摘要： A method of providing an authenticator for an event includes capturing first information of the event, obtaining a first distillation of the first information of the event. The method also includes digitally signing the first distillation of the information of the event to provide a digitally signed first distillation, and providing the digitally signed first distillation during the event for embedding into the event. The method may include obtaining a recording of the event including a digital signature and a purported first distillation, generating a second distillation of information from the second recording, authenticating the purported first distillation of information utilizing a public key associated with the private key utilized to create the digital signature, and conducting a comparison of the second distillation of the event to the purported first distillation.
