  • Bluetooth command and control channel 
    Pieterse, Heloise; Olivier, Martin S. (Elsevier, 2014-09)
    Bluetooth is popular technology for short-range communications and is incorporated in mobile devices such as smartphones, tablet computers and laptops. Vulnerabilities associated with Bluetooth technology led to improved ...
  • A comparison of simulated traffic conditioner performance 
    Strauss, Tinus; Kourie, Derrick G.; Olivier, Martin S. (Elsevier, 2008-11)
    In this paper, the simulated performance of a number of differentiated services traffic conditioners is studied under a range of synthetic traffic conditions. The traffic conditioners are compared using two performance ...
  • Database application schema forensics 
    Beyers, Hector Quintus; Olivier, Martin S.; Hancke, Gerhard P. (Computer Society of South Africa, 2014-12)
    The application schema layer of a Database Management System (DBMS) can be modi ed to produce results that do not re ect the data actually stored in the database. For example, table structures may be corrupted by changing ...
  • Design of a hybrid command and control mobile botnet 
    Pieterse, Heloise; Olivier, Martin S. (Journal of Information Warfare, 2013)
    The increasing popularity and improvement in capabilities offered by smartphones caught the attention of botnet developers. Now the threat of botnets is moving towards the mobile environment. This study presents the design ...
  • Detecting manipulated smartphone data on Android and iOS devices 
    Pieterse, Heloise; Olivier, Martin S.; Van Heerden, Renier (Springer, 2019-01-25)
    Ever improving technology allows smartphones to become an integral part of people’s lives. The reliance on and ubiquitous use of smartphones render these devices rich sources of data. This data becomes increasingly important ...
  • Digital forensic science : a manifesto 
    Olivier, Martin S. (Computer Society of South Africa, 2016-12)
    Most members of the public probably had a rather vague notion of forensic science until various TV shows — starting with CSI — carried an image of a forensic utopia into our living rooms on a weekly basis. In general we ...
  • Digital forensics and the big data deluge — some concerns based on Ramsey theory 
    Olivier, Martin S. (Springer, 2020-08)
    Constructions of science that slowly change over time are deemed to be the basis of the reliability with which scientific knowledge is regarded. A potential paradigm shift based on big data is looming – many researchers ...
  • A fraud management system architecture for next-generation networks 
    Bihina Bella, M.A. (Madeleine Adrienne); Eloff, Jan H.P.; Olivier, Martin S. (Elsevier, 2009)
    This paper proposes an original architecture for a fraud management system (FMS) for convergent. Nextgeneration networks (NGNs), which are based on the Internet protocol (IP). The architecture has the potential to satisfy ...
  • The impact of triggers on forensic acquisition and analysis of databases 
    Hauger, W.K. (Werner); Olivier, Martin S. (South African Institute of Electrical Engineers, 2015-06)
    An aspect of database forensics that has not received much attention in the academic research community yet is the presence of database triggers. Database triggers and their implementations have not yet been thoroughly ...
  • NoSQL databases : forensic attribution implications 
    Hauger, W.K. (Werner); Olivier, Martin S. (South African Institute of Electrical Engineers, 2018-06)
    NoSQL databases have gained a lot of popularity over the last few years. They are now used in many new system implementations that work with vast amounts of data. Such data will typically also include sensitive information ...
  • On compound purposes and compound reasons for enabling privacy 
    Van Staden, W.J.S. (Wynand Johannes Christiaan); Olivier, Martin S. (Graz University of Technology, 2011-02-01)
    This paper puts forward a verification method for compound purposes and compound reasons to be used during purpose limitation. When it is absolutely necessary to collect privacy related information, it is essential ...
  • Reference architecture for android applications to support the detection of manipulated evidence 
    Pieterse, H.; Olivier, Martin S.; Van Heerden, R.P. (South African Institute of Electrical Engineers, 2016-06)
    Traces found on Android smartphones form a significant part of digital investigations. A key component of these traces is the date and time, often formed as timestamps. These timestamps allow the examiner to relate the ...
  • “Siel van die mier” : reflections on the battle for ‘scholarly’ intelligence 
    Olivier, Martin S. (Vaal Triangle Faculty of Northwest University in South Africa, 2015-11)
    This essay traces two research programmes in broad strokes. Both programmes start from the same observation — the behaviour of an ant (or termite) colony and the ability of the ant colony to act in a collective manner ...
  • Smartphone data evaluation model : identifying authentic smartphone data 
    Pieterse, Heloise; Olivier, Martin S.; Van Heerden, Renier (Elsevier, 2018-03)
    Ever improving smartphone technology, along with the widespread use of the devices to accomplish daily tasks, leads to the collection of rich sources of smartphone data. Smartphone data are, however, susceptible to change ...
