About this Event

Speaker biography

Michael Kozicki joined Arizona State University in 1985 from the semiconductor industry and is currently a Professor in the School of Electrical, Computer and Energy Engineering and Senior Global Futures Scientist. His research focuses on the development of novel materials, processes, and devices in applications ranging from information storage to digital identity. He has almost 70 US patents granted and several commercialized products, achievements which led to his election as a Fellow of the National Academy of Inventors in 2015. Michael is a founder of several start-up companies, including Densec ID.

Seminar Details

The complex nature of the agri-food enterprise has created an environment in which the extent and consequences of contamination, waste, and food fraud are expanding due to inadequate information. The USDA and FDA are mindful these issues, and both stress the role of advanced data sciences in their mitigation. The security and efficiency of Distributed Ledger Technologies such as blockchain make them highly attractive for handling data in modern supply chains, which is why the world’s largest information technology companies have embraced these and are currently offering products to allow the digitization of transactions in the agri-food ecosystem (e.g., IBM Food Trust). The problem with this approach is that the information held is only as good as the information entered, and the weakest link is most often the physical element that connects items in the real world to their digital identity in the Cloud. In current implementations, this “digital trigger” can be as simple and cheap as a printed code, or it may take the form of the more sophisticated but more expensive RFID tag. Unfortunately, none of these tend to get used at the level of individual items or small batches due to the costs associated with “uniquification” or the price of the triggers themselves, and this lack of granularity creates knowledge gaps which exacerbate waste issues, especially in the wake of a recall. Ease of replication is another weakness of printed triggers, and this has allowed corruption to flourish due to counterfeiting and deliberate mislabelling.

 

This talk examines the issues surrounding digital identity in agri-food supply chains and presents a novel approach to digital triggers developed via USDA support. These physical identifiers are unusual as they are based on naturally formed patterns with a dendritic topology. Dendrites are branching structures that possess a singular set of features for every instance of pattern formation, providing an individual geometric shape that leads to a unique digital ID for every item to which the identifier is attached. These can be formed on labels or directly on the items themselves with minimal cost and may be read using a cell phone, bringing item-level identification and authentication into the hands of the consumer. The materials, processes, and systems involved in their formation and reading will be described, and the results of pilot applications within and beyond agriculture will be presented.
