The embodiment of the invention provides a privacy leakage detection method based on a parallel deep neural network. In the embodiment of the invention, firstly, sensitive privacy features are extracted from each piece of privacy sample data of an obtained privacy
data set to obtain sensitive privacy feature vectors corresponding to the privacy sample data; afterwards, N CPU cores on the device parallelly
train a corresponding DNN model based on the sensitive privacy feature vectors corresponding to the privacy sample data, so that when any detection device needs to detect any target network flow, the trained DNN model is utilized to detect whether privacy leakage occurs in the target network flow or not; therefore, detection of privacy leakage of
the Internet of Things equipment is realized, and
information security of
the Internet of Things equipment is ensured. In the embodiment of the invention, the N CPU cores are used for training the plurality of DNN models in parallel, so that the
model parameters among the DNN models do not influence each other, the
coupling among the DNN models is avoided, and the performance of each DNN model is improved.
