A method for detecting the multi-data stream fusion of the distributed convolution neural network based on the Cuckoo search and the space interval sampling is proposed. It comprises of carrying out browsing information characteristic detection of a network user according to the multi-data stream fusion anomaly detection feature,establishing a feature extraction model of a multi-data stream fusion,and constructing a multi-data stream fusion quantitative characteristic analysis model reflecting the network security level. The method comprises of carrying out multi-data stream non-linear feature recombination by using a space under sampling technology,extracting the statistic feature quantity of the multi-data stream fusion anomaly detection,and realizing characteristic detection and identification according to the multi-data stream fusion abnormal distribution state. The self-adaptive optimization in the multi-data stream fusion anomaly detection is carried out in combination with a bird’s search algorithm. The simulation results show that the method has the advantage of high accuracy,high detection probability and strong anti-interference ability,and improves the security of the network.
