A background processing method of website database

Abstract

The invention provides a website database background processing method. The method comprises steps as follows: a data owner distributes and stores encrypted plain-texts of user data with valid periods confirmed in a distributed storage network after encrypting plain-texts, compresses cipher-texts into self-deleting files and then stores the self-deleting files in a storage server cluster portal website; an authorized user acquires the self-deleting files and cipher-text sets from the storage server cluster portal website and the distributed storage network to restore original user data. With the adoption of the website database background processing method, complex private keys of an encryption algorithm are effectively managed, a classification security and granularity access control strategy is provided, safe data self-deletion after the valid period is exceeded is realized, and additional manual intervention is not required.

Description

technical field [0001] The invention relates to network data storage, in particular to a background processing method of a website database. Background technique [0002] With the widespread popularization of cloud computing technology and various cloud services, people gradually rely on synchronizing their own data, documents, etc. to free network servers or cloud data centers for use in multiple places or in personal groups shared. However, these data or documents stored on the network or cloud often contain user data, such as confidential emails, personal information, business secrets, and Internet Cookies, etc., causing users to worry that they may be compromised or leaked, while network services or cloud Such concerns have been escalated by various new intrusions and legal pressures on the service. [0003] The most straightforward way to achieve this is to delete this user data after expiration. However, deleting data from local or web pages does not achieve true de...

AI Technical Summary

Problems solved by technology

However, deleting data from local or web pages does not actually delete

Existing solutions also have limitations to varying degrees: there are complex private key management and private key distribution issues; within the validity period of user data, fine-grained access control mechanisms cannot be provided; data containing confidential information or data Implement hierarchical security protection; the solution itself may not be perfect

[0004] Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed
