Abstract

Systems and methods for source verification are disclosed. A method includes: receiving, by a computing device, a report from a first source; determining, by the computing device, the first source is listed in a source repository based on receiving the report; selecting, by the computing device, a second source at a location remote from the first source based on the source being listed in the source repository; confirming, by the computing device, the report from the first source based on information received from the second source; repeating, by the computing device, the selecting and the confirming until a value of information in the report from the second source exceeds an information trust level value for the report.

First claim

What is claimed is:

1 . A computer-implemented method, comprising:
receiving, by a computing device, a report from a first source; determining, by the computing device, the first source is listed in a source repository based on receiving the report; selecting, by the computing device, a second source at a location remote from the first source based on the source being listed in the source repository; confirming, by the computing device, the report from the first source based on information received from the second source; repeating, by the computing device, the selecting and the confirming until a value of information in the report from the second source exceeds an information trust level value for the report.

2 . The method of claim 1 , wherein the first source is an unknown source.

3 . The method of claim 1 , wherein the source repository is an untrusted source repository.

4 . The method of claim 3 , further comprising determining the location of the first source based on the first source being listed in the untrusted source repository.

5 . The method of claim 4 , wherein the information trust level value for the report is based on a type of report and profile information for the type of report.

6 . The method of claim 5 , wherein the selecting the second source is based on proximity of the second source to the first source.

7 . The method of claim 6 , further comprising selecting an area around the first source and selecting the second source from a plurality of second sources within the area around the first source, the selected second source being one of the plurality of second sources that is farthest away from the first source.

8 . The method of claim 7 , wherein the confirming the report is based on automatic verification.

9 . The method of claim 8 , wherein the confirming the report is based on formal verification.

10 . The method of claim 9 , wherein the value of information in the report from the second source is based on the type of report, a location of the report, profile information for the type of report, size of an emergency in the report, and number of people affected by the emergency in the report.

11 . The method of claim 10 , further comprising dispatching emergency in response to the value to information in the report from the second source exceeding the information trust level value.

12 . A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer device to cause the computer device to:
receive a report from a first user device of a first source; assign an information trust level value to the report from the first source based on receiving the report; select a second user device of a second source at a location remote from the user device of the first source based on assigning the information trust level value to the report from the first source; assign an information value to information from the second source based on receiving information from the second source; confirm the report with the second user device of the second source based on determining the information value exceeds the information trust level value.

13 . The computer program product of claim 12 , wherein the information trust level value for the report is based on a type of report and profile information for the type of report.

14 . The computer program product of claim 12 , wherein the information value is based on the type of report, a location of the report, profile information for the type of report, size of an emergency in the report, and number of people affected by the emergency in the report.

15 . The computer program product of claim 12 , further comprising:
selecting a third source based on determining the information value does not exceed the information trust level value; assigning a second information value to information from the third source based on receiving information from the third source; confirming the report with the third source based on an aggregate value of the information value and the second information value exceeds the information trust level value.

16 . The computer program product of claim 15 , wherein the second information value is based on the type of report, a location of the report, profile information for the type of report, size of an emergency in the report, and number of people affected by the emergency in the report.

17 . A system comprising:
a CPU, a computer readable memory and a computer readable storage medium associated with a computing device;
program instructions to receive a report from an unknown source at a location;
program instructions to determine other unknown sources near the location;
program instructions to select a second unknown source from the other unknown sources;
program instructions to determine whether information from the second unknown source exceeds an information trust level value; and
program instructions to repeat the selecting until information from a number of unknown sources exceeds the information trust level value;
wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.

18 . The system of claim 17 , wherein the information value is based on the type of report, a location of the report, profile information for the type of report, size of an emergency in the report, and number of people affected by the emergency in the report.

19 . The system of claim 17 , further comprising checking a social connection of the unknown source and the second unknown source.

20 . The system of claim 19 , further comprising selecting a third unknown source based on the social connection of the unknown source and the second unknown source.
