In this thesis, a novel secure SMS banking protocol based on steganography is proposed. The steganographic system proposed is based on a multi-channel security protocol that combines steganography by cover synthesis and steganography by cover modification. The resulting protocol takes into account the mobile characteristics and constraints, delivering confidentiality based on steganography with covert multiple channels but avoiding the need for hardware devices creating symmetric session keys as in traditional cryptographic solutions. The design is also done in such a way that it makes the protocol robust against various types o attacks. Furthermore, this thesis describes a novel theoretical framework for models that applies the concept of game theory in an entropy-based steganographic protocol setting. This framework includes the design of use cases and it is then used to evaluate the entropy-based steganographic protocol.
Mr Obinna Omego is currently pursuing a PhD in computer science at Kingston University where he dedicates most of his time developing security controls in the area of multichannel steganographic protocols to mitigate the risks in Mobile Banking. He has published three peer-reviewed IEEE international conference papers within the area of SMS based Mobile Banking and Steganography.
In 2015, Mr Obinna Omego was employed as an assistant lecturer at Madonna University, Rivers State Nigeria. His working experience enabled him to supervise 9 BSc Computer Science dissertations. As an Industrial training coordinator, he has monitored and supervised Industrial Training students in their various areas of placements. His lecturing experience in academic subjects includes Introduction to Information Security and Compiler Construction.
