- Description: In this paper, we present the design and implementation of a NPU-CPU heterogeneous network monitoring application. This application allows for both filtering and monitoring operations to be performed on network traffic based on country of origin or destination of IP traffic in real-time at wire speeds up to 1 Gbit/s. This is achievable by distributing the application components to the relevant candidate architectures, leveraging the strengths of each. Communication between architectures is handled at runtime by a low latency synchronous message passing library. Testing of the implemented application indicates that the system can perform geolocation lookups on network traffic in real-time without impacting network throughput.

- Description: Currently, network analytics requires direct access to network packets, normally through a third-party application, which means that obtaining realtime results is difficult. We propose the NFP-CPU heterogeneous framework to allow parts of applications written in the Go programming language to be executed on a Network Flow Processor (NFP) for enhanced performance. This paper explores the need and feasibility of implementing a message passing model for data transmission between the NFP and CPU, which is the crux of such a heterogeneous framework. Architectural differences between the two domains are highlighted within this context and we present a solution to bridging these differences.

- Description: In the new Digital Economy, mobile devices are increasingly being used for tasks that involve sensitive and/or f inancial data. Hitherto, security on smartphones has not been a priority and furthermore, users tend to ignore the security features in favour of more rapid access to the device. We propose an authentication system that can provide enhanced security by utilizing multi-modal biometrics from a single image, captured at arm’s length, containing unique face and iris data. The system is compared to state-of-the-art face and iris recognition systems, in related studies using the CASIA-Iris-Distance dataset and the IITD iris dataset. The proposed system outperforms the related studies in all experiments and shows promising advancements to at-a-distance iris recognition on mobile devices.
