Industrial Internet of Things (IIoT) is revolutionizing the retail industry for manufacturers, suppliers, and retailers to improve operational efficiency and consumer experience. In IIoT-enabled retail marketing, reputation systems play a critical role to boost mutual trust among industrial entities and build consumer confidence. In this paper, we focus on reputation management in the consumer-retailer channel, where retailers can accumulate reputations from consumer feedbacks. To encourage consumers to post feedbacks without worrying about being tracked or retaliated, we propose an anonymous reputation system that preserves consumer identities and individual review confidentialities. To increase system transparency and reliability, we further exploit the tamper-proof nature and the distributed consensus mechanism of the blockchain technology. With system designs based on various cryptographic primitives and a Proof-of-Stake consensus protocol, our blockchain-based reputation system is more efficient to offer high levels of privacy guarantees compared with existing ones. Finally, we explore the implementation challenges of the blockchain-based architecture and present a proof-of-concept prototype system by Parity Ethereum. We measure the on/off-chain performance with the scalability discussion to demonstrate the feasibility of the proposed system.

PoS 区块链上支持 IIoT 的零售营销的匿名声誉系统


工业物联网 (IIoT) 正在为制造商、供应商和零售商彻底改变零售业，以提高运营效率和消费者体验。在工业物联网支持的零售营销中，声誉系统在增强工业实体之间的相互信任和建立消费者信心方面发挥着关键作用。在本文中，我们重点关注消费者零售商渠道中的声誉管理，零售商可以从消费者反馈中积累声誉。为了鼓励消费者发布反馈而不必担心被跟踪或报复，我们提出了一个匿名声誉系统，以保护消费者身份和个人评论的机密性。为了提高系统的透明度和可靠性，我们进一步利用区块链技术的防篡改特性和分布式共识机制。通过基于各种加密原语和权益证明共识协议的系统设计，与现有系统相比，我们基于区块链的信誉系统能够更有效地提供高水平的隐私保证。最后，我们探讨了基于区块链的架构的实施挑战，并提出了 Parity Ethereum 的概念验证原型系统。我们通过可扩展性讨论来衡量链上/链下性能，以证明所提出系统的可行性。
