Just one example is the workflow/policy area of student mobility. Others are from public administration and from economic sectors. According to the eIDAS regulation, eID and trust services (TS) are available across EU - upcoming also EUid & wallets (eIDAS 2.0) - to improve security aspects (providing interoperability or standards). We present some security enhancements to maintainhigher trustworthiness in Identity and Access Management (IAM) services for different policy areas with mandatory, owner-based and self-sovereign control aspects - based on eIDAS and different standards and the integration of views/results from deployed or ongoing projects (EMREX/ELMO, Europass/ EDCI, eIDAS, EUid, Verifiable Credentials, NBP initiative, OZG implementation, Self-Sovereign Identities SSI, RBAC, ABAC, DAC/MAC, IPv6) and a trustistor.eneIDAS eID & TS (2.0)EUidIAMLoAauthenticationaccess controlnotarisationNBP initiativeOZGSelf-Sovereign Identities SSIRBACABACDAC/MACIPv6Text/Conference Paper10.18420/OID2022_111617-5468
