Windows Copilot provided incorrect information regarding HIPAA regulations on data de-identification, specifically concerning the use of secret keys for pseudonymization. The AI confidently asserted that sharing a key for hash-based pseudonymization would de-identify data, while keeping it secret would not. However, the actual regulation, 45 CFR 164.514, states that data derived from an individual's information is not de-identified if it can be translated back, and that disclosing the re-identification mechanism is prohibited. The AI's explanation was flawed on both counts, potentially leading users to incorrectly believe their data was de-identified when it was not. AI
