Abstract: Example processes may include the following operations. Confidence scores may be obtained for different components used to determine an estimate. The confidence scores may be weighted to produce weighted confidence scores. A confidence index may be produced for the estimate based, at least in part, on a combination of the weighted confidence scores. The confidence index may correspond to a reliability of the estimate. Data may be generated that is used to render a graphical user interface (GUI) on a display screen of a computing system. The GUI may display the estimate and the confidence index for the estimate, and the GUI may highlight the estimate graphically. Computer-generated graphics that highlight the estimate on the GUI may be based on the confidence index. The data may be output to render the GUI on the display screen of the computing system.

Abstract: Techniques are presented herein that validate integrity of a computing device. A command to a first processor of a security module of the computing device is received through an interface unit of the security module on a communication channel external to the computing device. A configuration of the security module cannot be changed by a second processor of the computing device which executes an operating system and at least one application on the computing device. In response to receiving the command, one or more memory devices of the computing device are directly accessed by the first processor independent from the second processor to validate integrity of the computing device.
