Abstract
The present invention extends to methods, systems, and computer program products for validating and supplementing emergency call information removing private information. A probability that an emergency call originated from a location is derived from features of a normalized signal version of the emergency call. An additional normalized signal is accessed within a specified distance of the location. The location is validated from features of the additional signal. An event is detected from the features of the normalized signal version of the emergency call based on the validated location. The validated location is associated with an obtained event truthfulness probability for the event. The event is sent to a Public Safety Answering Point (PSAP). A privacy infrastructure spans signal ingestion, event detection, and event notification and protects the integrity of private information.
