Embodiment 1
[0035] like figure 1 , figure 2 As shown, this embodiment provides a context-aware cloud data privacy protection method based on crowdsourcing evaluation, including the following steps:
[0036] S1. The client generates a context dictionary according to the context information of the data file, and then the client sends the generated context dictionary to the server as a sensitive query list;
[0037] S2. Query and establishment of data sensitivity value: After receiving the query list from the client, the server queries each situation in the situation list in the data sensitivity value database. If the situation has been evaluated, it returns a data directly Sensitivity value to the client; on the contrary, if it has not been evaluated, the server will design the uploaded situational information as a crowdsourcing task, invite users to evaluate the sensitivity of the data together, get the data sensitivity value, and then pass the crowdsourcing evaluation The obtained data...

The purpose of the present invention is to provide a situation-aware cloud data privacy protection method based on crowdsourcing evaluation, which can provide users with data privacy protection services in the cloud data sharing situation. This method can perceive the context of user data sharing, including data category, content category, data owner, etc., and provide different data sharing strategies according to different scenarios to effectively protect user data privacy; This method integrates the collective wisdom of cloud users, based on project response theory, objectively evaluates from a system perspective and comprehensively and effectively evaluates data sensitivity through interactive crowdsourcing, further improves the accuracy of data privacy and security risk assessment, and provides users with data sharing scenarios in the cloud. under Data Privacy Protection Services.
Description
technical field [0001] The invention belongs to the field of data privacy security, and in particular relates to a context-aware cloud data privacy protection method based on crowdsourcing evaluation. Background technique [0002] In the era of mobile Internet and cloud computing, users can enjoy a variety of cloud application services, including taxi, food delivery, mobile payment, etc., by providing identity information to register. However, while users enjoy various convenient application services, they also face the danger of privacy data leakage. For example, the data of 320,000 users of American cable company Time Warner was stolen, the passwords of more than 65 million email accounts on Tumblr were leaked, and more than 167 million accounts of LinkedIn were publicly sold on the black market. The feeling is increasing day by day. Ordinary users cannot protect their own data security, and do not even realize that behind their identity data and behavior data of enjoyin...
