Biometric Blockchain: A Better Solution for the Security and Trust of Food Logistics
This addresses security and trust issues in food logistics, particularly for preventing incidents like mislabeled foods causing harm, though it is an incremental improvement by adding biometrics to existing blockchain technology.
The paper tackles the problem of authenticating data creators and users in blockchain systems for food logistics by proposing a Biometric Blockchain (BBC) protocol that incorporates biometric cues, resulting in improved identification of responsible parties and reduced risks like fake foods or mislabeled products.
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.
