Access method for website database

Abstract

The invention provides an access method for a website database. The access method comprises the following steps: encrypting a plaintext of user data with the determined valid period, distributing and saving the encrypted plaintext to a distributed storage network, compacting a ciphertext into a self-deleting file and then saving the self-deleting file in a storage server cluster portal site by a data owner; obtaining the self-deleting file and a ciphertext set from the storage server cluster portal site and the distributed storage network and restoring to obtain original user data by an authorized user. The invention provides the access method for the website database. According to the access method, a complex private key of an encryption algorithm is effectively managed, a hierarchical safety and granularity access control strategy is provided, safe self deletion of the data beyond the valid period is realized, and no extra manual intervention is needed.

Description

technical field [0001] The invention relates to network data storage, in particular to a website database access method. 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 deletion. Existing so...

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
