TSA's facial recognition for air travel sparks privacy outrage

TSA is running a facial recognition trial at airports, which has prompted privacy concerns for politicians. Kurt "CyberGuy" Knutsson explains how it works.

If you're old enough, you might remember when going through airports was a breeze compared to today's enhanced passenger and baggage screening procedures. Back then, you didn't have to worry about full-body scanners, passenger and carry-on luggage checks, or the other airport security protocols that are now in place. It's way different from how things are now.

Get ready for possibly even more security upgrades in the future if the TSA has its way. The Transportation Security Administration is testing out its new facial recognition technology at a number of airports throughout the country. This tech identifies and verifies individuals on their unique features.

However, a few government officials are not happy. They are concerned about the risk to civil liberties, privacy rights, safety and security of biometric data, and racial discrimination. Here's what we know so far.

The way the TSA uses facial recognition is by taking pictures of passengers and comparing them with the passenger's identification. Typically, when going through the security process at a domestic airport, a passenger will hand over their driver's license, and a TSA agent will place the license into a card reader to verify if the ID is real or fake.

With this new process, your ID would still be placed into the card reader, and then the TSA agent would take a picture of your face in real-time. That picture will be processed to see if it matches the picture on your driver's license. The agent will then approve the screening once the picture is verified.

When asked about how the trials were going thus far, the TSA stated, "the TSA has grounded the tests in scientific rigor and early results are promising across all demographics with a small sample, so TSA is expanding the sample size for statistical validity."

The following airports are currently using this facial recognition testing at their security lines.

No, you do not have to participate. According to the TSA, the trial is completely voluntary, and you can refuse to have your photo taken by telling an officer at the Travel Document Checker podium. In my experience, there is no sign or active notice during numerous TSA screenings letting you know it's optional to have your face scanned. The TSA also states that this will not cause the passenger any delay, and they will not face any consequences for not participating.

Once the TSA takes your picture and verifies your identity, the picture only remains in RAM memory, and it is automatically purged as soon as the TSA officer logs off their computer. The computer is also set to log off automatically after not being used for 30 minutes.

The only time your picture will be kept in the system for longer than this period is during a data collection period when the DHS Science and Technology Directorate will encrypt the photo's data for analysis. However, TSA says there are no personally identifying details held within this data, and the department deletes all its encrypted data within 24 months.

U.S. Sens. Jeffrey Merkley, Edward Markey, Cory Booker, Elizabeth Warren and Bernie Sanders have collectively penned a letter to the TSA expressing multiple concerns over this trial.

One main concern is that not many people going into these participating airports are aware of the trial, and TSA officials have not been informing passengers that the trial is voluntary, according to what Senator Merkley says he witnessed when he was at a participating airport. Another worry is that it is unclear how travelers will know that they can "opt-out", and what the consequences for travelers are if they do decide to opt-out.

Their other main concern is the chance of facial recognition technology perpetuating racial bias, as studies have shown that certain racial and ethnic groups, particularly Asian and African American individuals, are more likely to be misidentified by the technology.

And the final big concern is privacy, as it has not been made totally clear if the DHS Science and Technology Directorate will be sharing any data they collect with other government agencies and what exactly they will be doing with that data. All we know is that they are telling us anything they collect will be deleted within 24 months.

Remember, whether the TSA agent at the airport tells you or not, you have the right to refuse to go through the facial recognition technology trial. If the whole idea doesn't sit right with you, simply let the agent know that you will not participate, as they cannot penalize you for not wanting to be part of it.

Does the idea of the TSA having your facial data make you uncomfortable? Do you think this is a good security measure to use in the future? Let us know by commenting below.
