Problems solved by technology

Sending and entering extraction codes is very inconvenient for clients to share files with other clients
There are also a small number of network hard disks with poor security. Any account on the server can view and download files of other accounts through search engines.

Embodiment 1

[0039] The invention discloses a network hard disk backup file data security system based on a virtual disk. The system includes a network hard disk server end and a client end communicating with each other.

[0040] Using the method and system of the present invention, each client can log in to the network hard disk server after verification of the account name and password, and can read the backup files of its own friends, but does not have the authority to read and modify files of non-friends. Has read and modify permissions on its own files.

[0041] The user encrypts and transmits the files that need to be backed up locally to the network hard disk server end through the client, and sets other users' access rights to their own backup files; saves the user's rights information in an access rights index table (such as figure 1 shown). Preferably, the user can respectively set the access rights of other users to each backup file of the user through its client, such as a cer...

Embodiment 2

[0056] This embodiment discloses a network hard disk backup file data security method based on a virtual disk.

[0057] The client can set the friends who can share the backup files as ordinary users, set itself as a super user, and set all non-friends as guest users, which prevents every client on the network hard disk from being able to read the backup files. Take operations to ensure that backup files are not obtained by illegal users.

[0058] The operation of the local network disk client is:

[0059] (1) The operating system loads the driver of the virtual disk.

[0060] (2) Set the accounts of super users, ordinary users and guest users, determine the access rights of these three types of users to the backup files (including readable, unreadable and modifiable three kinds of rights), and form an access right index table.

[0061] (3) The files and index tables to be backed up are transmitted to the server on the network disk through 128-bit SSL encryption.

Abstract

The invention discloses a network hard disk backup file data safe system and a method based on a virtual disk. The system comprises a network hard disk server end and client ends which are mutually communicated. The method comprises the following steps that a user encrypts local files needed to backuped by the client ends, transmits the files to the network hard disk server end, and sets the access permission of other users to self backup files; the server end stores the backup files of the client ends, and controls the access permission of each user to the backup files in the virtual disk according to a access permission index table of the users; when the user with the access permission accesses the backup files on the server end, a virtual hard disk driving program is transmitted to open the virtual disk, and the backup files are opened in the virtual disk, so that the user can access the virtual disk. The invention can protect the safety of the backup files uploaded to the network hard disk server by the client ends; and compared with the current pickup code control access method, the safety and the convenience are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of computer security, and relates to a data security system, in particular to a virtual disk-based network hard disk backup file data security system; at the same time, the invention further relates to a virtual disk-based network hard disk backup file data security method . Background technique [0002] With the popularization of computer and network technology in social life, users need to work, study or handle affairs in different places, so they hope to be able to obtain pre-stored files at any time. Traditional hard disks and currently commonly used mobile hard disks, U disks, etc. have hidden dangers of insecure user data and disadvantages of inconvenient use. In this case, the network hard disk came into being. [0003] Network hard disk, also known as network U disk, network disk, is an online storage service launched by some network companies, providing users with functions such as file storage, a...
