Abstract
The present invention relates to a warning function operating method for a portable computer. An external device or a component or a function of portable computer inside is used to undertake key work, and then signals are generated by relative circuits of a key so as to cause an inbuilt controller to know the portable computer is locked or not. When the inbuilt controller knows the portable computer is locked, the external inbreak mechanism is started by the inbuilt controller. In addition, when the external try / broken is discovered, a warning/ alarm function is started, and relative subsequent movements are also started. Thus, the portable computer is caused to have the guard mechanism of the warning function by the present invention so as to achieve the aim of security information protection in the portable computer.
Description
Technical field
The present invention relates to a kind of portable computer, and particularly related to a kind of How It Works of alarm function of portable computer.
Background technology
At present, portable computer (for example being notebook computer) is more and more general, in the future the stage of more possible every one can have a machine.Yet, because carry-on data transmission science and technology makes rapid progress especially, the situation that may have confidential data to leak then.Because present portable computer does not have the mechanism of any defence, so as long as several minutes other people just can take the data of classified papers away and not be found.Therefore, how to make portable computer have the mechanism of defence, steal confidential data wherein, just become one of researchist's urgent problem to prevent other people.
Summary of the invention
The present invention proposes a kind of How It Works of alarm function of portable computer, be the embedding controller (embeddedcontroller that cooperates in the present portable computer, abbreviation EC) function, utilize the input of keyboard, mouse interface or even power switch all necessary through embedding the characteristic of controller, add the cooperation of some switches, reach and make portable computer have the mechanism of the strick precaution of alarm function.
The How It Works of the alarm function of portable computer of the present invention, this portable computer have one and embed controller, and this embedding controller has one and takes precautions against outside invasion mechanism, and described How It Works comprises the following steps:
1) provide a key, a signal that sends by this key, and make this embedding controller learn whether lock;
2) when this embedding controller being learnt lock, this embedding controller can start this strick precaution outside invasion mechanism;
3) judge whether to suffer outside attempt/the invasion; And
4) when suffering outside trial the/when invading, can start caution/alarm function.
The present invention utilizes assembly or the function in external device (ED) or the portable computer inside to serve as " key (key) " work, the signal that produces of the interlock circuit by key then embeds controller and learns whether portable computer locks and make.When the embedding controller learns that portable computer is locked, embed controller and can start the outside invasion mechanism of taking precautions against.Moreover, if find to suffer outside trial the/when invading, can start caution/alarm function, and the subsequent action of being correlated with.Therefore, the present invention can make portable computer have the strick precaution mechanism of alarm function, and reaches the purpose of the confidential data in the protection portable computer.
Description of drawings
Fig. 1 is the synoptic diagram of the portable computer of a preferred embodiment of the present invention.
Fig. 2's is the process flow diagram of How It Works of alarm function of the portable computer of a preferred embodiment of the present invention.
Embodiment
As Fig. 1 is the synoptic diagram of the portable computer 10 of a preferred embodiment of the present invention.As shown in Figure 1, portable computer 10 comprises embedding controller 102, computer system 104, other related system 106, supply unit 108 and key (key) 110.Wherein, embedding controller 102 is the runnings in order to control computer system 104 and other related system 106, and it has the outside invasion of strick precaution mechanism.And key 110 is the signals by the interlock circuit generation of key 110 in the portable computer 10, and makes embedding controller 102 learn whether portable computer 10 locks.Wherein, key 110 can for example be assembly or the function in portable computer 10 inside.For example, key 110 can be a button in the portable computer 10, when pressing this button, can make to embed controller 102 and learn that portable computer 10 locked.Or key 110 is assembly or the function in the external device (ED).For example, key 110 can be a button on the infrared remote controller, and when pressing this button, the infrared ray of being launched can be received by portable computer 10, embeds controller 102 and learns that portable computer 10 locked and make.Be the process flow diagram of How It Works of alarm function of the portable computer of a preferred embodiment of the present invention as shown in Figure 2.In this How It Works, the work that at first can utilize assembly in external device (ED) or portable computer 10 inside or function to serve as key 10, the signal that produces by key 110 interlock circuits in the portable computer 10 then embeds controller 102 and learns portable computer 10 whether lock (as step S202) and make.Learn that portable computer 10 is unlocked if embed controller 102, then can continue normal operation (as step S204).If learn when portable computer 10 is locked, then embed controller 102 and can start the outside invasion mechanism (as step S206) of taking precautions against and embed controller 102.Wherein, take precautions against outside invasion mechanism and comprise and prevent to make portable computer 10 starts, prevent to make the keyboard input/use in the portable computer 10, use keyboard input to prevent other people; Prevent to make the mouse input/use in the portable computer 10, use mouse input to prevent other people; Basic input input-output system (BIOS) in the notice portable computer 10 carries out the precautionary measures, is revised to prevent BIOS; And other the precautionary measures.Then, embed controller 102 and can judge whether portable computer 10 suffers outside attempt/ invade (as step S208).Judge that portable computer 10 does not suffer outside attempt/the invasion, then can return step S202 if embed controller 102.If judge that portable computer 10 has suffered outside attempt/the invasion, then can start caution/alarm function (as step S210) and embed controller 102.Afterwards, can carry out relevant subsequent step (as step S212).And the relevant subsequent step comprises and makes portable computer 10 shutdown, closes the screen of portable computer shutdown 10 or carry out certain specific program.Furthermore, the relevant subsequent step more comprises the action of attack or even self-destruction.
In preferred embodiment of the present invention, key 110 is to be coupled to a pin that embeds controller 102.And the signal that the interlock circuit of key 110 produces can be a calibration signal, but not as limit.
In sum, the present invention utilizes assembly or function in external device (ED) or the portable computer inside to serve as " key (key) " work, make by interlock circuit then to embed controller and learn whether portable computer locks.When the embedding controller learns that portable computer is locked, embed controller and can start the outside invasion mechanism of taking precautions against.Moreover, if find to suffer outside trial the/when invading, can start caution/alarm function, and the subsequent action of being correlated with.Therefore, the present invention can make portable computer have the strick precaution mechanism of alarm function, and reaches the purpose of the confidential data in the protection portable computer.
