Present embodiment also provides a kind of dynamic password formation method on the other hand, and as shown in Figure 5, the method comprises:
Step S201 receives the challenge code of inputting.
Concrete, the challenge code that receives the manual input of user or obtain by wire/wireless communication.
Step S202 judges whether challenge code is correct.
Concrete, check that such as the user challenge code input is errorless, then carry out step 203; Such as the incorrect step S201 that then skips to.
Step S203, judge challenge code correct after, the confirmation of receipt instruction.
Concrete, the user confirms its correctness by button after confirming that challenge code is correct.
Step S204 is according to confirming instruction execution in step S205.
Step S205 resolves the challenge code that receives, and obtains discernible Transaction Information.
Concrete, utilize the analytical algorithm that is complementary with the challenge code generating algorithm that prestores that challenge code is resolved, obtain discernible Transaction Information.Transaction Information comprises the key messages such as transaction account and dealing money at least, so that the user checks account number and the amount of money, prevents dynamic password by improper use, causes the dangerous of user's fund.
Step S206, the output display Transaction Information.
Step S207 compares the Transaction Information that obtains and the described account information of storage, if compare inconsistent, output display identification information then.
Concrete, at least one account information in the E-token dynamic password card in order to preserve reliable Accounts List in E-token dynamic password card, is compared after getting access to account.
Step S208 judges whether Transaction Information is correct;
Concrete, the user checks the Transaction Information (for example: transaction account and dealing money) of demonstration, determines whether correctly, as correctly then continuing step S209; As incorrect, terminating operation then.
Step S209, judge Transaction Information correct after, the confirmation of receipt instruction.
