A Traceable and Verifiable Tobacco Products Logistics System with GPS and RFID Technologies

Abstract

Tobacco products are an addictive commodity. According to the World Health Organization’s (WHO) latest statistics data, tobacco kills more than eight million people each year. In 2003, the WHO proposed the Framework Convention on Tobacco Control (FCTC) to provide an effective framework for the control of tobacco products to governments around the world. In the field of tobacco products, the hardest problem is how to prevent counterfeit tobacco products and smuggling. To solve the problems, we proposed a blockchain-based traceable and verifiable logistics system for tobacco products with global positioning system (GPS) and radio-frequency identification (RFID) Technologies. In this research, we provide an overview of system architecture, and also define the protocol and the smart contract in every phase that stores data into the blockchain center. We realized a decentralized database and authentication system that uses blockchain and smart contract technology; every protocol in every phase was designed to achieve the integrity of data and non-repudiation of message. Every tobacco product’s shipping record will be completed by scanning the RFID tag and retrieving the GPS with a mobile reader, where the record will be updated and validated in the blockchain center. In the end, the security and costs of the system were analyzed, and a comparison was made with the EU’s (European Commission) method. Our system is more flexible for transportation, more secure in the communication protocol, and more difficult to tamper and forge data. In general, the proposed scheme solved the problem of tobacco products counterfeiting and tracking issues.

Food Traceability in Agriculture Value Chain: Evidence from Pakistani Mango Growers

“…This also confirms our hypothesis that the growers' attitude positively influences their intention toward a traceable mango value chain. These findings are consistent with the findings of [25]. Similarly, [26] indicated that attitude is fundamental in influencing intentions to perform different safe food-handling behaviors.…”

Blockchain-Based Community Safety Security System with IoT Secure Devices

“…It adopts a modular universal framework, unique identity management, access control functions, and channels to transfer data. Those features are suitable for various industrial applications, such as supply chain tracking [58,59], financial management [60], insurance financial [61], healthcare records [62,63], etc. The advantages of the blockchain's characteristics are listed as follows:…”

The second near-infrared fluorescence concealed imaging for identifying smuggled baggage

“…If the suspect finds abnormal marks on the appearance of the luggage when picking up the luggage, the suspects will give up the luggage in order to escape the guilt, and the customs staff will not be able to catch the suspect in time. Although the contraband can be detected, catch the suspect will be not in time [ [12] , [13] , [14] ]. For RFID tracking system, luggage tags contain sensitive information such as the passenger's name and destination, which could be stolen.…”
