Why do we have both age verification and age estimation? And how do we overcome the restrictions that force us to choose one over the other?
Why age verification?
As I’ve mentioned before, there are certain products and services that are ONLY provided to people who have attained a certain age. These include alcohol, tobacco, firearms, cannabis, driver’s licenses, gambling, “mature” adult content, and car rentals.
There’s also social media access, which I’ll get to in a minute.
So how do you know that someone purchasing one of these controlled products or services has attained the required age?
One way is to ask the purchaser to provide their government identification (driver’s license, passport, whatever) with their birthdate to prove their age.
This is known as age verification. Provided that the ID was issued by a legitimate government authority, and provided that the ID is not fraudulent, this ID provides ironclad assurance that you are 18 years old or 21 years old or whatever the requirement is.
But let’s return to social media.
Why age estimation?
If you’re Australian, sit down for a moment before I share the following fact.
There are jurisdictions in the world that allow kids as young as 13 years old to access social media.
However, these wild uncontrolled jurisdictions face a problem when trying to determine the ages of their social media users. As I noted almost two years ago:
How many 13 year olds do you know that have driver’s licenses? Probably none.
How many 13 year olds do you know that have government-issued REAL IDs? Probably very few.
How many 13 year olds do you know that have passports? Maybe a few more (especially after 9/11), but not that many.
So how can you figure out whether Bobby or Julie is old enough to open that social media account?
One way to do so is by using a technique called age estimation, which looks at facial features and classifies people by their estimated ages.
The only problem is that while age verification is accurate (assuming the ID is legitimate), age estimation is not:
So if a minor does not have a government ID, and the social media firm has to use age estimation to determine a minor’s age for purposes of the New York Child Data Protection Act, the following two scenarios are possible:
An 11 year old may be incorrectly allowed to give informed consent for purposes of the Act.
A 14 year old may be incorrectly denied the ability to give informed consent for purposes of the Act.
So what do you do?
How to perform underage age verification
Biometric Update points out that there is an free alternative for underage people ages 13-15 in the United Kingdom—the CitizenCard. These cards are issued in four categories:
- ’18+’ for adults
- ’16-17′ for those aged 16 to 17
- ’13-15′ for children aged 13 to 15
- ‘Under 13’ for younger children
“OK,” you may say, “but so what? Anybody can print a card that says anything they want, like Alabama’s John Wahl did. Why should anyone accept the CitizenCard?”
Well…people, um, trust it.
CitizenCard is the only non-profit, UK-wide issuer of police-approved proof of age & ID cards….
CitizenCard was founded in 1999 and is governed by representatives from the National Lottery operator Allwyn, the Co-op, Ladbrokes & Coral owner Entain and the TMA.
CitizenCard…is the longest-established and the largest issuer of Home Office-endorsed PASS-hologram ID cards in the UK with more than 2.5 million issued.
[CitizenCard] is audited by members of the Age Check Certification Scheme on behalf of PASS to ensure that the highest standards of UK data protection, privacy and security are upheld and rigorous identity verification is carried out.
So one could argue that you don’t need age estimation in the UK, because there is a well-established way to VERIFY ages in the UK.
However, there are other benefits to age estimation, including the fact that estimation is frictionless and doesn’t require you to pull out a card (or a smartphone) at all.
