Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, a mobile smart terminal data leakage prevention safe storage and backup method mainly includes three aspects of two-way identity authentication, transmission and transparent encryption / decryption. The specific implementation methods of each aspect are as follows:

[0036] 1. Two-way authentication

[0037] Two-way identity authentication includes identity authentication running on the mobile smart terminal and identity authentication running on the server side. Implement two-way authentication.

[0038] (1) The identity authentication running on the mobile smart terminal realizes the functions of user registration, identity authentication, and user logout. The identity authentication includes two parts: the server authenticates the user and the user authenticates the server. The detailed implementation i...

Abstract

The present invention discloses a method for leakproof, secure storage and backup of data of a mobile smart terminal. A user of the mobile smart terminal applies for an authority for accessing a cloud server through registration. When accessing the cloud server, after mutual identity authentication between the mobile smart terminal and the could server is passed, an operational authority can be necessarily obtained. For a file that needs to be uploaded by the user, transparent encryption is performed on a content of the file locally to then generate a ciphertext, which is then uploaded; and when the stored file is required to be downloaded, the file is retrieved at the cloud storage server, downloaded to the mobile smart terminal locally, and then recovered to be a plaintext through transparent decryption, i.e., transparent encryption / decryption is automatically completed at the mobile smart terminal locally. The cloud server assigns a storage node to the uploaded ciphertext, stores or backs up the ciphertext file. The file exists in the form of ciphertext in any place other than the local mobile smart terminal. The method of the present invention ensures the user data leakproof.

Description

technical field [0001] The invention belongs to the technical field of computer information security, and in particular relates to a data leakage prevention and safe storage and backup method of a mobile intelligent terminal. Background technique [0002] With the development of the mobile Internet, more and more people use mobile smart terminals for mobile office, mobile payment, real-time communication, etc., and store a large amount of useful data on them, which involve many personal privacy. Although the computing power of mobile smart terminal devices is improving, the storage capacity of mobile smart terminals is limited. As the amount of stored data continues to increase, the storage capacity of the terminal becomes a bottleneck. Therefore, it is an inevitable trend to store the data of mobile smart terminals in the cloud server, but how to ensure the security of the data is an urgent problem to be solved. [0003] At present, the protection for secure transmission o...
