Research on public opinion risk control of major public health problems based on blockchain traceability technology

重大公共卫生事件伴随的社会舆情问题,给国家防控造成了巨大的干扰与影响。在信息传播途径中,谣言借助网络传媒实现迅速传播,因此从源头以及传输渠道对信息进行研判,就能够有效切断虚假舆情的传播。研究基于区块链溯源技术,为重大公共卫生事件中,公安以及防疫部门提供舆论信息源头以及信息传播途中的变动情况,从而达到对重大公共卫生事件的舆情把控。对社会公众而言,既能了解真实重大公共卫生事件信息,做好防控,又能够免受谣言的侵扰。

The public opinion issues associated with major public health incidents have caused tremendous interference and impact on national prevention and control.In the public opinion communication channels,the cost of making rumors is low,and rumors can quickly spread the information through network media.Therefore,limiting the spread of information from the source and transmission channels can effectively cut off the spread of false information and opinions.This research is based on the blockchain tracing method to provide public security and epidemic prevention departments with the source of public opinion information and changes in the way of information dissemination during major epidemic events,so as to achieve control of public opinion.As far as the public is concerned,they can not only understand the real information of major public health incidents,prevent and control them,but also avoid the intrusion of rumors.
