Description
(1) technical field
The present invention relates to a kind of a kind of password burglary-preventing method of bank ATM machine theft preventing method, particularly bank ATM machine.
(2) background technology
Along with reform and opening-up, expanding economy, financial services industry is also developed fast, is being extensive use of various types of cash withdrawal machines, and the depositor extracts cash according to the needs of oneself from cash dispenser.Millions of have been reached at China's cash dispenser.
The ATM (automatic teller machine) appearance that prior art is used is different, but inner structure and operation principles basically identical ATM (automatic teller machine) are similar to computer, general configuration with common computer, basic hardwares such as existing mainboard, CPU, hard disk, internal memory, CD-ROM drive, floppy drive, USB interface and network interface; Operating system software is arranged again.Also disposed some at hardware aspect and be applicable to the peripherals of automatic drawing business, as card reader, code keypad, display, cash-out device, printer etc.; Aspect software, write and moved some and be applicable to the software of automatic drawing business, be used to receive depositor's input, carry out communication, carry out the service logic judgement and drive corresponding apparatus carrying out corresponding action etc. with bank server.Therefore, technically, all assemblies all are to drive corresponding apparatus by business logic processing software by operating system to finish corresponding action.
Process software withdraw the money accordingly by initial: begin, inquire about number of the account, query the balance, judge whether abundance, remaining sum is enough then paid and record, then refusal operation that Sorry, your ticket has not enough value.Develop and increased differentiation later on to password, such as, the process that existing cash dispenser is withdrawn the money is: 1. holder's plug-in card; 2. card reader reads the magnetic track information in the card, wherein comprises information such as card number, judges whether this magnetic track information is legal; If illegal, then continue; Otherwise enter step 4; 3. to the magnetic track information mistake stick into that row is corresponding to be handled, as gulp down card and point out the holder to apply for card again etc.; 4. the holder inputs password; 5. ATM (automatic teller machine) is delivered to bank server in the lump with the encrypted message of the magnetic track information that read and holder's input, and whether bank server is correct according to the information password check that provides; If incorrect, then continue; Otherwise enter step 7.; 6. point out holder's password mistake, re-enter password; If continuous 3 input password mistakes then gulp down card; Otherwise continue; 7. the holder imports Withdrawal Amount: 8. ATM (automatic teller machine) is delivered to bank server in the lump with the Withdrawal Amount information of the magnetic track information that reads and holder's input, whether bank server has the enough amount of money according among the validation of information account who provides, if 7. insufficient in amount then returns step; Otherwise continue; 9. cash dispenser is told paper money; 10. cash dispenser moves back card.Structure and operational process by above-mentioned ATM (automatic teller machine) can make things convenient for, correctly take out the debt that the depositor has deposited in.
Some technical scheme is dissatisfied to above prior art situation, for the security that improves cash dispenser has proposed " the automatic discrimination alarm system of a kind of true or forge code of ATM (automatic teller machine) " patented claim scheme, password according to user's input is verified, and is optionally verified according to described user and input the pseudo-code that password generates automatically; Warning device is screened device automatically with described true or forge code and is connected, and the checking result who is used for screening automatically according to this true or forge code device makes the processing of whether reporting to the police.This system has improved the security of cash dispenser greatly, and can send alerting signal and take corresponding gate inhibition's measure when find dummy letter.But, above technical scheme all be based upon the input be under the prerequisite of dummy letter, because the development of hi-tech, the technical merit of theft crime activity also improves in development, often can from medium such as newspaper, radio station, TV, learn that some lawless persons steal the password of depositor when depositing and withdrawing, treat that the depositor leaves after, with steal or the bank card that duplicates insert cash dispenser again, input depositor's password is stolen money.
The cryptographic methods that they steal the depositor is a Direct observation, perhaps by mode indirect observations such as mirror, wireless probes, perhaps on the keyboard of password input, set in advance sensing device, treat to extract the marking password that stays again after the depositor leaves, what the lawless person obtained is holder's true password, prior art comprises that above-mentioned application for a patent for invention part also can't stop the generation of this type of theft password, makes the depositor lose very big being difficult to again and takes precautions against.
(3) summary of the invention
On the bank ATM machine, be provided with and spy on device even the purpose of this invention is to provide a kind of lawless person, even on cipher inputting keyboard, be provided with the theft preventing method that copy device also can't be obtained true password.
Purpose of the present invention is solved by following technical scheme:
A kind of password burglary-preventing method of bank ATM machine is characterized in that:
Insert magnetic card;
ATM judges whether magnetic track information is legal, as does not conform to rule and do illegal processing, as the legal road program that then enters down;
By the position ordinal number of at least one of the automated randomized generation of ATM, on the display screen of ATM, show institute's rheme ordinal number by " special " key prompting requirement;
The input password, and by the described requirement of the display screen of ATM, ordinal number is pressed " special " key in the position of described prompting;
ATM judges that whether the position ordinal number that " special " key is pressed in institute's input information and true password and requirement conforms to, and changes corresponding down-stream over to for conforming to or not conforming to.
Further, described " special " key is " skipping " key.
Further, described " special " key is " space " key.
Further, the figure place that the automated randomized generation of described ATM is replaced is 2/10ths to four of total password figure place, takes into a method or gives up a method rounding to a position the decimal occasion occurring.
Further again, the figure place that the automated randomized generation of described ATM is replaced is two.
Further, described magnetic track information does not conform to rule and moves back card or gulp down card and handle.
Adopt the technical program, even the lawless person obtains holder's card number, it is also of no use to lie in wait for the password of having obtained holder's input, because the lawless person does not know real password, the password of holder input is the password that the figure place that generates at random according to cash dispenser software and the prompting of the character on this have been replaced, and when the holder used next time, instruction is change at random, therefore the lawless person can't know real password, can't steal debt.Even if the lawless person takes the card that duplicates to remove to try password, successful probability is minimum, can be identified very soon in the cash dispenser password identification program of prior art, is in time reported to the police and catches.
Beneficial effect of the present invention, no matter the lawless person adopts any technical measures, can't directly obtain real password,, very easily expose the stealer identity on the contrary and be hunted down if utilize the password that directly obtains holder's input to go to try out, to steal the debt probability very negligible.
(4) description of drawings
Fig. 1 is the operational flow diagram of a kind of embodiment of the password burglary-preventing method of bank ATM machine of the present invention;
Fig. 2 is the operational flow diagram of the password burglary-preventing method of prior art bank ATM machine;
Fig. 3 is the structural representation of prior art bank ATM machine.
(5) specific implementation method
Further describe structure of the present invention below in conjunction with accompanying drawing.
A kind of password burglary-preventing method of bank ATM machine: insert magnetic card; ATM judges whether magnetic track information is legal, as does not conform to rule and do illegal processing, as the legal road program that then enters down; By the figure place of at least one of the automated randomized generation of ATM, reach the numeral that described figure place is replaced, and described information is shown in ATM on display screen; Information input password by described replacement requirement; ATM judges that institute's input information requires whether to conform to true password and replacement, changes corresponding down-stream over to for conforming to or not conforming to.
The numeral of described replacement is the natural number in 0 to 9.ATM cipher inputting keyboard for present use is 0 to 9 natural number, therefore, and preferably described natural number.
The figure place that the automated randomized generation of described ATM is replaced is 2/10ths to four of total password figure place, takes into a method or gives up a method rounding to a position the decimal occasion occurring.Total bit preestablishes too big, can cause input trouble, has increased the exploration success again too for a short time, and such as only getting one, then possibility is 1/10, therefore, should determine according to risk and operation ease.
The figure place that the automated randomized generation of described ATM is replaced is two.ATM commonly used at present is six figure place passwords, and it is proper therefore getting two.
Described magnetic track information does not conform to rule and moves back card or gulp down card processing, perhaps other respective handling.
On existing bank ATM machine enchashment program, add a step, at holder's plug-in card and after to be judged magnetic track information be legal, when the holder will input password, delegation's instruction can appear on the screen of ATM, for example: " please first of password; second key entry ' space ' ", the total bit that the display screen prompting is replaced, the double figures that is this example is predefined by ATM, " first; second key entry ' space ' " this statement is chosen by the automated randomized generation of ATM computer software, similarly also have: please the 3rd of password, the 5th makes key entry ' space ' key or the like into, this data-storing is in computer, like this, if original client's password is 123456, the client be input to password on the ATM must be ' space ' ' space ' 3456, perhaps 12 ' space ' 4 ' space ' 6, ATM will be inputed the data of code data and former generation and storage and former holder's password compares, if it is identical then confirm that password is correct, if the password and the display screen prompting that stay in bank with former holder require to replace, the difference of change then is judged to be false card, give gulping down card or moving back processing such as card by the program of former establishment, above ' space ' key also can change into and point out ' skip ' key or other special keys, employing ' space ' key or ' skip ' key, just on common keypad, all have, can utilize, as key effect is too easily to adopt other.
If have the lawless person to adorn camera, known that the password of card number and client input is also of no use, because the lawless person does not know real password in the shelter.The lawless person takes the card that duplicates to go to try the words of password, for the words of double figures 0 to 9 data pilot scale spy, probalility of success only is 1/100, and when the client used next time, instruction is change at random, therefore, so the words of stealing not only can not steal debt, the pilferage identity that easily sticks one's chin out on the contrary is if adopt the existing ameliorative measure of prior art, subsidiary warning, gate inhibition mechanism, the easier quilt of lawless person hits.
Even the lawless person spies on and obtain the password of holder's input, but do not know real password, can't correctly import password next time, can't steal debt in the ATM.
