Abstract

A combinative encryption flash disk with two data disks and an encryption system at least for digital data encrypted and accessed via an operating system is characteristic of (1) Function of keeping digital data secret and safe; (2) Consumer'"'"'s reduced cost and a specific plug-in sequence for a promoted secrecy function by two cascaded data disks at least plugged into a single port; (3) Plain interface and simple operation in favor of one user configuring and operating.

Claims

1. A combinative encryption flash disk for digital data encrypted and accessed via an operating system comprising:

Two data disks at least wherein a substrate of the data disk has both an outer surface with a plurality of contact fingers at one end as well as a plurality of adapter fingers at the other end and an inner surface provided with a memory chip at least electrically connected to the contact fingers as well as the adapter fingers;

An encryption system stored in the memory chip comprising;

A public zone at least used to store public digital data;

A private zone at least used to store private digital data;

A public program with both a sequence configure module used to determine a sequence of the data disks plugged sequentially and a capacity configure module used to regulate a relative capacity of the public zone and the private zone.

2. The combinative encryption flash disk according to claim 1 wherein the capacity configure module is provided with a capacity configure interface which is used to regulate a relative capacity of the public zone and the private zone and is exported to an electronic data exchange device.

3. The combinative encryption flash disk according to claim 1 wherein the sequence configure module is provided with a sequence configure interface which is used to decide a sequence of the data disks plugged sequentially and is exported to an electronic data exchange device.

4. The combinative encryption flash disk according to claim 1 wherein the public program comprises a time configure module as one timing mechanism which is used to decide time intervals of both the data disks plugged into the electronic data exchange device and the data disks sequentially plugged each other and is provided with a time configure interface exported to an electronic data exchange device.

5. The combinative encryption flash disk according to claim 1 wherein the public program comprises a password configure module which is used to key in or cancel a password and is provided with a password configure interface exported to an electronic data exchange device.

6. The combinative encryption flash disk according to claim 2, 3, 4, or 5 wherein the capacity configure interface, the sequence configure interface, the time configure interface, and the password configure interface can be integrated into an identical operation interface or any of different operation interfaces for performance of each configure.

7. The combinative encryption flash disk according to claim 1 wherein the public program is installed in a single data disk or distributed in one of a plurality of data disks at least.

8. The combinative encryption flash disk according to claim 1 wherein the contact fingers are compatible to one of the following data transfer interfaces at least such as Universal Serial Bus (USB), Mini Universal Serial Bus (Mini USB), Micro Universal Serial Bus (Micro USB), or External Serial Advanced Technology Attachment (e-SATA).

9. A combinative encryption flash disk for digital data encrypted and accessed comprising an operating procedure shown as follows:

Step 1;

Two data disks at least provided;

Step 2;

Data disks plugged into an electronic data exchange device and sequentially and properly connected each other;

Step 3;

Operation interface enabled;

Step 4;

Relative capacity of the public zone and the private zone regulated via the operation interface'"'"'s capacity configure interface;

Step 5;

Configuration completed.

10. The combinative encryption flash disk'"'"'s operating procedure for digital data encrypted and accessed according to claim 9 wherein a sequence of the data disks, time intervals of the data disks sequentially plugged, and key-in as well as cancel of a password can be regulated or configured via the sequence configure interface, the time configure interface, and the password configure interface respectively after Step 3.
