Claim:
1. A method, comprising: receiving, by a server and from a mobile device, a plurality of accelerometer values generated by the mobile device; determining, by the server and based on the plurality of accelerometer values, a plurality of acceleration magnitude values; determining, by the server, that at least one of the plurality of acceleration magnitude values satisfies an acceleration magnitude threshold; identifying, by the server, a potential fall event at a time period based on the at least one of the plurality of acceleration magnitude values satisfying the acceleration magnitude threshold, determining, by the server and based on identifying the potential fall event, a quantity of the set of acceleration magnitude values that are below a free fall magnitude threshold; determining, by the server, a total free fall interval based on the quantity of the set of acceleration magnitude values that are below the free fall magnitude threshold; determining, by the server, that the total free fall interval satisfies a free fall interval threshold; determining, by the server and based on the total free fall interval satisfying the free fall interval threshold, that a non-fall event occurred; and transmitting, by the server and to a service provider device, an indication that the non-fall event occurred to indicate that the potential fall event is a false positive.
