摘要:

区块链账本数据是公开透明的。一些攻击者可以通过分析账本数据来获取敏感信息,这对用户的交易隐私造成威胁。鉴于区块链交易隐私保护的重要性,首先分析产生交易隐私泄露的原因,并将交易隐私分为交易者身份隐私和交易数据隐私两类;其次,从这两种不同类型的隐私角度,阐述现有的面向区块链交易的隐私保护技术;接着,鉴于隐私保护和监管之间的矛盾性,介绍兼具监管的交易身份隐私保护方案;最后,总结和展望了区块链交易隐私保护技术未来的研究方向。

关键词: 区块链, 交易隐私保护, 身份隐私, 交易数据隐私, 交易监管

Abstract:

Blockchain ledger is open and transparent. Some attackers can obtain sensitive information through analyzing the ledger data. It causes a great threat to users’ privacy preservation of transaction. In view of the importance of blockchain transaction privacy preservation, the causes of the transaction privacy leakage were analyzed at first, and the transaction privacy was divided into two types: the transaction participator’s identity privacy and transaction data privacy. Then, in the perspectives of these two types of transaction privacy, the existing privacy-preserving technologies for blockchain transaction were presented. Next, in view of the contradiction between the transaction identity privacy preservation and supervision, transaction identity privacy preservation schemes considering supervision were introduced. Finally, the future research directions of the privacy-preserving technologies for blockchain transaction were summarized and prospected.

Key words: blockchain, transaction privacy preservation, identity privacy, transaction data privacy, transaction supervision
