The leakage of personal privacy data occurs frequently on the dark web. This paper has discovered the strong correlation between personal privacy data transactions on the dark web and telecommunication network fraud crimes. Therefore, obtaining the privacy data from the dark web will be of great significance to control telecommunication network fraud and crackdown on illegal private data transactions. This paper uses web crawlers to obtain information about personal privacy data transactions on the dark web. Then we analyze the correlation between the information and the judgment document data of the telecommunication network fraud cases published on China Judgments Online. It is shocking to find out that the two types of data have similar quantity distribution and the Spearman correlation coefficient between them is 0.782even though they are completely independent. Hence it can be inferred that the personal privacy data sold on the dark web is likely to be used by criminals to implement precise telecommunication network fraud. Research on the correlation between personal privacy data on the dark web and telecommunication network fraud cases on China Judgments Online has a certain warning effect on both individuals and enterprises.
