Abstract:
1. A method of validating a content for use on a network comprising a plurality of nodes configured to communicate a content validity status therebetween, comprising: receiving the content at a node of the network; identifying whether the content is embedded with at least one adjunct; determining whether the at least one adjunct comprises a watermark and whether the at least one adjunct comprises meta data; reviewing each of the watermark and the meta data, where found, to determine whether the content is valid for use on the node; indicating that the content is unauthorized for use on the node where content is not embedded with an adjunct or where a watermark and/or meta data, where found, is not able to render the content valid for use the node; and after identifying whether the content is embedded with at least one adjunct, signaling to all other available or connected nodes on the network that the content is unauthorized for use on any node of the network where the content is unauthorized for use on the node and preventing transfer of the content to the other nodes by signaling to the other nodes that the content is unauthorized.
