Privacy & Security

How your data and payments would be protected.

Privacy is one of the most debated aspects of the digital euro. The ECB has repeatedly stated that the digital euro would offer the highest privacy standards of any digital payment option — but what does that actually mean?

The ECB's Privacy Commitment

The ECB and Eurosystem have committed to a core privacy principle: they would not be able to identify who you are or what you're buying from the payment data they receive. This is a fundamental distinction from commercial payment platforms, which typically have full visibility of transactions.

Online vs Offline Privacy

Privacy protections differ depending on the payment type:

Offline payments: Designed to offer cash-level privacy. Like physical cash, offline digital euro payments would not be visible to the ECB, intermediaries, or third parties. These transactions would be processed locally on the devices of the payer and payee.
Online payments: Subject to anti-money laundering (AML) and counter-terrorism financing (CTF) regulations. Intermediaries would perform necessary checks, but the ECB would still not see individual transaction details. Supervisory authorities would only access data under strict legal conditions.

What the ECB Can and Cannot See

✓ Cannot see	Who you are, what you're buying, who you're paying
✓ Cannot see	Individual transaction amounts or patterns
✓ Cannot see	Your account balance
○ Aggregated data	May access anonymised, aggregate statistics for monetary policy

Supervisory Access

Under EU law, financial authorities can access certain data for AML/CFT purposes. The digital euro framework includes:

Strict legal thresholds: Data access only permitted above certain transaction thresholds.
Judicial oversight: Access requires legal authorisation, not arbitrary surveillance.
Data minimisation: Only necessary data is processed and retained.
GDPR compliance: Full alignment with EU data protection regulations.

Security Measures

The digital euro would incorporate multiple layers of security:

Central bank backing: No risk of issuer default — the ECB stands behind every digital euro.
Cryptographic protection: Advanced encryption secures all transactions and communications.
Secure hardware: Offline payments use tamper-resistant secure elements on devices.
Two-tier oversight: Both the ECB and supervised intermediaries monitor for fraud.
EU cyber standards: All infrastructure must comply with EU cybersecurity regulations.

Addressing Public Concerns

The ECB acknowledges public concerns about surveillance. Key mitigations include:

The ECB has no commercial incentive to monetise payment data (unlike private payment platforms).
Offline payments provide genuine cash-like anonymity for everyday transactions.
The legislative framework includes explicit privacy guarantees written into EU law.
Independent privacy oversight bodies would monitor compliance.

The digital euro would offer people and businesses in the euro area a payment solution with the highest privacy standards. — ECB
