Claim 23:
24. A method, comprising:
processing, using processing circuitry integrated into a sensing-device chip, sensor-session-authorization requests; and
processing, using the processing circuitry integrated into the sensing-device chip, sensor-service requests received from an application executing on a host processor, the received sensor-service requests including sensor service requests of a first type and sensor-service requests of a second type, wherein the processing of a received sensor-service request includes:
receiving the sensor-service request in clear text from the host processor;
determining a type of the received sensor-service request;
in response to determining the received sensor-service request is of the first type, generating results information in response to the sensor-service request of the first type based on sensor data generated by sensing circuitry integrated into the sensing-device chip and transmitting the results information to the host processor in clear text; and
in response to determining the received sensor-service request is of the second type:
initiating remote-server processing based on the sensor-service request of the second type, the initiating remote-server processing including generating an encrypted message to the remote server, using encryption circuitry integrated into the sensing-device chip, and transmitting the encrypted message to the remote server via the application executing on the host processor without decrypting of the encrypted message by the host processor; and
generating a response to the sensor-service request of the second type based on an encrypted response to the initiated remote-server processing received from the remote server via the application executing on the host processor, wherein the generating the response to the sensor-service request of the second type includes decrypting the encrypted response to the initiated remote-server processing using the encryption circuitry integrated into the sensing-device chip, wherein the encrypted communications are transmitted between the sensing-device chip and the remote server via the application executing on the host processor.
