Abstract
In one embodiment, a method includes accessing magnetic data from a magnetic-measurement device. The magnetic data corresponds to one or more locations of the magnetic-measurement device. The method includes accessing geofencing data corresponding to an area; comparing the magnetic data with the geofencing data; based on the comparison, determining that the locations correspond to the area; and, based on the determination, authenticating the magnetic-measurement device for access to one or more resources.
Claims25
A method comprising:
- by an electronic device, accessing magnetic data from a magnetic-measurement device, wherein:
- the magnetic data comprises one or more candidate magnetic recordings corresponding to one or more locations of the magnetic-measurement device;
- and
- one or more of the candidate magnetic recordings comprise a first series of first magnetic-field values that represents a first magnetic recording that comprises a first set of first magnetic-field measurements that are each represented by one of the first magnetic-field values;
- by the electronic device, accessing geofencing data corresponding to an area, wherein:
- the geofencing data comprises one or more reference magnetic recordings corresponding to the area;
- and
- one or more of the reference magnetic recordings comprise a second series of second magnetic-field values that represents a second magnetic recording that comprises a second set of second magnetic-field measurements that are each represented by one of the second magnetic-field values;
- by the electronic device, comparing the magnetic data with the geofencing data, wherein the comparison comprises:
- approximately aligning the first and second series with each other;
- calculating a difference between the first and second series as aligned with each other;
- and
- determining a similarity between the first and second series based on the difference;
- by the electronic device, based on the comparison, determining that the locations correspond to the area;
- and
- by the electronic device, based on the determination, authenticating the magnetic-measurement device for access to one or more resources.
