In the case of door locks most widely used in the market, the most used area as a one-dimensional problem is worn out, and a worn area which does not use a special attack method enables password guessing. To solve this problem, various methods such as a keypad for randomly displaying numbers are introduced, but this is also not completely safe. The common feature of all the solutions so far is that the keypad area is fixed. In this paper, we consider that point in reverse and create a new area smaller than the entire area in the entire area of the keypad, making the keypad of the new area move randomly, thereby preventing the password from being deduced. When using this technique, a new type of keypad is proposed for the first time because of the impossibility of a shoulder surfing attack even though the number of keypad is left as it is.
