Biometric Blockchain: A Better Solution for the Security and Trust of Food Logistics

TL;DR

This paper introduces Biometric Blockchain (BBC), a novel protocol that uses biometric cues to enhance security and accountability in food logistics, addressing issues like fake foods and mislabeling.

Contribution

The paper proposes a biometric-based blockchain protocol that explicitly identifies data creators and users, improving security and traceability in food logistics systems.

Findings

BBC can verify data authenticity in food logistics

It clearly records responsible parties for data and labels

Enhances security against food fraud and mislabeling

Abstract

Blockchain has been emerging as a promising technology that could totally change the landscape of data security in the coming years, particularly for data access over Internet-of-Things and cloud servers. However, blockchain itself, though secured by its protocol, does not identify who owns the data and who uses the data. Other than simply encrypting data into keys, in this paper, we proposed a protocol called Biometric Blockchain (BBC) that explicitly incorporate the biometric cues of individuals to unambiguously identify the creators and users in a blockchain-based system, particularly to address the increasing needs to secure the food logistics, following the recently widely reported incident on wrongly labelled foods that caused the death of a customer on a flight. The advantage of using BBC in the food logistics is clear: it can not only identify if the data or labels are authentic, but also clearly record who is responsible for the secured data or labels. As a result, such a BBC-based solution can great ease the difficulty to control the risks accompanying the food logistics, such as faked foods or wrong gradient labels.
