Abstract
The utility model relates to a new type encrypted keyboard of the terminal input device of metal field in bank, ATM automatic teller machine and credit card measuring device. The encrypted keyboard comprises a press-key which is connected with thesingle chip microcomputer of the controlling part. The surface of the press-key is the digital display module, and the single chip microcomputer of the controlling part is connected with the decoder. The programming the single chip microcomputer and controlling the digital display of the digital display module and the setting value of pressing key. After pressing once or one group of keys, the single chip microcomputer will accordingly change the arrangement of the pressing key value, and the digital display of the digital display module conducts synchronous changes to keep the one to one relationship. In this way, the function of pressing once or one group of keys can realize the immediate change of the arrangement of the press-key, and people around can not judge the factual press-key value according to the position of the key which the figure presses, thus realizing the function of encrypting the keyboard and reaching the aim of improving the safety of the code.
Description
Technical field
The utility model relates to bank, ATM Automatic Teller Machine, the novel Encryption Keyboard of the terminal input equipment of financial fields such as POS device is the novel Encryption Keyboard by single-chip microcomputer and digital display module (charactron or liquid crystal digital module) and button formation.
Technical background
At present, in bank, the ATM Automatic Teller Machine, in the POS equipment, the input of user's password is finished by the keyboard digital input.And common keyboard is not considered the cryptography issue that keyboard is imported at present.The user is when using keyboard input password, and the position judgment of finger went out button when people on every side was easy to import according to user's keyboard, thereby can obtain the password that the user imports.Like this, the security the when user inputs password can't be effectively protected, and the case that the lawless person steals user cipher and then theft user account by observation user key-press finger position also happens occasionally.Therefore, there is the low problem of security performance in common keyboard.How to develop high degree of safety, the people around can't observe user's keyboard input content, and is easy to use again, and the keyboard of cost economy is the emphasis problem of terminal input area research.
The content of utility model
Current, bank, ATM Automatic Teller Machine, the ordinary numbers keyboard that uses in the outer input equipment field such as the terminal of POS equipment etc. is owing to exist the low problem of security performance, make the user have very big potential safety hazard when keyboard input password, user's password is stolen by lawless people when being everlasting the keyboard input.In view of this, how to be bank, ATM Automatic Teller Machine, terminal input equipments such as POS equipment provide a kind of security to have the keyboard of encryption function, make the user when keyboard is imported, others can't judge the keyboard of button content from key position, and use reliably, conveniently, with low cost, the utility model wound is ground the motivation place just.
The purpose of this utility model can be by following realization:
This Encryption Keyboard comprises button, and button connects the control section single-chip microcomputer, is digital display module by strong surface, and the control section single-chip microcomputer is connected with code translator.
The utility model is further characterized in that code translator comprises display decoder and gated decoder; Display decoder is 7 sections display decoders, connects each digital section of digital display module respectively; The output of gated decoder connects the display digit in the digital display module respectively; Gated decoder is 4 to 6 line code translators, and digital display module can be electronic digital displays such as light emitting diode nixie display, crystal digital coding on the display.
The utility model passes through mcu programming, and the cooperation by other modules, the number that can control digital display module simultaneously shows and by the strong value of setting, thereby can make digital show digital and corresponding one by one by the strong value of setting, and digital display module is shown by the setting value of being good for.Each time or behind each group button, single-chip microcomputer changes the arrangement by strong value immediately, and the number of digital display module shows and carries out synchronous variation, keeps concerning one to one.Like this, can realize whenever that by once by strong, by the function that strong arrangement just changes immediately, people on every side can't judge the reality of pressing by strong value from the finger key position, thereby has realized the function of Encryption Keyboard, has reached the purpose of raising cipher safety.
It is simple to the utlity model has (1) circuit, and volume is little, low in energy consumption; (2) keyboard shows is provided by charactron, not only eye-catching, and also can normally use than the dark place at light; (3) good confidentiality, other people are difficult to see password except password input people; (4) cost is low, and big promotional value is arranged.
Description of drawings
Fig. 1 is a control circuit structural drawing of the present utility model.
Fig. 2 is a display circuit structural drawing of the present utility model.
Content of the present utility model
Below in conjunction with Fig. 1, Fig. 2 embodiment illustrates the utility model, the utility model single-chip microcomputer U1, can adopt P87LPC768 is core controller, also can adopt any device with logic control function, adopt an IO mouth of single-chip microcomputer, as P0.0-P0.7 as the input port, press figure connected mode and button SW1, SW2 ... SW16 links to each other, read by strong input, another IO mouth, as P1.0-P1.8 as delivery outlet, be used for and display decoder U2,4 to 16 line gated decoder U3 link to each other: wherein preceding four of delivery outlet link to each other by display decoder (as: 741s49BCD sign indicating number to 7 section display decoder), in order to produce the digital control signal that shows, back four corresponding tens words 0 of gating signal that produce 10 display modules by 4 to 16 line gated decoders (as 74145) respectively of delivery outlet, 1,2 ... 9 (LED1 to LED10), the numeral that is used for controlling digital display module writes.
In sum, the utility model has reached the purpose of maintaining secrecy, and has improved the safety of financial circles, and is very little to the change of existed system simultaneously, realizes that cost is low, has good popularization value.The utility model can be applied in bank, and security etc. need carry out the occasion of authentication to the user, by this Encryption Keyboard, can avoid the leakage of user password information.Also do not find same product in China at present, obviously this be one novel, progressive and the design of use value arranged.The above is specific embodiment of the utility model and the principle used, if the equivalence of making according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that instructions and accompanying drawing contain yet, all should be in scope of the present utility model, explanation hereby.
