A computer with data security function and its data encryption and hiding method

Abstract

The invention provides a computer with a data privacy function and a data encryption and hiding method thereof. The computer comprises a computer host, a solid-state drive and an identity information input device, wherein an identity information collection and man-machine interface module is built in the computer host; the solid-state drive is connected with the computer host; the identity information input device is connected with the identity information collection and man-machine interface module; the solid-state drive comprises a public storage region and an encrypted storage region; the identity information input device is used for collecting the identity information of a user; the identity information collection and man-machine interface module is used for receiving the identity information collected by the identity information input device, processing the identity information and sending the processed identity information to the solid-state drive; the solid-state drive receives the identity information sent by the identity information collection and man-machine interface module and authenticates the identity information, and the computer can display, read and write the encrypted storage region only after the identity information authentication is passed, and otherwise, only the public storage region can be displayed, read and written. When the technical scheme is adopted, the relying on the computer host and other peripheral equipment is avoided, and a security computer based on hard disc data encryption and hiding can be conveniently built.

Description

technical field [0001] The invention relates to the field of computer data storage and data security, in particular to a computer with data security function and a data encryption and hiding method thereof. Background technique [0002] For a long time, the security of computers (commonly known as computers) has attracted much attention. Whether it is economic or military, whether it is a country, an enterprise or an individual, and whether it is a computer equipment manufacturer, designer, or user, there are computer security issues. aspects of product demand. There are many ways to build a secure computer. One of the important directions is the security protection of computer hard disk data, that is, by encrypting the hard disk data, unauthorized operations or illegal cracking can be prevented, thereby forming a secure computer. . [0003] The security protection of computer hard disk data includes two aspects: storage area data encryption and hiding. Traditional hard d...

AI Technical Summary

Problems solved by technology

Hardware-based data encryption overcomes some shortcomings of the module method, such as completing data encryption and decryption operations by itself, but there are still some defects: because the encryption and decryption of the entire hard disk data affects the startup and operation performance of the computer, it is only suitable for low-speed Mechanical hard disk; users need to configure an additional encryption board, which is expensive; the application range is narrow, and cannot be used for small computer equipment such as notebook computers and tablet computers; in addition, with computer hardware equipment (such as CPU, motherboard, hard disk, etc.), peripheral communication There are performance upgrades in terms of protocols and operating systems, and there are also upgrade issues in the performance and compatibility of encryption boards, etc.

In general, the hidden partition at the application level is not thorough enough, and theoretically it can be cracked by an illegal intruder who is familiar with the file format of the operating system

[0006] In short, the existing computer hard disk data encryption and hiding technologies have problems or defects such as occupying CPU resources, relying on the operating system, relying on external encryption and decryption boards, reducing the read and write speed of the hard disk, hidden dangers of cracking, and limited user use.
