Abstract
Embodiments are directed to protection of privacy and data on smart edge devices. An embodiment of an apparatus includes a sensor to produce a stream of sensor data; an analytics mechanism; and a trusted execution environment (TEE) including multiple keys for data security, the apparatus to exchange keys with a host server to establish one or more secure communication channels between the apparatus and a TEE on a host server, process the stream of sensor data utilizing the analytics mechanism to generate metadata, perform encryption and integrity protection of the metadata utilizing a key from the TEE for the sensor, sign the metadata utilizing a private key for the analytics mechanism, and transfer the encrypted and integrity protected metadata and the signature to the host server via the one or more secure communication channels in a manner that prevents privileged users on the host from accessing the data.
