Abstract

The invention provides a privacy protection method for big data in cloud computing. The method includes the steps of setting a plurality of authentication servers in a cloud storage platform, and conducting secret key distribution and character authentication transaction processing by class; maintaining a global user character list, wherein the authentication servers set an authorization reading policy and a constraint control policy. The privacy protection method for the big data in the cloud computing enhances safe reading policy control of environment and policy constraints, reduces computing costs of writing users on the premise of ensuring safety, and meets application demands of various cross-cloud cross-class data policies.

Description

technical field [0001] The invention relates to secure cloud storage, in particular to a privacy protection method for cloud computing big data. Background technique [0002] The cloud data storage platform stores computing resources in a configurable shared pool of computing resources, and reads computing resources through a convenient and on-demand network. Security has become a key issue restricting the development of cloud storage. Cloud storage service providers provide services in cloud storage, while users are in a passive position, resulting in a serious asymmetry in information control. Cloud storage transfers information to cloud storage service providers, but enterprises themselves can no longer fully control the information and storage details of cloud service providers; cloud storage is aimed at multiple users, and cloud service providers cannot provide information to owners in consideration of their own security. Present key information in storage. On the ot...
