Methods, systems, and media for controlling access to content

A system for controlling access to content, the system comprising:

• a memory;
• and
• a hardware processor that, when executing computer-executable instructions stored in the memory, is configured to:
• determine, for a first container item, that a first access list is associated with the first container item and that a content item has been embedded within the first container item, wherein the first access list indicates users that are authorized to access the first container item;
• determine, for the content item embedded within the first container item, that a second access list is associated with the content item, wherein the second access list indicates users that are authorized to access the content item;
• determine that the user that are authorized to access the first container item in the first access list are different than the users that are authorized to access the content item embedded within the first container item;
• modify the first access list to filter out users from the first access list that are not included in the second access list;
• and
• store the modified first access list such that the first access list is accessible to a host of the first container item to verify that a requesting user is authorized to access the first container item.

A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for controlling access to content, the method comprising:

• determining, for a first container item, that a first access list is associated with the first container item and that a content item has been embedded within the first container item, wherein the first access list indicates users that are authorized to access the first container item;
• determining, for the content item embedded within the first container item, that a second access list is associated with the content item, wherein the second access list indicates users that are authorized to access the content item;
• determining that the user that are authorized to access the first container item in the first access list are different than the users that are authorized to access the content item embedded within the first container item;
• modifying the first access list to filter out users from the first access list that are not included in the second access list;
• and
• storing the modified first access list such that the first access list is accessible to a host of the first container item to verify that a requesting user is authorized to access the first container item.
