Abstract

To protect an elderly person living alone or the like from a crime such as “a confidence game”, a personality feature indicative of personality is extracted from a voice signal of a person required to be preliminarily registered and stored into a storage. When a call is received, a personality feature indicative of personality is extracted from a voice signal from a telephone line and compared with the personality feature stored in the storage to determine whether or not the caller of the voice signal input from the telephone line is any of persons whose personal features are registered in the storage, and notifies of the result of determination. Consequently, when there is a call from an unregistered person whose personal feature is not stored in the storage, the fact is notified.
