Airport biometrics are expected to generate $1.3 billion in revenue in the next five years, largely in eGates and kiosks, according to a recent report from Acuity Market Research.

The importance of true liveness detection for authentication can become lost in the noise. Acuity Market Intelligence Principle Researcher Maxine Most has noted that, “One of the main challenges ahead is educating markets about what constitutes the integrity of a biometric system, including how to apply best practices for liveness detection.”

Yesterday’s news that United Kingdom ePassport gates will open to travelers from outside Europe for the first time will be welcomed by regular visitors to the country, including nearly four million from the United States.

According to Acuity’s principal analyst, Maxine Most, “one of the main challenges ahead is educating markets about what constitutes the integrity of a biometric system, including how to apply best practices for liveness detection.” The firm said in its September 2017 financial services whitepaper that liveness detection is a critical component of a secure, well-architected biometric solution, and one of the most important countermeasures to biometric spoofing and presentation attacks.

A promising technology is rapidly gaining adherents, a trend with ramifications for business and cyber security. Last year, market analyst of C. Maxine Most of Acuity Market Intelligence predicted 2017 would be a “breakout year” for behavioral biometrics.
