Abstract: System and method for securing sensor data in a computer system that includes a host processor and memory that stores an operating system, and an embedded controller coupled to the host processor. The embedded processor receives sensor data for a user from at least one sensor, and encrypts and/or digitally signs the sensor data, thereby generating protected sensor data, or performs pattern recognition on the sensor data, thereby generating user identification data. The embedded processor then sends the protected sensor data or the user identification data to the operating system or another process coupled to the computer system. The protected sensor data or the user identification data are used for secure transmission of the sensor data.
