Abstract: Methods, systems, and apparatus for managing labeling privileges. In one aspect, a method includes receiving label data defining a label to be associated with an image of a first user in a photograph, the first user identified by a first user identifier and the label data associated with a submitting user identifier; accessing data defining labeling privileges for the first user identifier, the labeling privileges being for second users identified by respective second user identifiers, and the labeling privileges defining, for each second user, a labeling privilege for the second user to label an image of the first user in a photograph; determining whether the submitting user identifier is included in the second user identifiers; in response to determining that the submitting user identifier is included in the second user identifiers: determining the labeling privileges for the user identified by the submitting user identifier, and processing the label accordingly.
