded was acquired by a leading biometric company. This month, she is being honored as a recipient of the 2017 Women in Biometrics Awards.

Biometrics was neither a household term nor a ‘handset technology’ when Frances Zelazny began working with facial recognition two decades ago. During her career she has helped shape the use of biometrics for security, identity and now for payment applications. Throughout, she has advocated for responsible use guidelines and practices, something that has proven essential to the industry’s maturation.
