Classification: CPC G  H | IPC G  H

Claim 28:
29. A non-transitory computer-readable medium having contents which configure processing circuitry of a sensing-device chip to perform a method, the method comprising:
processing sensor-session-authorization requests; and
processing 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 in clear text to the host processor; 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, using encryption circuitry integrated into the sensing-device chip, an encrypted message to the remote server 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, using the encryption circuitry integrated into the sensing-device chip, the encrypted response to the initiated remote-server processing, wherein the encrypted communications are transmitted between the sensing-device chip and the remote server via the application executing on the host processor.
