基于区块链的反诈骗系统框架设计与分析

Design and Analysis of Anti-Fraud System Framework Based on Blockchain

摘要: 预防电信诈骗是当下社会比较火热的一个话题。基于区块链的防诈骗(Anti-Fraud)系统能够弥补传统反诈骗系统的不足，比如证难取、损难止以及不信任等。区块链作为颠覆性的新一代信息技术，因其具有去中心、去信任、防篡改以及历史数据可追溯等特点，对预防电信诈骗起到很好的辅助作用。本文通过分析分布式数据库、共识机制、密码学、激励机制以及智能合约等区块链的核心技术，进而设计了基于区块链的反诈骗系统框架，并从数据上链、身份认证以及合约控制等三个方面出发逐一对该系统功能进行介绍，以期未来能够实现该系统，从而保障用户的财产安全，同时为相关部门提供借鉴。

Abstract: Telecom fraud prevention is a hot topic in today’s society. The anti-fraud system based on block-chain can make up for the shortcomings of traditional anti-fraud systems, such as difficult to obtain evidence, difficult to prevent damage and distrust. As a disruptive new generation of information technology, blockchain has the characteristics of decentralization, trustlessness, anti-tampering and traceability of historical data, which plays a good auxiliary role in preventing telecommunication fraud. By analyzing the core technologies of blockchain such as distributed database, consensus mechanism, cryptography, incentive mechanism and smart contract, this paper designs an anti-fraud system framework based on blockchain, and analyzes data on the chain, identity authenti-cation and contract control. Starting from three aspects, this paper will introduce the functions of the system one by one, in order to realize the system in the future, so as to ensure the safety of users’ property and provide reference for relevant departments.
