Systems and methods for enforcing access-control policies

A system for enforcing access-control policies, the system comprising:

• at least one memory device that stores one or more computer-readable instructions;
• and
• a computing device comprising at least one hardware processor that executes the one or more computer-readable instructions to:
• identify, by a computing device, streaming content that is being transmitted from a media server to a media playback system;
• determine, by the computing device, that a supervised user is within exposure range of the media playback system, and thereby determining that the supervised user is within exposure range of the streaming content;
• receive, by the computing device, a sample of the content from a sampling system that:
• is within the exposure range of the media playback system;
• is physically separated from the media playback system;
• and
• samples the content being transmitted from the media server to the media playback system;
• identify, by the computing device, an access-control policy that defines a content-access restriction for the supervised user;
• determine, based on an analysis of the sample of the content by the computing device, that the access-control policy applies to the content;
• and
• in response to determining that the access-control policy applies to the content, enforce the access-control policy by applying the content-access restriction to the streaming content.

A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• identify, by the computing device, streaming content that is being transmitted from a media server to a media playback system;
• determine, by the computing device, that a supervised user is within exposure range of the media playback system, and thereby determine that the supervised user is within exposure range of the streaming content;
• receive, by the computing device, a sample of the content from a sampling system that:
• is within the exposure range of the media playback system;
• is physically separated from the media playback system;
• and
• samples the content being transmitted from the media server to the media playback system;
• identify, by the computing device, an access-control policy that defines a content-access restriction for the supervised user;
• determine, based on an analysis of the sample of the content by the computing device, that the access-control policy applies to the content;
• and
• in response to determining that the access-control policy applies to the content, enforce the access-control policy by applying the content-access restriction to the streaming content.
