基于区块链技术的广播电视数据采集系统研究

Research on Radio and TV Data Acquisition System Based on Blockchain Technology

随着媒体融合、数字化和网络化的快速发展,广播电视行业在内容流量产出、数据传输及用户数据规模等方面迅速增长,导致数据压力逐年增大。可见,采用先进的数据采集处理技术对提高广播电视监测效率及数据分流具有重要作用。基于区块链技术的去中心化特性,将省中心化的监测中心改造成分布式监测网络。将监测数据保存在各地数据库中,利用时间戳、分布式共识及数据加密等手段对采集数据进行加密封装,并将加密数据标签上传至区块链网络。调用数据时,需对比封装数据与区块链上的数据标签是否一致。如果不相符,则代表原始数据有过改动,以保证数据的真实性。可见,无需信任的去中心化分布式网络,为省中心化的监测中心普遍存在的安全性低、效率低和成本高等问题提供了解决方案。

With the rapid development of media convergence,digitization and networking,the radio and television industry is experiencing the rapid growth of content flow output,data transmission and user data scale,and the data pressure is increasing year by year.Therefore,the use of advanced data acquisition and processing technology plays a vital role in improving the radio and television monitoring efficiency and data diversion.Based on the decentralized characteristics of blockchain technology,the provincial centralized monitoring center is transformed into a distributed monitoring network,and the monitoring data is stored in local databases.The collected data is encrypted and encapsulated by means of time stamp,distributed consensus and data encryption,and the encrypted data tag is uploaded to the blockchain network.When called,the encapsulated data is compared with the data on the blockchain According to whether the label is consistent,if not,it means that the original data has been changed,so as to ensure the authenticity of the data.The decentralized distributed network without trust provides a solution to the problems of low security,high cost and low efficiency of provincial centralized monitoring center.
