Vulnerability Report Attacks Bypassing Confidentiality in Encrypted PDF
Vulnerability Report Attacks bypassing confidentiality in encrypted PDF Jens M¨uller1, Fabian Ising2, Vladislav Mladenov1, Christian Mainka1, Sebastian Schinzel2, J¨orgSchwenk1 May 16, 2019 1Chair for Network and Data Security 2FH M¨unsterUniversity of Applied Sciences Abstract In this report, we analyze PDF encryption and show two novel techniques for breaking the confidentiality of encrypted documents. Firstly, we abuse the PDF feature of partially encrypted documents to wrap the encrypted part of the document within attacker-controlled content and therefore, exfiltrate the plaintext once the document is opened by a legitimate user. Secondly, we abuse a flaw in the PDF encryption specification allowing an attacker to arbitrarily manipulate encrypted content without knowing the cor- responding key/password. The only requirement is one single block of known plaintext, which we show is fulfilled by design. By using exfiltration channels our attacks allow the recovery of the entire plaintext or parts of it within an encrypted document. The attacks rely only on standard compliant PDF features. We evaluated our attacks on 27 widely used PDF viewers and found all of them vulnerable. 1 Contents 1 Background4 1.1 Portable Document Format (PDF) . .4 1.2 PDF Encryption . .6 1.3 PDF Interactive Features . .7 2 Attacker Model8 3 PDF Encryption: Security Analysis9 3.1 Partial Encryption . .9 3.2 CBC Malleability . 10 3.3 PDF Interactive Features . 12 4 How To Break PDF Encryption 14 4.1 Direct Exfiltration (Attack A) . 14 4.1.1 Requirements . 15 4.1.2 Direct Exfiltration through PDF Forms (A1) . 15 4.1.3 Direct Exfiltration via Hyperlinks (A2) . -

Since documents exist mostly in digital format on the web, people may spend a large part of their time on browsing or searching on the web to look for useful information. However, this used to be a one-way interaction with users having few options to mark texts or to highlight important sections in a web document; what’s more, it is difficult to add extra information as reference on web pages, which is useful for further reference or sharing with friends. -
Semantic Annotation Framework for Web Extracted Data

Gnana Chithra Equity Research Consultant, Angeeras Securities, Chennai, Tamilnadu, India Dr. E. Ramaraj Professor, Department of Computer Science and Engineering, Alagappa University, Karaikudi, Tamilnadu, India ABSTRACT Semantic annotation of web pages is the state of art technology for achieving the unified objective of attaining Semantic web Universe, which enables sharing, and reusing the document content beyond the boundaries and applications. Web is a treasury of knowledge and efficient tools should be designed to explore the structured and unstructured data. Annotating million of web pages manually is an impossible task. For high information retrieval rates, automatic annotation of documents is mandatory. Metadata is added to the web pages to make it intelligent for processing in content based intelligent applications. This paper analyses the problems with the current Semantic annotation systems and proposes a new Ontology based Automatic annotation system Framework. Ontology based semantic annotation is one of the best methods for extracting data from the Knowledge Base. The integration of Modified Manning’s Sentence boundary detection algorithm and Noun Phrase Collocation algorithm and classification using machine learning techiques in the Information Extraction module, and developing a new data model and ontology for Structured Ontology engineering model is contributed in this paper. -
A Semantic Web Annotation Tool for a Web-Based Audio Sequencer
A semantic web annotation tool for a web-based audio sequencer Luca Restagno1, Vincent Akkermans2, Giuseppe Rizzo1, and Antonio Servetti1 1 Dipartimento di Automatica e Informatica, Politecnico di Torino, Torino, Italy, [email protected], [email protected], [email protected], 2 Music Technology Group, Universitat Pompeu Fabra, Barcelona, Spain, [email protected] Abstract. Music and sound have a rich semantic structure which is so clear to the composer and the listener, but that remains mostly hidden to computing machinery. Nevertheless, in recent years, the introduction of software tools for music production have enabled new opportunities for migrating this knowledge from humans to machines. A new generation of these tools may exploit sound samples and semantic information coupling for the creation not only of a musical, but also of a “semantic” compo- sition. In this paper we describe an ontology driven content annotation framework for a web-based audio editing tool. In a supervised approach, during the editing process, the graphical web interface allows the user to annotate any part of the composition with concepts from publicly avail- able ontologies. As a test case, we developed a collaborative web-based audio sequencer that provides users with the functionality to remix the audio samples from the Freesound website and subsequently annotate them. The annotation tool can load any ontology and thus gives users the opportunity to augment the work with annotations on the structure of the composition, the musical materials, and the creator’s reasoning and intentions. We believe this approach will provide several novel ways to make not only the final audio product, but also the creative process, first class citizens of the Semantic Web. -

1 Annotated Bibliography, and Summaries I. Annotating Text II. Annotating Media III. Annotation Theory and Practice IV. Group Dynamics and Social Annotation V. Bibliographic Reference/Metadata/Tagging Note to Reader: The categories of this bibliography have been separated into ‘Tools’ and ‘Articles’ for ease of reading. Cross-posted entries have been marked with an asterisk (*) after their first appearance. Category I: Annotating Text This category provides an environmental scan of the current state of text-based annotation practices and the foundational tools in the discipline. Many of the publications focus on situating annotation in the field of digital humanities by drafting definitions for annotation practice; specifying a general annotation framework for commentary across mediums; or brainstorming platforms that would better support user interaction with objects and with each other. Authors remark that the evolution of scholarship brought about by interactive Web 2.0 practices shifted the focus from learner-content interaction to learner-learner interaction, and that this behavioural shift necessitates a redesign of tools (Agosti et al. 2005; Gao 2013). It is widely acknowledged that annotation practices are beneficial for learning, archiving, clarifying, sharing, and expanding; current Web architecture, however, struggles to facilitate these advantages (Agosti et al. 2012; Bottoni 2003; Farzan et al. 2008). Several publications introduce tools that bridge the gap between tool design and user needs, specifically AnnotatEd and CommentPress (Farzan et al. 2008; Fitzpatrick 2007). These tools, along with alternative platforms that gamify annotation, allow for interactive reading and support user engagement with resources in a customizable way. The tools treat documents as mutable objects that can be tagged, highlighted, and underlined. -

THE VALUE OF PLURALITY IN ‘THE NETWORK WITH A THOUSAND ENTRANCES’1 RAY SIEMENS, ALYSSA ARBUCKLE, LINDSEY SEATTER, RANDA EL KHATIB, and TRACEY EL HAJJ, with the ETCL Research Group Abstract This contribution reflects on the value of plurality in the ‘network with a thousand entrances’ suggested by McCarty (http://goo.gl/H3HAfs), and others, in association with approaching time-honoured annotative and commentary practices of much-engaged texts. The question is how this approach aligns with tensions, today, surrounding the multiplicity of endeavour associated with modeling practices of annotation by practitioners of the digital humanities. Our work, hence, surveys annotative practice across its reflection in contemporary praxis, from the MIT annotation studio whitepaper (http://goo.gl/8NBdnf) through the work of the Open Annotation Collaboration (http://www.openannotation.org), and manifest in multiple tools facilitating annotation across the web up to and including widespread application in social knowledge creation suites like Wikipedia https://en.wikipedia.org/wiki/Web annotation) Keywords: annotative practices, semantic web practices, reader-reader interaction, annotation tools, social annotation, folksonomy, content modelling, process modelling Annotation is one of the important ‘primitive’ activities that scholars in many disciplines employ when they pursue a topic of interest [Unsworth 2000]. As more and more of the scholarly process has been enhanced by, International Journal of Humanities and Arts Computing 11.2 (2017): 153–173 DOI: 10.3366/ijhac.2017.0190 © Edinburgh University Press 2017 www.euppublishing.com/ijhac 153 Ray Siemens et al. and in some cases migrated to, digital formats the need to create tools that permit scholars to enjoy the same broad range of primitive activities that they do with physical formats has become evident. -
