The Cybersecurity Management of Incontrovertible Information

Incontrovertible facts (statements whose truth is certain and can't be subverted) can be transferred securely to a trusted server which can then be used by a network of clients to independently and conveniently validate them, without access to their original source. Certnet (Fact Certification Network) provides such a service. The proposed protocol is based on securely capturing the media (photo or video) in a client's mobile device using the mobile device's security hardware as a remote attestation mechanism which ensures the certainty of the fact. The protocol utilises hardware security features like Apple's SEP to provide the remote attestation concerning the client to the server.
