I have the pleasure of welcoming you to this year’s Interdisciplinary Information Management Talks. 2004 is a very special year for Europe, and also for IDIMT: Our IDIMT conferences have become an inner-European event and I would like to welcome all of you as our European partners. The European Union has become a Federation of some 450 million inhabitants, covering some 4 million square km. And we are proud to have been a small cogwheel in this process: IDIMT started back in 1993 when several of our partners had barely overcome the hardships of communist regime and from that time on the integration of our small central-European event has grown, in diversity and in depth. Huge imperia have existed in the past: China, Rome, Persia, Soviet Union. They only lasted as long as the ruling person or oligarchy was able to maintain power and control: a strong army, a strict bureaucracy. The individual subjects of these imperia were often unaware of their fellow countrymen far away, and often not even aware of the central power. Europe is now to be based on different foundations: the free will of its people and on democracy, as expressed by a common parliament and free elections. It is the intention that Europe become a closely knit society gaining the profits of synergy – let the whole be more than its parts – the founding premise of systems thinking. A key issue to this European vision is Information and its Management: the central theme of IDIMT. Only technology – together with a sound theoretical foundation is able to provide Europe- wide access and interchange of information. This year’s program reflects these European needs: • The European society has to be based on electronic information interchange: „E-Society - Perspectives and Risks for European Integration“ • Beyond information we need collaboration: „Cooperative Information Environments“ • Coming generation will have to use modern means and technologies more effectively: „Educational Aspects of Computer and Information Science“ • Small enterprises, the backbone of the European economy will be based more and more on knowledge: “Information and Knowledge Services for SMEs“ • Authenticity, Truth and Trust are one of the foundations of an efficient economy and the keys to personal and economic cooperation: „Creditworthiness as a Requisitely Holistic/Systemic Information?” • All these issues must be discussed in view of the dramatic changes in technology: „Information Technology - from Trends to Horizons”„ Thus IDIMT 2004 covers many of the most relevant issues in ACT and as a consequence of importance to an integrated Europe; or as Profs. Ehleman and Vodacek formulated in back in 1993: “… managerial thinking and management systems have been rapidly undergoing substantial, sometimes even painful changes. The political transition … [and] the transformation to the market type economy have created quite new tasks and problems we were not used to.” With respect to the organisation of IDIMT 2004 I have the pleasant task of thanking our supporters and sponsors: • Our sincere thanks go to the Austrian Government for supporting the publication of our proceedings. • Our thanks include the Austrian and the Czech tax payers. I feel the obligation to provide some return on investment by enlarging their knowledge and understanding and by documenting our conference. Hopefully this will improve their social and economic environment in the long run. • I want to express our thanks to the two universities: The University of Economics Prague and the J. Kepler University Linz for providing the infrastructure for the preparation of IDIMT 2004. We must not forget all those persons who have contributed to its realization: • The organising chairman Petr Doucek and his team, • Christian Hofer for handling all aspects of the scientific programme, • the keynoters and session organiser forming the programme committee, • Christian Hofer additionally for co-editing the proceedings, • all submitters of interesting and challenging papers, • all participants for their contribution to this interdisciplinary exchange of know-how and ideas. May IDIMT 2004 again provide you with new ideas, new concepts and new friendships in a truly European Spirit. I conclude with my sincerest wishes for successful Interdisciplinary Information Management Talks 2004. Gerhard Chroust Linz, July 2004 PREFACE Welcome to the 12th IDIMT-conference. For the second time the conference takes place in Budweis and we are happy that we found such an excellent place for exchanging our thoughts and ideas. But this little old town offers much more than just an environment for the conference: There are a lot of beautiful sights, many friendly people and great eating places offering delicious food and drinks. And last but not least: There is one of the most famous beer breweries of the world within walking distance … Started in 1995 as a small conference between Czech and Austrian scientists in the little village of Kobuva Hut in the Bohemian Forest the conference improved constantly during the years. The originally small kernel of scientists is extending year by year with new faces and bringing in fresh ideas and new spirit. This scientifically and geographically diverse composition of the community is one of the most important success factors for this event and makes it so valuable for all of us. The quality of contributions improved from conference to conference as well as the number of participants increased constantly. This year we have participants from 10 different countries and for the first time we have participants from France and Pakistan. Finally we accepted 24 papers and again the reviewer had a lot of work to do in reviewing and selecting the papers from the submitted ones. Over the years many things changed, but the fundamental idea of the conference remained alike: Providing a solid base for an interdisciplinary and informal exchange of thoughts and interests about economical, technological, and sociological topics. The holistic interchange of concepts and ideas is one of the strengths of the IDIMT and thus makes it so valuable for all participants. This year we kept the well-proved structure of the previous conferences with no major changes: 1. Again the conference takes place at the same time period like last year. As proven many times mid of September seems to be an ideal date for our conference. One the one hand vacation time is over for most of the participants on the other hand winter term has not been started yet and allows university members to attend the conference before lectures start. 2. The conference runs for two full days - Thursday and Friday - again, because the last years showed that two “full time” days are ideal for all participants. The conference starts with dinner on Wednesday evening, the official opening starts on Thursday morning with an invited lecture. Early Friday afternoon the conference closes and allows participants to travel home comfortable. 3. This year we continue with the well-proved structure of the sessions. Every session will be opened by the presentation of one keynote paper and followed by short presentation of several position papers. Again we ensure that there is plenty of time for an intensive follow-on discussion allowing an active participation for all participants. The main focus of this year’s conference will be in the challenges, advantages and problems brought by the ability to electronically interconnect the society, by using cooperative information environments. Special attention will be given to questions of technology trends, information and knowledge services, as well as educational aspects. This year’s themes are: • Information Technology - from Trends to Horizons Invited Speaker: Dr. Christian Loesch • E-Society - Perspectives and Risks for European Integration Keynote Speaker: Dr. Petr Doucek, Session Organizer: Dr. Michael Sonntag • Cooperative Information Environments Keynote Speaker: Prof. Tom Gross, Session Organizer: Konrad Klöckner • Creditworthiness as a Requisitely Holistic/Systemic Information Keynote Speakers: Prof. Matjaz Mulej and Prof. Jozica Knez-Riedl, Session Organizer: Alexander Rebjonok • Educational Aspects of Computer and Information Science Keynote

DESCRIPTORS *Access to Information; Computer Oriented Programs; *Electronic Libraries; *Information Retrieval; Library Automation; Online Catalogs; *Preservation; Standards IDENTIFIERS Digital Technology; *SGML ABSTRACT This report explores the suitability of Standard Generalized Markup Language (SGML) as a framework for building, managing, and providing access to digital libraries, with special emphasis on preservation and access issues. SGML is an international standard (ISO 8879) designed to promote text interchange. It is used to define markup languages, which can then encode the logical structure and content of any so-defined document. The connection between SGML and the traditional concerns of preservation and access may not be immediately apparent, but the use of descriptive markup tools such as SGML is crucial to the quality and long-term accessibility of digitized materials. Beginning with a general exploration of digital formats for preservation and access, the report provides a staged technical tutorial on the features and uses of SGML. The tutorial covers SGML and related standards, SGML Document Type Definitions in current use, and related projects now under development. A tiered metadata model is described that could incorporate SGML along with other standards to facilitate discovery and retrieval of digital documents.

  • Data Hiding and Detection in Office Open Xml (Ooxml) Documents
    DATA HIDING AND DETECTION IN OFFICE OPEN XML (OOXML) DOCUMENTS by Muhammad Ali Raffay A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Applied Science (MASc) in Electrical and Computer Engineering Faculty of Engineering and Applied Science University of Ontario Institute of Technology Oshawa, Ontario, Canada March, 2011 Copyright ©Muhammad Ali Raffay, 2011 Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Muhammad Ali Raffay ii Abstract With the rapid development and popularity of information technology, criminals and mischievous computer users are given avenues to commit crimes and malicious activities. One of the commonly used tactics, called steganography, is to hide information under a cover media so that except participants, no one else knows the existence of such information. Many techniques have been proposed for hiding data in images, videos and audios, but there is not much research devoted to data hiding in the popular MS Office documents which have recently adopted Office Open XML (OOXML) format. In this research, we first focus on identifying several data hiding techniques for OOXML documents. Then, we design and develop a fast detection algorithm based on the unique internal structure of OOXML documents, which contains multiple XML files, by using multi-XML query technique. Experimental results show the proposed detection algorithm outperforms the traditional one in terms of detection speed and completeness, where performance is the key to success of detecting hidden data in OOXML documents due to the fact that millions of documents are generated and transferred over the internet every day.

    WWW.VIRUSBULLETIN.COM/CONFERENCE 2019 LONDON 2 – 4 October 2019 STATIC ANALYSIS METHODS FOR DETECTION OF MICROSOFT OFFICE EXPLOITS Chintan Shah McAfee, India [email protected] ABSTRACT Despite recent advances in exploitation strategies and exploit mitigation techniques, fundamental infection vectors remain the same. It is critical to advance security solutions to inspect both new and known infection vectors in order to successfully mitigate targeted attacks. Apparently, the use of lure documents has become one of the most favoured attack strategies for infi ltrating target organizations. Recently, some of the most high impact attacks using this conventional technique have been uncovered by the security community. In this paper, we present an exploit detection tool that we built for the purpose of detecting malicious lure documents. This detection engine employs multiple binary stream analysis techniques for fl agging malicious Offi ce documents, supporting static analysis of RTF, Offi ce Open XML and Compound Binary File format (MS-CFB). The use, by attackers, of weaponized lure documents necessitates deeper inspection of these fi le formats at the perimeter. Object Linking and Embedding exposes a rich attack surface which has been abused by attackers over the past few years to hide malicious resources. For instance, OOXML fi les can be used to load OLE controls which can eventually facilitate remote code execution. Our proposed detection tool is built to extract embedded storage streams, OLE objects, etc. and apply binary stream analysis techniques over it, in addition to inspecting specifi c fi le sections and analysing embedded scripts, to identify malicious code. This detection tool had been tested over a wide set of in-the-wild exploits and variants.
