A regulator warns of increased risk of AI re-identification attacks on anonymized datasets.

AAISM states that anonymization is not permanent and may be reversible through re-identification attacks. The first action should be to evaluate and measure the actual privacy risk through:

• adversarial re-identification testing

• privacy audits

• monitoring for misuse

This provides the factual basis needed before making destructive or operational decisions.

Access control (D) is important but not the FIRST step. Deleting datasets (B) is premature. Assuming anonymization is permanent (A) violates AI privacy principles.
