十多年来，射频识别（RFID）技术在供应链中提供防伪措施方面非常有效。然而，在后供应链中，RFID标签的真实性无法得到保证，因为这些标签在公共空间中很容易被克隆。在本文中，我们提出了一种新的rfid产品所有权管理系统（POMS），可用于后供应链的防伪产品。为此，我们利用比特币区块链的理念，任何人都可以检查拥有余额的证明。使用拟议的POMS，如果卖家不拥有假货的所有权，即使有真正的RFID标签信息，顾客也可以拒绝购买假货。我们采用基于区块链的去中心化应用平台以太坊实现了概念验证实验系统，并评估了其性价比。结果表明，通常情况下，管理一个产品多达六次转移的所有权的成本不到1美元。
For more than a decade now, radio frequency identification (RFID) technology has been quite effective in providing anti-counterfeits measures in the supply chain. However, the genuineness of RFID tags cannot be guaranteed in the post supply chain, since these tags can be rather easily cloned in the public space. In this paper, we propose a novel product ownership management system (POMS) of RFID-attached products for anti-counterfeits that can be used in the post supply chain. For this purpose, we leverage the idea of Bitcoin's blockchain that anyone can check the proof of possession of balance. With the proposed POMS, a customer can reject the purchase of counterfeits even with genuine RFID tag information, if the seller does not possess their ownership. We have implemented a proof-of-concept experimental system employing a blockchain-based decentralized application platform, Ethereum, and evaluated its cost performance. Results have shown that, typically, the cost of managing the ownership of a product with up to six transfers is less than U.S. $1.
