Abstract
The invention relates to a method and a system of identity authentication based on radio frequency identification and heart-sound technology. Safety problems exist in the prior authentication technology. The method provided in the invention comprises that at first an electronic code of each authenticated person and heart-sound waveform characteristics corresponding to the electronic code of each authenticated person are prestored; and that identity is authenticated by reading the electronic code of the authenticated person, comparing the prestored heart-sound waveform characteristics corresponding to the electronic code if the electronic code of the authenticated person exists in a storing device, and passing the authentication if the characteristics are matching otherwise failing the authentication. The system of the invention comprises devices including a radio frequency read-write device, a prestoring device and an authentication device. The method and the system realize double identity authentication through both radio frequency identity authentication and heart-sound identity authentication, which ensures accuracy and security of the identity authentication.
