The Leak Lived in the Pipeline, Not the Language Label
English leaked most under one filter, while Arabic and Swahili retained residuals after an added input judge.
Summary
English leaked most under one filter, while Arabic and Swahili retained residuals after an added input judge.
A five-language audit of one Qwen-based RAG pipeline found English had the highest unstructured synthetic-PII leak rate with output filtering alone. Adding an input judge left residual leaks in Arabic and Swahili; the authors explicitly frame the result as pipeline-conditional and do not measure benign-query false positives or utility cost.
Why it matters
English leaked most under one filter, while Arabic and Swahili retained residuals after an added input judge.
Limits and context
- Adding an input judge left residual leaks in Arabic and Swahili; the authors explicitly frame the result as pipeline-conditional and do not measure benign-query false positives or utility cost.
