Data protection method, client and system

Abstract

The invention relates to a data protection method, a client and a system. The data protection method comprises the following steps that 1, required data is downloaded from a server according to selection of a user; 2, the data downloaded from the server is saved as local data; 3, the saved local data is processed locally; 4, data obtained after local processing is completed is uploaded back to theserver; 5, the local data is deleted. According to the data protection method and system, by means of the mode that data processing is conducted locally and the data is uniformly stored on the server, a person only needs to download a required data file to the local from the server, the data transmission quantity is small, and the network cost is low; after data processing is completed, data is deleted from the local and is not stored in the local, and then the person is not afraid of losing a host, and data leakage is avoided; the data obtained after processing is completed is uploaded to the server to be uniformly stored, and management is convenient.

Description

technical field [0001] The present invention relates to data processing technology, and more particularly, to a data protection method, client and system. Background technique [0002] In practical applications, enterprise personnel often need to travel around with hosts with sensitive data. Although the data in the host can be protected by power-on passwords and data encryption software, once the host is lost or attacked by hackers, it is very difficult to It is easy to cause data leakage and loss, resulting in losses. For this reason, various completely diskless network solutions appear in the prior art, but the network transmission data volume is large, the speed is slow, and the network cost is high. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a data protection method, client and system with high security and low network cost, aiming at the above-mentioned defects of the prior art. [0004] In order to s...

[0002] In practical applications, enterprise personnel often need to carry hosts with sensitive data to travel around. Although the data in the hosts can be protected by power-on passwords and data encryption software, once the hosts are lost or attacked by hackers, it is very difficult. Easy to cause data leakage and loss, resulting in loss

For this reason, there are various network solutions based on completely diskless in the existing technology, but the network transmits a large amount of data, the speed is slow, and the network cost is high
