Combining with hiding operation, method and the system in order to guarantee the interface access which minds visual arrangement pattern, improve the security of the computer system and the special-purpose terminal. Hint indication is drawn up at least as one which can be arrangement of numerical value quasi- random number. It is selected from hint indication, the user input which shows the pattern selection of the element which is connected inside algorithm one or mathematics above that, comparison and/or making use of logical operation is received. It is used in order to draw up the token from the hint indication which user input is compared in order to verify whether established pattern and algorithm, the user have known that pattern and algorithm. While offering hint such as color, dividing hint indication arrangement into sub arrangement, furthermore you use by showing each sub arrangement in the user, easiness can be offered.
