TRUSTED SENSORS
First Claim
Patent Images
1. A sensor system, comprising:
- sensors of a device that generate sensor readings for consumption by an application; and
a trust component of the device that provides trust information which is applied to the sensor readings to create trustworthy readings for communication to the application.

Abstract
Architecture that provides trusted sensors and trusted sensor readings on computing devices such as mobile devices. The architecture utilizes a trustworthy computing technology (e.g., trusted platform module (TPM). In the context of TPM, one implementation requires no additional hardware beyond the TPM and a virtualized environment to provide trusted sensor readings. A second implementation incorporates trusted computing primitives directly into sensors and enhances security using signed sensor readings. Privacy issues arising from the deployment of trusted sensors are also addressed by utilizing protocols.
