Locker-Scale Positioning and Dynamic Access Key Management for IoT-based Smart Delivery Services

The delivery service has become an essential service for daily use. Customers can purchase items easily and conveniently through the delivery service. The advantage of the delivery service is that the item someone purchases is delivered to the recipient’s house. So, the recipient doesn‘t have responsibility for going to a market to buy something. Additionally, even if the recipient does not stay house, he/she can receive the parcel by using an Unmanned Delivery Locker (UDL). Almost UDL is used as an access key, such as a password, QR code, etc., to open the locker. The access key is used to prevent non-designated persons from opening locker doors. However, if the access key is leaked, the security of the parcel is at risk. To address this issue, this paper comes up with a novel delivery system using a dynamic access key management scheme based on locker-scale positioning. The system does not provide an access key to the recipient when the parcel is stored. Instead, the access key is provided to the recipient at a time when he/she arrives at the UDL. To identify that the recipient has arrived at UDL, the positioning with Bluetooth Low Energy (BLE) is used and experimented with. The results of an experiment show that the accuracies are achieved 86.67% with 4 lockers, 89.61% with 6 lockers.
