Abstract: In one embodiment, a method for controlling access to media content includes defining a viewing profile for at least one viewing user according to a multiplicity of attributes associated with the media content, assigning allowable limits to the multiplicity of attributes in the viewing profile, where each of the allowable limits indicates a rating limit for one of the multiplicity of attributes, receiving attribute ratings associated with a media content item, where each of the attribute ratings is associated with one of the multiplicity of attributes, determining viewing permissibility for the media content item by the at least one viewing user by comparing the attribute ratings with the allowable limits, and based on the viewing permissibility, allowing or disallowing the at least one viewing user to view the media content item.
