Cybersecurity of a Fact Certification Network

A system of protocols is defined which enables suitably equipped systems or devices to record validated "facts" in a network of servers in such a way that only facts which are genuinely true can be validated by the network. The servers or devices using this network make use of remote attestation to provide this secure and integrated network, which is called, henceforth, Certnet (Certification Network). Certnet of this paper can be envisaged, for example, as providing rigorous fact-checking for a news service. Currently any individual trying to capture media evidence (photo or video) has no way to certify their evidence. Certnet will provide this missing certification of evidence, for suitable equipment.
