Abstract: Techniques for operating a computer system for a vehicle are provided. An example method according to these techniques includes observing usage of at least one component of the computer system by an application to generate an application usage log for the application, deriving behavior vectors from the application usage log, determining whether the application is a distracting application by comparing the behavior vectors to one or more application safety rules, and limiting execution of the application responsive to determining that the application is a distracting application and based on status information associated with the vehicle.

Abstract: Techniques for operating a voice-activated computing device are provided. These techniques can be used to prevent voice-based attacks on such devices. An example method according to these techniques includes receiving audio content comprising a voice command, monitoring electromagnetic (EM) emissions using an EM detector of the voice-activated computing device, determining whether the audio content comprising the voice command was generated electronically or was issued by a human user based on the EM emissions detected while receiving the audio content comprising the voice command, and preventing the voice command from being executed by the voice-activated computing device responsive to determining that the voice command was generated electronically.
