In this chapter, the authors provide an exhaustive survey of tracking-related identification techniques, which are often applied against the will and preferences of the users of the Web, and therefore violate their privacy one way or another. After discussing the motivations behind the information-collecting activities targeting Web users (i.e., profiling), and the nature of the information that can be collected by various means, the authors enumerate the most important techniques of the three main groups of tracking, namely storage-based tracking, history stealing, and fingerprinting. The focus of the chapter is on the last, as this is the field where both the techniques intended to protect users and the current legislation are lagging behind the state-of-the-art technology; nevertheless, the authors also discuss conceivable defenses, and provide a taxonomy of tracking techniques, which, to the authors’ knowledge, is the first of its kind in the literature. At the end of the chapter, the authors attempt to draw the attention of the research community of this field to new tracking methods.

    Yee et al. The Tablecast Data Publishing Protocol The Tablecast Data Publishing Protocol Ka-Ping Yee Dieterich Lawson Google Medic Mobile [email protected] [email protected] Dominic König Dale Zak Sahana Foundation Medic Mobile [email protected] [email protected] ABSTRACT We describe an interoperability challenge that arose in Haiti, identify the parameters of a general problem in crisis data management, and present a protocol called Tablecast that is designed to address the problem. Tablecast enables crisis organizations to publish, share, and update tables of data in real time. It allows rows and columns of data to be merged from multiple sources, and its incremental update mechanism is designed to support offline editing and data collection. Tablecast uses a publish/subscribe model; the format is based on Atom and employs PubSubHubbub to distribute updates to subscribers. Keywords Interoperability, publish/subscribe, streaming, synchronization, relational table, format, protocol INTRODUCTION After the January 2010 earthquake in Haiti, there was an immediate need for information on available health facilities. Which hospitals had been destroyed, and which were still operating? Where were the newly established field clinics, and how many patients could they accept? Which facilities had surgeons, or dialysis machines, or obstetricians? Aid workers had to make fast decisions about where to send the sick and injured— decisions that depended on up-to-date answers to all these questions. But the answers were not readily at hand. The U. S. Joint Task Force began a broad survey to assess the situation in terms of basic needs, including the state of health facilities. The UN Office for the Coordination of Humanitarian Affairs (OCHA) was tasked with monitoring and coordinating the actions of the many aid organizations that arrived to help.

  • OSINT Handbook September 2020
    OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 Aleksandra Bielska Noa Rebecca Kurz, Yves Baumgartner, Vytenis Benetis 2 Foreword I am delighted to share with you the 2020 edition of the OSINT Tools and Resources Handbook. Once again, the Handbook has been revised and updated to reflect the evolution of this discipline, and the many strategic, operational and technical challenges OSINT practitioners have to grapple with. Given the speed of change on the web, some might question the wisdom of pulling together such a resource. What’s wrong with the Top 10 tools, or the Top 100? There are only so many resources one can bookmark after all. Such arguments are not without merit. My fear, however, is that they are also shortsighted. I offer four reasons why. To begin, a shortlist betrays the widening spectrum of OSINT practice. Whereas OSINT was once the preserve of analysts working in national security, it now embraces a growing class of professionals in fields as diverse as journalism, cybersecurity, investment research, crisis management and human rights. A limited toolkit can never satisfy all of these constituencies. Second, a good OSINT practitioner is someone who is comfortable working with different tools, sources and collection strategies. The temptation toward narrow specialisation in OSINT is one that has to be resisted. Why? Because no research task is ever as tidy as the customer’s requirements are likely to suggest. Third, is the inevitable realisation that good tool awareness is equivalent to good source awareness. Indeed, the right tool can determine whether you harvest the right information.

  • Dissertation Submitted to the Graduate Faculty of Auburn University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy
    Repatterning: Improving the Reliability of Android Applications with an Adaptation of Refactoring by Bradley Christian Dennis A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 2, 2014 Keywords:Refactoring, Code Smells, Patterns, Non-functional Requirements, Verification Copyright 2014 by Bradley Christian Dennis Committee: David Umphress, Chair, Associate Professor of Computer Science and Software Engineering James Cross, Professor of Computer Science and Software Engineering Dean Hendrix, Associate Professor of Computer Science and Software Engineering Jeffrey Overbey, Assistant Research Professor of Computer Science and Software Engineering Abstract Studies of Android applications show that NullPointerException, OutofMemoryError, and BadTokenException account for a majority of errors observed in the real world. The technical debt being born by Android developers from these systemic errors appears to be due to insufficient, or erroneous, guidance, practices, or tools. This dissertation proposes a re- engineering adaptation of refactoring, called repatterning, and pays down some of this debt. We investigated 323 Android applications for code smells, corrective patterns, or enhancement patterns related to the three exceptions. I then applied the discovered patterns to the locations suggested by the code smells in fifteen randomly selected applications. I measured the before and after reliability of the applications and observed a statistically significant improvement in reliability for two of the three exceptions. I found repatterning had a positive effect on the reliability of Android applications. This research demonstrates how refactoring can be generalized and used as a model to affect non-functional qualities other than the restructuring related attributes of maintainability and adaptability.

  • Bittorrent (Protocol) 1 Bittorrent (Protocol)
    BitTorrent (protocol) 1 BitTorrent (protocol) BitTorrent is a peer-to-peer file sharing protocol used for distributing large amounts of data over the Internet. BitTorrent is one of the most common protocols for transferring large files and it has been estimated that peer-to-peer networks collectively have accounted for roughly 43% to 70% of all Internet traffic (depending on geographical location) as of February 2009.[1] Programmer Bram Cohen designed the protocol in April 2001 and released a first implementation on July 2, 2001.[2] It is now maintained by Cohen's company BitTorrent, Inc. There are numerous BitTorrent clients available for a variety of computing platforms. As of January 2012 BitTorrent has 150 million active users according to BitTorrent Inc.. Based on this the total number of monthly BitTorrent users can be estimated at more than a quarter billion.[3] At any given instant of time BitTorrent has, on average, more active users than YouTube and Facebook combined. (This refers to the number of active users at any instant and not to the total number of unique users.)[4][5] Description The BitTorrent protocol can be used to reduce the server and network impact of distributing large files. Rather than downloading a file from a single source server, the BitTorrent protocol allows users to join a "swarm" of hosts to download and upload from each other simultaneously. The protocol is an alternative to the older single source, multiple mirror sources technique for distributing data, and can work over networks with lower bandwidth so many small computers, like mobile phones, are able to efficiently distribute files to many recipients.
