PASSWORD VERIFICATION DEVICE AND PASSWORD VERIFICATION METHOD

摘要

A password verifying device employing a password verifying method is disclosed. The method includes comprising the following steps: providing a plurality of interactive regions on each of which several known characters are arranged and shown randomly, at least one interactive region containing at least two characters; accepting selection of said plurality of interactive regions made by the user, and after selection of present interactive regions by the user, randomly re-distributing said several known characters into said respective interactive regions to be shown and selected for next time; and comparing one by one characters contained in a predefined password sequence with characters contained in the interactive regions selected each time, and outputting signal representing successful password verification when each character contained in the password sequence is identical to a corresponding character shown in a corresponding interactive region selected each time. By causing fuzziness to the contents input by the user, the input contents become multi-vocal, thus ensuring the password will not be given away during input process. In addition, by randomly generating dynamical effect of the contents input by the user, password operation complexity is increased. This comprehensively and entirely improves safety and convenience of the password verification process.
