PASSWORD VERIFYING DEVICE AND METHOD

摘要

A password verifying method includes 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.
