Abstract

A communication terminal device is provided with a communication unit; a memory unit that stores a telephone directory data having at least names, telephone numbers and display control information, a display unit that displays the information; and a control unit that carries out communication display prohibition control to prohibit the display unit from displaying a predetermined telephone number in the case where the display control information corresponding to such a predetermined telephone number is set to display prohibition when the communication unit communicates with a party with the telephone number. Thus, the communication terminal device cannot only keep secrecy more securely but also it can be a communication terminal device with which an easily useful telephone directory is provided.

Description

technical field [0001] The present invention relates to communication terminal devices such as mobile phones, and more particularly to a communication terminal device capable of effectively preventing leakage of personal information. Background technique [0002] Conventionally, in a mobile phone, the phonebook data with the name and phone number as the content is set by the user, and when an outgoing call or an incoming call is made, the outgoing call destination set in the phonebook data is displayed on the display device. land, the phone number of the caller. Also, when a name set in the phone book data is input, a phone number corresponding to the name is displayed on the display means. [0003] As a mobile phone equipped with such phonebook data, it has conventionally been proposed that a password can be set for each phonebook data to enable confidential management of the phonebook data (see Patent Document 1, for example). [0004] Patent Document 1: Japanese Patent ...
