Introducing Privacy Receipts into DLT and eIDAS

The introduction of digital identification (e.g., eIDAS) and wallet standards (e.g., EUDI wallet) require compliance with privacy principles and clear communication of the principles through privacy notice and record of consent in the form of a privacy receipt. Regulation needs standards to help set the bar for reducing the privacy infringement risk. Without a standard-based implementation, solutions will be proprietary and siloed with no concern for interoperability, like privacy labels in Google and Apple app stores. Do existing standards address the gap, or do new ones need to be introduced? This article looks at the standards and regulations in three areas to answer this question: privacy protection standards, blockchain and DLT standards, and digital identification and wallet standards.
