A Flow-Based Architecture

This chapter introduces a flow-based architecture that can be used to achieve a balance between privacy protection and behavior accountability. A self-certifying identifier is proposed to efficiently identify a flow. In addition, the mechanism of the cooperation between a delegate and a registry, which we have briefly introduc1ed in Sect. 2.3.3, is integrated into the introduction of the flow-based architecture to show the relationship between the delegate and the registry and the working process of proposed mechanism in practice.
