Anonymous network access using the digital marketplace
With increasing usage of mobile telephony, and the trend towards additional mobile Internet usage, privacy and anonymity become more and more important. Previously-published anonymous communication schemes aim to obscure their users' network addresses, because real-world identity can be easily be derived from this information. We propose modifications to a novel call-management architecture, the digital marketplace, which will break this link, therefore enabling truly anonymous network access
Online Personal Data Processing and EU Data Protection Reform. CEPS Task Force Report, April 2013
This report sheds light on the fundamental questions and underlying tensions between current policy objectives, compliance strategies and global trends in online personal data processing, assessing the existing and future framework in terms of effective regulation and public policy. Based on the discussions among the members of the CEPS Digital Forum and independent research carried out by the rapporteurs, policy conclusions are derived with the aim of making EU data protection policy more fit for purpose in todayâs online technological context. This report constructively engages with the EU data protection framework, but does not provide a textual analysis of the EU data protection reform proposal as such
A Broad Evaluation of the Tor English Content Ecosystem
Tor is among most well-known dark net in the world. It has noble uses,
including as a platform for free speech and information dissemination under the
guise of true anonymity, but may be culturally better known as a conduit for
criminal activity and as a platform to market illicit goods and data. Past
studies on the content of Tor support this notion, but were carried out by
targeting popular domains likely to contain illicit content. A survey of past
studies may thus not yield a complete evaluation of the content and use of Tor.
This work addresses this gap by presenting a broad evaluation of the content of
the English Tor ecosystem. We perform a comprehensive crawl of the Tor dark web
and, through topic and network analysis, characterize the types of information
and services hosted across a broad swath of Tor domains and their hyperlink
relational structure. We recover nine domain types defined by the information
or service they host and, among other findings, unveil how some types of
domains intentionally silo themselves from the rest of Tor. We also present
measurements that (regrettably) suggest how marketplaces of illegal drugs and
services do emerge as the dominant type of Tor domain. Our study is the product
of crawling over 1 million pages from 20,000 Tor seed addresses, yielding a
collection of over 150,000 Tor pages. We make a dataset of the intend to make
the domain structure publicly available as a dataset at

Auto-regulating New Media
Using Foucault's (1977, 1978) notion of panoptic method of governmentality and looking at the case of Singapore's Internet policy, this paper attempts to expand on the idea-and ideals-of 'auto-regulation'(Lee, 2000, pp. 4-5; Lee & Birch, 2000). Auto-regulation, as I shall posit in this paper, provides a way for regulatory enforcement and surveillance to become sufficiently transparent and 'normalised' so that 'the exercise of power may be supervised by society as a whole'(Foucault, 1977, pp.207-208) rather than by a select group of policy and law enforcement officers, or civil society /activist groups
A Decentralised Digital Identity Architecture
Current architectures to validate, certify, and manage identity are based on
centralised, top-down approaches that rely on trusted authorities and
third-party operators. We approach the problem of digital identity starting
from a human rights perspective, with a primary focus on identity systems in
the developed world. We assert that individual persons must be allowed to
manage their personal information in a multitude of different ways in different
contexts and that to do so, each individual must be able to create multiple
unrelated identities. Therefore, we first define a set of fundamental
constraints that digital identity systems must satisfy to preserve and promote
privacy as required for individual autonomy. With these constraints in mind, we
then propose a decentralised, standards-based approach, using a combination of
distributed ledger technology and thoughtful regulation, to facilitate
many-to-many relationships among providers of key services. Our proposal for
digital identity differs from others in its approach to trust in that we do not
seek to bind credentials to each other or to a mutually trusted authority to
achieve strong non-transferability. Because the system does not implicitly
encourage its users to maintain a single aggregated identity that can
potentially be constrained or reconstructed against their interests,
individuals and organisations are free to embrace the system and share in its
benefits.Comment: 30 pages, 10 figures, 3 table
Designing a CompensatedâKidney Donation System
Osteochondral lesions of the talus (OLTs) are the third most common type of osteochondral lesion and can cause pain and instability of the ankle joint. Episurf Medical AB is a medical technology company that develops individualized implants for patients who are suffering from focal cartilage lesions. Episurf have recently started a project that aims to implement their implantation technique in the treatment of OLTs. This master thesis was a part of Episurfâs talus project and the main goal of the thesis was to find the optimal implantation angle of the Episurf implant when treating OLTs. The optimal implantation angle was defined as the angle that minimized the maximum equivalent (von Mises) strain acting on the implant shaft during the stance phase of a normal gait cycle. It is desirable to minimize the strain acting on the implant shaft, since a reduction of the strain can improve the longevity of the implant. To find the optimal implantation angle a finite element model of an ankle joint treated with the Episurf implant was developed. In the model an implant with a diameter of 12 millimeters was placed in the middle part of the medial side of the talar dome. An optimization algorithm was designed to find the implantation angle, which minimized the maximum equivalent strain acting on the implant shaft. The optimal implantation angle was found to be a sagittal angle of 12.5 degrees and a coronal angle of 0 degrees. Both the magnitude and the direction of the force applied to the ankle joint in the simulated stance phase seemed to influence the maximum equivalent strain acting on the implant shaft. A number of simplifications have been done in the simulation of this project, which might affect the accuracy of the results. Therefore it is recommended that further, more detailed, simulations based on this project are performed in order to improve the result accuracy.Fokala broskskador pĂ„ talusbenet Ă€r den tredje vanligaste typen av fokala broskskador och kan ge upphov till smĂ€rta och instabilitet av fotleden. Episurf Medical AB Ă€r ett medicintekniskt företag som utvecklar individanpassade implantat för patienter med fokala broskskador. Episurf har nyligen pĂ„börjat ett projekt dĂ€r deras teknik ska anvĂ€ndas i behandlingen av fokala broskskador pĂ„ talusbenet. Den hĂ€r masteruppsatsen var en del i Episurfs talusprojekt och dess huvudmĂ„l var att finna den optimala implantationsvinkeln av Episurfs implantat i behandlingen av fokala broskskador pĂ„ talusbenet. Den optimala implanteringsvinkeln definierades som den vinkel som minimerade den effektiva von Mises-töjningen som verkade pĂ„ implantatskaftet under stance-fasen i en normal gĂ„ngcykel. Det Ă€r efterstrĂ€vansvĂ€rt att minimera belastningen pĂ„ implantatskaftet eftersom en reducering av belastningen kan förbĂ€ttra implantatets livslĂ€ngd. En finita element-modell av en fotled behandlad med Episurfs implantat utvecklades för att för att finna den optimala implantationsvinkeln. I modellen placerades ett implantat med en diameter pĂ„ 12 millimeter pĂ„ mittendelen av talus mediala sida. En optimeringsalgoritm utformades för att finna implantationsvinkeln som minimerade den effektiva von Mises-töjningen pĂ„ implantatskaftet. Den funna optimala implantationsvinkeln bestod av en vinkel pĂ„ 12.5 grader i sagittalplan och en vinkel pĂ„ 0 grader i koronalplan. BĂ„de storleken och riktningen pĂ„ kraften som applicerats pĂ„ fotleden under den simulerade stance-fasen av gĂ„ngcykeln verkade pĂ„verka belastningen pĂ„ implantatskaftet. Ett antal förenklingar har gjorts i projektets simuleringar, vilket kan pĂ„verka noggrannheten i resultatet. DĂ€rför rekommenderas att ytterligare, mer detaljerade simuleringar baserade pĂ„ det hĂ€r projektet görs för att förbĂ€ttra resultatets noggrannhet
Entrepreneurial Supply Chains and Strategic Collaboration: The Case of BagĂÂČss Cheese in Bagolino, Italy
Many small towns and communities are struggling to sustain their competitiveness in the face of increasing globalization. Yet, through entrepreneurial supply chains, some communities are organizing themselves to forge local solutions to their global challenges. The essence of entrepreneurial supply chains is its ability to facilitate alignment of all participants in the chain, eliminating moral hazard and opportunism risks. It is argued that this governance system and an ability to protect the common assets from infringement by outsiders are necessary for the success of these solutions. The research uses BagĂÂČss cheese, produced in the small Italian village of Bagolino, to illustrate the characteristics of entrepreneurial supply chains and test the effect of the identified necessary conditions for their successful implementation.entrepreneurial supply chain, BagĂÂČss cheese, globalization, International Development, International Relations/Trade, Q10, Q17,
