The utility model provides a fingerprint dynamic password authenticating apparatus based on Bluetooth communication. The fingerprint dynamic password authenticating apparatus comprises a microprocessor, a Bluetooth communication unit, a fingerprint authenticating unit, and a dynamic password unit, wherein the Bluetooth communication unit, the fingerprint authenticating unit, and the dynamic password unit are connected with the microprocessor. The fingerprint authenticating unit is used for acquiring and authenticating the fingerprint information of a user, and transmitting an authenticated result of the fingerprint information to the microprocessor. According to the authenticated result of the fingerprint information, the microprocessor determines whether to transmit first information to the dynamic password unit. The dynamic password unit is used for generating and transmitting a dynamic password to the microprocessor according to first information. The microprocessor communicates with a terminal by using the Bluetooth communication unit, receives the first information transmitted from the terminal, and transmits the dynamic password to the terminal. The safety of the fingerprint dynamic password authenticating apparatus is improved by fingerprint authentication. Problems of equipment theft and low safety in the field of identity authentication are effectively solved. The fingerprint dynamic password authenticating apparatus has wide application prospect. The utility model also provides a fingerprint dynamic password authenticating system based on Bluetooth communication.
