Problems solved by technology

[0004] 1. The traditional cloud storage data privacy protection mechanism based on simple encryption technology brings relatively large system overhead and cumbersomeness in the actual data operation process, and once hackers crack it, the data will be leaked or lost;
[0005] 2. The reputation and qualifications of the cloud storage service provider cannot guarantee that users can boldly and confidently put the data in the space provided by the cloud storage provider for data storage;
[0006] 3. The storage of data in cloud storage services needs to be based on the widely used Internet network, because data storage is based on network transmission, and the probability of being intercepted during transmission also increases the risk of data

Embodiment Construction

[0034] A data security protection method based on data segmentation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] as attached figure 2 , image 3 As shown, the present invention provides a data security protection method based on data segmentation, and its specific protection steps are:

[0036] 1. Set up a cloud storage system. The cloud storage system includes a client and a cloud. The client is responsible for monitoring and capturing local system operations;

[0037] 2. Users who have purchased the cloud storage service can use the cloud storage system to store data. When the client user needs to upload data and requests the system to store data, the data block will be stored in the corresponding physical device according to the distribution of the main control server. The specific storage steps are as follows:

[0038] On the client side is the client system, which is responsible for monitoring and c...

Abstract

The invention provides a data safety protection method based on data partitioning. According to an employed strategy, different data needing storage at a client end are reasonably partitioned into great and small data blocks, and the great and small data blocks are respectively deployed in local and non-local cloud storage systems. Compared with the prior art, the data safety protection method based on data partitioning can effectively prevent a malicious user or a cloud storage administrator from carrying out illegal stealing and tampering of privacy data of users, provides more choices for safety of different data for users and has advantages of improved system flexibility, strong practicality and easy popularization.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a data security protection method based on data division. Background technique [0002] In recent years, incidents such as Google data leaks and cloud service system data security of companies such as Microsoft and Amazon have been questioned have further aggravated the industry's concerns about data security, reliability and credibility of cloud applications; The core root of existing data security problems is the separation of data management rights and ownership. The data belonging to the user is outsourced to the cloud storage provider, and the cloud storage provider obtains priority access to the data. Facts have proved that cloud storage providers do not have sufficient evidence to convince users that their data is stored and used correctly due to various risks such as internal personnel negligence, hacker attacks, and system failures leading to failure of se...
