Abstract
A computer-implemented information verification method, system, and non-transitory computer readable medium, include measuring a first signal strength from a user device to a second device, where the first signal strength is measured from the perspective of the user device, measuring a second signal strength from the second device to the user device, where the second signal strength is measured from the perspective of the second device, comparing the first signal strength with the second signal strength, and verifying the information, based on a result of said comparing.
Claims20
A computer-implemented information verification method, the method comprising:
- measuring a first signal strength from a user device to a second device, where the first signal strength is measured from the perspective of the user device;
- measuring a second signal strength from the second device to the user device, where the second signal strength is measured from the perspective of the second device;
- measuring a third signal strength between a third device and the user device, where the third signal strength is measured from the perspective of the third device;
- comparing the first signal strength with the second signal strength and the first signal strength with the third signal strength;
- and
- verifying the information, based on a result of said comparing.
A computer program product for verifying information, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, readable/executable by a computer, to cause the computer to perform a method comprising:
- measuring a first signal strength from a user device to a second device, from the perspective of the user device;
- measuring a second signal strength from the second device to the user device, from the perspective of the second device;
- measuring a third signal strength between a third device and the user device, where the third signal strength is measured from the perspective of the third device;
- comparing the first signal strength with the second signal strength and the first signal strength with the third signal strength;
- and
- verifying the information based on a result of the comparing.
A location verification system, said system comprising:
- a processor;
- and
- a memory, the memory storing instructions to cause the processor to:
- measure a first signal strength from a user device to a second device, where the first signal strength is measured from the perspective of the user device;
- measure a second signal strength from the second device to the user device, where the second signal strength is measured from the perspective of the second device;
- measuring a third signal strength between a third device and the user device, where the third signal strength is measured from the perspective of the third device;
- comparing the first signal strength with the second signal strength and the first signal strength with the third signal strength;
- and
- verifying the information, based on a result of said comparing.
