Why would you need "to anonymize vast amounts of data — so that it’s no longer tied to customer information" or "appl[y] access policies" if the data contain no PII? Presumably the ML is anonymizing the data and the access policies are necessary because the data contain PII.
- thruflo 7y agoYup, people tend to confuse concepts and refer to synthetic data as anonymised data. They are very different things. Anonymised data or redacted data are transformations of a data set that _hopes_ not to leak too much PII / sensitive data. People don’t use ML to anonymise but they do use ML to classify as a first step before splatting or generalising. In that case, its absolutely right that the ML classifier not being 100% results in PII leaking. This is a key reason why anonymisation and redaction are widely seen as problematic and are being replaced by synthetic data and, maybe in future, homomorphic encryption.
