Face similarity tells you whether the person in a photo you hold is the person who has been passing this account’s HumanChecks. You bring the photo, usually the selfie or photo ID from your own KYC, and we compare it with the face from each check. It answers something a single check doesn’t: whether the account is still with the person who opened it.
Face similarity is in early access and is being turned on one workspace at a time. If a person’s profile has no Face similarity card, it isn’t on for your workspace yet.

Run an assessment

Anyone on your team can run one.
1

Open the person

Open the person from Activity. The Face similarity card sits under the profile tabs. Select Assess similarity.
2

Add up to two photos

Add a photo of them, a photo of their ID, or one of each. Select Add a photo to pick a file, drag one onto it, or paste one with ⌘V or Ctrl+V. Use a JPEG or PNG. Large photos are resized in your browser before they’re sent, so the 5 MB limit rarely comes into play.
3

Select Run assessment

It usually takes a few seconds, and occasionally up to 20. The result opens in the same panel.
For each photo, we work out what it is: a photo of the person, a passport, a driver’s license or another ID document. We check that it shows one clear face, then compare that face with the face from every HumanCheck this person completed with you.

​
Read the result

The headline answers for the whole account. A different person since takes priority over the others, because when the face has changed, the real answer is in the list of checks. The percentage is how similar two faces are. It isn’t the chance that they’re the same person.

​
Your references

Each photo you added gets a row with what we read it as (Photo, Passport, Driver’s license or ID document), its file name, its match percentage and a verdict: Match, Possible, No match or No read. With two photos, a line underneath says whether they show the same person as each other. If they don’t, check you attached the right document. When a photo of the person and their ID both match, the result is marked Document-backed. We tell an ID from a selfie by the text printed on it. Document-backed means your two photos agree with each other and with the checks. It doesn’t mean we checked the document is genuine, or who it names. If none of your photos read as an ID, the result offers to add one. Add photo puts their ID in as a second photo. Swap photo replaces your second photo when neither read as an ID. Either way, the assessment runs again straight away.

​
HumanChecks

This is every check we compared against, newest first. Each row has the date and time, the verification it ran under, whether it passed, its trust score, and the match percentage and verdict for your photo. A check done by someone else’s face is marked a different face. The list includes every check that proved this person’s email or phone with you, whoever was in front of the camera that day. That is how a change of hands shows up. When you added two photos, the list scores the photo of the person, or the other photo if that one couldn’t be read.

​
Find an assessment again

Once someone has been assessed, the card on their profile shows the latest verdict, how many checks it matched (for example, matched 3 of 3 HumanChecks) and when it ran. View assessment reopens it, and Assess again starts a new one. Every past assessment is on the person’s History tab too, in a Face similarity checks card, newest first. Five show at a time, with a button to load the next five, and each opens as a read-only record. A record can’t be re-scored, because the photos weren’t kept. To compare again, run a new assessment.

​
What we keep, and whose checks you see

We don’t keep the photos you upload, as images or as face data. They’re compared and discarded while the assessment runs. What we keep is the result: the verdicts, the percentages, what each photo read as, and the file name you uploaded it under, so the history can tell you which photo was which. Each assessment is saved to the person’s record, which is where the History tab reads it from. You only ever compare against your own company’s checks on that person. If they haven’t completed a HumanCheck with you, the panel says Nothing to compare yet. If a photo resembles someone else your company has verified, we note that on our side. It isn’t shown in the dashboard. Running an assessment doesn’t change the person’s trust score or the result of any check. Next: Exporting users
