Abstract

The present invention relates to a method with the functions of virtual space and data encryption and invisibility that stores a file data as encrypted code through an encryption mechanism. Data can be read through an embedded data storage device only. In the mean while, the invention enables a specific path of data stored on the data process apparatus can be concealed. The invention utilizes dual security for enhancing data security and confidentiality to achieve the object of data security management.

Claims

1. A kind of method with the functions of virtual space and data encryption and invisibility is applied to an embedded data storage device to protect files through an encryption procedure and conceal data of the embedded data storage device and a data process apparatus;

the method consists of the following steps;

Installing the embedded data storage device into a data process apparatus;

Establishing at least a virtual database on the data process apparatus;

Setting the virtual database through the user end;

Storing a file in the virtual database;

Detecting if the data process apparatus is still equipped with the embedded data storage device; and

Concealing a specific path of the file displayed on the data process apparatus.

2. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the embedded data storage device is connected to the data process apparatus through a connection interface.

3. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 2, wherein the connection interface is an IEEE 1394.

4. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 2, wherein the connection interface is a USB interface.

5. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the data process apparatus can be selected from any computer controlled hardware platform, such as a PC (Personal Computer), a NB (Notebook), or a PDA (Personal Digital Assistant), a mobile phone or a handheld data process apparatus.

6. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the step of establishing at least a virtual database on the data process apparatus further consists of the following steps:

Partitioning an area through a storage space of the data process apparatus; and

Establishing an objective path of the virtual database in the area.

7. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 6, wherein the storage space can be a HD (Hard Disk), and the area is comprised of logical (virtual) memory blocks.

8. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the data process apparatus, at the step of establishing at least a virtual database in the data process apparatus, can be replaced with the embedded data storage device.

9. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 8, wherein the embedded data storage device can establish at least a virtual database;

the steps consist of;

Partitioning an area through a storage space of the data process apparatus; and

;

Establishing an objective path of the virtual database in the area.

10. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the step of setting the virtual database through the user end further consists of the following modes:

a loaded/unloaded mode, a space management mode, a password mode, and a backup/restore mode.

11. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 10, wherein the loaded/unloaded mode is to enable or disable the user end to use the specific virtual database.

12. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 10, wherein the space management mode enables the user to change the space size of the virtual database.

13. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 10, wherein the password mode provides a rescue password for security controlling, if the user loses the embedded data storage device;

the mode further limits specific rescue times and enters into the read-only status of the virtual database.

14. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 10, wherein the backup/restore mode enables data required by the user to be made a backup on the data process apparatus;

the restore model enables data to be restored from the data process apparatus to the virtual database.

15. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the step of storing a file in the virtual database further consists of the following steps:

Encrypting the file through an encryption mechanism;

Copying the specific path through the virtual database; and

Moving the specific path to the storage space.

16. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the step of concealing a specific path of the file displayed on the data process apparatus is to remove the specific path stored to the storage space.

17. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the specific path is information and journey of the file left on the data process apparatus.

18. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the file can be a specific item processed by an application program.

19. The method with the functions of virtual space and data encryption and invisibility in accordance with claim 1, wherein the embedded data storage device can be one of a portable storage device, an IC (Integrated Circuit) Card, or a smart card.
