  • Publication number: 20240160710
    Abstract: A reporting system determines whether an earphone is worn in one ear of a user, reports instruction information instructing the user to wear the earphone when it is determined that the earphone is not worn, and authenticates the user by otoacoustic authentication when it is determined that the earphone is worn in one ear after the instruction information is reported. The otoacoustic authentication is an authentication method that sends out a test sound in the direction of the ear canal of the one ear or other ear of the user, and authenticates the user based on the reflected sound to the test sound.
