On User Perception of Authentication in Networks

Lorentzen, Charlott January 2014 (has links)
Authentication solutions are designed to stop unauthorized users from getting access to a secured system. However, each time an authentication process occur an authorized user needs to wait in expectation of approved access. This effort can be perceived as either a positive or negative experience. If the effort is perceived as a security measure; the effort is usually perceived as a positive experience. On the other hand, if the effort is perceived as a waiting time; the effort is usually perceived as a negative experience. The trade-off between security, user-friendliness and simplicity plays an important role in the domain of user acceptability. From the users' point of view, security is both necessary and disturbing at the same time. The overall focus in this thesis is on user perception of authentication in communication networks. An authentication procedure, or login, normally includes several steps and messages between a client and a server. In addition, the connection could suffer from low Quality of Service, i.e., each step in the authentication process will add to a longer response time. The longer response times will then infer lower Quality of Experience, i.e., a worse user perception. The thesis first presents a concept of investigating user perception. A framework is developed in which different criteria and evaluation methods for authentication schemes are presented. This framework is then used to investigate user perception of the response times of a web authentication procedure. The derived result, which is an exponential function, is compared to models for user perception of web performance. The comparison indicates that users perceive logins similarly, but not identically, to how they perceive standard web page loading. The user perception, with regards to excessive authentication times, is further studied by determining the weak point of the Extensible Authentication Protocol Method for GSM Subscriber Identity Modules (EAPSIM) with the OpenID service. The response times are controllably increased by emulating bad network performance for EAP-SIM and other EAP methods in live setups. The obtained results show that one task of the EAP-SIM authentication deviates from the other tasks, and contributes more to the total response time. This deviation points out the direction for future optimization. Finally, this thesis investigates how users of social networks perceive security, and to which extent they contribute to it. One way of contributing to security by creating and using strong authentication credentials, e.g. passwords. Websites might enforce a password length which is insufficient to provide a strong password. This might then cause problems by giving users a false perception of what constitutes a strong password. The origin of the password problem, namely the construction of passwords, and the user perception of password security is studied. A survey is conducted and the results indicate that the passwords of the respondents are not as strong as the respondents perceive them to be.

Be active or stay unattractive : Be active or stay unattractive

Naess, Erik January 2017 (has links)
Enterprises utilize information and communication technology, including websites, to market themselves and expand their businesses. However, employing this technology is not always a guarantee of success, especially for small enterprises. This is often due to limited resources and to the extent of having web skills present within the enterprise. Deciding who will design the website for a small enterprise is therefore of importance since a well designed website is a requirement to attract interest in visitors. The design of a website is also a main factor for the first impression to a visitor, a website that is visually appealing tends to give a greater confidence at first glance. This thesis is based on the interest of small enterprises considerations about what website design development characteristics and objective characteristics is generating more positive first impressions. To find this out, interviews together with subjective and objective measures of visual aesthetics were conducted to immerse in the aesthetics of small enterprise websites. The methods implemented gave variables to test in a correlation analysis. This correlation analysis showed that two web development characteristics had strong correlations with users' perception of visual aesthetics. None of the objective aesthetic attributes based on previous theories gave any strong correlations. These characteristics were therefore supplemented with other objective characteristics, which gave two strong correlations. / Företag använder sig informations- och kommunikationsteknik, inklusive hemsidor, för att marknadsföra sig själva och för att växa som företag. Användandet av denna teknik är dock inte alltid en garanti för framgång, särskilt inte för småföretag. Detta beror ofta på begränsade resurser och i den utsträckning att det finns kompetens inom webbprogrammering i företaget. Beslutet att bestämma vem som ska design hemsidan för ett litet företag är därför av stor betydelse, eftersom en väl designad hemsida är ett krav för att locka intresse för besökare på hemsidan. En hemsidas design är också en viktig faktor för det första intrycket hos en besökare av en hemsida. Hemsidor som är visuellt tilltalande tenderar att ge större förtroende vid första anblicken. Denna masteruppsats bygger på intresset hos småföretags överväganden om vilka webutvecklingsegenskaper och objektiva estetiska egenskaper i en webbdesign som genererar mer positiva första intryck. För att ta reda på detta, genomfördes intervjuer samt subjektiva och objektiva mätningar av visuell estetik för att fördjupa sig i estetiken hos småföretags hemsidor. De genomförda metoderna gav variabler att testa i en korrelationsanalys. Denna korrelationsanalys visade att två utvecklingsegenskaper hade starka korrelationer med användares perception av visuell estetik. Ingen av de objektiva estetiska egenskaperna baserade på tidigare teorier gav starka korrelationer. Därför kompletterades dessa med andra objektiva egenskaper där två av dem gav starka korrelationer.

Effektivare materialflöden med människan i centrum : En fallstudie inom BillerudKorsnäs godsmottagning

Jonuzi, Taulant, Sager, Josefin January 2019 (has links)
With the development of society, organizations are increasingly working to streamline their businesses to maintain and strengthen their position on the market. This can be carried out in several different ways, since businesses are individual and require special needs to develop longterm sustainability. The purpose of this case study is to emphasize how material flows within industrial goods reception can be streamlined based on human aspects. To answer the purpose, data was collected through interviews, observations and literature studies. Six interviews have been conducted at BillerudKorsnäs, with observations taking place continuously during the study. This is to create a reality perception with different approaches to increase the credibility of the study. The results were analyzed and discussed with the help of literature reviews. The literature studies consist of collected scientific articles, course literature, web pages and other credible sources. The results are based on a study of internal material flow in the central repository at BillerudKorsnäs in Gävle. As discovered, the material flow consists of mainly manual labor that lead to unnecessary time-consuming disturbances. A contributing factor to improve and streamline the material flow has been built on identifying health-promoting measures. Therefore, industrial goods reception can be made more efficient with the help of digital aids concerning to human aspects.

Student Perspectives on School Surveillance : an Explorative Study Using a Mobile Application Prototype

Persson, Anton, Eleyan, Ahmed January 2019 (has links)
Schools should be safe places for young people to learn through freely expressing and sharing ideas. This requires respecting student privacy, as they otherwise feel distrusted and uncomfortable. At the same time, surveillance is becoming an increasingly important part of facilitating a safe school environment. This has created an interesting dynamic where increasingly pervasive surveillance solutions seeking safety and other benefits are threatening student privacy. Therefore, researchers stand before the urgent challenge of figuring out what is a desirable direction for this technology. This qualitative study focuses on students’ perspectives on surveillance and privacy. Data was collected through interviews, card sorting, and the use of a prototype together with scenarios. The results of the study expand upon current research and reveal that actively involving students in design and research processes is important to ensure sustainable solutions. Students desire more value in terms of control, assistance, safety and information. At the same time, many concerns about discomfort, distrust and abuse are present. A set of guidelines on important considerations for future surveillance research and design are presented which focus on collaboration, responsibilityand creativity. Key issues causing inefficient communication between studentsand researchers are discussed, and the need for providing further education on the topic is motivated.

SINCE THE BEGINNING OF THIS INTERVIEW I HAVE MANAGED FOUR EMAILS : A qualitative study of email management for information workers

Forsman, Kristoffer, Horned, Arvid January 2019 (has links)
As a result of the rapid development of technology and the implementation of it in work environments, productivity and profit can increase for an organization. Email has led to much shorter ways of communication but there are also less positive aspects of technology. Technostress, information overload and email overload are all three effects of this new ubiquitous digital era. We ask how individual information workers manage and reply to incoming email, to extend our knowledge regarding the effects of email overload on information workers, and to identify their coping strategies in their work life context. This knowledge can be used by practitioners, designers and researchers to develop email as a service further. By conducting nine qualitative interviews with information workers employed in three different organization, we found that balance in email management is important to utilize the full potential of the service, and it would be useful for individuals, as well as organizations, to establish clear rules regarding email use both within work hours, as well as on leisure time.

HIGH SCORE : A qualitative study on how gaming can further awareness in office environments

Bergqvist, Joakim, Breuer, Sebastian January 2019 (has links)
Gamification as an educational tool has been explored extensively in traditional academic contexts such as universities and schools. There is however a lack of research on the usage of games for educational purposes in organizations, and even less research has evaluated games’ potential in creating organizational awareness. To understand if companies could benefit from gamification, this study looked at how employees’ professional backgrounds, social interaction and context during a game experience can influence employees’ awareness of the organization. In order to do that, a digital game that portrayed the supply chain process of an industrial company and focused on specific key aspects was built and tested with 17 employees in a large international organization. The results show that digital games can further both awareness of the organization by letting employees play and experience key aspects of the delivery process. The most noticeable increase in awareness were with the participants whose work is not directly involved in the supply chain.

An investigation into methods for capturing corporate knowledge in an Australian local government context

O'Donnell, Kye January 2007 (has links)
This research project investigates the processes of capturing corporate knowledge in an Australian local government context. The City of Perth, the capital city local government of Perth, Western Australia, is the organisation within which this study was conducted. A qualitative research methodology was utilised for this study in order to understand all the factors involved in knowledge sharing, including the human aspects. Data was collected exclusively through structured interviews consisting of a series of open questions. Digital transcripts of these interviews were produced and analysed by the researcher using qualitative data analysis software. The application of the research methodology has produced a rich set of results. The different types and sources of corporate knowledge used by participants and their views on knowledge capture processes are explored. Participants provide insight into their motivations in undertaking knowledge capture, the extent knowledge is shared in the organisation and barriers to sharing knowledge that they had encountered. The utilisation of the organisation’s information management processes and the overall purposes of knowledge capture were also explored by the study. Some of the results are quite predictable and generally supported by the literature, such as a preference for interpersonal communication in the sharing of knowledge. Other results are more unexpected including strongly expressed altruistic support for the good of the employing organisation as their motivation in supporting knowledge management activities and an understanding of the need for knowledge codification.

The interactive museum lab : Design of a mobile room that includes people with disabilities in a culture house setting

Ramírez Martínez, Natalia January 2016 (has links)
This study has been carried out from two points of view: how museums have changed to adapt to new technologies and the inclusion of people with different disabilities as a target group when developing a new product. This study is done through a series of qualitative interviews made to museum staff and personnel related to the target group, belonging to working directly any of the groups in which the disabilities are divided. Through the study and the application of their answers and contributions as well as the data collected in previous studies, the development of an interactive-multimedia Lab was accomplished, which is installed in the museum Kulturfabriken in Skövde. In order to execute a product development process properly, an adequate methodology was developed, which combines working methods, focused directly on the elaboration of the product from the most practical point of view and analysis methods, which helped analyze the process in an appropriate way through the different interviews and meetings held with the focus groups, to make a customized product with the needs of the museum, but also to combine the needs of the groups with disabilities and special features such as: surround sound system and immersive space, in order to create a suitable multimedia space.

Förskollärares digitala kompetens : en kvalitativ studie angående några förskollärares upplevelser av sin digitala kompetens och arbete med IKT / Preschool teachers’ digital skills : a qualitative study regarding some preschool teachers’ experiences of their digital skills and work with ICT

Strand, Gustav, Mattsson, Olof January 2018 (has links)
Studiens syfte var att undersöka hur några förskollärare upplever digital kompetens, hos sig själv samt i verksamheten, deras upplevelser av hur digital kompetens kan påverka deras arbete med IKT och deras upplevelser av att arbeta med IKT. Forskningsfrågorna lyder: Hur upplever några förskollärare sin digitala kompetens? Hur upplever några förskollärare att deras digitala kompetens påverkar hur de arbetar i förskolans verksamhet? Hur upplever några förskollärare arbete med IKT? Studien har en kvalitativ forskningsansats med semistrukturerade intervjuer som datainsamlingsmetod. Det har medverkat sex förskollärare från sex olika verksamheter i studien. Bearbetning av det insamlade materialet skedde genom en fenomenologisk analys samt en tematisk analys. Analysen presenteras i fyra kategorier: förskollärares upplevelser av digital kompetens, ett kvalitativt arbete med IKT, stöd och möjligheter för kompetensutveckling samt styrdokumentens roll och förväntningar. Resultatet visade på en skillnad mellan förskollärares definition av digital kompetens och hur skolverket definierar digital kompetens. Det framkom även en stor variation i hur säkra förskollärare upplever sig vara i sitt arbete med IKT. Resultatet visar även att det finns en skillnad mellan tillgången till digitala verktyg i verksamheter samt tillgång till kompetensutveckling. Slutsatsen är att arbete med IKT i förskolans verksamhet har en koppling till hur förskollärare ser på sin egna digitala kompetens, deras attityd och intresse till arbete med IKT samt de digitala möjligheter som verksamheten har att erbjuda.
