摘要： Disclosed are an authentication apparatus using human body communication capable of improving the security and convenience of user authentication by using human body communication, a portable device having authentication function using human body communication, and an authentication method using human body communication. In the authentication method using human body communication, an authentication device acquires user biometric information and provides the acquired biometric information to a portable device by using human body communication. The portable device then compares the acquired biometric information with previously stored biometric information, and when the acquired biometric information and the previously stored biometric information are identical, the portable provides authentication information to the authentication device. Upon receiving the authentication information, the authentication device performs an authentication procedure based on the authentication information. Thus, security and user convenience can be improved, and an authentication can be quickly performed.
