Abstract: A method for partially unmasking an object in a video stream comprises: displaying a first video stream in which objects are covered by privacy masks; receiving user input regarding a selection of an object being covered by a privacy mask, wherein the object has a first portion being associated with a first privacy level and a second portion being associated with a second, higher, privacy level; checking that a permission associated with the user input grants access to video data depicting object portions being associated with the first privacy level; giving access to video data depicting the first portion of the object; and displaying a second video stream which differs from the first video stream in that it includes the video data depicting the first portion of the object, while the second portion of the object is still covered by a privacy mask.
