Abstract
Described herein are systems for the production, communication, routing, service, authentication, and consumption of cryptographically authenticable contextual content produced by cryptographically authenticable devices; example implementations of the architecture for a Trusted Contextual Content Device which produces Trusted Contextual Content; and example implementations of the architecture for a Trusted Drone Device which produces Trusted Contextual Content. For example, some of the methods used may include accessing a first set of sensor data from one or more sensors; receiving, a first trusted contextual content that includes a first digital signature; generating a data structure including the first trusted contextual content and data based on the first set of sensor data; signing the data structure using a signing key to generate a second trusted contextual content including a second digital signature; and storing or transmitting the second trusted contextual content.
