Denna rapport presenterar ett utvecklingsarbete av standardiserade tillvägagångssätt för att bygga ett ramverk för dokumentsignering. Studien fokuserar på tre olika delar av dokumentsigneringen. De tre delarna är identitetsautentisering, signering och verifiering av signering samt versionshantering. Efter att ha utfört en undersökning konstaterades det att den mest lämpliga lösningen för detta system är att använda X.509v3-certifikat som autentiseringsmetod för identiteter, tillsammans med en PKI( Public Key Infrastructure). För signering och verifiering så används digitala signaturer tillsammans med algoritmerna SHA-2 samt RSA, vilket är två välkända och populära tillvägagångsätt i dessa sammanhang. Andra tillvägagångssätt har diskuterats samt framtida utvecklingsmöjligheter och förbättringar. / This report presents an investigation into different standardized approaches to building a framework for document signing. The study focuses on three different parts of document signing. The three parts are identity authentication, signing and verification of signing and version management. Through the investigation of standards in the market, it was found that a solution using X.509v3 certificates as an authentication method for identities together with a PKI (Public Key Infrastructure) was best suited for this system. For signing and verification, digital signatures are used together with the algorithms SHA-2 and RSA, which are two well-known and popular approaches in these contexts. Other approaches have been discussed as well as future development possibilities and improvements. / Datateknik, Dokumenthantering, Säkerhet, Dokumentsäkerhet

The focus of this diploma thesis is a development of advanced web application for. The purpose of the application is extended .docx files management including import, editing, storage and creating new documents. The development comprises analysis, setting the requirements for the application, analysis of the Java Enterprise Edition and Office Open XML standard for the .docx file format. The thesis further deals with design, implementation and testing the application.

La présente thèse se propose de résoudre les problématiques de facilités de contrôle optique d’un document de sécurité pourvu d’un hologramme par l’application d’une structure optique complexe mettant en œuvre les modes de plasmons de surface. Dans une partie dédiée nous démontrerons l’adaptation de la transmission extraordinaire plasmonique à travers une couche métallique continue ; un concept de sécurité sera aussi présenté permettant l’observation et l’authentification de l’effet transmissif. Dans une autre partie nous présentons un effet de réflexion plasmonique extraordinaire. En lieu et place des phénomènes classiques d’absorption sur une couche métallique épaisse, nous présentons un phénomène que nous avons nommé balance énergétique à médiation plasmonique. Cet effet est bien évidemment mis en évidence à travers un concept final adapté au domaine de l’optique de sécurité / The aim of this PhD thesis is to find optical solutions based on plasmon modes excitation for the control and the authentication of optical security documents. We developed complex optical structures for the excitation of plasmon modes in order to create “easy to catch” and “easy to check" effect. In the first part of the thesis we demonstrated the extraordinary optical transmission through a thin corrugated metallic layer using the Long range plasmon mode; a concept of optical document security is demonstrated. In a second part of the thesis we developed an unusual plasmon effect in reflexion. Instead of having absorption of the spectrum due to the plasmon excitation, we have reflection of the spectrum due to the plasmon excitation using higher diffracted orders. We call this effect "reflection switch" mediated by plasmon. At the end we developed the concept to an optical security document
