A database leaked. Thousands of names, emails, and IDs exposed. The breach was fast, silent, and total. Under GDPR, the clock starts ticking the moment it’s discovered.
GDPR identity rules define how personal data must be stored, accessed, and deleted. Identity under GDPR is not just a username—it includes any information that can directly or indirectly identify a person. That means names, addresses, IPs, device IDs, even cookie identifiers. Mishandle any of it, and you risk fines up to 4% of global revenue.
The regulation demands strict identity management. You need consent before storing personal identifiers. You must encrypt data at rest and in transit. You have to minimize what you keep—collect only what you need and nothing more. And when a subject requests erasure, deletion must be complete, including backups if possible.
For developers, GDPR identity compliance starts in the code. Map every flow of data that contains identifiers. Ensure role-based access controls guard that data. Monitor access logs for anomalies. Apply pseudonymization to reduce risk if a breach occurs. Document every decision. Auditors will want proof.
