A certification pattern storing method by the present invention includes: (1) a first step in which a server encodes an image including a random number table with a disposable key generated based on first information, and a user terminal receives the image transmitted after the encoding; (2) a second step in which the user terminal generates a disposal key based on the first information and decodes the encoded image; (3) a third step in which the user terminal receives an input of letters arranged by a predetermined pattern in the random number table; and (4) a fourth step in which the user terminal stores a pattern determined by the inputted letters in the server by transmitting the pattern to the server. |
