2. Objectives
Presentation of Lithuania’s road preparing for electronic documents. Special attention to development of Electronic Archive Information System (EAIS) that was the final step completing this preparation.

3. 2000: Law on Electronic Signature

4. 2006: “Tool-first” approach (e.g., Justa)
2007: e-Servicing (Declaration) System of the Insurers (EDAS)

5. 2008: Minimal requirements for the specifications
2009: ADOC specification
2010: MDOC specification

6. 2009: public free software tools
2009: e-Servicing System of the Citizens (EGAS)
2011: Electronic Declaration System of State Tax Inspectorate (EDS)
2011: the Government electronic signature information system (ELPAS)
2011: EAIS

7. Model of Electronic Document

8. Interoperability problem
The main standardizations efforts in the EU are still targeted to electronic signature formats.
Member states should be able to process (validate) the e-signatures formats: XAdES, CAdES, and PAdES.
The true artifact of interoperability is an electronic document.

9. Conventional official documents
Very complex entity:
Various content
Appendices and/or attached independent earlier created documents
Signed by one or more signatures
Registered and possesses corresponding attributes

10. Official electronic documents
Should be adequate to the conventional documents
Consist of three parts: - content, - signatures, - metadata.

11. Logical structure of el. document

12. Current el. document specifications

13. Product line Signa
Signa Desktop – public free Windows OS application (download from
Signa Web – public free web application (available at
Signa SDK – a set of application libraries for Java and .NET platforms (supports all current specifications)
Signa Docs – web application for enterprises (featuring multiple users, electronic document workflows and the ability to sign with qualified signatures multiple electronic documents in bulk; ELPAS is based on it)

14. Electronic Archive Information System

15. Project goal
To create an integral open IS for accepting and storing electronic documents of National Document Fund (NDF), providing a legal access to the stored documents using IT and communication means, administering NDF efficiently and providing electronic services.

16. EAIS important features
Deals with electronic documents that are original documents, having the same legal value as handwritten (handsigned) documents.
Assures the integrity, authenticity, non-repudiation and possibility to use the electronic documents for a long or unlimited time.
The system is unique (we do not know other corresponding system).

17. EAIS main parts Public portal Internal portal
Storage of electronic documents: - physically located in Vilnius and Šiauliai - data replication - accessible through internal portal only

18. EAIS subsystems

19. EAIS important functionality
Authentication of external users through e-government gateway
All public functions could be invoked interactively and through corresponding Web services
Flexible configuration of authenticity checks
Retention risk management: - converting content into long-term storage files (PDF/A format) - extending e-signatures to XAdES-A format - means for physical preservation of electronic documents

20. EAIS conclusions EAIS has been launched in October 2011.
The first national archive storing electronic documents signed with qualified e signatures.
Currently EAIS deals with electronic documents of ADOC and EGAS specifications.

21. Actions in progress PDF-LT specification.
Adjustment of the Law on Documents and Archives.
Transfer of Government decrees (electronic) to EAIS.

22. Summary “Standard-first” approach should be chosen.
ADOC and MDOC specifications were nominated as main strategic innovation 2010 in Lithuania.
Product line Signa was awarded as a winner of national contest “Innovative Product 2011”.
Electronic Archive Information System is unique not only in Lithuania, but also in the world.

25. Simplest signing scheme

26. Simplest validation scheme

27. Advantages of el. documents
Save time and costs of ordinary post services and/or further management.
The scanning costs per year in Lithuania would exceed 10 M€.
Average 3-year ROI of electronic documents management exceeds 300%.
Full reliability of document content, possibility to use fragments for preparation of other documents, possibility to search in a document text.

28. Classification of interoperability solutions

29. Physical structure of el. documents
ZIP-based electronic document (container) format conformant with ETSI TS
XAdES electronic signatures of detached topology according to ETSI TS
Metadata is an integral part of the electronic document, i.e. it is embedded according to ISO
Main document should be stored in root directory. Appendices and attached documents may be stored in one or more directories (maximum number of levels ≤ 3). …

30. Example. Logical-physical mapping

31. ADOC content formats Word processing: docx, odt.
Spreadsheets: xlsx, ods.
Presentations: pptx, ppsx, odp.
Vector graphics and text formats: pdf.
Raster graphics formats: tif, tiff, jpg, jpeg, jfif, png.

32. Electronic document signatures
Signatures standard:
XAdES v1.4.1
Electronic signatures formats:
XAdES-EPES
XAdES-T
XAdES-C
XAdES-X
XAdES-X-L
XAdES-A
Signatures may be:
Parallel
Hierarchic

33. MDOC specification 90 % based on the ADOC v1.0
MDOC specification redefines allowed main document and appendix formats:
Machine readable content formats: xml, ffdata
Visualization formats: css, xslt, fo, mxfd, pdf
Image formats: tif, jpg, png (only for appendixes)
Attachments are not allowed
MDOC specification defines special requirements for content data visualization

34. Software requirements
CWA 14170:2004 Security requirements for signature creation applications
CWA 14171:2004 General guidelines for electronic signature verification
ETSI TS V1.2.1:2002 Time stamping profile
ETSI TS V1.3.3:2007 Qualified certificate profile

35. EAIS public free tools
Web application (available at if compared to Signa Web this application is more beginners oriented, as all the time user is guided by wizards.
Signa Desktop
