  • Personal Information: Name, date of birth, nationality, address. 
  • Identification Documents: Passport, identity card, driver’s license. 
  • Educational Credentials: Diplomas, certificates, degrees. 
  • Financial Information: Bank details, transaction history. 
  • Travel Credentials: Visas, airline tickets, residence permits. 
  • Health Data: European Health Insurance Card, medical prescriptions. 

Technologies and Protocols Used 

For the implementation of attributes in the Digital Identity Wallet, the EU uses a combination of advanced technologies and security protocols to ensure data protection and interoperability among member states. The main technologies and protocols used include: 


Blockchain technology is used to ensure the integrity and security of data transactions. Whenever an attribute is verified or updated, the transaction is recorded on an immutable blockchain, making data tampering extremely difficult. 

Asymmetric Cryptography 

Asymmetric cryptography is used to protect data during transmission. By using public and private keys, only authorized recipients can decrypt the information, ensuring that sensitive data cannot be intercepted by unauthorized third parties. 

eIDAS (Electronic Identification, Authentication and Trust Services) 

The eIDAS Regulation provides a standard for electronic identification and trust services, ensuring that digital identities are recognized and accepted across all EU member states. eIDAS defines the assurance levels for authentication and electronic signatures, ensuring that digital identities are secure and reliable. 

SSI (Self-Sovereign Identity) 

The Self-Sovereign Identity (SSI) model allows users to have full control over their personal data. Users can choose which attributes to share and with whom, reducing the risk of unnecessary exposure of personal information. 

 Interoperability Protocols 

Interoperability protocols such as OAuth 2.0 and OpenID Connect enable the Digital Identity Wallet to interact with various services and platforms. These standardized protocols facilitate the integration of the wallet with third-party applications, ensuring a smooth user experience. 

Mobile Device Management (MDM) 

Mobile Device Management (MDM) solutions are used to ensure that the Digital Identity Wallet is secure even on mobile devices. MDM allows for access management, the application of security policies, and monitoring the integrity of data on users‘ devices. 

Importance for the Professional Sector and Businesses 

The implementation of the EU Digital Identity Wallet and its attributes is crucial for the professional sector and businesses. This tool represents a significant breakthrough in terms of efficiency, security, and transparency in daily operations.
