Abstract
This paper proposes an address authentication method based on a user’s location history. Address authentication refers to actual residence verification, which can be used in various fields such as personnel qualification, online identification, and public inquiry. In other words, accurate address authentication methods can reduce social cost for actual residence verification. For address authentication, existing studies discover the user’s regular locations, called location of interest (LOI), from the location history by using clustering algorithms. They authenticate an address if the address is contained in one of the LOIs. However, unnecessary LOIs, which are unrelated to the address may lead to false authentications of illegitimate addresses, that is, other users’ addresses or feigned addresses. The proposed method tries to reduce the authentication error rate by eliminating unnecessary LOIs with the distinguishing properties of the addresses. In other words, only few LOIs that satisfy the properties (long duration, high density, and consistency) are kept and utilized for address authentication. Experimental results show that the proposed method decreases the authentication error rate compared with previous approaches using time-based clustering and density-based clustering.
Highlights
With the rapid growth of smart devices, such as smartphones, wearable devices, and Internet of Things devices, numerous location-based services have been developed
The performances are described in terms of three error factors: false positive rate (FPR), false negative rate (FNR), and average error rate (AER)
FPR means the rate of falsely accepting illegitimate addresses and FNR means the rate of falsely rejecting legitimate addresses
Summary
With the rapid growth of smart devices, such as smartphones, wearable devices, and Internet of Things devices, numerous location-based services have been developed. This paper focuses on address authentication based on a user’s location history. Address authentication refers to the process of verifying that the user resides at the recorded home address or works at the recorded workplace address. Qualifications and benefits with regard to the address usually depend on the pre-registered address by the government. The registered address must be consistent with the actual residence. There are many cases of inconsistencies and even unknown residences because the registered address is set by the individual moving-in report. False and omitted reports lead to the inconsistencies and there is no suitable way of discovering them. An address authentication method only in case of need can be one of the solutions avoiding this waste of social cost and verifying qualification sustainably
