Abstract

For determining user risk using multiple data types, an apparatus is disclosed. A system, method, and program product also perform the functions of the apparatus. The apparatus for determining user risk using multiple data types includes a processor and a memory. The memory stores code executable by the processor. The processor receives first data about a user and determines a first probability of the user being at risk using the first data. In response to the first probability exceeding a first threshold, the processor receives second data, the second data being a different type of data than the first data. The processor also determines a second probability of the user being in danger using the second data. In response to the second probability exceeding a second threshold, the processor initiates an alarm.

First claim

What is claimed is:

1 . An apparatus comprising:
a processor; a memory that stores code executable by the processor to: receive first data about a user; determine a first probability of the user being at risk using the first data, the first data comprising at least one of: movement data and biometric data; activate one or more additional sensors in response to the first probability of the user being at risk exceeding a first threshold; gather second data about the user from a second set of sensors, the second set comprising the activated one or more additional sensors, the second data being a different type of data than the first data, wherein gathering the second data is triggered by the first probability of the user being at risk exceeding a first threshold; determine a second probability of the user being at risk using at least the second data; and initiate an alarm in response to the second probability of the user being at risk exceeding a second threshold.

2 . The apparatus of claim 1 , wherein the processor further stores the second data to a remote storage device in response to the second probability of the user being at risk exceeding the second threshold.

3 . The apparatus of claim 1 , wherein the processor further identifies a location of the user in response to the first probability exceeding a first threshold, wherein determining the second probability comprises increasing the second probability of the user being in danger in response to the user being located in a higher risk geographic area.

4 . The apparatus of claim 1 , wherein receiving the first data comprises receiving movement data of the user and wherein determining a first probability of the user being at risk using the first data comprises calculating a degree to which a pattern of movement indicated by the movement data differs from a baseline pattern.

5 . The apparatus of claim 1 , wherein receiving the first data comprises receiving biometric data of the user and wherein determining a first probability of the user being at risk using the first data comprises calculating whether the biometric data indicates a state of user stress.

6 . The apparatus of claim 1 , wherein receiving the second data comprises capturing audio data, and wherein determining the second probability of the user being in danger comprises analyzing the audio data to determine whether the user speaks a predetermined phrase.

7 . The apparatus of claim 1 , wherein receiving the second data comprises capturing image data, and wherein determining the second probability of the user being in danger comprises analyzing the image data for one or more of: an indication of a conflict, an indication of an injury, and an indication of damage.

8 . The apparatus of claim 1 , wherein initiating the alarm comprises contacting one of: a predetermined contact and a predetermined device.

9 . A method comprising:
receiving, by use of a processor, first data about a user; determining a first probability of the user being at risk using the first data, the first data comprising at least one of: movement data and biometric data; activating one or more sensors in response to the first probability exceeding a first threshold; collecting second data about the user using the activated one or more sensors, the second data being a different type of data than the first data; determining a second probability of the user being in danger based on at least the second data; and initiating an alarm based on the second probability exceeding a second threshold.

10 . The method of claim 9 , further comprising storing the second data to a remote storage device in response to the second probability exceeding the second threshold.

11 . The method of claim 9 , further comprising identifying a location of the user in response to the first probability exceeding a first threshold, wherein determining the second probability comprises increasing the second probability of the user being in danger in response to the user being located in a higher risk geographic area.

12 . The method of claim 9 , wherein receiving the first data comprises receiving movement data of the user and wherein determining the first probability of the user being at risk using the first data comprises calculating a degree to which a pattern of movement indicated by the movement data differs from a baseline pattern.

13 . The method of claim 12 , wherein receiving the first data further comprises receiving biometric data of the user and wherein determining the first probability of the user being at risk using the first data comprises calculating whether the biometric data indicates a state of user stress.

14 . The method of claim 9 , wherein receiving the second data comprises capturing audio data, and wherein determining the second probability of the user being in danger comprises analyzing the audio data to determine whether the user speaks a predetermined phrase.

15 . The method of claim 14 , wherein receiving the second data further comprises capturing image data, and wherein determining the second probability of the user being in danger further comprises analyzing the audio data and the image data for one or more of: an indication of a conflict, an indication of an injury, and an indication of damage.

16 . The method of claim 9 , wherein initiating the alarm comprises contacting one of: a predetermined contact and a predetermined device.

17 . The method of claim 16 , wherein initiating the alarm further comprises transmitting one or more of the second data and user location data to the predetermined contact or predetermined device.

18 . A program product comprising a computer readable storage medium that stores code executable by a processor, the executable code comprising code to:
receive first data about a user, the first data comprising data collected by a first set of data sources; determine a first probability of the user being at risk using the first data; activate one or more sensors from a second set of data sources in response to the first probability of the user being at risk exceeding a first threshold; receive second data about the user from the activated one or more sensors, the second data being a different type of data than the first data; determine a second probability of the user being at risk using the second data; and initiate an alarm in response to the second probability of the user being at risk exceeding a second threshold.

19 . The program product of claim 18 ,
wherein receiving the first data comprises receiving one or more of: movement data of the user and biometric data of the user; and wherein receiving the second data comprises receiving one or more of: video data, audio data, and location data.

20 . The program product of claim 18 , wherein initiating the alarm comprises sending the second data to one of: a predetermined contact and a predetermined device.
