  • Open Source Software and Goverment Policy in South
    OPEN SOURCE SOFTWARE AND GOVERNMENT POLICY IN SOUTH AFRICA Minnaar Pieters Thesis submitted in fulfilment of the requirements for the degree of Magister Artium (Socio‐Informatics) © Stellenbosch University 2008 Supervisor: Prof Johann Kinghorn March 2008 Stellenbosch University http://scholar.sun.ac.za Declaration I, the undersigned, hereby declare that the work contained in this thesis is my own original work and that I have not previously in its entirety, or in part, at any university for a degree. Signature: ………………………………. Date: ………………………………. ii Stellenbosch University http://scholar.sun.ac.za Summary Open-source software is not something new; however, it has come into the spotlight in the last few years, mostly due to hyped initial cost savings of the Linux operating system. Consumers and businesses were made aware of shortcomings in the traditional proprietary software model and this has in turn created a surge in popularity of open-source. The migration to open-source requires efficient research of options available and thorough analysis of the migratory process through all levels of the organization. Initial independent cost analysis has not been conclusive, with unreliable, skewed results and below average performance due to poor implementation. The focus of this study is whether open-source software is a suitable alternative to current proprietary software packages utilized by the government sector. The government sector offers unique challenges to which open-source software can be ideally suited. These include high initial costs of hardware and proprietary software, vendor lock-in, file format “future proofing” and the need for high security. Open-source software has addressed most of these issues admirably, but requires proper implementation.

  • Web-Based Fingerprinting Techniques
    Web-based Fingerprinting Techniques V´ıtor Bernardo and Dulce Domingos LaSIGE, Faculdade de Ciencias,ˆ Universidade de Lisboa, Lisboa, Portugal Keywords: Browser Fingerprinting, Cross-browser Fingerprinting, Device Fingerprinting, Privacy, Fingerprint. Abstract: The concept of device fingerprinting is based in the assumption that each electronic device holds a unique set of physical and/or logical features that others can capture and use to differentiate it from the whole. Web-based fingerprinting, a particular case of device fingerprinting, allows website owners to differentiate devices based on the set of information that browsers transmit. Depending on the techniques being used, a website can track a device based on its browser features (browser fingerprinting) or based on system settings (cross-browser fingerprinting). The latter allows identification of the device even when more than one browser is used. Several different works have introduced new techniques over the last years proving that fingerprinting can be done in multiple ways, but there is not a consolidated work gathering all of them. The current work identifies known web-based fingerprinting techniques, categorizing them as which ones are browser and which are cross-browser and showing real examples of the data that can be captured with each technique. The study is synthesized in a taxonomy, which provides a clear separation between techniques, making it easier to identify the threats to security and privacy inherent to each one. 1 INTRODUCTION far more upsetting than simple cookies. In most cases, web-based fingerprinting is used to Device fingerprinting is based on the assumption that track users activity in sites and bind a device finger- no two devices are exactly alike and that profiles can print to a user profile (together with its preferences, be created by capturing the emanation patterns sent tastes and interests).
