mSpace meets EPrints: a Case Study in Creating Dynamic Digital Collections

In this case study we look at issues involved in (a) generating dynamic digital libraries that are on a particular topic but span heterogeneous collections at distinct sites, (b) supplementing the artefacts in that collection with additional information available either from databases at the artefact's home or from the Web at large, and (c) providing an interaction paradigm that will support effective exploration of this new resource. We describe how we used two available frameworks, mSpace and EPrints to support this kind of collection building. The result of the study is a set of recommendations to improve the connectivity of remote resources both to one another and to related Web resources, and that will also reduce problems like co-referencing in order to enable the creation of new collections on demand

Second-Level Digital Divide: Mapping Differences in People's Online Skills

Much of the existing approach to the digital divide suffers from an important limitation. It is based on a binary classification of Internet use by only considering whether someone is or is not an Internet user. To remedy this shortcoming, this project looks at the differences in people's level of skill with respect to finding information online. Findings suggest that people search for content in a myriad of ways and there is a large variance in how long people take to find various types of information online. Data are collected to see how user demographics, users' social support networks, people's experience with the medium, and their autonomy of use influence their level of user sophistication.Comment: 29th TPRC Conference, 200

Online Child Sex Solicitation: Exploring the Feasibility of a Research 'Sting'

A small scale test of the integrity of Internet Web 2.0 social network sites was undertaken over several weeks in 2007. The fictional identities of four female underage children where posted on three network sites and later introduced to relay chat forums in order to explore the impact of apparent vulnerability on potential selection of Internet victims. Only one of the three social network sites in the study recognised that the postings violated child protection policies and subsequently closed down the underage postings. Two basic identities were created: one that engendered a needy and vulnerable characterisation of a child while the other identity was created to represent a happy and attached child character. The number of contacts and suspicious contacts were monitored to test assumptions about child ‘vulnerability’ and risks of unwanted sexual solicitations. The characters created also included either an avatar and/or contact details. These variants of the experiment showed that the inclusion of an image or access details increased the likelihood of contacts, including suspicious contact regardless of ‘vulnerability’. This small experiment noted that although vulnerable children with additional cues maybe at more risk all children who posted details about themselves on social network sites faced the risk of contact by predators. The need for further research and better means of regulating such sites was suggested

XML content warehousing: Improving sociological studies of mailing lists and web data

In this paper, we present the guidelines for an XML-based approach for the sociological study of Web data such as the analysis of mailing lists or databases available online. The use of an XML warehouse is a flexible solution for storing and processing this kind of data. We propose an implemented solution and show possible applications with our case study of profiles of experts involved in W3C standard-setting activity. We illustrate the sociological use of semi-structured databases by presenting our XML Schema for mailing-list warehousing. An XML Schema allows many adjunctions or crossings of data sources, without modifying existing data sets, while allowing possible structural evolution. We also show that the existence of hidden data implies increased complexity for traditional SQL users. XML content warehousing allows altogether exhaustive warehousing and recursive queries through contents, with far less dependence on the initial storage. We finally present the possibility of exporting the data stored in the warehouse to commonly-used advanced software devoted to sociological analysis

Towards memory supporting personal information management tools

In this article we discuss re-retrieving personal information objects and relate the task to recovering from lapse(s) in memory. We propose that fundamentally it is lapses in memory that impede users from successfully re-finding the information they need. Our hypothesis is that by learning more about memory lapses in non-computing contexts and how people cope and recover from these lapses, we can better inform the design of PIM tools and improve the user's ability to re-access and re-use objects. We describe a diary study that investigates the everyday memory problems of 25 people from a wide range of backgrounds. Based on the findings, we present a series of principles that we hypothesize will improve the design of personal information management tools. This hypothesis is validated by an evaluation of a tool for managing personal photographs, which was designed with respect to our findings. The evaluation suggests that users' performance when re-finding objects can be improved by building personal information management tools to support characteristics of human memory

Refining the PoinTER “human firewall” pentesting framework

PurposePenetration tests have become a valuable tool in the cyber security defence strategy, in terms of detecting vulnerabilities. Although penetration testing has traditionally focused on technical aspects, the field has started to realise the importance of the human in the organisation, and the need to ensure that humans are resistant to cyber-attacks. To achieve this, some organisations “pentest” their employees, testing their resilience and ability to detect and repel human-targeted attacks. In a previous paper we reported on PoinTER (Prepare TEst Remediate), a human pentesting framework, tailored to the needs of SMEs. In this paper, we propose improvements to refine our framework. The improvements are based on a derived set of ethical principles that have been subjected to ethical scrutiny.MethodologyWe conducted a systematic literature review of academic research, a review of actual hacker techniques, industry recommendations and official body advice related to social engineering techniques. To meet our requirements to have an ethical human pentesting framework, we compiled a list of ethical principles from the research literature which we used to filter out techniques deemed unethical.FindingsDrawing on social engineering techniques from academic research, reported by the hacker community, industry recommendations and official body advice and subjecting each technique to ethical inspection, using a comprehensive list of ethical principles, we propose the refined GDPR compliant and privacy respecting PoinTER Framework. The list of ethical principles, we suggest, could also inform ethical technical pentests.OriginalityPrevious work has considered penetration testing humans, but few have produced a comprehensive framework such as PoinTER. PoinTER has been rigorously derived from multiple sources and ethically scrutinised through inspection, using a comprehensive list of ethical principles derived from the research literature

Fourth Amendment Fiduciaries

Fourth Amendment law is sorely in need of reform. To paraphrase Justice Sotomayor’s concurrence in United States v. Jones, the idea that people have no expectation of privacy in information voluntarily shared with third-parties—the foundation of the widely reviled “third-party doctrine”—makes little sense in the digital age. In truth, however, it is not just the third-party doctrine that needs retooling today. It is the Fourth Amendment’s general approach to the problem of “shared information.” Under existing law, if A shares information with B, A runs the risk of “misplaced trust”—the risk that B will disclose the information to law enforcement. Although the misplaced trust rule makes sense as a default, it comes under strain in cases where A and B have no relationship of trust and the only reason that A shares information with B is to obtain a socially valuable (and practically indispensable) service. In such cases, I argue that the doctrine should treat B as an “information fiduciary” and analyze B’s cooperation with law enforcement—whether voluntary or compelled—as a Fourth Amendment search. The argument develops in three parts. Part I demonstrates that the Court has already identified two settings—if only implicitly—where fiduciary-style protections are necessary to safeguard constitutional privacy: medical care and hotels. When A is a patient and B is a doctor, and, likewise, when A is a guest and B is a hotel manager, the Court has been reluctant to apply the “misplaced trust” rule. Rightly so: the principle is mismatched to the underlying relationship. From there, Part II fleshes out the normative argument. Put simply, we do not “trust” information fiduciaries, in the everyday sense, at all. So it makes little sense—normatively, or even semantically—to speak of trust being “misplaced.” Rather, the information is held for the benefit of the sharing party, and its use should be constrained by implied duties of care and loyalty. Finally, Part III lays the groundwork for determining who are “Fourth Amendment fiduciaries.” The Article concludes by exploring various practical metrics that courts might adopt to answer this question

Information access tasks and evaluation for personal lifelogs

Emerging personal lifelog (PL) collections contain permanent digital records of information associated with individuals’ daily lives. This can include materials such as emails received and sent, web content and other documents with which they have interacted, photographs, videos and music experienced passively or created, logs of phone calls and text messages, and also personal and contextual data such as location (e.g. via GPS sensors), persons and objects present (e.g. via Bluetooth) and physiological state (e.g. via biometric sensors). PLs can be collected by individuals over very extended periods, potentially running to many years. Such archives have many potential applications including helping individuals recover partial forgotten information, sharing experiences with friends or family, telling the story of one’s life, clinical applications for the memory impaired, and fundamental psychological investigations of memory. The Centre for Digital Video Processing (CDVP) at Dublin City University is currently engaged in the collection and exploration of applications of large PLs. We are collecting rich archives of daily life including textual and visual materials, and contextual context data. An important part of this work is to consider how the effectiveness of our ideas can be measured in terms of metrics and experimental design. While these studies have considerable similarity with traditional evaluation activities in areas such as information retrieval and summarization, the characteristics of PLs mean that new challenges and questions emerge. We are currently exploring the issues through a series of pilot studies and questionnaires. Our initial results indicate that there are many research questions to be explored and that the relationships between personal memory, context and content for these tasks is complex and fascinating

We Could, but Should We? Ethical Considerations for Providing Access to GeoCities and Other Historical Digital Collections

We live in an era in which the ways that we can make sense of our past are evolving as more artifacts from that past become digital. At the same time, the responsibilities of traditional gatekeepers who have negotiated the ethics of historical data collection and use, such as librarians and archivists, are increasingly being sidelined by the system builders who decide whether and how to provide access to historical digital collections, often without sufficient reflection on the ethical issues at hand. It is our aim to better prepare system builders to grapple with these issues. This paper focuses discussions around one such digital collection from the dawn of the web, asking what sorts of analyses can and should be conducted on archival copies of the GeoCities web hosting platform that dates to 1994.This research was supported by the Natural Sciences and Engineering Research Council of Canada, the Social Sciences and Humanities Research Council of Canada, the US National Science Foundation (grants 1618695 and 1704369), the Andrew W.
