Face Scans to Estimate Our Age: Harmful and Creepy AF

Government must stop restricting website access with laws requiring age verification.

Some advocates of these censorship schemes argue we can nerd our way out of the many harms they cause to speech, equity, privacy, and infosec. Their silver bullet? “Age estimation” technology that scans our faces, applies an algorithm, and guesses how old we are – before letting us access online content and opportunities to communicate with others. But when confronted with age estimation face scans, many people will refrain from accessing restricted websites, even when they have a legal right to use them. Why?

Because quite simply, age estimation face scans are creepy AF – and harmful. First, age estimation is inaccurate and discriminatory. Second, its underlying technology can be used to try to estimate our other demographics, like ethnicity and gender, as well as our names. Third, law enforcement wants to use its underlying technology to guess our emotions and honesty, which in the hands of jumpy officers is likely to endanger innocent people. Fourth, age estimation face scans create privacy and infosec threats for the people scanned. In short, government should be restraining this hazardous technology, not normalizing it through age verification mandates.

Error and discrimination

Age estimation is often inaccurate. It’s in the name: age estimation. That means these face scans will regularly mistake adults for adolescents, and wrongfully deny them access to restricted websites. By the way, it will also sometimes mistake adolescents for adults.

Age estimation also is discriminatory. Studies show face scans are more likely to err in estimating the age of people of color and women. Which means that as a tool of age verification, these face scans will have an unfair disparate impact.

Estimating our identity and demographics

Age estimation is a tech sibling of face identification and the estimation of other demographics. To users, all face scans look the same and we shouldn’t allow them to become a normal part of the internet. When we submit to a face scan to estimate our age, a less scrupulous company could flip a switch and use the same face scan, plus a slightly different algorithm, to guess our name or other demographics.

Some companies are in both the age estimation business and the face identification business.

Other developers claim they can use age estimation’s underlying technology – application of an algorithm to a face scan – to estimate our gender (like these venders) and our ethnicity (like these venders). But these scans are likely to misidentify the many people whose faces do not conform to gender and ethnic averages (such as transgender
