According to The US Customs and Border Protection program, a facial recognition and face matching system is used at departure gates in 17 airports in US, and there’s plans to have the system scan 97% of all outbound international travelers in just two years.
This technology could replace the need to manually check papers and create an automated process. Facial recognition with cameras could eliminate the need to interact with humans. Of course, the most obvious reason to implement a facial recognition/tracking system is for security purposes. This would allow the security team to easily identify all individual of possible threat and track their movements.
Concerns have been risen regarding privacy and error rates. Facial recognition seems to be less accurate among certain traits such as race and ethnicity.
CBP has responded saying that the system is not intended for surveillance, but implemented in compliance with the law, and will only keep photos of US citizens for 12 hours, and non-citizens for 14 days.
Looking forward, CBP plans to continue expanding facial recognition implementation, citing that it is less invasive in privacy than other biometrics such as fingerprints.
Regardless of how people feel about the privacy of this new implementation, it seems it will continue to progress. It will be interesting to see the effects this implementation will bring in the long run.
