Abstract
The present application discloses an authentication system, and a transmit terminal, a receive terminal, and a right authentication method of same. The receiver externally propagates, by using the information transmit module, an identification code information set corresponding to the receiver. After receiving the identification code information set, the transmitter firstly performs a first right authentication on rights of the transmitter. The transmitter allows itself to transmit a light signal of an identification code of the transmitter only after the authentication is passed, thereby reducing a security risk caused by uncontrolled transmission of the light signal of the identification code of the transmitter by the transmitter. After the transmitter transmits the light signal of the identification code of the transmitter, the receiver performs a second right authentication on the received light signal. In this way, security of the authentication system is further improved.
