Selfie search and consent layers

Selfie search lets a guest take a selfie and find the photos they appear in at the event. It relies on face recognition, so it never runs on its own: the platform, studio, event owner and guest layers all have to be on. If one is missing, no search takes place.

This article is for the studio team. It explains how to turn the feature on, what the guest sees on screen and when face data is deleted.

What you can do today

• Add the Find with selfie feature per event, and turn it off and on again during the event.
• See the approval layers and the scan status on one card in the panel.
• Guests can give explicit consent and find their own photos with a live selfie.
• Guests can correct matches with This is me and This is not me.
• Guests can withdraw consent in one step with Delete my face data.
• Guests can hide the guest photos they appear in from other guests in an open gallery.

The consent layers

Search works only when every layer below is in place.

The studio agrees on selfie search with the event owner, event by event. Talk to the event owner before you turn the feature on.

Selfie search does not run unless you add it to the event. Do not turn it on without agreeing with the event owner. We advise against using it at events where most guests are children.

Turning the feature on for an event

1. If your account does not have the Find with a selfie scope, request it in the panel under Add scope with Send request. Our team reviews it.
2. When you create a new event, tick Find with selfie in the Features section. On an existing event, open the Settings tab and click Add Find with selfie in the Features row of the Plan and duration card.
3. On the Selfie search card in the Overview tab, check that all three layers are ticked.
4. Upload your professional photos. For the steps, see Uploading professional photos to an event.

Adding the feature uses no credits at opening. Credits are deducted at upload: 1 for each professional photo, and 1 per 3 seconds of professional video. Face scanning of the photos guests upload is not charged separately.

What the guest sees

When the feature is on, the guest page shows a note at sign-in that photo matching is used at the event, and a My photos tab.

1. In the My photos tab the guest reads a short explanation and taps Start.
2. The explicit consent text is shown on a separate screen. The checkbox arrives unticked. By ticking it, the guest states that they have read the text, are over 18 and give explicit consent, then taps Continue.
3. The front camera opens. The guest places their face in the frame. The shot is taken automatically, or the guest can use the Take selfie button.
4. The screen asks the guest to turn their head slightly and takes a second frame.
5. The search runs and the results are listed.

Consent is optional. A guest who does not consent can keep using everything else on the page.

Liveness check

A search cannot be made with a photo picked from the gallery. Only live video from the front camera is accepted, and two frames are taken: one looking straight, one with the head turned slightly. The system checks that the face in both frames belongs to the same person, that the frames are not copies of each other and that the head really turned. If the check fails, the guest tries again.

To prevent abuse, the same guest waits 20 seconds between searches.

Matches: certain and possible

Results come in two parts:

• Certain matches are at the top, with a heading that says in how many photos the guest was found.
• Might be you holds the frames the system is not sure about.

When the guest opens a frame they see two buttons. This is me turns a possible match into a certain one and opens the print and share options for that photo. This is not me removes the frame from the list, and it does not come back in later searches.

Matches cover both the photos guests uploaded and the professional photos. For professional videos, the moment the guest appears is shown as a time on the thumbnail and the video starts from there. As photos still in the queue are scanned, new matches are added automatically. The guest can also start over with Search with a new selfie.

At an event with an open gallery, a guest can tick Hide photos I appear in from the gallery. Other guests then do not see the guest photos that guest appears in; the studio and the uploader still do.

The under-18 rule

People under 18 cannot use selfie search. Without the declaration on the consent screen the search does not start. The rest of the page works the same way for every age.

How face data is stored

• The selfie image is not stored. If the phone supports it, the face vector is computed in the browser and the image does not leave the phone. If not, the frames are processed in memory only and discarded.
• What is stored is a numerical vector derived from the face, and it is kept encrypted.
• The vector is compared only with photos from that event. It is not used at any other event.
• The version of the text under which consent was given is recorded.

Deleting face data

If the studio turns the feature on again, the photos are scanned from the start and no extra credits are charged. Guests have to give a selfie again. For all retention periods, see Privacy, retention and deletion.

The event owner's own pagePlanlaşdırılır

A page where the event owner can turn selfie search off and on by themselves is planned. That page is not open in CollectAsist today. If the event owner asks for it to be turned off, the studio does so with the switch on the Selfie search card.
