  • Touch Biometrics for Unobtrusive Continuous Authentication on Smartphones 
    Kroeze, Christina J. (University of Pretoria, 2015)
    Mobile devices such as smartphones have until now been protected by traditional authentication methods, including passwords or PINs. These authentication mechanisms are di cult to remember and often disabled, leaving the ...
  • Using depth information to aid stereoscopic image forensics 
    Fouche, Mark-Anthony (University of Pretoria, 2014)
    With the advances in image manipulation software, it has become easier to manipulate digital images. These manipulations can be used to increase image quality, but can also be used to depict a scene that never occurred. ...
  • Digital Audio Restoration of Gramophone Records 
    Stallmann, Christoph Frank (University of Pretoria, 2015)
    Gramophones were the main audio recording medium for more than seven decades and regained widespread popularity over the past few years. Being an analogue storage medium, gramophone records are subject to distortions caused ...
  • Digital Forensics in Second Life 
    Rakitianskaia, A.S. (Anastassia Sergeevna) (University of Pretoria, 2015)
    Computers and the internet have become an integral part of our lives. People have grown accustomed to feeling constantly connected to the outside world, and in the past couple of decades online social networks and ...
  • A Computational Intelligence Approach to Clustering of Temporal Data 
    Georgieva, Kristina Slavomirova (University of Pretoria, 2015)
    Temporal data is common in real-world datasets. Analysis of such data, for example by means of clustering algorithms, can be difficult due to its dynamic behaviour. There are various types of changes that may occur to ...
  • Reconstruction in Database Forensics 
    Adedayo, Oluwasola Mary (University of Pretoria, 2015)
    The increasing usage of databases in the storage of critical and sensitive information in many organizations has led to an increase in the rate at which databases are exploited in computer crimes. Databases are often ...
  • Design of a hybrid command and control mobile botnet 
    Pieterse, Heloise (University of Pretoria, 2014)
    Mobile devices have excelled in the 21st century due to the increasing popularity and continuous improvement of mobile technology. Today mobile devices have become all-in-one portable devices, providing inter-connectivity, ...
  • Automated usability analysis and visualisation of eye tracking data 
    De Bruin, Jhani Adre (University of Pretoria, 2014)
    Usability is a critical aspect of the success of any application. It can be the deciding factor for which an application is chosen and can have a dramatic effect on the productivity of users. Eye tracking has been ...
  • An investigation into the consistency and usability of selected minisatellite detecting software packages 
    Masombuka, Koos Themba (University of Pretoria, 2013)
    A tandem repeat is a sequence of adjacent repetitions of a nucleotide patternsignature, called its motif, in a DNA sequence. The repetitions may either be exact or approximate copies of the motif. A minisatellite is a ...
  • A Chain of findings for digital investigations 
    De Souza, Pedro (University of Pretoria, 2013)
    Digital Forensic investigations play a vital role in our technologically enhanced world, and it may incorporate a number of different types of evidence — ranging from digital to physical. During a Digital Forensics ...
  • Characterising continuous optimisation problems for particle swarm optimisation performance prediction 
    Malan, Katherine Mary (University of Pretoria, 2014)
    Real-world optimisation problems are often very complex. Population-based metaheuristics, such as evolutionary algorithms and particle swarm optimisation (PSO) algorithms, have been successful in solving many of these ...
  • A graph-based framework for comparing curricula 
    Marshall, Linda (University of Pretoria, 2014)
    The problem addressed in this thesis was identified in a real life context in which an attempt was made to re-constitute a BSc Computer Science degree programme. The curriculum was modelled on the ACM/IEEE Computing ...
  • Implementing a reusable design pattern Library in C# 
    Van Leeuwen, Alastair (University of Pretoria, 2013)
    Design patterns in software systems are described as a universal reusable solution to a commonly recurring problem in software design. Design patterns were, however, not intended to be reusable in terms of code. A symptom ...
  • Spamming mobile botnet detection using computational intelligence 
    Vural, Ickin (University of Pretoria, 2013)
    This dissertation explores a new challenge to digital systems posed by the adaptation of mobile devices and proposes a countermeasure to secure systems against threats to this new digital ecosystem. The study provides ...
  • Forensic evidence isolation in clouds 
    Delport, Waldo (University of Pretoria, 2013)
    Cloud computing is gaining acceptance and also increasing in popularity. Organisations often rely on cloud resources as an effective replacement for their `in-house' computer systems. In the cloud, virtual resources are ...
  • Finding digital forensic evidence when graphic design applications are used for document counterfeiting 
    Mabuto, Enos Kudakwashe (University of Pretoria, 2013)
    Graphic design applications are often used for the editing and design of digital art. The same applications can be used for creating counterfeit documents such as identity documents (IDs), driver’s licenses or passports, ...
  • A Generalized theoretical deterministic particle swarm model 
    Cleghorn, Christopher Wesley (University of Pretoria, 2013)
    Particle swarm optimization (PSO) is a well known population-based search algorithm, originally developed by Kennedy and Eberhart in 1995. The PSO has been utilized in a variety of application domains, providing a wealth ...
  • Assessing quality in software engineering : a pragmatic approach 
    Acton, Daniel (University of Pretoria, 2013)
    As long as software has been produced, there have been efforts to strive for quality in software products. In order to understand quality in software products, researchers have built models of software quality that rely ...
  • Coevolution of Neuro-controllers to Train Multi-Agent Teams from Zero Knowledge 
    Scheepers, Christiaan (University of Pretoria, 2013)
    After the historic chess match between Deep Blue and Garry Kasparov, many researchers considered the game of chess solved and moved on to the more complex game of soccer. Artificial intelligence research has shifted focus ...
