If you’ve ever wondered what actually happens to your child’s face after you post it, this is a calm walk through it. Sharenting and facial recognition are quietly linked: the everyday act of sharing a child’s photo, and a technology that can turn that face into a searchable, matchable piece of data. The goal here isn’t to frighten you off ever posting. It’s to explain, plainly, what the technology does, what has genuinely been documented, what the law now says, and the small number of habits that keep your child’s face out of systems it was never meant to be in.
What sharenting and facial recognition mean together
Sharenting is the ordinary habit of parents sharing photos and details of their children online. On its own, that’s just love with a camera. (If it’s a new word, start with our guide to what sharenting is and why it matters.)
Facial recognition is the technology that reads a face and turns it into a “faceprint”, a mathematical map of the distances between features that can be matched against other images. Give a system enough clear photos of one face and it can find that same person across the internet, in other people’s photos, in the background of strangers’ posts, years apart.
Put the two together and you get the thing worth understanding: a public photo of your child isn’t just a nice picture. It’s a labelled sample of their face, and their face is the one password they can never change.
How a photo becomes a “faceprint”
It helps to see the mechanism, because it demystifies the fear. A facial-recognition system does three things:
- Detects a face in an image.
- Encodes it into a faceprint (a string of numbers unique to that face’s geometry).
- Matches that faceprint against a database of other faces to find the same person elsewhere.
The uncomfortable part is step three. The bigger and more public the database, the better the matching. And a child photographed from birth is the ideal training subject: the same face, from many angles, over many years, often helpfully captioned with a real name, a birthday, and a hometown. Health experts note that publicly visible photos of children can be used to build exactly these kinds of profiles (Cleveland Clinic).
This isn’t hypothetical: what’s actually been documented
Two well-documented cases move this from “what if” to “what happened”.
Clearview AI. A single company scraped billions of photos from public social media (Facebook, Instagram, YouTube, Venmo) to build a facial-recognition search engine, without asking any of the people in them. Its database has been reported at over 20 billion faces and climbing, and European regulators have pushed back hard: in 2024 the Dutch data authority fined Clearview more than 30 million euros for building “an illegal database” of faces taken from the web (Forbes). If your child’s photo was ever public, this is the category of system it could have fed.
AI training and deepfakes. In June 2024, Human Rights Watch found photos of identifiable children scraped into LAION-5B, one of the large public datasets used to train image AI, captions and all, sometimes with the child’s name and location attached. In some cases, tools trained on that kind of data were then used to generate explicit fakes of real children (Human Rights Watch). Many of those photos had been posted years earlier by parents who imagined a small, friendly audience. (We cover the training-data angle in full in do Meta and Google use your child’s photos to train AI?)
Notice what both cases share: the harm didn’t come from a dramatic hack. It came from photos that were simply public, quietly collected by parties the parents never met.
Why a child’s face is a special case
Adults leave a face trail too, but a child’s is different in three ways, and none of them require panic to take seriously.
- It’s permanent and unchangeable. You can reset a leaked password. You can’t reset a face. A faceprint made from today’s photo still matches the adult that child becomes.
- It starts before consent is even possible. By the time a child could object, a labelled record of their face already exists. Research suggests children today appear in close to a thousand online photos before they turn five (Nominet). That footprint is examined more closely in your child’s digital footprint starts before they can walk.
- It accumulates. One photo is a snapshot. A childhood of photos is a longitudinal dataset: the same face ageing over time, which is exactly what makes recognition more accurate, not less.
What the law says about faces
The legal ground is shifting fast, and mostly in the child’s favour.
- In the EU and UK, the GDPR treats a face used for recognition as biometric data, a special category that gets stronger protection than an ordinary photo. That’s the legal basis regulators have used to fine facial-recognition firms for scraping public images: the face isn’t “just a picture”, it’s sensitive data.
- In the US, there’s no single federal face-privacy law, but Illinois’ Biometric Information Privacy Act (BIPA) has real teeth. Clearview AI settled a lawsuit brought under it, agreeing to limits on who it can sell access to. COPPA separately restricts how online services collect data from under-13s.
- In France, a 2024 law wrote a child’s privacy into parental authority itself, making both parents jointly responsible for protecting their child’s image and letting a judge intervene when they disagree (Bird & Bird).
The direction of travel is unmistakable: a face is increasingly treated as data a child has rights over, not content a parent freely owns.
The calm playbook: keeping your child’s face out of the machine
Here’s the reassuring part. You don’t need to hide your child, blur every photo, or quit sharing. Almost all of the risk above depends on one thing, the face being public, and that’s the single lever you control.
- Share to a circle, not a feed. A facial-recognition scraper can only index what it can reach. A photo shared with a small, named group of people simply isn’t in public view to be collected. This is the biggest lever by far.
- Strip the metadata. Location and camera data ride along invisibly in photo files. Turn off location tagging, and prefer tools that remove metadata automatically before anyone sees the image.
- Drop the labels. Recognition gets far more dangerous when the face comes with a full name, birthday, and hometown. Skip the identifiers even when you do share.
- Close the easy exit. Most photos leak not through hacking but through a screenshot, forwarded on. Tools that block screenshots keep a face inside the circle you chose. (Here’s why we block screenshots on every photo.)
- Blur only if you want to. Emojis over faces, shooting from behind, or cropping to a hand or foot all cut recognition risk, and some parents like them. But they’re a workaround for public sharing. Share privately and you get to keep the actual face, for the actual people who love it.
- Ask relatives and schools to do the same. A tight ship at home doesn’t help if the nursery posts the class photo publicly. A warm, one-time conversation usually settles it.
Where private-by-design tools fit
The honest reason this is hard is that the default tools are built to make faces public: that’s their entire business model. The fix isn’t more vigilance inside a broadcast app. It’s a tool built for the opposite goal, sharing a face inward to a chosen circle instead of outward to an audience and every scraper watching it.
That’s the whole idea behind pouchie: a private space to share your kids’ photos with the specific people who love them. Nothing is public, so there’s no surface for a facial-recognition scraper to find. Photos aren’t used to train AI or sold to data brokers, metadata is stripped before anyone sees the image, and screenshots are blocked so a face can’t quietly slip out of the circle. It’s the same warm sharing you already do, without leaving your child’s face on the open internet.
The takeaway
Sharenting and facial recognition are linked by one word: public. A public photo of a child’s face can be turned into a faceprint, matched across the internet, swept into datasets, and, as documented cases show, misused in ways no parent signed up for. But that same word is the good news, because it points straight at the fix. Keep the face out of public reach, share it inward to the people who were always the point, and your child keeps the one thing they can never change: control over their own face.
