Data security storage method

Abstract

The invention provides a data security storage method. The data security storage method comprises the following steps of: dividing a local encryption space from a local storage space and a cloud encryption space from a cloud storage space according to the set of a user; when data is stored into the local encryption space by the user, randomly generating a secret key, and encrypting the data according to the secret key, so as to obtain encrypted data; synchronously storing the secret key and the encrypted data into the cloud encryption space; when the local encryption space is opened by the user, generating an access request for accessing the cloud encryption space, randomly generating a first verification code, and sending the first verification code to a predetermined third-party terminal; receiving a second verification code currently input by the user, and judging whether the second verification code is same as the first verification code; if the second verification code is same as the first verification code, entering the cloud encryption space, and otherwise, refusing the entry of the cloud encryption space. By virtue of the data security storage method, the data storage security can be improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data security storage method. Background technique [0002] Cloud storage space is used to provide users with online file storage, access, backup, sharing and other file management functions. Through the network disk, no matter where the user is, as long as he can connect to the Internet, he can manage the files stored online in the network disk through the mobile terminal. [0003] However, since the use of cloud storage space will be connected to the Internet, there is data confidentiality and security. At present, the method adopted in the prior art is to encrypt the account of the cloud storage space. However, this method not only increases the complexity of the user's login account, but also has the risk of being stolen when facing risks such as hackers. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a...
