As successful Data Scientist, what can I do and what cannot to be GDPR compliant? Amazon Web Services (AWS) vs on-premise. De-identification vs Anonymization. Anonymization: removing, masking or suppression, generalization, k-anonymization, scrambling, blurring. Pseudonymization: tokenization, hashing, encryption, key deletion or crypto-shredding.
