Attendance by face recognition

In the period, the teacher's own phone recognises the class, one by one or in a class photo. It ticks them present for the teacher to check. Only with a parent's consent, enrolled by the office, and no photo is kept.

Built; its tests are written and not yet run, and it has not yet run on a real phone. The Campus app is not in the app stores yet. We try it with you in one class before go-live.

Why it matters

Calling 40 names takes the first five minutes of every period, and a tired teacher still ticks a child who left after lunch. The teacher's own phone does the roll call in a minute, from one photo of the class or each child looking at the phone. The teacher stays in charge: the phone only ticks, and the teacher checks and saves. Parents decide for their child in the Campus app or on paper, the office enrols the face, and no photo is ever kept. A school can start with one class and keep the usual register for everyone else.

The problem it solves

  • The roll call takes five minutes of every period, eight times a day.
  • A child who left after lunch is still ticked present because the teacher marked from memory.
  • Parents worry about a school keeping photos of their children on a server.
  • Face devices on the wall cost money, need wiring, and say nothing about a single period.

How it works

  1. The school publishes the consent notice. Parents give consent for their child in the Campus app, or sign the paper form that the office records.
  2. The office enrols each child with consent on the staff phone: three to five photos, straight and slightly to each side, with a blink. Only a list of numbers made from the face is kept.
  3. In the period, the teacher opens the register. The card says how many students can be recognised, for example 24 of 32.
  4. By face: each child looks at the phone and blinks, the name appears with Recognised, and the next child steps up.
  5. Class photo: the teacher takes one photo of the whole class with the back camera, up to three for a big room. Each face is compared with this class only.
  6. The recognised students are ticked present. The teacher checks the list, unticks a wrong name, marks the rest, and saves the register as always.
  7. When the teacher leaves the register, the phone forgets the class's faces.

Everything it does

Consent

  • Nobody is enrolled without consent
  • A student under 18 is a minor: the father, mother or guardian decides, in the app or on paper
  • A student without a birth date counts as a minor unless the office ticks Consents Themself
  • Paper consent: Record Paper Consent on the student's Face Recognition tab, with the notice version and the scan of the signed form
  • Consent status: Given, Not given, Asked or Withdrawn, with who gave it
  • Saying no changes nothing else: the teacher takes that child's attendance as before

Enrolling

  • Only by the Face Recognition Office on the staff view of the app, never in the browser, and never their own face
  • Three to five photos with a blink; a photo is refused when too dark, too far or with two faces
  • A warning when the face looks like a student already enrolled, such as a twin
  • Enrol again when a young child's look has changed a lot

Taking attendance

  • Only for today's open periods of the teacher's own timetable
  • By face: one child at a time, with a blink seen within 3 seconds
  • Class photo: no blink needed, the teacher is in the room; up to three photos, a child found twice counts once
  • The result: Found in the photos with the match per cent, Not found, and Faces not recognised
  • Too small, dark or blurred faces are not used
  • Mark the not recognised absent in one tap, or one by one
  • The register line shows Seen by Face; the back office has a Seen by Face filter
  • A face never marks a child absent, and never saves the register on its own

What is kept

  • Kept: the face template (a list of 128 numbers), the consent with its notice version, and a log of each recognition
  • Not kept: any photo, not even the class photo; photos stay in the phone's memory only while they are compared
  • Nobody can see or download a template, not even the administrator
  • The phone finds faces with an on-device library; the picture never leaves the phone

Teachers' phones

  • Each teacher's own phone becomes a face device the first time it is used, one per teacher and school
  • It holds only the faces of the class being taken, only while that period is open
  • Block a lost phone in Attendances > Face Attendance Phones: it stops at once and wipes the faces at its next contact
  • A phone that has not synced for 7 days deletes the faces it holds

Withdrawing and leaving

  • A parent withdraws in the app at any time; the face is deleted at once
  • Remove Face Data deletes the face and keeps the consent, before enrolling again
  • When a student leaves and is archived, the consent ends and the face is deleted, unless another SmartMy product still holds a consent
  • Delete Unused Faces after a number of months: off to start with

Questions

Does the school keep photos of our children?

No. Photos stay in the phone's memory only while the face is compared, then they are dropped. What is kept is a list of 128 numbers made from the face, which nobody can view or download.

What if a parent says no?

Nothing changes for that child. The teacher marks them by hand in the same register. Consent can be given or withdrawn at any time in the app.

Can a face mark a child absent?

No. A face only ticks a child present. The teacher checks the list, marks the rest and saves, and the saved register is the attendance.

Do we need to buy face devices?

No. Each teacher's own phone with the Campus app is the device, and only for the class being taken.

Will it work in a class of 45?

Take up to three photos, one part of the room each. Children in the back rows of a big room may need a photo from closer. Try it in your own classroom first.

What if a teacher loses the phone?

The office blocks it under Face Attendance Phones. It stops at once and wipes the faces at its next contact, and it holds only one class's faces anyway.
