Content filtering for information centric networks

A method provides for marking classifications of content objects at a content marking node in a content centric networking (CCN) network. The content marking node has a network interface with a network that is separately administered from the CCN network. The method includes receiving a content object on the network interface, checking whether the content object is authentic and there is a pending interest for the content object, and sending a request to a content marking service to obtain categories for the content object using a name of the content object. The method further includes receiving a response from the content marking service with the categories for the content object, and adding a category field to the content object, the category field including the categories.
