SECURE SENSOR DATA TRANSPORT AND PROCESSING

摘要

The present disclosure is directed to secure sensor data transport and processing. End-to-end security may prevent attackers from altering data during the sensor-based security procedure. For example, following sensor data capture execution in a device may be temporarily suspended. During the suspension of execution, sensor interface circuitry in the device may copy the sensor data from a memory location associated with the sensor to a trusted execution environment (TEE) within the device. The TEE may provide a secure location in which the sensor data may be processed and a determination may be made as to whether to grant access to the secure resources. The TEE may comprise, for example, match circuitry to compare the sensor data to previously captured sensor data for users that are allowed to access the secured resources and output circuitry to grant access to the secured resources or to perform activities associated with a security exception.

主权项

1. A device including sensor-based security, comprising:
secured resources; sensor circuitry to generate sensor data; memory circuitry including at least a trusted execution environment having access control circuitry therein to control access to the secured resources based on the sensor data; and processing circuitry to cause execution in the device to be temporarily suspended and transfer the sensor data from a memory location in the memory circuitry associated with the at least one sensor to a memory location within the trusted execution environment during the temporary suspension.
