Definition: e-Seal Preservation ABB is an Application Service that enables the procedures to extend the trustworthiness of the qualified electronic signature beyond the technological validity period. Source: eIDAS - REGULATION (EU) No 910/2014 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC. Source reference: http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv%3AOJ.L_.2014.257.01.0073.01.ENG Additional information: An ‘electronic seal' means data in electronic form, which is attached to or logically associated with other data in electronic form to ensure the latter’s origin and integrity. The ‘creator of a seal’ is a legal person who creates an electronic seal. Example: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): CEF eSignature DSS - DSS (Digital Signature Services) is an open-source software library for electronic signature creation and validation. DSS supports the creation and verification of interoperable and secure electronic signatures in line with European legislation. In particular, DSS aims to follow the eIDAS Regulation and related standards closely. DSS can be re-used in an IT solution for electronic signatures to ensure that signatures are created and verified in line with European legislation and standards. DSS allows re-use in a variety of different ways: in an applet, in a stand-alone application or in a server application. DSS can also be used as a reference implementation for IT solutions which do not directly re-use it. CEF eSignature's DSS open-source library delivers the following benefits to its users: • Open-source software under LGPL 2.1, a non-viral open source license; • Interoperability of the e-signatures; • Supports both e-signatures and e-seals; • Validation of countersignatures and multiple signatures; • Alignment with the eIDAS Regulation and related standards; • Supports EU standards on: o Signature formats and packaging methods; o Signature validation procedures; • Validation relying on Member States' trusted lists: o Status of trust service providers/trust service, compensation of information, path validation. https://ec.europa.eu/cefdigital/wiki/display/CEFDIGITAL/eSignaturefile:///C:/Users/bocquilp/Downloads/DSS(ServiceOfferingDescription)%20(v0.03)%20(5).pdf eira:iopDimension: Behavioral IoP LOST view: TVA-Trust Enablers [Motivation] Viewpoint: Interoperability Security viewpoint eira:iopSaliency: The e-Seal Preservation Service ABB  is salient for technical interoperability because it provides the functionalities required for e-seal preservation service.
