Embodiment

As shown in Figure 1, when the carelessness of the computing machine of commonly using because of the user, and computing machine is not when having secrecy system, as easy as rolling off a log in the short time, capsule information are stolen, and also or secrecy provision imperfect, the stealer can translate and obtains password easily via the anti-group of intrasystem ASCII character.

As shown in Figure 2, the utility model by a receiver 1, a transmitter 2, and software form; Wherein this receiver 1 with USB interface 3 as and the computing machine bridge of linking up, when user 5 when in Windows following times, installed the dedicated secret software of this wireless identification lock, installation procedure can be fit into driver under the Windows in the lump, makes receiver 1 to link up and to control the activation of security software and close via USB interface and secure routine.

Situation one, as shown in Figure 2, receiver 1 and transmitter 2 all the time, receiver 1 and transmitter 2 are the mode with electronic circuit, rely on identical frequency, and launch a confirmation signal with a set time, this confirmation signal can make receiver 1 and transmitter 2 carry out wireless telecommunications by the user from ordering, and is sent by transmitter 2, receiver 1 receives, when if receiver 1 surpasses certain distance with transmitter 2, when then this moment, receiver 1 can't receive the signal of transmitter 2, receiver 1 just activated security software by USB interface immediately, and the function mode of this computer-chronograph can switch to locking mode by Windows originally, this moment, the computer-internal data was promptly protected, be difficult for stealing, as shown in Figure 3, when the user returns computing machine, when receiver 1 receives the signal that comes from transmitter 2, then, automatically switch to window picture H and lock picture G, when the user returns by the locking of receiver 1 via USB interface releasing security software, can be directly computed, to reach the confidential data safeguard function.

Situation two, as Fig. 3, shown in Figure 4, because of user's carelessness or because of other factors, cause receiver 1 of the present utility model wherein to have one not exist with transmitter 2, or both all not the time, do not influence the running of its exclusive secure routine this moment, but because of receiver 1 and transmitter 2 not cause, the user in temporary from the time need the last lock icon of window picture H lower right corner working line, can activate security software, this computer-chronograph presents locking picture G, as shown in Figure 5, in temporarily from after come back to computing machine after, also need input password and remove, after the releasing, computing machine then comes back to window picture H by locking picture G, the user can continue normally to use a computer, and also reaches the function of confidential data protection in the process.

As shown in Figure 2, the locking picture that security software presents is shown in G, F is the warning message hurdle, this is criminal offence to inform the stealer, literary composition can be by the user from ordering in the message, and A, B, C, D, E is the project hurdle, scroll bar all can be pulled out in each project hurdle, have the option more than six kinds in the scroll bar, as: " address; age; password; telephone number; wife's name; blank " etc., this six option names only is the convenient usefulness that explains orally, actual option names can be needed according to self and ordered certainly by the user, and all correspond to A under each project hurdle, B, C, D, the password hurdle of E, input password for the user, but be not that each project hurdle and password hurdle all need setting code, can be by user's demand itself, project hurdle and the password hurdle selected are wherein set, be not that five project hurdles and password all need be set, increase user's elasticity, also reduce its inconvenience greatly, and the stealer is when desiring to steal, at first must in project hurdle five options, select correct option, be input into correct password hurdle with correct password again, state can unlock, so cooperate six kinds of options with five project hurdles, cooperate with password again, it is very little to crack opportunity of success, make that to steal the data opportunity of success through this security software very little, more impossible in the user temporarily from a few minutes in crack success, so just can reach the purpose of confidential data protection.

Particularly, the utility model is a wireless identification lock, its embodiment provides the receiver 1 of computing machine use and the transmitter 2 that the person of being used carries, and be aided with software, to reach the purpose of confidential data protection, below at the action of this receiver 1, transmitter 2 internal circuits, describe with block scheme:

As shown in Figure 6, behind receiving antenna 7 reception signals, leach the signal of basic midband earlier through bandpass filter 8, and amplify 9 amplification signals via a low noise and send into mixer 10 and intermediate-frequency filter 11, but the noise that filtering is unnecessary, and after sending into logarithmic amplifier 12 and data and leaching device 13, can learn this correct signal, send into code translator 16 via 1 bit comparison analyzer 14 again and can correctly solve signal, again from the signal that solves, acquisition wherein identification code and to confirm that identification code 17 is confirmed, if this identification code mistake, then the signal of expression reception is external signal, so do not continued to handle with this signal, if identification code is correct, then send into arithmetic processor 18 and do bidirectional data transfers with usb 19, and carry out data transmission 20 with USB slot 3, wherein 5V operating voltage 21 is required operating voltage of USB work, when signal amplifies by low noise amplifier 9, for avoiding its frequency jitter, cause the malfunction of this circuit, so with an oscillator 151, phase frequency detects 152,1/64 ratio dwindles 153, voltage-controlled oscillating 154, and charge circuit 155 is as a phase-locked loop 15, can effectively pin this frequency of operation and unlikely beating, because this technology is the communicating circuit technology that those skilled in the art are easy to realize, so do not given unnecessary details at this.

As shown in Figure 7, this transmitter 2 at first needs to set 26 by an identification number and is set the identification number, and send into arithmetic processor 25 computings in addition, this arithmetic processor also needs a timer 27 to be assisted, this timer 27 is the indispensable supplementary module of an arithmetical unit, computing finish after just send into scrambler 24 and encoded, just can launch via antenna 22 by amplitude modulation transmitter module 23 after the end-of-encode, antenna 7 with receiver receives again, and as above treatment step in addition, as mechanics of communication of the present utility model.

Fig. 8 and Fig. 9 are the solid appearance of the utility model receiver 1 and transmitter 2, but its receiver outward appearance 28 and transmitter outward appearance 291,292 thereof are a kind of embodiment wherein, with screw 294 sealed these loam cakes 291 and lower cover 292 to form transmitter 2, but the utility model is non-limiting in the receiver 1 and transmitter 2 of outward appearance like this, allly hold circuit board of the present utility model and the person of being easy to carry all can be used as outward appearance of the present utility model, do not limited for the style of outward appearance.
