Abstract

The invention discloses a system encryption-based data protection method and device, and aims at solving the problem that data protection method in the prior art is relatively bad in safety. The method comprises the following steps of: receiving an access password input by a user; judging whether the access password corresponds to a first operation system or not; if the access password does not correspond to the first operation system, judging whether terminal equipment is connected with preset hardware authentication equipment or not; if the terminal equipment is connected with the preset hardware authentication equipment, carrying out identity authentication on the preset hardware authentication equipment according to authentication information; if the authentication passes, decrypting a disk driving file corresponding to an encrypted hidden virtual disk space in the terminal equipment according to file encryption/decryption information, so as to obtain the encrypted hidden virtual disk space; and decrypting the encrypted hidden virtual disk space according to the file encryption information, and logging in a second operation system, wherein the second operation system is installed in the encrypted hidden virtual disk space, and local data needing protection is stored in the second operation system.

Description

technical field [0001] The present application relates to the field of information security, in particular to a data protection method and device based on system encryption. Background technique [0002] With the advent of the information age, data security issues have received more and more attention. [0003] In practical applications, users generally encrypt local data to protect local data and prevent local data from being stolen by others, such as providing password authentication to protect data in compressed packages through compression tool software, or using encryption software to encrypt encryption protection, etc. [0004] However, the above-mentioned data protection methods are less secure. For example, when criminals invade the terminal equipment where the local data is located, the criminals may use decryption software to track and decompile the encrypted data, and the encrypted data may be deciphered, or After criminals invade the terminal device where the l...
