<p>PROBLEM TO BE SOLVED: To access secret data by the use of a password which is easily memorized by a specific user and can not be understood by other persons. SOLUTION: When a password consisting of the combination of optional pictograph data and its color specification data is inputted by selectively depressing a secret key 12g, a pictograph key 12b, color keys (red, blue and green) 12d, or the like on a key input part 12 and stored in a password edition memory 15 and a 'registration' key 12e is depressed, the password is stored and registered in a password storing memory 16. When the password is inputted by similar password input processing and a 'collation' key 12f is depressed, the registered password data are compared with the inputted collating password data, and when both the data coincide with each other, an access to secret data stored in a secret data memory 17d included in a RAM 17 can be permitted.</p> |
