Facial Recognition Search
What facial recognition search engines like PimEyes actually do, why regulators have taken action against them, and how to check your own exposure and opt out.
This page is a guide, not a search tool. We don't scan the web for photos of anyone, and we never will — that capability is used to identify and stalk real people without consent. Every tool on this site measures a single photo's geometry locally in your browser and never searches for or compares you to anyone else.
What Facial Recognition Search Engines Actually Do
Services like PimEyes, FaceCheck.ID, and Eyematch.ai all work roughly the same way
The web gets crawled and indexed
Facial recognition search services scan large portions of the public internet — social media, news sites, blogs, forums — and build a searchable index of every face that appears.
Your uploaded photo becomes a "faceprint"
When you upload a photo, the service converts the face into a mathematical representation (a biometric embedding) it can compare against everything already in its index.
Matches are returned — often to strangers
The service shows photos it judges to be the same person, each linked to the site it came from — potentially revealing social accounts, locations, or other details the uploader didn't already have.
Accuracy and consent are the open questions
False matches are common, and the person in the indexed photos was rarely asked for consent — which is exactly why these services face legal challenges in multiple countries.
This is a fundamentally different process from the tools on this site. A face-shape or symmetry analysis reads the landmarks in the one photo you upload and reports a result about that photo alone — nothing is indexed, searched, or compared against anyone else.
The Privacy Concerns
Regulators, privacy advocates, and anti-stalking organizations have all raised the same core issues
Consent and biometric data
A face is biometric data, and processing it typically requires a clear legal basis. Poland's UODO and France's CNIL have both taken formal action against PimEyes over exactly this — indexing faces without consent.
Stalking and harassment risk
The same lookup that helps you find your own exposure also lets a stranger identify someone from a single photo. Anti-stalking advocates have specifically flagged this as a serious, growing risk.
Accuracy and false matches
Facial recognition systems have documented accuracy disparities across skin tone, age, and gender. A confident-looking "match" can simply be the wrong person.
How to Check Your Exposure and Opt Out
A practical, legitimate way to manage your own exposure — not anyone else's
1. Search for yourself
Most facial recognition search services let you run a search using your own photo — showing you exactly what a stranger searching your face would see.
2. Submit an opt-out request
Services like PimEyes publish a removal/opt-out form, usually linked from their privacy policy. You verify your identity and list the indexed images to remove — expect to repeat this periodically.
3. Reduce what's public
Private social accounts, asking others not to publicly tag you, and non-identifying public profile photos all reduce how much new material these services can index.
4. Know your legal options
GDPR/UK GDPR gives an erasure right for biometric data in many cases. In the US, Illinois's BIPA is the strongest state protection. If you suspect stalking specifically, that's a matter for law enforcement.
What This Site Does Instead
Every analysis tool on this site — the face shape detector, symmetry test, golden ratio calculator, and others — processes a single photo you choose to upload, entirely on your own device using Google's open-source MediaPipe model. Nothing is ever sent to a server, indexed, or compared against a database of other people.
That is a deliberate, structural difference from facial recognition search engines, not just a policy statement. There is no index for your photo to join, and no mechanism by which a stranger could search for you using this site.
Frequently Asked Questions
What is facial recognition search?
Facial recognition search refers to services like PimEyes, FaceCheck.ID, and Eyematch.ai that let someone upload a photo of a face and search the public internet for other photos of that same person — scanning social media, news sites, and more. It is different from face-shape or symmetry tools, which only measure the geometry of a single photo you upload and never search the web or compare you to anyone else.
Is facial recognition search legal?
It depends heavily on jurisdiction. In the EU, Poland's UODO and France's CNIL have both taken enforcement action against PimEyes for processing biometric data without a valid legal basis. In the US, Illinois's Biometric Information Privacy Act (BIPA) is among the strictest state laws and has been the basis for major lawsuits over facial recognition. Using these tools to identify specific people — especially without their knowledge — can also raise separate stalking and harassment concerns regardless of a platform's terms of service.
How do I find out if my photos are indexed?
The most direct way is to search for yourself using the service in question — most facial recognition search tools, including PimEyes, let you run a search of your own face. This is a legitimate, privacy-protective use of these tools — checking your own exposure, not searching for other people.
How do I opt out of PimEyes or similar services?
PimEyes offers an opt-out form to request removal of photos matched to your face — you typically verify your identity and list the specific images to remove. Other services have similar processes, usually in their privacy policy or a dedicated removal-request page. Removal only affects that one service's index, so recurring requests may be needed as new photos get indexed.
Does this site offer facial recognition search?
No. Every tool on this site analyzes the geometry of a single uploaded photo entirely in your browser — no photo is ever uploaded to a server, searched against the internet, or compared to a database of other people's faces. That is fundamentally different from facial recognition search engines, which exist specifically to find and link photos of the same person across the web. We do not build or offer that capability.
What is the difference between facial recognition and face detection?
Face detection simply locates a face within an image — "is there a face here, and where." Facial recognition goes further, generating a biometric signature that can be matched against other faces. The tools on this site use face detection and landmark mapping to measure proportions — they do not generate an identity-matching signature or compare your face to anyone else's.
