Double-Edged Sword: Incentivized Verifiable Product Path Query fo...

Querying the path information of individual products in a supply chain is key to many applications. RFID (Radio-Frequency IDentification) is a main technology to enable product path information query today. With RFID technology, supply chain participants can efficiently track products in transit and record their production information in databases. In this paper, we investigate the following question: how can we conduct privacy-preserving product path information query with verifiability on an R
