Risk identification method and device based on privacy protection

One or more embodiments of the invention disclose a risk identification method and device based on privacy protection, and aims to solve the problems of poor risk prevention and control effect and relatively large limitation of existing methods for performing risk prevention and control by using terminal edge computing power. The method comprises the steps of obtaining first text data generated inthe running process of a target applet; and performing semantic recognition on the first text data by utilizing a semantic representation model pre-deployed at the client to obtain a semantic representation vector corresponding to the first text data, wherein the semantic representation model is obtained by training based on a preset corpus and processing the semantic representation model by using a preset knowledge distillation method, the preset corpus comprises a first type of sample corpus with risk content and a second type of sample corpus without risk content. performing risk identification on the first text d
