Outline

This paper addresses the issue that street-level image data released as open data plays a crucial role in the advancement of autonomous driving systems and AI research, but poses significant privacy risks due to personally identifiable information (PII). In particular, the existence of PII beyond biometric information such as faces is a concern. In this paper, we present cRID, a novel cross-modal framework that combines large-scale vision-language models, graph attention networks, and representation learning. cRID focuses on identifying and leveraging interpretable features to detect semantically meaningful PII beyond low-level appearance cues. Experimental results demonstrate improved performance, especially on a practical cross-dataset Re-ID scenario from Market-1501 to CUHK03-np (Detected), highlighting the practicality of the framework. The code is available at https://github.com/RAufschlaeger/cRID .

Takeaways, Limitations

Takeaways:
We present a novel method to improve PII detection performance by combining large-scale vision-language models and graph attention networks.
Ability to detect semantically meaningful PII beyond low-level appearance cues.
We demonstrate performance improvements in a practical cross-dataset person Re-ID scenario.
Achieving transparency in PII detection by leveraging interpretable features.
Limitations:
Limited to performance evaluation on specific datasets, further research is needed on generalizability.
Lack of comparative analysis of detection performance for different types of PII.
Lack of applicability and performance evaluation in real autonomous driving environments.
