Ford, CEO Managing Director, Asia Entegra Analytics Public Safety and National Security Microsoft Corporation Employing Information Technology to Combat Human Trafficking | 1 Anti-trafficking advocates, law enforcement agencies (LEAs), governments, nongovernmental organizations (NGOs), and intergovernmental organizations (IGOs) have worked for years to combat human trafficking, but their progress to date has been limited. The issues are especially complex, and the solutions are not simple. Although technology facilitates this sinister practice, technology can also help fight it. Advances in sociotechnical research, privacy, Microsoft and its partners are applying their interoperability, cloud and mobile technology, and industry experience to address technology- data sharing offer great potential to bring state- facilitated crime.

  • Photodna & Photodna Cloud Service
    PhotoDNA & PhotoDNA Cloud Service Fact Sheet PhotoDNA Microsoft believes its customers are entitled to safer and more secure online experiences that are free from illegal, objectionable and unwanted content. PhotoDNA is a core element of Microsoft’s voluntary business strategy to protect its customers, systems and reputation by helping to create a safer online environment. • Every single day, there are over 1.8 billion unique images uploaded and shared online. Stopping the distribution of illegal images of sexually abused children is like finding a needle in a haystack. • In 2009 Microsoft partnered with Dartmouth College to develop PhotoDNA, a technology that aids in finding and removing some of the “worst of the worst” images of child sexual abuse from the Internet. • Microsoft donated the PhotoDNA technology to the National Center for Missing & Exploited Children (NCMEC), which established a PhotoDNA-based program for online service providers to help disrupt the spread of child sexual abuse material online. • PhotoDNA has become a leading best practice for combating child sexual abuse material on the Internet. • PhotoDNA is provided free of charge to qualified companies and developers. Currently, more than 50 companies, including Facebook and Twitter, non-governmental organizations and law enforcement use PhotoDNA. PhotoDNA Technology PhotoDNA technology converts images into a greyscale format with uniform size, then divides the image into squares and assigns a numerical value that represents the unique shading found within each square. • Together, those numerical values represent the “PhotoDNA signature,” or “hash,” of an image, which can then be compared to signatures of other images to find copies of a given image with incredible accuracy and at scale.

  • The Power of Public- Private Partnerships in Eradicating Child Sexual Exploitation
    EXPERT PAPER THE POWER OF PUBLIC- PRIVATE PARTNERSHIPS IN ERADICATING CHILD SEXUAL EXPLOITATION ERNIE ALLEN FOR ECPAT INTERNATIONAL Ernie Allen, Principal, Allen Global Consulting, LLC and Senior Advisor with ECPAT International INTRODUCTION Twenty years ago, the first World Congress Against Commercial Sexual Exploitation of Children awakened the world to the depth and extent of the insidious problem of child sexual exploitation. Since then, progress has been remarkable. Through efforts led by a global network to End Child Prostitution, Child Pornography and Trafficking of Children for Sexual Purposes or ECPAT, more victims are being identified; more offenders are being prosecuted; new laws are being enacted; and public awareness has reached its highest level. Yet child sexual exploitation is a bigger problem today than it was twenty years ago and it remains underreported and underappreciated. Further, with the advent of the internet, it has exploded to unprecedented levels. Prior to the internet, people with sexual interest in children felt isolated, aberrant, and alone. Today, they are part of a global community, able to interact online with those with similar interests worldwide. They share images, fantasies, techniques, even real children. And they do it all with virtual anonymity. In 2013, a man in Sweden was convicted of raping children even though it wasn’t in the same country as his victims, when the assault took place How is that possible? He hired men in the Philippines to obtain children as young as five and assault them while he directed the action and watched via webcam from the comfort of his home. Swedish authorities called it ‘virtual trafficking.’ 1 Last year, law enforcement in the United • The Netherlands has worked with social Kingdom arrested 29 people for the use media including Twitter to remove child of children in Asia as young as six for exploitation images quickly.

  • Building a Better Mousetrap
    ISN_FINAL (DO NOT DELETE) 10/24/2013 6:04 PM SUPER-INTERMEDIARIES, CODE, HUMAN RIGHTS IRA STEVEN NATHENSON* Abstract We live in an age of intermediated network communications. Although the internet includes many intermediaries, some stand heads and shoulders above the rest. This article examines some of the responsibilities of “Super-Intermediaries” such as YouTube, Twitter, and Facebook, intermediaries that have tremendous power over their users’ human rights. After considering the controversy arising from the incendiary YouTube video Innocence of Muslims, the article suggests that Super-Intermediaries face a difficult and likely impossible mission of fully servicing the broad tapestry of human rights contained in the International Bill of Human Rights. The article further considers how intermediary content-control pro- cedures focus too heavily on intellectual property, and are poorly suited to balancing the broader and often-conflicting set of values embodied in human rights law. Finally, the article examines a num- ber of steps that Super-Intermediaries might take to resolve difficult content problems and ultimately suggests that intermediaries sub- scribe to a set of process-based guiding principles—a form of Digital Due Process—so that intermediaries can better foster human dignity. * Associate Professor of Law, St. Thomas University School of Law, inathen- [email protected].

  • Microsoft and the UN Sustainable Development Goals
    Microsoft and the UN Sustainable Development Goals September 2017 Introduction and Context Microsoft’s mission — to empower every person and every organization on the planet to achieve more — aligns strongly with the United Nation’s global agenda for sustainable development from 2015 through 2030. The UN General Assembly articulated that agenda in a set of 17 Sustainable Development Goals (SDGs) seeking to end poverty, protect the planet, and ensure prosperity for all. Each of the United Nation’s goals present challenges bigger than any one organization, or even one sector of society can accomplish alone. At Microsoft, we seek to apply the unique assets that a technology company of our scope and scale has towards the global, multi-sector effort needed to achieve the SDGs. Doing so is both our responsibility and an opportunity to advance societal needs and technology at the same time collaboratively. Microsoft’s commitment to corporate social responsibility requires us to be thoughtful about the impact of our business practices and policies. We believe the way we operate helps contribute to many of the UN SDGs, ranging from our employment practices to our commitments to source renewable energy to the work we do to infuse responsibility across our global supply chain. This white paper focuses on what we feel are our unique contributions: • the application of Microsoft’s products and services to the SDGs, and • our philanthropic and other investments targeted towards fostering the sustainable development of communities around the world. Similarly, while Microsoft’s efforts are helping advance progress towards meeting the broad range of issues covered by all 17 SDGs, we have prioritized 8 SDGs to ensure we leverage our assets for the greatest impact.

  • Practical Use of Approximate Hash Based Matching in Digital Investigations
    Digital Investigation 11 (2014) S18–S26 Contents lists available at ScienceDirect Digital Investigation journal homepage: www.elsevier.com/locate/diin Practical use of Approximate Hash Based Matching in digital investigations Petter Christian Bjelland*, Katrin Franke, André Årnes 1 Norwegian Information Security Laboratory (NISlab), Gjøvik University College, Norway abstract Keywords: Approximate Hash Based Matching (AHBM), also known as Fuzzy Hashing, is used to Digital forensics identify complex and unstructured data that has a certain amount of byte-level similarity. Approximate Matching Common use cases include the identification of updated versions of documents and Evidence analysis fragments recovered from memory or deleted files. Though several algorithms exist, there Data discovery has not yet been an extensive focus on its practical use in digital investigations. The paper Malware forensics addresses the research question: How can AHBM be applied in digital investigations? It fo- cuses on common scenarios in which AHBM can be applied, as well as the potential sig- nificance of its results. First, an assessment of AHBM for digital investigations with respect to existing algorithms and requirements for efficiency and precision is given. Then follows a description of scenarios in which it can be applied. The paper presents three modes of operation for Approximate Matching, namely searching, streaming and clustering. Each of the modes are tested in practical experiments. The results show that AHBM has great potential for helping investigators discover information based on data similarity. Three open source tools were implemented during the research leading up to this paper: Autopsy AHBM enables AHBM in an existing digital investigation framework, sddiff helps under- standing AHBM results through visualization, and makecluster improves analysis of graphs generated from large datasets by storing each disjunct cluster separately.
