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.
2000: Law on Electronic Signature
2006: “Tool-first” approach (e.g., Justa)
2007: e-Servicing (Declaration) System of the Insurers (EDAS)
2008: Minimal requirements for the specifications 2009: ADOC specification2010: MDOC specification
2009: public free software tools2009: 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
MODEL OF ELECTRONIC DOCUMENT
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.
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
Official electronic documents
• Should be adequate to the conventional documents
• Consist of three parts:- content, - signatures,- metadata.
Logical structure of el. document
Current el. document specifications
Product line Signa
• Signa Desktop – public free Windows OS application (download from http://www.mitsoft.lt/)
• Signa Web – public free web application (available at https://signa.mitsoft.lt/)
• 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)
ELECTRONIC ARCHIVE INFORMATION SYSTEM
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.
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).
EAIS main parts
• Public portal• Internal portal• Storage of electronic documents:
- physically located in Vilnius and Šiauliai- data replication- accessible through internal portal only
EAIS subsystems
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
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.
Actions in progress
• PDF-LT specification.• Adjustment of the Law on Documents and
Archives.• Transfer of Government decrees (electronic)
to EAIS.
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.

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.
Classification of interoperability solutions
Physical structure of el. documents
• ZIP-based electronic document (container) format conformant with ETSI TS 102 918
• XAdES electronic signatures of detached topology according to ETSI TS 101 903
• Metadata is an integral part of the electronic document, i.e. it is embedded according to ISO 15489-1
• 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).
• …
Example. Logical-physical mapping
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.
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
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
Software requirements
• CWA 14170:2004 Security requirements for signature creation applications
• CWA 14171:2004 General guidelines for electronic signature verification
• ETSI TS 101 861 V1.2.1:2002 Time stamping profile
• ETSI TS 101 862 V1.3.3:2007 Qualified certificate profile
EAIS public free tools
• Web application (available at https://adoc.archyvai.lt); if compared to Signa Web this application is more beginners oriented, as all the time user is guided by wizards.
• Signa Desktop
