se encuentre entre etiquetas HTML. Ahora bien, no cualquier información substancial, se encuentra en este formato. Como he ido encontrando a lo largo de estos años, mucha de esta información fundamental está contenida en un formato de documento portátil o, comúnmente conocido, PDF. Así pues, a lo largo de todo este proyecto se centrarán todos los esfuerzos en lograr acceder a los documentos PDF y recopilar la información contenida en éstos y generar una estructura de objetos que contenga toda la información y contenido del PDF. PDFLab Análisis lexicográfico. Análisis sintáctico. Traducción dirigida por sintaxis. Desencriptación. Decodificación. Documento PDF Estructura de Objetos Una vez especificada la función principal de este sistema, antes de diseñarlo e implementarlo se debe: Realizar un estudio exhaustivo del estado del arte para reafirmar el porqué del proyecto.

All resources, sources, and literature, which I used in preparing or I drew on them, I quote in the thesis properly with stating the full reference to the source. 3 Acknowledgement I would like to thank my advisor, RNDr. Václav Lorenc, for his guidance and advice during my work on this thesis. 4 Abstract The goal of this thesis is to provide an in-depth assessment of the use of PDF (Portable Document Format) file format as an attack vector and the current state of the field of malicious document analysis. First, we provide detailed introduction into the inner organization and structure of PDF files and describe how different features can be used for obfuscation purposes. Next, we survey available options for viewing PDF documents in web browser environment, as well as tools for PDF document analysis. The practical part consists of designing and implementing a web application that serves as framework for malicious document analysis.

  • Implementing Paperless Automation of Accounts Payable Invoices for Small Business Accounting Systems
    Implementing Paperless Automation Of Accounts Payable Invoices For Small Business Accounting Systems Athabasca University MBA Applied Project By Stephen Heath Abstract Technology becomes more powerful at exponential rates, but it often seems we are unable to harness the full benefits, and one of the primary areas where technological capabilities and dreams of what we would do with them are out of sync is the vast amounts of paper that we use in what was supposed to be the era of the paperless office. Reducing paper usage, when done effectively, has significant financial and environmental benefits, and yet business paper continues to be a growth industry. In “The Myth of the Paperless Office”, researchers Abigail Sellen and Richard Harper (2002) have determined that the most successful paper reduction projects are those that have improving business processes as a goal rather than simply eliminating paper. The author of this project has decades of experience in information technology, and has seen numerous multi-company information sharing projects such as EDI come into existence at great expense, be adopted by large companies and their suppliers, and then fail to gain any additional traction. These two observations led to this project, which focuses on providing the essence of a technology which can improve a universal, multi-company business process, using techniques that allow scalability for any size business. The invoicing/accounts payable process was chosen for it’s applicability to almost every business and the large amount of paper printed and stored worldwide as a result of it. The first step was to analyze the invoicing/payables process as it is currently handled and to examine ways it could be made more efficient with cost effective available technology.
