Problems solved by technology

This method also has obvious shortcomings: not only is the cost high, but it can only be authenticated once when it is first turned on, and real-time monitoring cannot be achieved

Embodiment Construction

[0063] The key technologies and specific implementation methods of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0064] Such as figure 1 As shown, the application scenario of the present invention includes a user's mobile phone or PDA, a Bluetooth adapter and a computer, and the Bluetooth adapter can be a general-purpose USB Bluetooth adapter. The computer equipped with protection software automatically executes the BIOS after booting, and then interacts with the Bluetooth of the user's mobile phone or PDA through the Bluetooth adapter connected to it, obtains the Bluetooth address and IMSI number of the user's device, and waits for the user to enter the PIN code. The user enters the PIN code on the mobile phone or PDA, and the computer calculates the authentication key through a specific algorithm to complete the device authentication between the mobile phone Bluetooth and the computer Bluetooth adapter, as well as th...

Abstract

The invention provides an automatic protecting method for a computer system based on Bluetooth device authentication. In the method, a control program is written in a disk MBR (Master Boot Record), and double authentication of hardware equipment and user identity is realized by combining a Bluetooth wireless transmitting protocol before an operating system is started and using a Bluetooth address, a PIN (Personal Identification Number) code and a mobile terminal IMSI (International Mobile Subscriber Identity) number. In an operation process of the operating system, automatic real-time monitoring is set, the system can be automatically locked and can not be operated once the Bluetooth device of a user deviates from the coverage area of a Bluetooth adapter; and the system can be automatically unlocked and recovered for operation once the Bluetooth device of the user returns to the coverage area.

Description

technical field [0001] The invention is an automatic protection method for a computer system based on bluetooth device authentication, and belongs to the technical field of information security. Before the computer operating system is started and when it is running, through the communication between the Bluetooth device and the mobile terminal, the identity authentication, real-time monitoring and system access control functions are realized to achieve the purpose of protecting the computer system. Background technique [0002] With the increasing degree of informatization, information security is particularly important. Many people think that the security risks mainly come from hacker attacks and virus damage. As long as firewalls and anti-virus software are deployed, it will be safe. However, according to the survey results of the US Federal Bureau of Investigation and computer security agencies, more than 80% of information security risks come from internal rather than ex...
