The invention relates to a handwriting identification and user authentication system, in particular to a signature identification system and an authentication method based on combination of dynamic handwriting detection and user identity identification and authentication of an RFID single tag. The system comprises a signal acquisition device based on an RFID tag, an antenna and a plastic container, a signal induction device based on a reader and a background device based on a computer; the signal induction device and the background device are connected through a network cable, and the tag and the antenna are oppositely arranged in the plastic container to form a closed signal acquisition space. The dynamic time warping technology and the neural network technology are introduced for similarity calculation and signature recognition matching, a real-time signature handwriting detection system is compiled, the system achieves effective recognition of the signature of the person by checking space and time informat
