Step S207, dynamic token obtains transaction content according to light signal.
For example, behind the black-white colors figure that occurs on the transaction terminal flashing, with the phototriode position alignment image of dynamic token, this moment, triode will collect the variation of color, according to the different electric current of difference output of color, for example the electric current of white can be larger, and the electric current of black can be less.The electric current of different sizes can be exported the high low-voltage that varies in size by resistance.Again high low-voltage is converted into high-low level, just can have received the data message of transaction terminal.
Step S208, dynamic token generates the second dynamic password according to transaction content.
S205 is similar with step, is not described in detail herein.
Step S209, user judge whether transaction content is correct.
After dynamic token gets access to transaction content, can show at display screen.Thus, the user judges whether transaction content is correct.
Step S210, if transaction content is correct, then the user inputs to transaction terminal with the second dynamic password.
If transaction content is incorrect, abort operation then.Thus, reduced the risk that customer transaction is tampered.
Step S211, transaction terminal is sent to remote server with the second dynamic password.
Step S212, whether remote server verification the first dynamic password and the second dynamic password mate.
Step S213 is if the first dynamic password and the second dynamic password coupling are then determined to conclude the business.
If the first dynamic password and the second dynamic password do not mate, then abort operation.
The execution that it should be understood that some step among this method embodiment there is no obvious sequencing, for example can first execution in step S204, again execution in step S202.Ability generated the first dynamic password according to user's transaction content when more for example, remote server needed to carry out password authentication after receiving the second dynamic password.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment that scope of the present utility model is by claims and be equal to and limit.
