Detailed Description
The application discloses mechanical type developments password peep-proof keyboard is through setting up and the refraction angle of light on the change keyboard on the change button to the realization is avoided the peeper to the discernment of the biological characteristic of staying on the keyboard when inputing and is peeped in order to obtain the password.
Of course, it is not necessary for any particular embodiment of the invention to achieve all of the above advantages at the same time.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
The following further describes the present application with reference to the drawings.
A small code breaking liquid crystal display screen is added on each key of the mechanical keyboard, and when a consumer is prompted to input a password each time, different random arrangement can be realized by using a specific algorithm through the 0-9 number keys, so that even if the key is pressed, the risk of password leakage cannot occur.
As shown in fig. 2 and 3, the code breaking liquid crystal display 7 arranged under each key is connected with the microcontroller 3 on the PCB2, and the microcontroller 3 includes a key display control module 4 for controlling the content displayed in the code breaking liquid crystal display arranged under each key.
The key display control module 4 controls key values of the code breaking display screens under the N keys on the keyboard, and controls key contents displayed on the code breaking display screens under the N keys by randomly changing kinetic energy according to the sequence of the display positions of the key values of the N keys on the keyboard.
For example: randomly selecting key values of a first key from the key values of N keys on the keyboard, namely randomly selecting one key value from the N key values as the key value of the key, transmitting the selected key value to a broken code display screen driving chip, and further controlling the display content of a broken code display screen under the key; then, the key value of the second key is randomly selected, i.e. from the remaining N-1 key valuesRandomly selecting one key value as the key, transmitting the selected key value to a broken code display screen driving chip, and further controlling the display content of the broken code display screen under the key; and so on until the Nth key selects only the remaining 1 key value as the key value of the key. Thus, the N key values can be randomly arrangedAnd (4) seed preparation.
By the mode, the dynamic change of the keys of the mechanical keyboard is realized by the random arrangement mode, and the possibility of leakage of input contents is further reduced.
Preferably, in order to further reduce the possibility of password leakage, the application further adds a peep-proof layer 8 on each key 6 added with the small code-breaking liquid crystal display 7. After the peep-proof layer 8 is added, the content on the broken code liquid crystal display screen 7 on the key 6 is only visible within a certain angle, and the angle is invisible when reaching a certain fixed value, so that people beside cannot see the number of the key even if the angle is not shielded by hands.
As shown in fig. 2, the keyboard comprises a Printed Circuit Board (PCB)2, N keys 6 are disposed on the PCB, a barcode-breaking liquid crystal display 7 is disposed on each key 6, and a peep-proof layer 8 is disposed on the barcode-breaking liquid crystal display 7. The privacy layer 8 may be made of a material that refracts light, for example: a polarizing material.
Preferably, in order to achieve the best peep-proof effect, an angle adjusting frame 9 can be arranged below the peep-proof layer 8, and the angle adjusting frame 9 is used for adjusting the visual angle of the peep-proof layer 8 so as to ensure that other people except the input person is invisible within the safety range.
The adjusting frame 9 is connected with an angle control module 5 in the microcontroller 3 on the PCB2, and the angle control module 5 adjusts the adjusting frame 9 according to the calculation so that the peep-proof layer 8 obtains the optimal visual angle theta.
The calculation method of the angle control module 5 is as follows:
wherein,is the wavelength of the light wave, x is the current plane offset of the privacy layer 8, θ0Is the current viewing angle of the privacy layer 8.
Therefore, the angle control module 5 readjusts the visible angle of the peep-proof layer 8 through the adjusting bracket 9 (θ - θ)0)。
