EAC (Extended Access Control)

Extended Access Control (EAC) is a security feature used in electronic identification documents like e-passports to protect sensitive data. It ensures that only authorized, trusted devices or officials can access personal information such as biometric data (fingerprints, facial images). EAC uses advanced encryption and authentication methods to verify the reader’s credentials before allowing access, preventing unauthorized parties from retrieving or tampering with the data. This enhances privacy, security, and trust in international travel and identification systems by safeguarding sensitive information from misuse or fraud.
