Abstract

Procuratorates, as the prosecutor in public interest litigation (PIL), need to obtain evidence from other PIL stakeholders including citizens, companies, governmental agencies, IoT monitoring devices and so on. However, the evidence sharing is not smooth due to the lack of secure data sharing and privacy protection during case investigation and evidence collection. Therefore, the authors propose a consortium blockchain-based secure data sharing and privacy protection scheme named PILChain. The involved organizations are connected as peers in PILChain. The safety of uploaded evidence and user privacy can be guaranteed with a fine-grained access control and zero-knowledge identity proof. InterPlanetary File System is introduced to store large evidence files off-chain, further enhancing the data security and system scalability. The security of PILChain is analyzed in terms of access control, evidence confidentiality, evidence integrity, traceability, privacy, and scalability. Last, the authors evaluate the performance of the developed prototype system by implementing PILChain on Hyperledger Fabric.
基于区块链的公益诉讼证据共享系统
检察院作为公益诉讼的检察官,需要从公益诉讼的其他利益相关者那里获取证据,包括公民、公司、政府机构、物联网监控设备等。然而,在案件调查取证过程中,由于缺乏安全的数据共享和隐私保护,证据共享并不顺利。因此,作者提出了一种基于区块链的联盟安全数据共享和隐私保护方案,命名为PILChain。所涉及的组织在PILChain中作为对等体连接。通过细粒度的访问控制和零知识身份证明,可以保证上传证据的安全性和用户隐私。引入星际文件系统,实现大型证据文件的链下存储,进一步提高了数据的安全性和系统的可扩展性。从访问控制、证据保密性、证据完整性、可追溯性、隐私性和可扩展性等方面分析了PILChain的安全性。最后,通过在Hyperledger Fabric上实现PILChain,对所开发的原型系统的性能进行了评估。

期刊介绍: Authors are encouraged to submit manuscripts that are consistent to the following submission themes: (a) Cross-National Studies. These need not be cross-culture per se. These studies lead to understanding of IT as it leaves one nation and is built/bought/used in another. Generally, these studies bring to light transferability issues and they challenge if practices in one nation transfer. (b) Cross-Cultural Studies. These need not be cross-nation. Cultures could be across regions that share a similar culture. They can also be within nations. These studies lead to understanding of IT as it leaves one culture and is built/bought/used in another. Generally, these studies bring to light transferability issues and they challenge if practices in one culture transfer.
