In cloud computing, user functional requirements are satisfied through service composition. However, due to the process of\ninteraction and sharing among SaaS services, user privacy data tends to be illegally disclosed to the service participants. In this\npaper, we propose a privacy data decomposition and discretization method for SaaS services. First, according to logic between\nthe data, we classify the privacy data into discrete privacy data and continuous privacy data. Next, in order to protect the user\nprivacy information, continuous data chains are decomposed into discrete data chain, and discrete data chains are prevented from\nbeing synthesized into continuous data chains. Finally, we propose a protection framework for privacy data and demonstrate its\ncorrectness and feasibility with experiments.
