Age Verification in the Context of the EUDI Wallet: Balancing Privacy and Security

Abstract

As digital identity solutions become increasingly prevalent, the necessity for robust age verification mechanisms has emerged as a critical concern for a range of services, from online transactions to access to age-restricted content. Current age verification methods often fall short of accommodating the diverse standards across jurisdictions, leading to vulnerabilities and inconsistencies in user experience. One of the main objectives of this study is to identify and analyze in a systematic way existing age verification methods and the main relevant international regulatory frameworks. The Age Verification Profile by the European Commission is including and exploring Zero-Knowledge Proof-based solutions for age verification, which are also considered in the EUDI Wallet Architecture and Reference Framework. This approach not only minimizes data privacy risks but also facilitates seamless digital interactions across the European Union. This paper primarily aims to explore the critical role of the European Digital Identity Wallet Architecture and Reference Framework in age verification and demonstrate that the EUDI Wallet seeks to enhance the security and efficiency of online transactions by introducing robust age verification mechanisms that effectively balance user privacy, security, and compliance with various regulatory requirements while preventing unauthorized access to services with age restrictions, which is in line with the broader objectives of the European Digital Identity initiative. Furthermore, we examine the European Union's age verification approach via the EUDI Wallet and the U.S. framework approach, conducting a comparative analysis between them that highlights key differences in architectural design and legal underpinnings and emphasizes their advantages.
