Abstract
A content license associated with unencrypted digital content is generated, the content license including both an identifier of the unencrypted digital content and a content policy. At a user device, a determination is made as to whether the content license corresponds to particular unencrypted digital content. Use of the particular unencrypted digital content by the computing device is permitted in accordance with the content policy if the content license corresponds to the particular unencrypted digital content. However, use of the particular unencrypted digital content by the computing device based on the content license is prohibited if the content license does not correspond to the particular unencrypted digital content.
