The purpose of this paper is to analyse the problem of privacy disclosure of third party applications in online social networks (OSNs) through Facebook, investigate the limitations in the existing models to protect users privacy and propose a permission-based access control (PBAC) model, which gives users complete control over users’ data when accessing third party applications.

A practical model based on the defined permission policies is proposed to manage users information accessed by third party applications and improve user awareness in sharing sensitive information with them. This model is a combination of interfaces and internal mechanisms which can be adopted by any OSN having similar architecture to Facebook in managing third party applications, without much structural changes. The model implemented in Web interface connects with Facebook application programming interface and evaluates its efficacy using test cases.

The results show that the PBAC model can facilitate user awareness about privacy risks of data passed on to third party applications and allow users who are more concerned about their privacy from releasing such information to those applications.

The study provides further research in protecting users’ privacy in OSNs and thus avoid the risks associated with that, thereby increasing users’ trust in using OSNs.

The research has proven to be useful in improving user awareness on the risk associated with sharing private information on OSNs, and the practically implemented PBAC model guarantees full user privacy from unwanted disclosure of personal information to third party applications.

This study attempts to develop an efficient concept to mitigate the risks of social engineering in the era of social networks. For instance friend requests on Facebook are often accepted blindly, thus granting unknown people access to profile details. These problems fuel requirements for an application, developed in this study, that raises awareness of security issues in Facebook.

The “Theory of Planned Behaviour” (TPB), a model from psychology to predict behaviour, is used as a theoretical foundation for the application. Attitudes, perceived behavioural control and social norms are the main variables of this model. Social norms can be massively affected by the Facebook friends and therefore an application is developed which uses this in order to raise awareness.

The application propagated itself virally. Out of 117 users of the application, 15 took action to change the public‐search option visibility from public to private. The use of the application took on average 10.5 minutes.

Applications that scan a Facebook profile for fishy content already exist. However, at the time of writing this paper, no application specifically written against social engineering was known to the author.

This paper aims to report on lessons learnt from operating a location‐aware mobile social networking application, and critical functionalities that were deemed necessary in order to provide a pleasant user experience. As a result of user feedback, the authors enhanced their social networking system, G2G, with functionalities such as login with Facebook.com credentials without the need to sign up to their system first, and a much improved localization system that works across different mobile operators. Mobile advertisement was included for enhancing the user experience.

A modular approach has been followed for the system design. The original G2G system interfaced cleanly with the Facebook application programming interfaces (APIs) and the mobile advertisement subsystem through wrapper components.

The result was a much improved user experience as existing Facebook subscriptions facilitated new users to use the system. Mobile advertisement functionalities were seen as an essential add‐on. The aforementioned functionalities, combined with the ability to upload/search/download location‐aware multimedia notes, and a back‐end interface that allows advertisers to add location‐aware, personalized content, resulted in a significantly enhanced user experience as evidenced by higher user active participation to the system.

The enhanced system integrates seamelessly with Facebook (facilitating thus the entry of new users) and with a mobile advertisement platform, and provides for advanced security functionalities. Moreover, it supports Android‐based smart‐phones.

The purpose of this paper is to examine the strategic use of social media and chat applications of women entrepreneurs to promote their businesses.

Because of the nature of the study and dearth of sufficient data in the Middle Eastern society on the women entrepreneurship, this study employed a qualitative research methodology. The research comprised of 20 in-depth interviews with immigrant women entrepreneurs in the United Arab Emirates. They were identified through personal contacts and referrals.

All the expatriate women interviewed are using social media and chat applications to promote their business. Facebook is used for brand creation and WhatsApp is used as a direct marketing tool to evoke purchase response. Though traditional promotional tools are far from redundant, their role is more supplementary. The increasing trend is a combination of traditional tools and digital tools. Digital tools seem to have an upper hand in their business promotions.

This study is limited to SME sector in one industry and in one country. The qualitative nature of this study could affect the generalizability of the results. A more extensive study is needed and future research should be more diverse including widening the selection of respondents, industries and countries.

This study is a novel attempt to gauge an in-depth understanding of modern communication tools. It looks specifically at the integrative strategies pursued by the immigrant women entrepreneurs using Facebook and WhatsApp.

The purpose of this paper is to examine whether Library and Information Science (LIS) students' patterns of Facebook use are affected by personality characteristics (e.g. extroversion, introversion, self‐esteem) and by their perceptions about Facebook.

Different questionnaires were distributed to 140 LIS students in a prominent LIS department in Israel.

The present research revealed that personality characteristics as well as gender, level of education and age influence both LIS students' patterns of Facebook use, and their perceptions about Facebook.

LIS educators should expose MA and PhD students more to social networking sites, enabling them to experience their advantages and disadvantages in the personal as well as professional realms. This exposure may cause these students to use social networks in their future work as librarians or information scientists, understanding that these platforms can serve as an additional channel of communication with their patrons.

The findings emphasize the importance of individual differences in technology use and acceptance, and may lead to further research in this field.

A huge amount of personal and sensitive data are shared on Facebook, which makes it a prime target for attackers. Adversaries can exploit third-party applications connected to a user’s Facebook profiles (i.e. Facebook apps) to gain access to this personal information. Users’ lack of knowledge and the varying privacy policies of these apps make them further vulnerable to information leakage. However, little has been done to identify mismatches between users’ perceptions and the privacy policies of Facebook apps. This paper aims to address this challenge in the work.

The authors conducted a lab study with 31 participants, where the authors received data on how they share information on Facebook, their Facebook-related security and privacy practices and their perceptions on the privacy aspects of 65 frequently-used Facebook apps in terms of data collection, sharing and deletion. The authors then compared participants’ perceptions with the privacy policy of each reported app. Participants also reported their expectations about the types of information that should not be collected or shared by any Facebook app.

The analysis reveals significant mismatches between users’ privacy perceptions and reality (i.e. privacy policies of Facebook apps), where the authors identified over-optimism not only in users’ perceptions of information collection but also in their self-efficacy in protecting their information in Facebook despite experiencing negative incidents in the past.

To the best of the knowledge, this is the first study on the gap between users’ privacy perceptions around Facebook apps and reality. The findings from this study offer direction for future research to address that gap through designing usable, effective and personalized privacy notices to help users to make informed decisions about using Facebook apps.

The purpose of this paper is to describe applications, gadgets, and profiles that libraries have developed and distributed through the Facebook, iGoogle, and MySpace communities.

Growing number of libraries and library‐related organizations are creating practical tools using Web 2.0 technologies.

Librarians need to keep abreast of and experiment with these new methods of packaging and delivering information.

The purpose of this paper was to develop a framework of working-together relations and investigate ways to enhance working-together relations among people, organisations, communities and neighbourhoods using working-together applications. Today, people in communities, neighbourhoods and constituencies often work together in a coalition of public, private and non-profit institutions. The technology used today has enabled new forms of communications and collaboration. The rapid growth of mobile technologies and interactive, collaborative applications based on Web technologies has enabled the development of new approaches to derive and share organisational and local knowledge. Not all of these applications have succeeded; after a certain time, users tend to stop using online applications that do not assist them in developing collaborative practices with their team members.

To better understand the essential characteristics of a successful online application that effectively supports people to work together, the authors undertook an inductive analysis of related literature and existing social media application.

By combining and categorising the findings, it was possible to articulate the characteristics associated with four identified categories of working-together relations: networking, coordination, cooperation and collaboration. The study also identified essential activities that are performed in each working-together category and the factors that enable successful working-together relations: trust, risk and rewards.

Future studies will look into how applications could be further enhanced, so that, for example, an application that is currently classified as “coordination” could be improved and the required characteristics of “collaboration” could be met.

It is expected that the framework derived will assist in the design of successful online applications to support different categories of working-together relations.

The main contribution of this study is a new framework that can now be used to identify how effective an existing application can be in assisting the working-together relations.

The purpose of this paper was to develop a new interactive guiding system allowing people to use their own smart mobile devices, such as smart phones or tablet PCs, to activate the guiding services at the art gallery. The system provided interactions between visitors and exhibit items. It focused on the highly interactive functions between visitors and artworks authors as well as among visitors at both exhibition sites and social network sites (SNSs).

The system used quick response (QR) codes as the context aware elements, Facebook as the platform of SNSs, and smart mobile devices as the human-machine interfaces. Visitors carrying their own smart phones or tablet PCs can activate the guiding services by scanning the QR codes of the interested exhibit items. A system usability scale (SUS) survey was conducted to understand the visitors' perceptions on system usability. A questionnaire survey was conducted to collect the visitors' and authors' attitudes on releasing messages through Facebook.

The system was implemented at an art centre where lacquer artworks were on display. The SUS survey showed that 94 per cent of the participated visitors have satisfactorily rated this new guiding system, indicating rather high usability of the system. Most participated visitors agreed on Facebook as an ideal channel to release messages and they would pay more attention to the highly-recommended exhibit items. All the artworks authors consented to this new guiding system with potential power to disseminate their works over the cyberspace.

This new system possesses some important features in blending real world and cyberspace activities. Visitors at exhibit sites can become more informed and captivated because the interactive guiding system enables them to share knowledge and commentary opinions with others who were, are or will be at the same exhibition. It also allows people to share with their cyberspace friends who may have no times or opportunities to visit the exhibition. Most importantly, the new system may immensely expand the number of potential visitors in ways to make the authors and their artworks rapidly recognized.

The purpose of this paper is to investigate the applications of social media in digital libraries and identify related problems.

A total of ten institutions were selected from the following cultural institution types – public libraries, academic libraries, museums, government, and international organisations – to represent a variety of digital libraries developed or sponsored by different types of organisations. The social media applications were examined with regard to the following aspects: types of social media, placement of social media, updating social media, types of interactions, and types of functions.

This study presents the types of social media applications in the selected digital libraries and further characterises their placements, update frequency, types of interactions between digital librarians and users, as well as various types of roles they played. In the process of analysis the authors also identified problems related to lack of standards, creating two-way communication channels, and the lack of education functions.

Further research needs to expand the selection of institutions and digital libraries to have more representative sampling, in particular institutions that are outside North America and Europe. It is also important to perform in-depth content analysis of social media to identify patterns and functions that social media perform. Moreover the authors will compare specific social media tools, such as Twitter, Facebook, etc., across institutions. In order to explore fully the reason why certain social media tools are implemented in digital libraries, it is important to survey or interview digital librarians of digital libraries in different types of cultural institutions. In addition users can be interviewed to solicit their perspectives about their usage of social media in digital libraries.

This study not only examines the current status and problems of social media application in digital libraries but also offers suggestions on making good use of social media to connect users and digital libraries.
