A new auditing framework evaluates label-privacy leakage in ML models without modifying training data. By testing how well an attacker distinguishes between training labels and proxy labels, researchers showed that stronger privacy settings greatly reduce leakage signals.
Consistent results across datasets suggest this could lower the operational barriers to ML privacy testing.

What’s your view - is this a step forward for practical ML security?
