Extended Abstract
Product counterfeiting and fraud are costly for the industry and potentially dan-
gerous for customers, especially if medicine and food products are affected. These
problems are wide-spread across many industries and supply chain processes. To
address these challenges, Laava provides a novel type of tags for individual item
tracking with unique features. The tags are designed in a way that makes coun-
terfeiting harder, and has numerous advantages over barcodes and QR codes.
    In this talk, Laava will outline the basic functionality of its solution and
describe the blockchain-based components in some detail. This includes the fol-
lowing aspects. Laava registers new tags on creation in a specific smart contract
on the Ethereum blockchain, and scans of the tags along the supply chain are
registered as well. Events include updates to the tag status, e.g., created, in use,
or invalid.
    To detect fraudulent activities, Laava uses two complementary methods:
 – Conformance checking, which compares the observed events against the nor-
   mative model of the supply chain process for the item in question.
 – A business rule engine, that checks if item-specific conditions have been
   violated.
If either method detects abnormal event sequences, it raises an alert. Depending
on the configuration, the alert is either screened by a human expert for evalua-
tion or automatically marks the tag as invalid. If a supply chain participant or
customer scans the tag, they see the status.
    This work is done in a project between Laava and Data61, CSIRO, using
tools from Data61: CCaaS[1] for online conformance checking and Regerator[2]
for generating the smart contract code.
