英文摘要User-Generated Content (UGC) on social media has created a wealth of geographic information. However, it also presents a significant geoprivacy challenge. Image geolocation is the task of identifying an image's location. It offers benefits in domains such as disaster response and autonomous driving. Concurrently, it enables the inference of personal locations from implicit geographic cues within the images. Thus, quantitatively assessing the implicit geoprivacy risk of images is becoming increasingly important. To address this problem, this study constructs a Bayesian Network that includes (1) a comprehensive feature set of 11 metrics in four categories of an image's geolocation, (2) a taxonomy of five core geolocation methods, modeling the causal pathways from the features to the methods, and finally to the vulnerability. We constructed a dataset with 42,576 real-world examples of image geolocation. The model's AUC reaches 0.90 on the test dataset (where 1.0 is perfect and 0.5 is random chance). The results also support that task attractiveness, scene complexity, and landmark level are vital factors in determining the final localization probability. This study provides granular insights into how specific features influence the choice of localization pathways.
