What can an iOS app do?


  • Get full access to the front and back camera of an iPhone/iPad any time your app is running in the foreground
  • Use the front and the back camera to know what your user is doing right now and where the user is located based on image data
  • Upload random frames of the video stream to your web service, and run a proper face recognition software, which enables you to
    • Find existing photos of the person on the internet
    • Learn how the user looks like and create a 3d model of the user’s face
  • Live stream their camera onto the internet (e.g. while they sit on the toilet), with the recent innovation around faster internet connections, faster processors and more efficient video codecs it’s hard to detect for the average user
  • Estimate the mood of the user based on what you show in your app (e.g. news feed of your app)
  • Recording stunning video material from bathrooms around the world, using both the front and the back camera, while the user scrolls through a social feed or plays a game
  • Using the new built-in iOS 11 Vision framework, every developer can very easily parse facial features in real-time like the eyes, mouth, and the face frame


Once you grant an app access to your camera, it can

  • access both the front and the back camera
  • record you at any time the app is in the foreground
  • take pictures and videos without telling you
  • upload the pictures/videos it takes immediately
  • run real-time face recognition to detect facial features or expressions

All without indicating that your phone is recording you and your surrounding, no LEDs, no light or any other kind of indication.

It’s interesting that many people cover their camera, including Mark Zuckerberg.
