Abstract: To improve the storage mechanism to provide a general privacy protection service, a data protection model based on edge computing is presented. The original data collected by wireless sensor networks is differentiated by privacy computing algorithm on edge servers. A small amount of core data is stored on edge servers and local servers,while other data is transferred to the cloud for storage. Based on the model,even if the data stored in the cloud is leaked,the original data cannot be recovered,so the privacy of the data can be ensured. The differential storage method reduces the data sent to the cloud and decreases the communication cost and storage cost. Both theoretical analyses and a large number of experiments have proved the effectiveness of the proposed method.
