Embodiment 1

[0048] In order to verify the effectiveness of the present invention, different types of pictures crawled from the Internet by crawler programs are used to divide sensitive categories into four categories, including sensitive category A, sensitive category B, sensitive category C and other categories. Sensitive text datasets are obtained by splicing and reorganizing related sensitive words, including sensitive category A, sensitive category B, sensitive category C and other categories. The normal text data set comes from the normal comment set of Weibo. Technical scheme of the present invention can be specifically implemented as follows:

[0049] (1) In the sensitive model training stage. Use the sensitive word library of jieba word segmentation to train the text model; in the process of image model training, firstly, the input image is randomly flipped, sheared, enlarged, cropped, etc. to expand the data set to increase the diversity of the image, and finally the The images...

Abstract

A multi-modal fusion sensitive information classification detection method comprises the steps of 1, carrying out sensitivity primary detection on a text and a picture, 2, judging the sensitivity of the text based on emotion, and 3, carrying out multi-modal sensitivity detection of image-text fusion, and the sensitive information is detected and classified by combining two modes of the text and the picture. Sensitivity detection needs to be carried out on the text and the picture respectively, and the sensitivity of the content can be accurately judged in combination with the influence of emotion polarity and intensity on sensitive information. The image-text sensitivity problem is solved according to a proper fusion method, and high detection precision is achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a multi-modal fusion sensitive information classification and detection method. Background technique [0002] With a large number of Internet users around the world, online social networks have become the preferred platform for information exchange. With the popularization and application of social networks more and more widely, the information of social networks takes pictures, texts, audio and video as the carrier, showing a trend of diversification, complexity, and massification. A large amount of sensitive information is flooded in social networks, seriously affecting Cybersecurity and people's physical and mental health. How to use artificial intelligence technology to efficiently and accurately detect sensitive information has become an urgent problem to be solved in academia and industry. [0003] Most of the existing research on sensitive information detection uses...
