CONFIRMING DELIVERY LOCATION USING RADIO FINGERPRINTING
First Claim
1. A method for confirming a desired delivery location of an item, comprising:
- collecting, at a first time, first information about one or more wireless signals detected at a first location, the first information including one or more of a signal identifier, a signal strength, or a signal frequency of the one or more wireless signals;
identifying second information about one or more wireless signals detected at a second time at a desired delivery location, wherein the second time is previous to the first time;
determining a number of overlapping wireless signals, wherein an overlapping wireless signal is a wireless signal that is included in both the first information and second information;
determining a detected signal strength in the first information and second information for each overlapping wireless signal;
determining a score representing a probability that the first location is the same as the desired delivery location, wherein the score is determined using the number of overlapping wireless signals and the corresponding determined signal strengths in the first information and second information; and
confirming that the first location is the same as the desired delivery location in response to the score being above a threshold.

Abstract
A system and method for confirming a delivery location. A delivery agent equipped with a device, for example, a mobile device, delivers a package to a location. When the package is delivered, the delivery agent triggers a delivery-event on the device, and in response to the delivery-event the device determines an RF fingerprint at the location. The RF fingerprint is stored, and a comparison of the RF fingerprint to previously stored RF fingerprints correlated to particular locations is performed. If the RF fingerprint determined by the first device corresponds to a previously stored RF fingerprint at the correct delivery location, the current delivery location is confirmed as correct.
