Abstract
The invention provides a starting up lock method for protecting personal information. According to the method provided by the invention, control program of a USB (universal serial bus) main engine controller based on BIOS (basic input output system) environment is stored in a hiding section of 0th channel of 0th head of hard disk. When an applied main engine is started, the control program of the USB main engine controller is loaded when a system enters a MBR (master boot record) stage, the USB main engine controller on a mainboard is taken over, and a USB Key inserted into an USB port is detected and identified, so that the starting up lock function of the applied main engine is realized, and the starting up lock method for protecting the personal information is realized.
Description
Technical field
The present invention is about realizing using the method for computer lock, and the entering MBR stage is carried out USB Key authentication after using launch computer specifically, thereby realizes the method for the start lock in the start-up course.
Background technology
The raising of Along with computer technology, personal computer (application computer), particularly laptop computer applications R benefit are general, and many people can be some to the hard disk the inside of the very useful data storage of individual or company at computer.How to prevent that data important in the computer from illegally being stolen, prevent that the problem of the relevant application computer security of any computer of opening oneself of disabled user and so on from receiving people's attention with benefit, particularly the business people.People hope and can protect the computer of oneself not encroached on by the handlebar electron key, so the notion of USB Key has just produced, just become the problem that the booting computer lock needs solution of using and how USB Key is carried out identification very much.After present application booting computer lock still just is confined to the starting up and gets into Windows operating system, USB Key is carried out identification, if identification error then pin computer screen.A kind of like this method is also dangerous, and the disabled user can move below Windows through some little software, thereby cracks screen protection.On this meaning, it only is to have realized the screen protection lock, and is not real start lock.
Can realize effectively that in using the launch computer process stage of starting up lock function has two:
1. protect in the BIOS stage;
2. protect in the MBR stage.First kind of scheme need be led and pull business men adds USB Key authentication in bios program code, and the specific group of the not conference of mainboard business men that program code is cherished word such as gold among the BIOS EPROM to be needs use computer security removes to revise BIOS.And in the MBR stage, this moment, not load operation system can't move all kinds of programs that crack, and authentication code and usb host controller driver can leave in the hard disk, therefore can extraordinary realization use the booting computer lock function.
Summary of the invention
For above purpose; The invention provides a kind of start locking method of realizing protecting personal information; This method comprises: write based on the usb host controller driver under the BIOS environment, this driver can the compatible UHCI.OHCI that uses main flow on the computer main board at present be the usb host controller of standard;
Load the usb host controller driver in the MBR stage, take over the usb host controller of BIOS control and come, and USB Key is detected and authentication;
Checking finishes the back from the control of new recovery bios program to usb host controller, makes it to continue to support USB mouse, USB keyboard, USB floppy disk etc.
Description of drawings
In claims of present patent application, pointed out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, can better understand of the present invention about structure and implementation method with and purpose, characteristic and advantage.
When Fig. 1 has the trivial function of start of the present invention, use the start-up course of computer
The practical implementation method
In following detailed description, described specific details and the present invention has comprehensively been understood so that provide.Yet the professional and technical personnel will appreciate that the present invention also can use other similar details to implement.
When using the booting computer lock function and installing, will have MBR code based on usb host controller control program under the BIOS environment and USBKey authentication function and deposit the inside, space that the 1st sector, O the 0th road of disk begins in;
After using launch computer, get into the MBR stage, take over usb host controller based on usb host controller control program under the BIOS environment;
Drive through usb host controller, detect USB Key and USB Key is used special-purpose usb data transfer instruction, carry out authentication;
If detect with authentication through from of the control of new recovery bios program, get into the start-up course of normal load operation system to usb host controller, if not through continue detection.
Though here declarative description certain this characteristic of the present invention and a kind of implementation method, for the professional and technical personnel, many modifications, replacement will occur, change and raise and imitate replacement.Therefore, protection scope of the present invention is as the criterion by the scope of appended claim.
Claims (6)
1. start locking method of realizing protecting personal information, this method may further comprise the steps:
When using the booting computer lock function and installing, the MBR code that will have a U9B Key authentication function deposits the inside, space that the 1st sector, the 0th the 0th road of disk begins in;
After using launch computer, get into the MBR stage, take over the usb host controller of BIOS control based on usb host controller control program under the BIOS environment:
Through the usb host controller control program, detect USB Key and USB Key is used special-purpose usb data transfer instruction, carry out authentication;
If detect with authentication through recover the control of bios program again to usb host controller, get into " start-up course of the load operation system that F is normal, if not through continue detection.
2. a kind of according to claim 1 start locking method of realizing protecting personal information is characterized in that: will have the inside, the 0th space that the 1st sector, O road begins that deposits disk based on the MBR code of usb host controller driving and USB Key authentication function under the BIOS environment in;
3. a kind of according to claim 1 start locking method of realizing protecting personal information is characterized in that: get into the MBR stage, take over the usb host controller of BIOS control based on usb host controller control program under the BIOS environment;
4. like the said a kind of start locking method of realizing protecting personal information of claim 3, it is characterized in that: said based on usb host control seize by force device control program support UHCI under the BIOS environment, the usb host controller of OHCI;
5. a kind of according to claim 1 start locking method of realizing protecting personal information is characterized in that: through the usb host controller control program, detect USB Key and USB Key is used special-purpose usb data transfer instruction, carry out authentication;
6. a kind of according to claim 1 start locking method of realizing protecting personal information; It is characterized in that: if detect and authentication through then recover the control of bios program again to usb host controller; Get into the start-up course of normal load operation system, if come through continue to detect.
