Secure use method of privacy data in cloud computation

Abstract

The invention relates to a secure use method of privacy data in cloud computation. The secure use method is characterized by comprising the basic steps of classification of the privacy data of a user, detection of an exposed chain and the key privacy data, protection of the discrete privacy data and protection of the continuous privacy data. Through detection of the exposed chain and the key privacy data in the first stage and recombination with the exposed chain and the key privacy data as root nodes in the second stage, the continuous privacy data are converted into the discrete privacy data, and then personal privacy information of the user is protected. The requirement of the user is met through decomposition and combination of the privacy data without exposing a discrete privacy data chain of the sensitive privacy information of the user, and therefore the method can effectively guarantee the secure use of the privacy information of the user in a multiparty interactive sharing and evolving system.

Description

technical field [0001] The invention belongs to the technical field of user privacy information protection of interactive sharing and evolution systems, and in particular relates to a method for safely using private data in cloud computing. Background technique [0002] With the emergence of big data, cloud computing, as a computing platform, provides conditions for adapting to the evolving system structure and real-time processing of big data. Fast scaling, charging based on use, and a series of features such as virtualization, distribution, multi-tenancy, and service outsourcing. As a new computing model for serving users, it has become a research hotspot in the industry. However, the cloud architecture is complex and usually requires cross-organizational service composition, and different organizations and heterogeneous service participants bring huge challenges to meet user privacy data security and privacy. The intermediate operation process of the cloud service provid...

According to the analysis of the US Electronic Privacy Information Center (EPIC), Google's new privacy policy only considers the protection of data, but does not provide settings and management for the use of private data and the exposure of various products, which cannot correctly reflect the user's privacy. privacy needs and may conflict with local laws

In September 2014, Apple's iCloud service lost a large amount of private data of users due to data inconsistency between the end user and the server.

[0004] To sum up, the existing methods are relatively effective for the security of end-to-end information transmission, but in the environment of multi-party service interaction, sharing and evolution, especially in the cloud computing environment, it is impossible to guarantee the security of user privacy information. safe use
