The 3rd, the change optical circuit is linked to each other with the corresponding control circuit of the equipment of need input password, when equipment enters the input password prompt, trigger immediately and become optical circuit work, thereby send rate of change to the code keypad interface and be higher than the interference illumination light of peeping camera light sensitivity inherent regulation rate, because dark variation of illumination light causes that the variation of cryptographic key panel illumination exceeds the dynamic range of camera light sensitivity, make the application drawing picture of peeping the camera shooting can't differentiate details, can't obtain password; And the illumination light of being sent out is because change frequency is higher than the frequency of people's physical efficiency identification, and human eye can't change perceived, so can not influence operator's operation.
Described illuminating lamp is the LED lamp, and the light that described LED lamp is sent directly or by light guide member is radiated on the code keypad.
Of the present inventionly prevent to use the method for camera snooping password need can be used on the finance device of input card password, as ATM, mass transit card Recharging Machine, public water electricity charge automatic charger etc.
Beneficial effect of the present invention:
Series of advantages such as the present invention has solved the technical barrier that prevents to utilize the camera stealing passwords by technological means, can prevent trouble before it happens, and has good concealment simultaneously, is easy to realize, tamper-proof, cost is low.
Description of drawings
Fig. 1 is the present invention's concrete synoptic diagram of using on ATM.
Fig. 2 is the electrical schematic diagram that matches with Fig. 1.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, 2.
A kind of method that prevents to use the camera snooping password, it may further comprise the steps:
A lighting window at first is set above code keypad, and illuminating lamp is installed in lighting window, the light that this lighting window sends can directly be aimed at code keypad, also can be by being radiated on the code keypad after the light guide member refraction; Illuminating lamp can adopt visible lights such as flashlamp, white light, LED, also can adopt light sources such as infrared light with strong interference effect, ultraviolet light;
Secondly, illuminating lamp is linked to each other with the change optical circuit,, make camera can not obtain desirable illumination so that can when the user inputs password, send the illumination light of variation fast; When having adopted infrared light or ultraviolet light, can connect variation, also can discontinuously change, disturb as long as the infrared or ultraviolet luminous energy of being sent out produces camera review;
The 3rd, the change optical circuit is linked to each other with the corresponding control circuit of the equipment of need input password, when equipment enters the input password prompt, trigger immediately and become optical circuit work, thereby send rate of change to the code keypad interface and be higher than the interference illumination light of peeping camera light sensitivity inherent regulation rate, because dark variation of illumination light causes that the variation of cryptographic key panel illumination exceeds the dynamic range of camera light sensitivity, make the application drawing picture of peeping the camera shooting can't differentiate details, can't obtain password; And the illumination light of being sent out is because change frequency is higher than the frequency of people's physical efficiency identification, and human eye can't change perceived, so can not influence operator's operation.
