While explication of socio-technical challenges posed by personal data leverage in media research has been of interest recently, effective responses that alleviate them are yet to be studied. This paper reports the use of a Cross Media Profiler prototype supported by a Personal Data Store, that combines personal data from different media services for more holistic media recommendations. This prototype is used to probe and explore the integration of Human Data Interaction principles in media experiences, as a response to these challenges. Our focus groups reveal that users prefer the media service when supported by the PDS while highlighting improvements around transparency and control. The work leads to two outcomes : design recommendations for future media experiences to embody increased sensitivity to the implications of personal data leverage and a critique of the HDI agenda through the lens of data driven media, which scopes out potential for future IMX intervention.

This paper analyses the assumptions underpinning a range of emerging EU and UK smart home cybersecurity standards. We use internet of things (IoT) case studies (such as the Mirai Botnet affair) and the criminological concept of ‘routine activity theory’ to situate our critique. Our study shows that current cybersecurity standards mainly assume smart home environments are (and will continue to be) underpinned by cloud architectures. This is a shortcoming in the longevity of standards. This paper argues that edge computing approaches, such as personal information management systems , are emerging for the IoT and challenge the cloud focused assumptions of these standards. In edge computing, data can be stored in a decentralised manner, locally and analysed on the client using federated learning . This can have advantages for security, privacy and legal compliance, over centralised cloud-based approaches, particularly around cross border data flows and edge based security analytics . As a consequence, standards should start to reflect the increased interest in this trend to make them more aspirational and responsive for the long term; as ultimately, current IoT architectures are a choice, as opposed to inherent. Our paper unpacks the importance of the adoption of edge computing models which could enable better management of external cyber-criminality threats in smart homes. We also briefly discuss challenges of building smart homes that can accommodate the complex nature of everyday life in the home. In addition to technical aspects, the social and interactional complexities of the home mean internal threats can also emerge. As these human factors remain unresolved in current approaches to smart home cybersecurity, a user's security can be impacted by such technical design choices.

As more and more devices are connected to the Internet-of-Things, often made by non-specialist companies or short-lived startups, the likelihood that these devices will be hacked and used for nefarious activity online increases. We seek to support non-expert users in managing the network behaviour of their IoT devices, and assisting them in handling the cases where those devices are hacked. To do so, we wish to enable anomaly detection at the network level, determining when a device starts behaving unusually. This requires capturing data about how devices behave in a diverse range of real deployments, not just lab environments.

Security incidents such as targeted distributed denial of service (DDoS) attacks on power grids and hacking of factory industrial control systems (ICS) are on the increase. This paper unpacks where emerging security risks lie for the industrial internet of things, drawing on both technical and regulatory perspectives. Legal changes are being ushered by the European Union (EU) Network and Information Security (NIS) Directive 2016 and the General Data Protection Regulation 2016 (GDPR) (both to be enforced from May 2018). We use the case study of the emergent smart energy supply chain to frame, scope out and consolidate the breadth of security concerns at play, and the regulatory responses. We argue the industrial IoT brings four security concerns to the fore, namely: appreciating the shift from offline to online infrastructure; managing temporal dimensions of security; addressing the implementation gap for best practice; and engaging with infrastructural complexity. Our goal is to surface risks and foster dialogue to avoid the emergence of an Internet of Insecure Industrial Things.

Bringing the new right to data portability (RTDP) from an abstract legal provision in Article 20 of the EU General Data Protection Regulation (GDPR) 2016 into practice requires a greater role for the IT design community. Simply put, the RTDP seeks to empower users by giving them greater control over their personal data, enabling them to both acquire their data and then move it around, for example to a different data controller. In this paper, we focus on how IT designers can use Privacy by Design (PbD) approaches to respond to these RTDP obligations. We are particularly interested in how the RTDP plays out for the technological context of the domestic Internet of things (IoT). By examining the legal, commercial and technical landscape around the RTDP, we can begin to unpack the practical roadblocks and opportunities ahead in implementing the right in practice.

Creating and utilizing simple links between items and locations in map-based systems has become a mainstream component of modern computing. In this paper, we explore support for "art mapping", an activity that requires consideration of more complex interpretations of spatial relationships as users engage with identifying locations of relevance to artworks. Through a user study of the ArtMaps platform, and an exploratory study with professional artists, we identify diverse interpretations of spatial meaning in relation to art. We find that art mapping highlights potential for more active engagement with art through technology, but challenges existing systems for spatial representation. Through connecting our findings with work on designing for interpretation, and on space and place in HCI, we contribute new understanding of creating engagement through the spatial interpretation of art, and define potential characteristics and uses of holistic "footprints" for artworks.

In this paper we argue for the position that responsible safeguards for privacy and ethical treatment of human data are of vital importance to retain the public confidence and trust that is necessary for the development and future success of internet mediated research (IMR). We support our position based on the high level of popular and media attention that is currently directed at IMR, which in combination with the relative uncertainties that still exist around the ethics of various IMR methods, raises the risk that IMR might succumb to a public backlash of similar proportions to the controversy that hit genetically modified (GM) crops in Europe. Based on the lessons that came out of the GM crops controversy we discuss the ethics requirements and challenges that must be met in order to retain the public trust in IMR. We end our argument by briefly reviewing a couple of examples of “privacy protecting architectures” that are being developed for IMR.

The Creativity Bento Box is a physical resource pack, designed to support casual social interaction and break taking in an intensive, computer-mediated social activity. It was developed within the Creativity Greenhouse project, which piloted a mechanism to create research proposals and distribute funding at a distance. This involved facilitated phases of collaboration and competition over multiple days of computer-mediated work, where participants communicate and interact through a virtual world. During the iterative development process, the lack of time for socializing, the intense focus on virtual resources, and a lack of time spent away from the screen were reported as negative issues in feedback from participants. This article reports on the development of the Creativity Bento Box and how it helped to address these issues. By providing physical resources that contrasted with the properties of the virtual world, it supported people to socialize and take breaks from their primary activity, allowed them to include physical space and artifacts in their interactions, and provoked moves away from the otherwise intense focus on the computer. The article reflects on the roles of the Bento Box as a gift, in bridging between physical and virtual contexts, its higher suitability during the earlier phases of ideation and group development, and its perception by participants as something “framed.” Through this, we highlight the underexplored potential of using physical, offline resources as a means to solve difficulties in distanced social interactions.

Current anonymity techniques for mobile opportunistic networks typically use obfuscation algorithms to hide node's identity behind other nodes. These algorithms are not well suited to sparse and disconnection prone networks with large number of malicious nodes and new opportunistic, adaptive. So, new, opportunistic, adaptive fully localized mechanisms are needed for improving user anonymity. This paper proposes reputation aware localized adaptive obfuscation for mobile opportunistic networks that comprises of two complementary techniques: opportunistic collaborative testing of nodes' obfuscation behaviour (OCOT) and multidimensional adaptive anonymisation (AA). OCOT-AA is driven by both explicit and implicit reputation building, complex graph connectivity analytics and obfuscation history analyses. We show that OCOT-AA is very efficient in terms of achieving high levels of node identity obfuscation and managing low delays for answering queries between sources and destinations while enabling fast detection and avoidance of malicious nodes typically within the fraction of time within the experiment duration. We perform extensive experiments to compare OCOT-AA with several other competitive and benchmark protocols and show that it outperforms them across a range of metrics over a one month real-life GPS trace. To demonstrate our proposal more clearly, we propose new metrics that include best effort biggest length and diversity of the obfuscation paths, the actual percentage of truly anonymised sources' IDs at the destinations and communication quality of service between source and destination.

Ubiquitous and pervasive computing techniques have been used to inform discourses around climate change and energy insecurity, traditionally through data capture and representation for scientists, policy makers and the public. Research into re-engaging the public with sustainability and climate change issues reveals the significance of emotional and personal engagement alongside locally meaningful, globally-relevant and data-informed climate messaging for the public. New ubiquitous and pervasive computing techniques are emerging to support the next generation of climate change stakeholders, including artists, community practitioners, educators and data hackers, to create scientific data responsive artworks and performances. Grounded in our experiences of community based artistic interventions, we explore the design and deployments of the Timestreams platform, demonstrating usages of ubiquitous and pervasive computing within these new forms of discourse around climate change and energy insecurity.

Automics is a photo-souvenir service which utilises mobile devices to support the capture, sharing and annotation of digital images amongst groups of visitors to theme parks. The prototype service mixes individual and group photo-capture with existing in-park, on-ride photo services, to allow users to create printed photo-stories. Herein we discuss initial fieldwork in theme parks that grounded the design of Automics, our development of the service prototype, and its real-world evaluation with theme park visitors. We relate our findings on user experience of the service to a literature on mobile photoware, finding implications for the design of souvenir services.

Emerging robotic technologies are enabling the control of individual seats on rollercoasters and other thrill rides. We explore the potential of breathing as an effective and engaging way of driving this. Observations and interviews from trials of an enhanced bucking bronco ride show that breath-control is fun, challenging and intelligible, and reveal riders-x tactics as they battled the machine. We conclude that breath control is feasible and appropriate for controlling rides, unpack its important characteristics, and consider how it might be built into future ride systems. We argue that the combination of voluntary and involuntary factors in breathing is especially appealing for controlling rides as it balances game-like elements of skill and learning against the thrill of surrendering control to the machine.

In this paper, we argue that, with an appropriate operating system structure, energy in mobile computers can be treated and managed as just another resource. In particular, we investigate how energy management could be added to the Nemesis OS which provides detailed and accurate resource accounting capabilities in order to provide Quality of Service (QoS) guarantees for all resources to applications. We argue that, with such an operating system, accounting of energy to individual processes can be achieved. Furthermore, we investigate how an economic model, proposed for congestion avoidance in computer network, and recently applied to CPU resource management, can be used as a dynamic, decentralised energy management system, forming a collaborative environment between operating system and applications.

Dynamic reconfiguration of FPGAs is a powerful technique for modifying a circuit as it executes. However, dynamic reconfiguration is inadequately supported by CAD tools and poorly understood in general. We present a specific class of dynamic reconfigurations that can be expressed in terms of a formalism called partial evaluation. This provides a systematic framework for understanding the effect of a dynamic reconfiguration, as well as providing guidance on how to complete specialised circuits. The primary advantages of this technique are circuits which are smaller and faster for a certain class of applications. We present one case study from the ATM field which benefits from this treatment.

Support for multimedia applications by general purpose computing platforms has been the subject of considerable research. Much of this work is based on an evolutionary strategy in which small changes to existing systems are made. The approach adopted is to start ab initio with no backward compatibility constraints. This leads to a novel structure for an operating system. The structure aims to decouple applications from one another and to provide multiplexing of all resources, not just the CPU, at a low level. The motivation for this structure, a design based on the structure, and its implementation on a number of hardware platforms is described.

The desk area network was proposed as an architecture suitable for a multimedia workstation. This paper describes how the architecture has evolved and the demonstration workstation that has been constructed.>
