Many system security departments treat users as a security risk to be controlled. The general consensus is that most users are careless and unmotivated when it comes to system security. In a recent study, we found that users may indeed compromise computer security mechanisms, such as password authentication, both knowing and unknowingly. A closer analysis,(More)
Global multimedia communications is advancing the freedom of information and knowledge. However, as the amount and variety of multimedia data generated through these applications increases, so do risks associated with widespread accessibility and utilization of such data. Specifically, data may be used in a manner which users regard as an invasion of their(More)
Perceived infringements of privacy can cause breakdowns in technologically mediated interactions, leading to user rejection of the technology. This research aims to identify the impact that users' perception of privacy has on their attitudes to, and behavior within, multimedia communication environments. Using both qualitative and quantitative data from(More)
To date, system research has focused on designing security mechanisms to protect systems access although their usability has rarely been investigated. This paper reports a study in which users’ perceptions of password mechanisms were investigated through questionnaires and interviews. Analysis of the questionnaires shows that many users report problems,(More)
The temporal elements of users' information requirements are a continually confounding aspect of digital library design. No sooner have users' needs been identified and supported than they change. This paper evaluates the changing information requirements of users through their 'information journey' in two different domains (health and academia). In-depth(More)
Many users are not aware of the potential privacy implications of ubiquitous multimedia applications. Decision-makers are often reluctant to raise users’ awareness, since this may open a “can of worms” and deter potential users. We conducted an opportunistic study after videoconferencing developers placed a camera in the common room of their university(More)
When ubiquitous multimedia technology is introduced in an organization, the privacy implications of that technology are rarely addressed. Users usually extend the trust they have in an organization to the technology it employs. This paper reports results from interviews with 24 Internet Engineering Task Force (IETF) attendees whose presentations or(More)
The social and organisational aspects of digital libraries (DLs) are often overlooked, but this paper reviews how they can affect users’ awareness and acceptance of DLs. An analysis of research conducted within two contrasting domains (clinical and academic) is presented which highlights issues of user interactions, work practices and organisational social(More)
