With the advent of the multimedia era and the age of picture-reading, the recognition effect of sensitive content of image data has become the key to maintain the information security of network communities. At present, the image classification and recognition technology for sensitive images in network communities cannot obtain the semantic content of images, and it is difficult to combine the image information with the knowledge in network communities, resulting in low recognition accuracy and poor interpretability, and it is difficult to trace the transmission and fermentation of image information in network communities. To solve this problem, this paper proposes a sensitive image information recognition model of network community based on content text by using image caption technology. Through the text description of the image content of the network community, and the integration of a large number of network community text knowledge, the model can finally identify the images containing sensitive content more accurately and more understandable, and the transmission of image information on the network can be traced through the content text. In this paper, MSCOCO(Microsoft Common Objects in Context) dataset and sensitive image self-made dataset of network community are used as the training set. The experimental results show that the method presented in this paper is significantly better than the model based on image classification task in terms of accuracy and traceability of image sensitive information recognition results, which proves the feasibility and effectiveness of sensitive image information recognition in network communities based on content text.
