Classification: CPC G  H | IPC G  H

Claim 0:
1. A system, comprising:
a host processor, which in operation, executes an application that generates sensor-service-authorization requests and sensor-service requests; and
an integrated sensor device integrated into a chip and coupled to the host processor, the integrated sensor device including:
sensing circuitry integrated into the chip, wherein the sensing circuitry, in operation, generates sensor data related to one or more physical conditions;
processing circuitry integrated into the chip and coupled to the sensing circuitry, wherein the processing circuitry, in operation,
receives a sensor-service request in clear text from the host processor;
determines a type of a sensor-service request received from the host processor;
in response to determining the received sensor-service request is of a first type, generates results information in response to the sensor-service request of the first type based on generated sensor data and transmits the results information in clear text to the host processor; and
in response to determining the sensor-service request is of a second type:
initiates remote-server processing based on the sensor-service request of the second type, wherein the initiating comprises sending an encrypted communication from the integrated sensor device to the remote server via the host processor, without decrypting of the encrypted communication by the host processor; and
generates a response to the sensor-service request of the second type based on a response to the initiated remote-server processing; and

encryption circuitry integrated into the chip, wherein the encryption circuitry, in operation, encrypts communications from the integrated sensor device to the remote server and decrypts communications from the remote server to the integrated sensor device, wherein, in operation, the encrypted communications are transmitted between the integrated sensor device and the remote server via the application executing on the host processor.
