The embodiments of the invention provide a bill identification method and apparatus. In one embodiment, the bill identification method includes the steps of inputting interference bills generated by acounterfeiting network and prestored real bills into a counterfeit identification network to be trained to obtain output data; inputting the output data to a judgment network to perform classification of the interference bills and real bills, so as to obtain a corresponding counterfeit identification network model when the interference bills and real bills are divided into different categories; and inputting a bill to be detected to the counterfeit identification network models to be identified, so as to obtain an identification result of the bill to be detected.
