Abstract
A safety bank card with double burglar - proof ciphers is featured as necessarily using current dynamic cipher after fixed cipher is used, forming dynamic cipher by cipher being arranged in sequence and being used only once, applying dynamic cipher at the first position as current dynamic cipher, deleting it by bank after it is used to finish one service and using cipher at next position as current dynamic cipher.
Description
The present invention a kind ofly has fixingly, and dynamically the safe bank card of double anti-theft cipher belongs to financial field electronic exchange instrument class.
Present bank card adopts a fixing password, exists when using bank card, and password can be stolen by the bad person, causes card to go up the stolen defective of fund.
The purpose of this invention is to provide a kind of safe bank card that prevents that password is stolen, can thoroughly eliminate the holder and when using bank card, cause the trouble and worry that fund is stolen on the card because of password is stolen.
The present invention is achieved in that the password of bank card is made up of fixed password and current dynamic password two parts, when bank card is opened an account, a fixed password at first is set, again the dynamic password of bank card is arranged to a plurality of use orders of having arranged in advance, each password is only limit disposable dynamic password, and the dynamic password that wherein makes number one is current dynamic password.The holder is when use is of the present invention, and the input fixed password after the bank computer system affirmation is errorless, can allow to enter next step operation: import the present dynamic password earlier.Bank computer system is reaffirmed errorless, can enter the practical business operation.After finishing this business, bank computer system is only limit this disposable current dynamic password to cancel at once and is deleted, and the next dynamic password of having arranged the use order is in advance started at once, changes to current dynamic password.Like this, the holder in all case can use bank card safely, even in use password is stolen by the bad person, it also is a useless sign indicating number that has cancelled that the bad person obtains with dynamic password, can not cause any harm to the holder at all.
The present invention has compared following beneficial effect with background technology: because dynamic password of the present invention can only disposablely use, be in the state of continuous variation, can guarantee that dynamic password can never be stolen in the bank card use, thoroughly stopped bank card in use causes economic loss because of password is stolen hidden danger, the present invention is compared with background technology has increased security, has obtained tangible beneficial effect.
Below in conjunction with embodiment the present invention is further specified: when someone founds bank card in bank, be provided with a fixed password 986 earlier, be provided with 6 dynamic passwords then again: 4921,5858,2980,6742,1535,3543, the dynamic password 4921 that makes number one promptly becomes current dynamic password.When the holder uses bank card, must import correct fixed password 986 earlier, after the bank computer system affirmation was errorless, current dynamic password 4921 was imported in next step operation of being allowed for access again, can enter the practical business operation.After finishing this business; the computer system of bank is cancelled the disposable current dynamic password 4921 of this limit at once and is deleted; and horse back starts next dynamic password: 5858; be set to current dynamic password to 5858; like this, even bank card has in use been got password by the bad person accidentally, but the dynamic password 4921 that the bad person obtains is a useless sign indicating number that has cancelled; can not be used for stealing the fund on the bank card at all, thereby bank card has been played effective protective effect.
