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.

Abstract: The present application discloses a method and device for transmitting and receiving instruction information. The method for transmitting instruction information includes: acquiring a first audio signal that is output from an audio interface of a mobile terminal and carries first instruction information and/or second instruction information, wherein the first instruction information is used to instruct a receiving device to perform an operation corresponding to the first instruction information, and the second instruction information is used to instruct to send the first instruction information to the receiving device; and generating, according to the acquired first audio signal, a first transmission signal that carries the first instruction information, and sending the first transmission signal to the receiving device, where the first transmission signal is a light signal or a sound wave signal.

Abstract: The present invention provides an identity authentication system, apparatus and method and an identity authentication request apparatus. The system includes: an identity authentication request apparatus, configured to send a verification code issuing request to an identity authentication apparatus; the identity authentication apparatus, configured to respond to the verification code issuing request sent by the identity authentication request apparatus, generate an ID and a corresponding verification code according to the verification code issuing request, bind the generated ID and the verification code, store the generated ID, the verification code, and a binding record, and feed back feedback information that carries the verification code to the identity authentication request apparatus. The present invention provides a practical and effective identity authentication mechanism.

Abstract: The present disclosure discloses a photon data transmission method and device for a mobile terminal, where to-be-transmitted data is encoded by tuning a light luminance intensity combination so as to send more information and improve security. Preferably, before encoding, luminance of a flash is controlled and data of a specific information amount is sent, and a photonic receive end recognizes a light signal, and according to a recognition result, determines a maximum quantity of luminance levels of signals supported by the photonic receive end, and then performs encoding according to a recognition capability of the photonic receive end. In this way, it is ensured that the photonic receive end can recognize the signals, and that sent code can make full use of luminance of a flash of a mobile phone.
