E LECTRONIC A RCHIVE I NFORMATION S YSTEM Saulius Ragaišis, Adomas Birštunas, Antanas Mitašiūnas, Arūnas Stočkus Vilnius University, Lithuania MitSoft, software company Baltic DB & IS
Objectives Presentation of Lithuanias 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 specification 2010: MDOC specification
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
M ODEL OF E LECTRONIC D OCUMENT
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 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)
E LECTRONIC A RCHIVE I NFORMATION S YSTEM
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 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 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 Electronic Archive Information System is unique not only in Lithuania, but also in the world.
Q UESTIONS ?
Simplest signing scheme
Simplest validation scheme
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 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). …
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.
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 V1.2.1:2002 Time stamping profile ETSI TS 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
