Abstract

This invention relates a secret data storage device capable of setting password data which is easy for a specific user to memorize but is difficult for others to understand. A registration password data item composed of an arbitrary hieroglyphic data item or a combination of an arbitrary hieroglyphic data item and the color specifying data corresponding to the hieroglyphic is entered by selectively operating the hieroglyphic key 12b and color key 12d in the key input section 12. Similarly, using the color specifying data item and the like, a collation password data item is inputted. Then, it is determined whether or not the registration password data item coincides with the collation password data item entered this time. When it has been determined that they coincide with each other, the secret data stored in the secret data memory 17d is accessed and the accessed data appears on the display section 19.
