Lifelogs and autonomy

Autonomy seems to be a core issue for lifelogging technology as it can influence our understanding as well as our personal freedom but a comprehensive discussion on the effect of it on the autonomy of the lifelogger and others affected seems still missing in the current academic debate. In this article we provide a preliminary inquiry into this topic. First, the concept of lifelogging will be briefly clarified. In a lifelog, different data sources are combined in an archive that can be used to retrieve information about the lifelogger and the environment in which the lifelogger is situated. Second, we will discuss the effect of lifelogs on an element of autonomy, namely understanding. Lifelogs can both advance understanding as well as hinder it. Information of lifelogs is the result of social processes that can bias information and can be used to manipulate lifeloggers. Third, we will discuss another aspect of autonomy, namely being free from controlling influences. Also on this level the effect of lifelogs is ambiguous. Fourth, we will discuss the conditions under which prospective lifelogger become lifeloggers. By discussing both the effect of lifelogs on autonomy as well as joining the community of lifeloggers we aim to show the many ways in which lifelogs can compromise and advance autonomy. Fifth, some recommendations are provided that aim to address the above mentioned concerns

Analysing privacy in visual lifelogging

The visual lifelogging activity enables a user, the lifelogger, to passively capture images from a first-person perspective and ultimately create a visual diary encoding every possible aspect of her life with unprecedented details. In recent years, it has gained popularities among different groups of users. However, the possibility of ubiquitous presence of lifelogging devices specifically in private spheres has raised serious concerns with respect to personal privacy. In this article, we have presented a thorough discussion of privacy with respect to visual lifelogging. We have re-adjusted the existing definition of lifelogging to reflect different aspects of privacy and introduced a first-ever privacy threat model identifying several threats with respect to visual lifelogging. We have also shown how the existing privacy guidelines and approaches are inadequate to mitigate the identified threats. Finally, we have outlined a set of requirements and guidelines that can be used to mitigate the identified threats while designing and developing a privacy-preserving framework for visual lifelogging

Challenges and opportunities of lifelog technologies: a literature review and critical analysis

In a lifelog, data from various sources are combined to form a record from which one can retrieve information about oneself and the environment in which one is situated. It could be considered similar to an automated biography. Lifelog technology is still at an early stage of development. However, the history of lifelogs so far shows a clear academic, corporate and governmental interest. Therefore, a thorough inquiry into the ethical aspects of lifelogs could prove beneficial to the responsible development of this field. This article maps the main ethically relevant challenges and opportunities associated with the further development of lifelog technologies as discussed in the scholarly literature. By identifying challenges and opportunities in the current debate, we were able to identify other challenges and opportunities left unmentioned. Some of these challenges are partly explained by a blind spot in the current debate. Whilst the current debate focuses mainly on lifelogs held by individuals, lifelogs held by governmental institutions and corporations pose idiosyncratic ethical concerns as well. We have provided a brief taxonomy of lifelog technology to show the variety in uses for lifelogs. In addition, we provided a general approach to alleviate the ethical challenges identified in the critical analysis

Ethics of lifelog technology

In a lifelog, data from different digital sources are combined and processed to form a unified multimedia archive containing information about the quotidian activities of an individual. This dissertation aims to contribute to a responsible development of lifelog technology used by members of the general public for private reasons. Lifelog technology can benefit, but also harm lifeloggers and their social environment. The guiding idea behind this dissertation is that if the ethical challenges can be met and the opportunities realised, the conditions will be optimised for a responsible development and application of the technology. To achieve this, it is important to reflect on these concerns at an early stage of development before the existing rudimentary forms of lifelogs develop into more sophisticated devices with a broad societal application. For this research, a normative framework based on prima facie principles is used. Lifelog technology in its current form is a relatively novel invention and a consensus about its definition is still missing. Therefore the author aims to clarify the characteristics of lifelog technology. Next, the ethical challenges and opportunities of lifelogs are analysed, as they have been discussed in the scholarly literature on the ethics of lifelog technology. Against this backdrop, ethical challenges and opportunities are identified and elaborated. The normative analysis concentrates on two areas of concern, namely (1) the ethical challenges and opportunities that result from the use of lifelog technology, and (2) the conditions under which one becomes a lifelogger. For the first, three sets of key issues are discussed, namely issues to do with (a) privacy, (b) autonomy, and (c) beneficence. For the second, one key set of issues is examined, namely issues to do with autonomy. The discussion of each set of issues is concluded with recommendations designed to tackle the challenges and realise the opportunities

Lifelogging user study:bystander privacy

Automatically and passively taking pictures (using lifelogging devices such as wearable cameras) of people who don’t know they’re having their picture taken raises a number of privacy concerns (from a bystander’s perspective). We conducted a study focussing on the bystanders’ concerns to the presence of augmented reality wearable devices in two contexts (one formal and one informal). The results suggests the need to embed privacy enhancing techniques into the design of lifelogging applications, which are likely to depend upon an array of factors, but not limited to the context of use, scenario (and surroundings), and content

Investigating older and younger peoples’ motivations for lifelogging with wearable cameras

People have a natural tendency to collect things about themselves, their experiences and their shared experiences with people important to them, especially family. Similar to traditional objects such as photographs, lifelogs have been shown to support reminiscence. A lifelog is a digital archive of a person’s experiences and activities and lifelog devices such as wearable cameras can automatically and continuously record events throughout a whole day. We were interested in investigating what would motivate people to lifelog. Due to the importance of shared family reminiscence between family members we focused our study on comparing shared or personal motivations with ten older and ten younger family members. We found from our results that both older and younger adults were more likely to lifelog for the purposes of information sharing and that reviewing lifelog images supported family reminiscence, reflection and story-telling. Based on these findings, recommendations are made for the design of a novel intergenerational family lifelog system

Die Rolle von Privatheit bei Self-Tracking und Lifelogging: Eine nutzerzentrierte Literaturreview

Die Vermessung des eigenen Erlebens sowie die Aufzeichnung der direkten Umwelt liegen derzeit im Trend. Die sogenannte Self-Quantification als auch das sogenannte Lifelogging basieren jedoch grundlegend auf der Sammlung und Verarbeitung von Daten. Daher beleuchtet dieser Übersichtsartikel die bisherigen Studien zur Nutzersicht auf die Privatheit bei Lifelogging und Self-Quantification. Neben den Motivatoren zur Nutzung dieser Praktiken werden mögliche Datenschutzbedenken und -probleme, das Vorhandensein eines Datenschutzbewusstseins sowie mögliche datenschutzwahrende Handlungen beleuchtet. Folgende Studien können auf der Basis dieses Überblicks Forschungslücken identifizieren und zum weiteren Verständnis der Selbstvermessung beitragen

Exploring the technical challenges of large-scale lifelogging

Ambiently and automatically maintaining a lifelog is an activity that may help individuals track their lifestyle, learning, health and productivity. In this paper we motivate and discuss the technical challenges of developing real-world lifelogging solutions, based on seven years of experience. The gathering, organisation, retrieval and presentation challenges of large-scale lifelogging are dis- cussed and we show how this can be achieved and the benefits that may accrue
