Abstract [en]

A common problem in the workplace is sharing digital documents with coworkers. Forsome companies the problem extends to wanting the documentskept internally backedup and controlling which people in the company has rights to read and revise certaindocuments.This paper shows different systems and models for access control, version control,and distribution of the documents that can be used to create asystem that solves theseproblems.One requirement for this system was a user interface where users can upload, down-load and manage access to their documents. Another requirement was a service thathandles version control for the documents, and a way to quickly connect and distributethe documents. The system also needed to be able to handle access control of the ver-sioned documents on document level, referred to as "fine grained access control" in thispaper.These models and systems were evaluated based on aspects of the access control mod-els, version control systems, and distribution systems andprotocols. After evaluating,appropriate selections were made to create a prototype to test the system as a whole.The prototype ended up meeting the goals that Nordicstationset for the project butonly with basic functionality. Functionality for retrieving any version from a docu-ments history, controlling access for the documents at document level, and a simpleweb based user interface for managing the documents.

Abstract [sv]

Att enkelt dela dokument med arbetskollegor är något alla företag har ett behov utav.Ofta är dessa dokument interna och skall hållas inom företaget. Även inom företagetkan det finnas behov av att styra vem som har rätt att läsa ellerrevidera dokumenten.Denna examensarbetesrapport beskriver olika tekniker ochmodeller för accesskon-troll, versionshantering och distribution som kan användas för att implementera ettsystem som kan lösa de nämnda problemen.Ett av kraven för systemet var ett användargränssnitt där användare kan ladda upp ochned sina dokument. Ytterligare krav var att systemet skulleversionshantera dokumenetenoch att användare skall kunna komma åt de olika versionerna.Systemet skulle ocksåkunna hantera åtkomstkontroll på dokumentnivå, något denna examensrapport definerarsom "fine grained access control".För att designa ett sådant system så utredes och utvärderades olika tekniker kringåtkomstkontroll och versionshantering samt distributionav dokumenten. För att testasystemet så utvecklads en prototyp baserad på de valda lösningsmetoderna.Den resulterande prototypen uppfyllde de mål som Nordicstation satte för projektet,dock endast med grundläggande funktionalitet. Stöd för atthämta olika versioner avdokument, kontrollera access till dokumentet nere på dokument nivå och ett webbaseratgränssnitt för att administrera dokumenten.
