- Description: The focus of the Fourth Industrial Revolution has been on its implications on Human Capital and its need to develop “21st-Century Skills" through education to ensure future labour and capital complementarity. Human Capital combined with 21st-Century Skills, it is claimed, can together generate economic growth, jobs and propel an economy into the next Industrial Revolution. However, Schwab’s (2016) concept of the Fourth Industrial Revolution, make no distinction between the Average Worker and the Knowledge Elite and their relationship to each other and successful economic growth. The different nature of these skills is absent in the literature to date. A critical analysis of literature will be used to examine Schwab’s (2016) claim of a Fourth Industrial Revolution and assess how the Average Worker and the Knowledge Elite relate to the Fourth Industrial Revolution and 21st-Century Skills. The evidence is provided on how both the Average Worker and the Knowledge Elite are key contributors to economic growth and will be important in the Fourth Industrial Revolution.

- Description: An HIV-positive diagnosis can be an overwhelming and traumatic experience. This study explores the experiences of receiving an HIV-positive diagnosis. Employing an Interpretative Phenomenological Analysis (IPA), a sample of the initial posts from threads on an online forum, was collected and explored, in order to determine the dominant themes from the experiences expressed in the posts, as well as the support sought from the forum. The online forum was accessed as an unobtrusive observer, and posts from January to December 2015 were explored. The online forum provides a platform for disclosure following an HIV-positive diagnosis, when anxiety and fear of stigma can impact on an individual’s ability to disclose to their social support network of family and friends. The experiences expressed on the online forum reflect the emotional, mental and physical impact of an HIV-positive diagnosis on an individual. The findings in this study reflected themes of shock, guilt and hopelessness, and concerns and fears regarding disclosure and stigma associated with HIV, as well as the importance of social support for the coping mechanisms of individuals after receiving an HIV-positive diagnosis. This research demonstrates the importance of Internet accessibility for information and support for chronic illnesses, such as HIV, and the role of the online forum platform for providing a safe environment for individuals recently diagnosed HIVpositive.

De-identification of personal information for use in software testing to ensure compliance with the Protection of Personal Information Act

- Description: Encryption of Personally Identifiable Information stored in a Structured Query Language Database has been difficult for a long time. This is owing to block-cipher encryption algorithms changing the length and type of the input data when encrypted, which cannot subsequently be stored in the database without altering its structure. As the enactment of the South African Protection of Personal Information Act, No 4 of 2013 (POPI), was set in motion with the appointment of the Information Regulators Office in December 2016, South African companies are intensely focused on implementing compliance strategies and processes. The legislation, promulgated in 2013, encompasses the processing and storage of personally identifiable information (PII), ensuring that corporations act responsibly when collecting, storing and using individuals’ personal data. The Act comprises eight broad conditions that will become legislation once the new Information Regulator’s office is fully equipped to carry out their duties. POPI requires that individuals’ data should be kept confidential from all but those who specifically have permission to access the data. This means that not all members of IT teams should have access to the data unless it has been de-identified. This study tests an implementation of the Fixed Feistel 1 algorithm from the National Institute of Standards and Technology (NIST) “Special Publication 800-38G: Recommendation for Block Cipher Modes of Operation : Methods for Format-Preserving Encryption” using the LibFFX Python library. The Python scripting language was used for the experiments. The research shows that it is indeed possible to encrypt data in a Structured Query Language Database without changing the database schema using the new Format-Preserving encryption technique from NIST800-38G. Quality Assurance software testers can then run their full set of tests on the encrypted database. There is no reduction of encryption strength when using the FF1 encryption technique, compared to the underlying AES-128 encryption algorithm. It further shows that the utility of the data is not lost once it is encrypted.

Designing and prototyping WebRTC and IMS integration using open source tools

- Description: WebRTC, or Web Real-time Communications, is a collection of web standards that detail the mechanisms, architectures and protocols that work together to deliver real-time multimedia services to the web browser. It represents a significant shift from the historical approach of using browser plugins, which over time, have proven cumbersome and problematic. Furthermore, it adopts various Internet standards in areas such as identity management, peer-to-peer connectivity, data exchange and media encoding, to provide a system that is truly open and interoperable. Given that WebRTC enables the delivery of multimedia content to any Internet Protocol (IP)-enabled device capable of hosting a web browser, this technology could potentially be used and deployed over millions of smartphones, tablets and personal computers worldwide. This service and device convergence remains an important goal of telecommunication network operators who seek to enable it through a converged network that is based on the IP Multimedia Subsystem (IMS). IMS is an IP-based subsystem that sits at the core of a modern telecommunication network and acts as the main routing substrate for media services and applications such as those that WebRTC realises. The combination of WebRTC and IMS represents an attractive coupling, and as such, a protracted investigation could help to answer important questions around the technical challenges that are involved in their integration, and the merits of various design alternatives that present themselves. This thesis is the result of such an investigation and culminates in the presentation of a detailed architectural model that is validated with a prototypical implementation in an open source testbed. The model is built on six requirements which emerge from an analysis of the literature, including previous interventions in IMS networks and a key technical report on design alternatives. Furthermore, this thesis argues that the client architecture requires support for web-oriented signalling, identity and call handling techniques leading to a potential for IMS networks to natively support these techniques as operator networks continue to grow and develop. The proposed model advocates the use of SIP over WebSockets for signalling and DTLS-SRTP for media to enable one-to-one communication and can be extended through additional functions resulting in a modular architecture. The model was implemented using open source tools which were assembled to create an experimental network testbed, and tests were conducted demonstrating successful cross domain communications under various conditions. The thesis has a strong focus on enabling ordinary software developers to assemble a prototypical network such as the one that was assembled and aims to enable experimentation in application use cases for integrated environments.
