Data storage and access method and system

Abstract

The invention discloses a private data security storage and authorized access method and system. Identity authentication is carried out on a visitor; identity information is read, the identity of a visitor accessing the data can be ensured to be legal; whether a visitor is a data administrator or not is judged; data imported by a data administrator can be screened out; and storage space is saved;the secret key or the certificate is not transmitted in the network, so that a secret key or a certificate can be prevented from being leaked in a network transmission process to ensure the security of data storage; the identity information of the visitor and the range of the data requested to be accessed are sent to the data administrator, and whether the data is decrypted or not is judged according to the auditing result of the data administrator, so that the data authorization access method which is completely controlled by the data administrator is realized, and the method and the system are particularly suitable for private data security of a mobile internet environment.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a data storage and access method and system. Background technique [0002] The level of informatization development has become an important symbol to measure the degree of modernization of a country. With the increasing informatization of various industries, data security issues have become more and more important to users. Currently, the most common way of data protection is to protect data in plaintext Existence, access control requires an account or an electronic certificate to access, but this data protection method, once the data on the server is stolen, will lead to data leakage. In fact, in recent years, large-scale data leakage incidents have It is not uncommon, so there is a need for a storage and authorized access method that can better protect data security. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose ...
