Introducing Privacy Receipts into DLT and eIDAS

I have published a research paper "Introducing Privacy Receipts into DLT and eIDAS" in the Journal of ICT Standardization. In short, there is a standards gap how digital identification (e.g., eIDAS2) and wallets standards (e.g., digital wallets, Solid Pods, and Personal Data Spaces) implement privacy principles (e.g., GDPR, ISO/IEC 29100). The individual has no real insights how their personal information is processed when sharing them from their digital wallet. This lack of insights is the motivation for the need of privacy receipts (e.g., Consent, ISO/IEC 27560).
