Abstract: A sensing system including in-ground sensors not requiring battery power. A thermoelectric generator sensor rod includes an upper thermal contact and a lower thermal contact at or near its two ends. When the thermoelectric generator sensor rod is buried in the ground with one end buried more deeply than the other, a temperature gradient in the soil produces a temperature difference between the upper thermal contact and the lower thermal contact. The upper thermal contact and the lower thermal contact are thermally connected to a thermoelectric generator, e.g., by heat pipes or thermally conductive rods. Electrical power generated by the thermoelectric generator powers sensors for monitoring conditions in the ground, and circuitry for transmitting sensor data to a central data processing system.

Abstract: Embodiments regard determining provenance of digital content. A method of determining the provenance of digital content can include receiving, at processing circuitry, edited digital content and data indicating an entity that edited source digital content to generate the edited digital content, the source digital content, and a destination of the edited digital content, generating, by the processing circuitry, additional data detailing an edit history of the edited digital content, the additional data indicating the entity, an edit identification uniquely identifying the additional data in a ledger, the source digital content, and the destination of the edited digital content, and generating a request to cause the additional data to be stored in the ledger, the ledger operable to be queried so that a user can determine an authenticity of the edited digital content based on the additional data of an edit chain returned in response to a query.
