A multimedia data identification method and device, wherein the method comprises: inputting multimedia data to be identified into a pre-constructed neural network structure; wherein, the neural network structure comprises an adaptive leakage-integration-emission ALIF timing model, and the ALIF timing model comprises a multi-layer ALIF network layer; the multimedia data to be identified comprises image data and/or video data (S301); identifying and calculating the multimedia data to be identified through the multi-layer ALIF network layer in the neural network structure, and outputting a calculation result (S302). A novel algorithm ALIF that integrates SNN with ANN is proposed, can show better identification capability and anti-noise capability in fuzzy image identification tasks, the model is more robust and can effectively identify whether a target object is contained in the scene.
