<p>The present invention relates to an apparatus for inputting a password and a method of inputting and decrypting a password. An original password (40) is composed of a password frame (42), an operator frame (44) and a shadow frame (46). The password frame is composed of four or more password numerals, and the shadow frame is composed of a number of numerals, which is identical to the number of numerals of the password frame. On a display unit, 10 numbers are randomly written at 10 addresses and displayed. An SPU (30) can recognize that the first numeral of a virtual password is generated by performing an operation on a number at an address corresponding to the first numeral of the password frame and the first numeral of the shadow frame through an operator, and the remaining numerals of the virtual password are generated through the above operation.</p> |
