    KĂ€esolevas magistritöös vaadeldakse BDOC ja ASiC-E digitaalselt allkirjastatud dokumendikonteinerite sisu ning kirjeldatakse nende huvipakkuvaid omadusi. Teatava hulga nĂ€idiskonteinerite vaatlemise jĂ€rel pakub autor vĂ€lja faili pĂ€ise ja faili jaluse kombinatsiooni (signatuuri), mis oluliselt parandab nimetatud failide kustutatud olekust sihitud taastamist kĂŒlgnevatest klastritest NTFS vormindatud tihendamata kettal, vĂ”ttes arvesse klassikalise kĂ”vaketta geomeetriat. Ühtlasi kirjeldab autor kohtuekspertiisi koha pealt tĂ€hendust omavaid andmeid ZIP kohaliku faili pĂ€ises ja keskkataloogi kirjes, XML signatuuris ja ASN.1 kodeeritud kihtides ning nende kĂ€ttesaamise algoritmi. Nendele jĂ€reldustele tuginedes loob autor Phytoni skripte ja viib lĂ€bi mitmeid teste failide taastamiseks faili signatuuri jĂ€rgi ning huvipakkuvate andmete vĂ€ljavĂ”tmiseks. Teste viiakse lĂ€bi teatava valiku failide ĂŒle ja tulemusi vĂ”rreldakse mitme kohtuekspertiisis laialt kasutatava peavoolu töökeskkonnaga, samuti mĂ”ningate andmetaaste tööriistadega. LĂ”puks testitakse magistritöö kĂ€igus pakutud digitaalselt allkirjastatud dokumentide taastamiseks mĂ”eldud signatuuri ja andmete vĂ€ljavĂ”tmise algoritmi suurel hulgal avalikust dokumendiregistrist pĂ€rit kehtivate dokumentidega, mis saadi kĂ€tte spetsiaalselt selleks kirjutatud veebirobotiga. Nimetatud teste viiakse lĂ€bi dokumentide ĂŒle, mille hulgas on nii digitaalselt allkirjastatud dokumente kui ka teisi, nendega struktuurilt sarnaseid dokumente.This thesis reviews the contents and observes certain properties of digitally signed documents of BDOC and ASiC-E container formats. After reviewing a set of sample containers, the author comes up with a header and footer combination (signature) significantly improving pinpointed carving-based recovery of those files from a deleted state on NTFS formatted uncompressed volumes in contiguous clusters, taking into account the geometry of classic disk drives. The author also describes forensically meaningful attributive data found in ZIP Headers and Central Directory, XML signatures as well as embedded ASN.1 encoded data of the sample files and suggests an algorithm for the extraction of such data. Based on these findings, the author creates scripts in Python and executes a series of tests for file carving and extraction of attributive data. These tests are run over the samples placed into unallocated clusters and the results are compared to several mainstream commercial forensic examination suites as well as some popular data recovery tools. Finally, the author web-scrapes a large number of real-life documents from a government agency’s public document registry. The carving signature and the data-extractive algorithm are thereafter applied on a larger scale and in an environment competitively supplemented with structurally similar containers

    Authors and Creative Users : Addressing the Conceptual Challenges of Digital Creativity to EU Copyright Law from the Perspective of the Author

    Get PDF
    To be an “author” might mean many different things, depending on the context in which the word is used. This thesis explores the EU copyright’s concept of author and how it relates to the everyday digital creativity on the Internet. It invites to consider what EU copyright law might look like if the digital creators which this thesis calls Creative Users were included in the legal system as “authors”. For this purpose, the thesis analyses the concept of author in EU copyright law through its history and theory and several conceptualisations that can be seen to characterise what “author” is in the European copyright tradition are identified. These conceptualisations are then used to deepen the understanding of the current EU copyright law and to reflect on two examples of Creative User activities: the collective knowledge production of Wikipedia and the transformative cultural communication of Internet memes. This thesis proposes that to integrate potential new forms of authorship, a compromise could be found between the different ways of conceptualising the author. It is suggested that if the author that is presently guaranteed a high level of protection under EU copyright law were to be treated as a flexible and more inclusive concept and allowed to evolve together with cultural and technological change, it should influence how copyright protection and exploitation are approached as well

    Architectures and Standards for Spatial Data Infrastructures and Digital Government: European Union Location Framework Guidelines

    Get PDF
    This document provides an overview of the architecture(s) and standards for Spatial Data Infrastructures (SDI) and Digital Government. The document describes the different viewpoints according to the Reference Model for Open and Distributed Processing (RM-ODP) which is often used in both the SDI and e-Government worlds: the enterprise viewpoint, the engineering viewpoint, the information viewpoint, the computational viewpoint and the technological viewpoint. The document not only describes these viewpoints with regard to SDI and e-Government implementations, but also how the architecture(s) and standards of SDI and e-Government relate. It indicates which standards and tools can be used and provides examples of implementations in different areas, such as process modelling, metadata, data and services. In addition, the annex provides an overview of the most commonly used standards and technologies for SDI and e-Government.JRC.B.6-Digital Econom

    External auditing and corporate governance perspectives in a small state: the case of Malta

    Get PDF
    This thesis stems from academic research following my MPhil in 1992. It presents a portfolio of fourteen selected papers offering insights on major issues affecting the accountancy-related areas of external auditing (EA) and corporate governance (CG) in the small state of Malta. The commentary (Chapter 1) presents a background to the development of the portfolio and overviews the theoretical framework and methodology. It then introduces each paper, underlining common sub-themes. The contributions of the papers to knowledge are then indicated by (i) overviewing the development of each sub-theme contributing to the academic discourses in EA and CG, and (ii) laying out the relevance to the wider debates relating to small state literature. The commentary concludes by looking at the follow-up research agenda and the beckoning future. Chapters 2 to 15 then reproduce fourteen papers an introductory paper and thirteen others in two parts. The introductory paper includes most major small state sub-themes recurring in different ways in the subsequent papers: issues relating to close relationships and independence, discipline, resistance to change, regulation, secrecy, small business units and other small state issues. The following first part includes seven papers on Maltese external auditing in owner-managed companies, auditor changes, auditor perceptions, qualified opinions, first-time auditor selection, fee development and dysfunctional audit behaviour. The second part then comprises six papers on Maltese CG including the CG statement, internal audit benchmarking, conflicts of interest in co-operatives, the board/management relationship, a CG index, and small shareholder participation in the AGM. The portfolio contributes to literature notably by its original highlighting of the significance of the above-mentioned sub-themes on various aspects of EA and CG in a small state. Furthermore, the portfolio impacts Maltese EA and CG practices, particularly by emphasising the need to go beyond the adoption of imported regulatory framework
