Description
Technical field
Invention relates to information safety system and its method of operating of computing machine.In the time that sensor is the preset range of the connection device that is distributed in, computing machine is carried out a screen protection pattern, to prevent that unwarranted user from using computing machine, and is positioned near connection device when sensor.User does not need to input the first cognizance code, has strengthened security and the more convenient operation of information in computing machine.
Background technology
The function of computer is varied, essential in daily routines of today.Because computing machine provides information storage easily.People preserve secret information on computers conventionally.In order to prevent that unwarranted user's access is stored in the confidential information in computing machine, user protects them by a lot of different modes.The conventional method that protection is stored in the information in computing machine mainly comprises smart card.Fingerprint recognition system or the basic input/output (BIOS) of operator password.
Use the method for smart card, comprise after smart card is inserted to computing machine and just can sign in to network.But this method is at booting computer or while waking screen protection pattern up and unsafe.Therefore.Unwarranted user still can operating computer, even without smart card, although cannot sign in to network.This shows, in computing machine, the protection of canned data is inadequate.
In addition, fingerprint recognition system can be used on computing machine, and the fingerprint of identification fixed-line subscriber, only when the authentic user of identification just can operate computing machine.But the hardware cost of fingerprint recognition system is high.
The third method, BIOS comprises the protection of setting operation password.It is characterized in that, the password of described user's input is used for connecting computing machine, and this computing machine can operate only when the cipher authentication of input is correct.But, when computing machine just in use, BIOS need to or not again to input password, anyone can use computer.Understandable from description above; method does not above have method to guarantee the safety of computer; in use, the computing machine of the Windows operating system that screen protection program creates adds more protection, and the time that user can arrange one-period is moved the screen protection of idle running computer.During for cancellation screen protection, user must input username and password, to prevent unwarranted user.But each user leaves this computing machine and is longer than Preset Time section.The title that user must input and password are again and again.In addition.The password that user need to remember, and the input message of taking time, just cause another trouble.
Therefore, how to have become important problem in order to solve above-mentioned defect, in the supplier in this field.
Summary of the invention
The object of the invention is to comprise a microprocessor at a connection device.Microprocessor, is characterized in that, described connection device is connected respectively to connecting interface and transmitting element.The processing unit of described sensor is connected to a transmission interface.When connection device is to be connected to computing machine via connecting interface, and the insertion connection device of sensor.Between connection device and sensor, generate the second authentication code initialization.Therefore,, when sensor is not during in predetermined connection device scope, computing machine is carried out a screen protection pattern, to prevent that unwarranted user from using computing machine.In the time that sensor is positioned at the preset range of connection device, user does not need to input the first cognizance code, to avoid repeatedly inputting the complicated process of the first cognizance code.Strengthen security and the more convenient operation of information in computing machine.
