为了解决大数据环境下,传统数字化信息发布系统存在的响应效率低以及抗风险性能差的弊端,设计基于云计算与风险评估的数字化信息发布系统,系统由数据层、支撑层以及应用层构成,分析了系统的业务流程,并对系统的综合信息管理、风险评估交流以及信息发布共享功能进行了分析.给出了系统中多媒体播放终端模块、信息发布管理模块的设计和实现过程.分析基于云计算的信息安全风险评估流程,实现信息发布系统安全风险的有效评估.实验结果说明所设计的信息发布系统,具有较高的响应效率和抗风险性能.%In the large data environment,the traditional digital information publishing system often does not consider the risk of information publishing,and its corresponding efficiency and risk resistance capacity become poor.Therefore,this paper designed a new digital information publishing system based on cloud computing and risk assessment model.Firstly,we designed the overall structure of system.This system consists of data layer,support layer and application layer.Then,we analyzed the work flow of system in details;secondly,this paper proposed the risk assessment algorithm based on the theory of risk perception.Combined with cloud computing environment,we calculated cloud matching degree of data.Combined with the matching degree,we designed the evaluation model to realize the effective evaluation of security risk in information dissemination system.Thus,we built the digital information publishing system,realizing the digital information publishing under low risk.Experiments show that the designed information publishing system could solve the disadvantages of the traditional method,which has high response efficiency and strong ability to resist risks.
