Abstract: Described is a technology by which a transient storage device or secure execution environment-based (e.g., including an embedded processor) device validates a host computer system. The device compares hashes of host system data against valid hashes maintained in protected storage of the device. The host data may be a file, data block, and/or memory contents. The device takes action when the host system data does not match the information in protected storage, such as to log information about the mismatch and/or provide an indication of validation failure, e.g., via an LED and/or display screen output. Further, the comparison may be part of a boot process validation, and the action may prevent the boot process from continuing, or replace an invalid file. Alternatively, the validation may take place at anytime.

Abstract: A system and method for providing a power state alter signal to a device based upon a position signal corresponding to the mobile device is disclosed. The technology initially accesses a position based rule. The position based rule is then compared to a position signal. A power alerting signal is provided when the position based rule correlates with the position signal.
