Data security protection method of safe mobile storage equipment

Abstract

The invention belongs to the data security field of mobile storage equipment, in particular to a data security protection method of safe mobile storage equipment, which is used for solving the problems of data security of the mobile storage equipment when the mobile storage equipment is crosswise used among different host computer environments. The safe mobile storage equipment adopts a single-equipment and multi-data view design so that the same safe mobile storage equipment provide a single or a plurality of different data views according to the different applied external host computer environments (different safe environments or different unsafe environments). The different data views correspond to different physical storage zones or logical storage zones isolated from each other. The safe mobile storage equipment invention has the benefits advantages that the safe mobile storage equipment adopts the single-equipment and multi-data view design, realizes the data ferry of the storage zones in the unsafe environments through a special safe browser in a safe environment and automatic identification design on external host computer systems in the unsafe environments and adopts an encryption mode to store data in safety mobile storage equipment.

Description

technical field [0001] The invention belongs to the field of mobile storage device data security, and in particular relates to a data security protection method of a secure mobile storage device for solving the data security problem when the mobile storage device is used in cross-use between different host environments. Background technique [0002] With the continuous advancement of mobile storage technology, mobile storage devices (such as mobile hard disks, U disks, etc.) It is convenient to share and exchange data between them. [0003] However, the use of mobile storage devices has also brought many hidden dangers to people's work and life: [0004] 1. Accidental disclosure of confidential data [0005] If an enterprise or individual stores confidential documents or personal privacy and other confidential data on a mobile storage device, once the mobile storage device is lost or the mobile storage device is used on a host infected with a Trojan virus, it may cause acc...

AI Technical Summary

Problems solved by technology

[0005] If an enterprise or individual stores confidential files or personal privacy and other confidential data on a mobile storage device, once the mobile storage device is lost or the mobile storage device is used on a host infected with a Trojan virus, it may cause accidental leakage of confidential data

[0006] 2. Illegal copying of confidential data

[0008] 3. The spread of viruses and Trojans caused by cross-use of mobile storage devices

[0010] In recent years, many of the above-mentioned incidents have occurred, causing huge losses to enterprises and individuals

In order to solve the hidden dangers brought by mobile storage devices, many types of secure mobile storage devices have appeared on the market, but these secure mobile storage devices mainly use software or hardware encryption to store and access data on the device. Security measures that require simple authentication only solve the problem of accidental disclosure of confidential data, but cannot solve the problem of illegal copying of confidential data and the spread of viruses and Trojans caused by cross-use of mobile storage devices

[0011] Based on the shortcomings of the above-mentioned existing mobile storage devices in the accidental disclosure of confidential data, illegal copying of confidential data, and the spread of viruses and Trojan horse programs caused by cross-use of mobile storage devices, the inventor has developed a "Data Security Protection Method for Secure Mobile Storage Devices"
