公检法基于区块链和大数据共建证据链

电子设备跟人们的生活密切相关,电子数据已经被列为八大证据之一.电子数据通常采用集中存储的方式,容易被篡改和破坏,难于保证数据的真实性.而且公安局、检察院和法院对于电子证据走线下投递的模式,工作效率低且过程中存在不安全的因素.为此,基于区块链技术和边缘存储技术,在公安局、检察院、法院之间打造一个联盟链,利用区块链的多方存...

An Evidence Chain System based on Blockchain and Big Data Technology

Electronic equipment is closely related to people's life,and electronic data is defined as one of the eight evidences.Electronic data is usually stored in a centralized store,which is easy to be tampered with and destroyed,and it is difficult to ensure the authenticity of the data.Moreover,the public security bureau,the procuratorate,and the courts have low efficiency and unsafe factors in the delivery electronic evidence.Therefore,based on the blockchain technology and edge storage technology,this paper builds an evidence chain system among the public security bureau,procuratorate and courts,and uses the blockchain's multi-party storage,tamper proof,traceable,CA authentication,digital signature features and the edge storage's decentralized distributed storage,nearby access,elastic expansion features,so as to realize the on-chain and storage of electronic evidence,improve work efficiency and guarantee data security.
