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.

Claims

1. A method comprising:

deriving, from features of a normalized signal version of an emergency call signal, a probability that the emergency call signal originated from a location, wherein the normalized signal version is a dimensionally reduced version of the emergency call signal;

accessing an additional normalized signal within a specified distance of the location;

determining that the additional normalized signal includes user information;

removing at least a portion of the user information from the additional normalized signal;

validating the location from features of the additional signal subsequent to removing the at least a portion of the user information;

detecting an event from the features of the normalized signal version of the emergency call signal based on the validated location;

associating the validated location with an obtained event truthfulness probability for the event; and

sending the event to a Public Safety Answering Point (PSAP).

2. The method of claim 1, further comprising:

determining a severity based on characteristics of the normalized signal version of the emergency call signal and the additional normalized signal; and

associating the severity with the event.

3. The method of claim 1, wherein accessing an additional normalized signal comprises accessing the additional normalized signal that includes one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI).

4. The method of claim 1, wherein removing at least a portion of the user information from the additional normalized signal comprises removing one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI) from the additional normalized signal.

5. The method of claim 1, further comprising listening for additional normalized signals in geo cells within the specified distance of the location prior to accessing the additional normalized signal.

6. The method of claim 1, wherein deriving the probability that the emergency call signal originated from the location comprises deriving the location from an audio overlay indicating a location of the emergency call signal.

7. The method of claim 1, wherein sending the event to the PSAP comprises sending the event to the PSAP prior to a carrier network sending phase II data to the PSAP.

8. The method of claim 1, further comprising:

receiving the normalized signal version of the emergency call signal that includes other user information; and

removing at least a portion of the other user information from the normalized signal version of the emergency call signal; and

wherein detecting an event from the features of the normalized signal version of the emergency call signal comprises detecting the event subsequent to removing the at least a portion of the other user information from the normalized signal version of the emergency call signal.

9. The method of claim 8, wherein receiving the normalized signal version of the emergency call signal comprises receiving the normalized signal version of the emergency call signal that includes one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI).

10. The method of claim 8, wherein removing at least a portion of the other user information from the normalized signal version of the emergency call signal comprises removing one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI) from the normalized signal version of an emergency call signal.

11. A system comprising:

a processor;

system memory coupled to the processor and storing instructions configured to cause the processor to;

derive, from features of a normalized signal version of an emergency call signal, a probability that the emergency call signal originated from a location, wherein the normalized signal version is a dimensionally reduced version of the emergency call signal;

access an additional normalized signal within a specified distance of the location;

determine that the additional normalized signal includes user information;

remove at least a portion of the user information from the additional normalized signal;

validate the location from features of the additional signal subsequent to removing the at least a portion of the user information;

detect an event from the features of the normalized signal version of the emergency call signal based on the validated location;

associate the validated location with an obtained event truthfulness probability for the event; and

send the event to a Public Safety Answering Point (PSAP).

12. The system of claim 11, further comprising instructions configured to:

determine a severity based on characteristics of the normalized signal version of the emergency call signal and the additional normalized signal; and

associate the severity with the event.

13. The system of claim 11, wherein instructions configured to access an additional normalized signal comprises instructions configured to access the additional normalized signal that includes one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI).

14. The system of claim 11, wherein instructions configured to remove at least a portion of the user information from the additional normalized signal comprise instructions configured to remove one or more of:

confidential information, patient information, personally identifiable information (PII), personal health information (PHI), sensitive personal information (SPI), or Payment Card Industry information (PCI) from the additional normalized signal.

15. The system of claim 11, further comprising instructions configured to listen for additional normalized signals in geo cells within the specified distance of the location prior to accessing the one or more additional normalized signals.

16. The system of claim 11, wherein instructions configured to derive the probability that the emergency call signal originated from the location comprise instructions configured to derive the location from features of an audio overlay indicating a location of the emergency call signal.

17. The system of claim 11, wherein instructions configured to send the event to the PSAP comprise instructions configured to send the event to the PSAP prior to a carrier network sending phase II data to the PSAP.
