Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0032] The network disk data security system is mainly composed of two parts: server and application terminal. Its main functions include:

[0033] The server is responsible for downloading application terminals, managing user data, encrypting and decrypting algorithms, recording encrypted file names, storing and storing encryption and decryption keys, and other functions.

[0034] The application terminal needs to be installed on the terminal used by the user, such as a personal computer, a smart phone, etc. The main functions are responsible for encrypting and decrypting files, obtaining encryption and decryption keys from the server, managing encryption algorithms, and obtaining user data, etc.

[0035] Such as figure 1 as shown, figure 1 The file encryption process of the network disk data encryption...

Abstract

The invention discloses a system and a method for realizing network disk data security, which aim to protect security and privacy of network disk data and information. According to the system and the method, a user installs a terminal application of the system on a terminal, the terminal application encrypts sensitive data which needs to be transmitted to a network disc for storage, and the sensitive data is transmitted to the network disk for storage after the encryption is completed; when the user needs to extract the data, the original encrypted data is downloaded from the network disk and then decrypted and restored into an original data file by means of the terminal application, thus, a security and secrecy mechanism and a security and secrecy service are provided for the sensitive data stored in the network disk.

Description

technical field [0001] The invention relates to the technical field of network disk security, in particular to a system and method for realizing network disk data security. Background technique [0002] With the development of the Internet, the use of network disks is becoming more and more common. There are personal network disks, enterprise network disks, free network disks and paid network disks, and the space of network disks is getting larger and larger. More and more people use the network disk to store video, audio, text, pictures and other files. Program developers even hand over the source code developed to the network disk for storage and backup. At the same time, the network disk can also be used to share files stored in the network disk with friends. on the content. The network disk provides great convenience for the exchange and storage of data information. But the network disk also has certain security risks. If the server that provides the network disk ser...
