Depending on the request that the user presses the button and actively prints the authentication activity, it may be used to handle non-instinctive authentication activities to identify the authentication. After USB flash disks were added to RFID tags, what mobile office and mobile storage meant was expanded. Mobile storage devices can be employed in PCs and can be used as electronic certificate centers, such as USB flash memory disks, door security systems, car alarm systems, etc. in all everyday life.

The implementation according to the invention is as follows;

(a) dividing the data block of the flash memory into a system guide area and a data storage area; (b) matching the system guide region with a magnetic guide data format of a CIOS standard device; (c) construct a released schedule of the data block to match the magnetic data format; (d) check compliance secondary storage through the data exchange interface and the BIOS to complete the formatted decision processing; (e) Set the flash memory as a guide device.

9 and 10, the externally mounted hardware divides the storage device into several areas, and each area is divided as follows.

Public area (a): The public area provides a read / write area that is open to the user. The user is not authorized to write or read the disc symbol of the protected area.

Protective area (b): The action is similar to that of a hard disk. One executable document is executable in the public domain and after the correct code is entered, the data can be read and accessed.

Encryption area (c): The user must execute the document by providing the correct code in this encrypted area in order to read and access the stored data. If the code is correct, the protected area will give the user a disk symbol. Otherwise, the user can only use the public area. If the code number is wrong, the encrypted area is modified and the user's code number remains secret.

The lock of the computer is as follows.

After the device has been plugged in for a long time in USB matching, the device may be added with a computer protection lock function through editing of the hardware or loading a running program. Until the user is plugged into the device, the PC cannot be started, initialized or run as part of a program. This device can be used to record the usage history of the computer, including all activities after login.

There are two types of implementation methods, namely in the BIOS; Devices with two sets of code numbers and these two sets of numbers may be used simultaneously or one may be selected. For a fixed code number, the PC is generally initialized after passing the standard device only when the POST allows it to be compiled with it in the BIOS so that the BIOS reads and accesses the PID and VID of the present invention for the PID and VID. Can only be.

For various code numbers; The user can store the preferred number in the device, the storage medium becomes the EEPROM or the secret area of the password or flash memory, and after the PC is turned on, the BIOS automatically enters the code number for user authentication and confirmation. The PC will operate normally. The user can change the code number by means of BIOS interface or internal application program.

If the user has already loaded the drive program, the system will automatically open the code number window to the user and enter the code number to compare with that on the USB electronic disk. If the code numbers are not the same and the user continues to use the computer, the computer will be turned off by blocking all access ports, external serial ports, USB ports, and PS / 2 port parallel ports.

If the preset device is used as a PC guide disk, the device is inserted into a USB slot. This provides great storage capacity and speed for reading and writing.
