Document Type and Number:
Japanese Patent JP3480658
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an individual certification system using a password which is easy to be memorized by the person himself, which is difficult to be stolen by others, and which is easy to be confirmed after being inputted.
SOLUTION: A musical interval is assigned at random to each key constituting a key group 3 of a keyboard 1. A user decides a password corresponding to a desired melody, and memorizes the password corresponding to the melody. When the user inputs the password, the corresponding melody is outputted from a speaker 11. The user can judge whether or not the key input is correct by listening to the melody. Plural keys to which the same musical interval is assigned are present in the key group 3 so that the others can not steal the password by listening to only the melody.
