Abstract: Aiming at the data security problems existed in industrial chain coordination Software as a Service (SaaS) platform,the data security model for industrial chain collaborative SaaS platform was proposed,and the formalized description,framework and implementation process of the proposed model were given.Based on transfer secure module and storage secure module respectively,the security of data transmission and storage was implemented.Through the theoretical and experimental evaluation,the proposed model could meet the data security requirements of industrial chain collaborative SaaS platform,and the impact on overall performance of platform was relatively small.
