Problems solved by technology

[0027] Moreover, different data processing system hosts have quite different protection and permission methods for data, and some even have none at all, which is extremely detrimental to data security
Additionally, existing access permission methods are too simplistic to meet increasingly complex data protection requirements

Embodiment Construction

[0138] Method of the present invention can be implemented like this, and existing hard disk device is improved as follows:

[0139] 1. Use the file system to organize and manage the storage space inside the external storage device;

[0140] 2. Change the access method based on "block" between the existing hard disk device and the host to an access method based on file system operation commands;

[0141] 3. Add permission access control;

[0142] 4. Add log (Log) records;

[0143] 5. Perform encryption / decryption processing;

[0144] Specifically, the storage space in this embodiment is located inside the storage device, and the external storage device has a storage medium access device; the external storage device is designed to: use the NTFS file system to organize and manage the storage space, and use EFS to encrypt; store The space can be divided into 3 volumes (partitions), and the 3 volumes (partitions) are recommended to use the same file system or different file syst...

Abstract

A storage method and device for a data processing system, the method and device are used to better control data exchange, organize and manage storage space by using a file system inside an external storage device, and provide a data processing system host access interface at the file system level , and conduct access permission review, so as to ensure the absolute control of the data by the external storage device, ensure data security, avoid unauthorized data access, and also avoid the potential active spread of viruses through the external storage device. Through access log (Log) records and data encryption, users can better understand and master the data being accessed and better prevent potential data leakage, destruction or loss. The external storage device can also be used as a portable host to read and write other storage devices, which facilitates portable applications.

Description

Technical field [0001] The present invention relates to external storage device technology, specifically, the present invention provides a novel storage method and device for better control of data exchange. [0002] Background technique [0003] External storage devices are widely used for data exchange in data processing systems. At present, common external storage devices mainly include the following categories: [0004] 1. External memory with various interfaces, such as hard disk, electronic hard disk, flash disk, etc.; [0005] 2. Replaceable storage media storage devices with various interfaces, such as floppy drive, Zip drive, MO drive, CD-ROM drive, etc.; [0006] 3. All kinds of hard disk boxes (CD boxes), card readers, etc., they use additional memory as storage space; [0007] Common interfaces for external storage devices are: [0008] IDE (Integrated Drive Electronics / Electronic Integrated Drive) * interface [0009] SCSI (Small Computer System Interface...
