Then, the screen shifts to the partner setting screen 81 shown in FIG. The destination setting screen 81 displays a list of destinations for setting ringtones. In this example, the destination is set in units of groups, but may be set for each individual. When setting is made by selecting a partner from the partner setting screen 81, a melody registration end notification screen 82 shown in FIG. 13C is displayed. Here, the file name is set by the mobile phone 1, but the user may arbitrarily set the file name.
[0068]
As described above, according to the mobile phone 1, when the entry to the encrypted mail menu is instructed, the CPU 2a allows the user to input the personal identification number, and when the personal identification number matches, the CPU 2a can create the encrypted mail. To do. Then, when transmitting the created encrypted mail, the CPU 2a refers to the set encryption table file, converts the hiragana to the corresponding note data based on the encryption table file, and generates note message data. The data is transmitted via the transmission / reception unit 8.
[0069]
When there is an instruction to display the text of the received mail, the CPU 2a displays the mail with a note mark representing “sound length” of the note data as a display indicating the received note data, so the encrypted mail is encrypted. Displayed with note marks. When the display of the message processing menu is instructed, the CPU 2a causes the user to input the personal identification number, and displays the message processing menu screen when the personal identification number matches (correct). When decryption is selected from the message processing menu screen, the CPU 2a refers to the encryption table file set at the transmission source address and displays the message on the display unit 7 in the hiragana corresponding to the note data. When reproduction is instructed, the CPU 2a writes the received note data to the expansion buffer in the CPU 2a, and the melody reproduction unit 15 reproduces the melody based on the expanded data. When the melody registration is selected, the CPU 2a saves the received note data in the storage unit 5 as a melody file with a file name. When the ring tone setting is selected, the CPU 2a sets the melody of the received note data as a ring tone based on the setting information, and stores the note data in the storage unit 5 as a melody file. When the deletion is instructed, the CPU 2a deletes the received message stored in the storage unit 5.
[0070]
In addition, when there is an instruction to confirm the text of the created mail or sent mail, the CPU 2a displays the mail by encryption using musical note data with reference to the set encryption table file. When decryption is instructed, the CPU 2a causes the user to input a personal identification number, and when the personal identification number matches (correct), displays a message in hiragana corresponding to the note data.
[0071]
Therefore, the encrypted mail is a complex note data in which the data to be transmitted is composed of “scale”, “octave”, “tone length”, “tone”, and the same encryption table is used by both the sender and the receiver. If it is not converted, the correct decryption cannot be performed, so that the security at the time of mail transmission can be enhanced. Also, if the entered security code is not correct, the decryption display of the mail being created, the sent mail, and the received mail cannot be performed. Therefore, it is necessary for another person to operate the mobile phone 1 and confirm the contents of the mail. Can prevent and protect privacy. Further, since the message melody can be transmitted to the other party without attaching the melody file, the message and the melody can be transmitted / received simultaneously while suppressing the amount of information. Furthermore, since the received note data can be reproduced, registered as a melody, or set as a ringtone, the user can use the encrypted mail more happily.
[0072]
