Abstract:

In order to avoid the benefit loss of certain individuals in the benefit competition set due to the sensitive information leakage resulting form the flow of service structure information in all nodes, and to ensure the parallel operation of nodes with high information security, this paper defines a dynamic Web service flow, proposes the nonsensitiveTree and sensitiveTree algorithms to separate sensitive variables from the dependence expression of simultaneous place, and designs dependence expression trees for different objects. Afterwards, a synchronous agent is constructed to manage the information publishing, thus implementing the management of dynamic service flow with security. Experimental results show that the proposed system can not only manage the dynamic operation butalso guarantee the information security of services of each benefit individual.
