  • receiving, from a device, an image comprising a first person;

    determining, from a machine readable identifier, a first face descriptor associated with the first person, the first face descriptor specifying a first set of facial features associated with the first person;

    detecting a face in the image;

    generating a second face descriptor for the face detected in the image by extracting a second set of facial features for the face detected in the image based on the first set of facial features specified in the first face descriptor;

    determining whether the first person is in the image based on identifying whether the second face descriptor matches the first face descriptor;

    determining metadata information associated with the first face descriptor from the machine readable identifier;

    responsive to identifying that the second face descriptor matches the first face descriptor,determining a spatial location of the first person in the image and an action to be performed on the image, the action specified by the metadata associated with the machine readable identifier; and

    performing the action including adding a portion of the metadata information to the image at a location proximal to or overlapping with the spatial location of the first person in the image; and

    responsive to identifying that the second face descriptor fails to match the first face descriptor, sending a message indicating that the first person associated with the first face descriptor is not in the image.
