Secure exams on lab computers

The desktop app runs a paper in a window that cannot be left, on a machine your institution has enrolled, and sits it with no internet at all if it has to.

What the app adds

  • A window that cannot be left

    Fullscreen, on top, no other tabs or windows. Everything the lock cannot prevent is recorded instead, and the invigilator sees it live.

  • A machine you have enrolled

    A device key kept in the OS credential store signs every request, so an exam can insist on being sat in your lab and nowhere else.

  • No internet required

    Carry a sealed pack in on a stick, sit the paper offline, and upload the results, each attempt signed by the machine that produced it.

Exam machines

Install on each lab machine, then sign in once as an administrator to enrol it. A machine that has not been enrolled can still sit an exam that does not require one. No desktop build has been published yet.

Every file's SHA-256 is in the manifest and in the X-Checksum-SHA256 header of the download. An exam can require a minimum app version, so keep lab machines on the newest build before exam day.

Phones and tablets

The phone app is for results, marking and the register: students checking results, teachers marking on the move. Exams that require the locked-down window are not sat on a phone. The website needs neither app.
