However, the state of the art concepts are not applicable due to several limitations. One limitation is the scalability of blockchains with regard to the number of transactions that can be processed by the network. The well-established technology in tracking products is based on RFID chips that can be cloned. This paper provides insights into how objects can be protected and monitored by a varnish with a unique crack pattern, as an example of a Physical Unclonable Function. The perceptual hash of the unique pattern is used to encrypt the associated data to ensure privacy. Instead of logging each event on the blockchain individually, which is not possible due to the limited transaction throughput, OriginStamp is used to preserve data integrity on the blockchain. OriginStamp aggregates events, combines them through hashing and embeds this hash into a Bitcoin transaction. Once the Bitcoin network mines the transaction into a block and confirms it, the timestamp is considered as immutable proof of existence. With this approach, the integrity of tracking data cannot be contested. In the future, the craquelure-based tracking approach could be extended to supply chain integration to secure the origin of products, including prevention of counterfeiting, securing the place of manufacture for trademark law or state surveillance of the agricultural economy.</dcterms:abstract> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2018-08-07T11:51:39Z</dcterms:available> <dc:contributor>Wortner, Patrick</dc:contributor> <dc:creator>Hepp, Thomas</dc:creator> <dc:creator>Wortner, Patrick</dc:creator> <dc:contributor>Schönhals, Alexander</dc:contributor> <dcterms:title>Securing Physical Assets on the Blockchain : Linking a novel Object Identification Concept with Distributed Ledgers</dcterms:title> <dcterms:issued>2018</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2018-08-07T11:51:39Z</dc:date> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/36"/> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/42993/1/Hepp_2-oj8la18i8tqw0.pdf"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/36"/> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/42993/1/Hepp_2-oj8la18i8tqw0.pdf"/> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/42993"/> <dc:contributor>Hepp, Thomas</dc:contributor> <dc:rights>terms-of-use</dc:rights> <dc:contributor>Gipp, Bela</dc:contributor> </rdf:Description> </rdf:RDF>
