User identification method and device, storage medium and terminal equipment

The invention discloses a user identification method and apparatus, a storage medium and a terminal device. The method comprises the steps of collecting a user data stream of a to-be-identified user according to a preset identification duration; the user data flow is preprocessed according to a preset time interval, distribution characteristics and statistical characteristics are obtained, the distribution characteristics comprise flow duration distribution, message length distribution, message arrival time distribution and byte number distribution, and the statistical characteristics comprise an average time interval and the message length with the maximum probability; inputting the distribution features and the statistical features into a trained fingerprint feature model to obtain a user fingerprint of the to-be-identified user; and querying a preset fingerprint feature library according to the user fingerprint to obtain an identification result of the to-be-identified user. By adopting the technical schem
