Abstract
A peep proof simplified cipher input completely discards the multi numbers key input method, changing into single key input, randomly generating numbers between 0 to 9 within equal intervals and showing them on the display.
Description
The invention belongs to computing machine additional input equipment, relate to a kind of simplified cipher input media with peep-proof visual function.
We often need input password in many public arenas, and for example in bank, when depositing, withdrawing money on the ATM, when carrying out stock exchange in securities broker company, we need to input password.The most frequently used cipher input mostly adopts essentially identical code keypad, and 0～9 10 numeric keys and affirmation are set on the keyboard, function keys such as removing.This cipher inputting keyboard is owing to the position of numerical key is fixed, when the user inputs password, when particularly password need repeat to import, the Peeping Tom can judge the password of input from importer's hand shape and input position, thereby brings unnecessary loss to the user.A lot of PIN PAD that Chinese patent is announced, as patent CN2676307Y, CN2676283Y etc. are to adopt shielding mode to realize anti-function of spying in essence, but bulky, operation inconvenience.Patent CN1371038A has adopted key position and the size touch-screen type cipher inputting keyboard of stationary arrangement not at random, can realize the peep-proof visual function better, but still adopt most keyboard modes that volume is relatively large.
At various different drawbacks of PIN PAD in the past, the present invention has designed theftproof simplified cipher input device simple, easy to use, that have stronger confidentiality.
The present invention is as the substitute of ordinary password input keyboard, input unit, and whole device comprises the anti-lens and the common key-press spied on of driving circuit, CPU (central processing unit), display screen and top thereof.It is characterized in that producing at random at regular intervals the numeral between 0～9 and on display screen, show, when the password figure that occur to need, selections＜input key imports a password, and show the password of having inputed with the form of * on display screen.After the input of all password positions finishes, selections＜affirmation〉key with password transmission to computing machine.The present invention has thoroughly abandoned traditional most keyboard input modes, change the singly-bound input mode into, the Peeping Tom can't judge the password of input by importer's hand shape and input position, and the password figure top is mounted with and anti-ly spies on lens, has only the operator in dead ahead just can see the numeral of demonstration clearly.This PIN PAD also is provided with USB interface and RS232 serial line interface, can be connected with PC or other smart machines easily, all can use on all need input the smart machine of password.
Advantage of the present invention is can prevent from effectively to be spied on by the people when the input password and snatch password, and avoids causing economic loss to the user, guarantees the security of user cipher better.
Fig. 1 is the schematic appearance of PIN PAD of the present invention.
Fig. 2 is a PIN PAD main program flow chart of the present invention.
Below in conjunction with accompanying drawing, anti-theft PIN PAD of the present invention is further described and illustrates.With reference to Fig. 1 and 2, the outside of theftproof simplified cipher input device comprises: random digit viewing area 1 and settle above it anti-to spy on lens, input password viewing area 2, function key 3,4,5,6,7, data communication interface 8 and 9.The inside of PIN PAD comprises driving circuit and CPU (central processing unit).In start, reset or the password end of input after, display screen 2 shows information such as " online ", " welcoming to use ".When terminal prepares to receive the password input, show information such as " can input password " by initiating key.Selection＜beginning〉behind the key, display screen 2 begins to produce numeral at interval at random (in once circulating by certain hour, each numeral of 0～9 occurs once at least), the time interval realizes with timer and upgrades password figure in the mode of interrupting, when by speed regulation function key 7, can regulate the time interval that random number produces, when the password figure that needs occurring, selection＜input〉key can input a password, if the password input error, can be by＜cancellation〉key deletes last effective key number.So repeat to finish up to all password figure inputs, select＜determine the input of bond Shu Benci password.CPU (central processing unit) is sent to terminal with the data of being preserved with the communications protocol of stipulating according to the connected mode with terminal.
Claims (2)
1. anti-peeping code input device comprises the anti-lens and the function key of spying on of driving circuit, CPU (central processing unit), RS-232 and USB standard communication interface, digital display screen and essential information display screen, digital display screen top.
2. PIN PAD as claimed in claim 1 is characterized in that abandoning traditional most keyboard input modes, changes the singly-bound input mode into.The random number algorithm produces random number in constant duration, select the required password of sequential combination by singly-bound.
