With the recent rise in popularity of wearable personal health monitoring devices, a number of concerns regarding user privacy are raised, specifically with regard to how the providers of these devices make use of the data obtained from these devices, and the protections that user data enjoys. With waterproof monitors intended to be worn 24 hours per day, and companion smartphone applications able to offer analysis and sharing of activity data, we investigate and compare the privacy policies of four services, and the extent to which these services protect user privacy, as we find these services do not fall within the scope of existing legislation regarding the privacy of health data. We then present a set of criteria which would preserve user privacy, and avoid the concerns identified within the policies of the services investigated.

Recently, Internet of Things (IoT) deployments have shown their potential for aiding the realisation of the Sustainable Development Goals (SDGs). Concerns regarding how the IoT can specifically drive SDGs 6, 11 and 9 in developing countries have been raised with respect to the challenges of deploying licensed and unlicensed low-power wide area network (LPWAN) IoT technologies and their opportunities for IoT consumers and service providers. With IoT infrastructure and protocols being ubiquitous and each being proposed for different SDGs, we review and compare the various performance characteristics of LoRaWAN and NB-IoT networks. From the performance analysis of our networks, NB-IoT, one of the standardised promising cellular IoT solutions for developing countries, is more expensive and less energy-efficient than LoRaWAN. Utilising the same user equipment (UE), NB-IoT consumed an excess of 2 mAh of power for joining the network and 1.7 mAh more for a 44-byte uplink message compared to LoRaWAN. However, NB-IoT has the advantage of reliably and securely delivering higher network connection capacity in IoT use cases, leveraging existing cellular infrastructure. With a maximum throughput of 264 bps at 837 ms measured latency, NB-IoT outperformed LoRaWAN and proved robust for machine-type communications. These findings will help IoT consumers and service providers understand the performance differences and deployment challenges of NB-IoT and LoRaWAN and establish new research directions to tackle IoT issues in developing countries. With Nigeria as a case study, for consumers and organisations at a crossroads in their long-term deployment decisions, the proposed LPWAN integrated architecture is an example of the deployment opportunities for consumer and industrial IoT applications in developing countries.

Despite the announcement of a ‘new trade strategy’, EU agricultural trade policy has exhibited considerable consistency over several decades, always conditional on the CAP regime and the course of its reform. A 25-year, heavily subsidised transition, will shortly see European farmers (thanks to income support of up to 50% of their total income), able to enter the world market without export subsidies. Meanwhile the EC expects ‘partner’ countries in Africa (and the Caribbean and the Pacific) with still underdeveloped infrastructures, and provided with relatively trivial subsidies, to complete a similar process in a decade or so. The economic partnership agreement (EPA) negotiations are based on a shift from the Lomé Convention's non-reciprocity commitment to a basic regime of free trade between the EU and EPA regions, involving liberalisation of trade in goods, trade-related areas and services. Whereas Europe has already effectively integrated, few African regions have yet got very far in regional integration, but the EC is forcing the pace in negotiations so that there is a risk that integration will be with the EU rather than within a country's own region, and on the EU's terms. A ‘development dimension’ adds an element of window-dressing (or sugaring of the pill). This article considers the development programmes that the EU is promising in order to address infrastructural constraints in the partner countries, and the costs of adjustment to free trade, in particular the loss of state revenues generated from tariffs. The article concludes with an attempt to foresee the likely outcomes and implications of the negotiations, including the undermining of government revenues and the consequent increase in reliance on the private sector for many services, accelerated deindustrialisation, and the inhibiting of first-stage processing of agricultural commodities, the undermining of regional integration, the economic ‘recolonisation’ of Africa and the harming of efforts to promote national exploitation of economic resources.

This paper investigates the practicality of memory attacks on commercial Graphics Processing Units (GPUs). With recent advances in the performance and viability of using GPUs for various highly-parallelised data processing tasks, a number of security challenges are raised. Unscrupulous software running subsequently on the same GPU, either by the same user, or another user, in a multiuser system, may be able to gain access to the contents of the GPU memory. This contains data from previous program executions. In certain use-cases, where the GPU is used to offload intensive parallel processing such as pattern matching for an intrusion detection system, financial systems, or cryptographic algorithms, it may be possible for the GPU memory to contain privileged data, which would ordinarily be inaccessible to an unprivileged application running on the host computer. With GPUs potentially yielding access to confidential information, existing research in the field is built upon, to investigate the practicality of extracting data from global, shared and texture memory, and retrieving this data for further analysis. These techniques are also implemented on various GPUs using three different Nvidia CUDA versions. A novel methodology for digital forensic examination of GPU memory for remanent data is then proposed, along with some suggestions and considerations towards countermeasures and anti-forensic techniques.
