<p>If a content consumer trusts a particular signer, then they may be inclined to believe that the information provided in the manifest is authentic. In other words, a preexisting relationship of trust between a signer and a content consumer is the basis of the C2PA trust model. C2PA specifications are designed to provide signals for content consumers to know that the signer is in fact who they say they are and that the manifest is in fact connected to a particular asset.</p>
