Abstract
Systems and methods restrict content inserted into information resources. A computing device can identify a content element included in an information resource. The computing device can identify a bit stream corresponding to the content element included in the information resource. The computing device can hash the identified bit stream to generate an element identifier corresponding to the content element. The computing device can access a restricted content database using the element identifier. The computing device can modify, responsive to finding the element identifier in the restricted content database, the presentation of the content element on the information resource in accordance with the content restriction policy.
