Online link disclosure strategies for social networks

International audienceWhile online social networks have become an important channel for social interactions, they also raise ethical and privacy issues. A well known fact is that social networks leak information, that may be sensitive, about users. However, performing accurate real world online privacy attacks in a reasonable time frame remains a challenging task. In this paper we address the problem of rapidly disclosing many friendship links using only legitimate queries (i.e., queries and tools provided by the targeted social network). Our study sheds new light on the intrinsic relation between communities (usually represented as groups) and friendships between individuals. To develop an efficient attack we analyzed group distributions, densities and visibility parameters from a large sample of a social network. By effectively exploring the target group network, our proposed algorithm is able to perform friendship and mutual-friend attacks along a strategy that minimizes the number of queries. The results of attacks performed on active Facebook profiles show that $5$ different friendship links are disclosed in average for each single legitimate query in the best case

Social network profiles as information sources for adolescents' offline relations

This paper presents the results of a study concerning the use of online profile pages by adolescents to know more about “offline” friends and acquaintances. Previous research has indicated that social networking sites (SNSs) are used to gather information on new online contacts. However, several studies have demonstrated a substantial overlap between offline and online social networks. Hence, we question whether online connections are meaningful in gathering information on offline friends and acquaintances. First, the results indicate that a combination of passive uncertainty reduction (monitoring a target’s profile) and interactive uncertainty reduction (communication through the target’s profile) explains a considerable amount of variance in the level of uncertainty about both friends and acquaintances. More specifically, adolescents generally get to know much more about their acquaintances. Second, the results of online uncertainty reduction positively affect the degree of self-disclosure, which is imperative in building a solid friend relation. Furthermore, we find that uncertainty reduction strategies positively mediate the effect of social anxiety on the level of certainty about friends. This implies that socially anxious teenagers benefit from SNSs by getting the conditions right to build a more solid relation with their friends. Hence, we conclude that SNSs play a substantial role in today’s adolescents’ everyday interpersonal communication

New Media & Youth Identity. Issues and Research Pathways

Media have held a considerable and growing place in the social environment of industrial society in recent decades, transforming the perception that a people have of their place in the world and of their memberships and belonging, creating new paths for social relations, affecting lifestyles, socialization, and communication processes, and the construction of identity itself. The relationship between young people (especially teenagers and adolescents) and new media shows some peculiarities which are worth further reflection to understand the extent and outcomes of these social changes. This article aims to investigate the discourse on youth identity and new media in the social science literature, determining which are the key trends and exploring the more relevant research questions about this theme and the way these topics relate to one another. Titles and abstracts of articles published during the period 2004 \u2013 2013 were selected from the Scopus social sciences database and they were analysed using different content analysis techniques supported by the T-Lab software. The international literature on these topics presents a certain liveliness and heterogeneity in themes and its perspectives on theoretical and empirical research. Nevertheless, it has been possible to identify some key trends, focusing mainly on the idea of active identity construction by new media

Couldn't or Wouldn't? the Influence of Privacy Concerns and Self-Efficacy in Privacy Management on Privacy Protection

Sampling 515 college students, this study investigates how privacy protection, including profile visibility, self-disclosure, and friending, are influenced by privacy concerns and efficacy regarding one's own ability to manage privacy settings, a factor that researchers have yet to give a great deal of attention to in the context of social networking sites (SNSs). The results of this study indicate an inconsistency in adopting strategies to protect privacy, a disconnect from limiting profile visibility and friending to self-disclosure. More specifically, privacy concerns lead SNS users to limit their profile visibility and discourage them from expanding their network. However, they do not constrain self-disclosure. Similarly, while self-efficacy in privacy management encourages SNS users to limit their profile visibility, it facilitates self-disclosure. This suggests that if users are limiting their profile visibility and constraining their friending behaviors, it does not necessarily mean they will reduce self-disclosure on SNSs because these behaviors are predicted by different factors. In addition, the study finds an interaction effect between privacy concerns and self-efficacy in privacy management on friending. It points to the potential problem of increased risk-taking behaviors resulting from high self-efficacy in privacy management and low privacy concerns.Radio-Television-Fil

Gay men’s experiences coming out online : a qualitative study

The current study employed qualitative methodology to investigate the experiences of 12 men who came out online, using Facebook. Analysis of coding data yielded several key themes. First, gay men discussed a range of experiences that influenced their online disclosure including homophobia, internalized homophobia, and previous salient sexual identity disclosures. Participants also commonly expressed a variety of goals and concerns about coming out online, including improving relationships and loss of friends. Finally, gay men identified several benefits to coming out on Facebook, including increased efficiency in coming out as compared to face-to-face disclosures, increased authenticity, and decreased ambiguity about their sexuality. Results are discussed within the context of literature on men’s coming-out experiences, men and masculinity and online identity management.Educational Psycholog

Development and Maintenance of Self-Disclosure on Facebook: The Role of Personality Traits

This study explored the relationships between Facebook self-disclosure and personality traits in a sample of Italian users. The aim was to analyze the predictive role of Big Five personality traits on different parameters of breadth and depth of selfdisclosed behaviors online. Facebook users, aged between 18 and 64 years of age (Mage = 25.3 years, SD = 6.8; N = 958), of which 51% were female, voluntarily completed an online survey assessing personality traits and Facebook self-disclosure. Results at a series of hierarchical regression analyses significantly corroborated the hypotheses that high extroverted and openness people tend to disclose on Facebook a significant amount of personal information, whereas high consciousness and agreeableness users are less inclined to do it. Furthermore, more extroverts and agreeableness people develop less intimacy on Facebook, differently from those with high levels of openness. Results also corroborated the hypothesis of a full mediation of time usage in the relationship between personality factors such as extroversion and conscientiousness with breadth of Facebook self-disclosure. Overall, according to the findings of the current study, personality traits and Facebook self-disclosure become central both as predictive variables for depicting the different profiles of potential addicted and as variables to help educators, teachers, and clinicians to develop training or therapeutic programs aimed at preventing the risk of Internet addiction. Limitations of the study are discussed, and directions for future research are suggested

Research in multi-cultural relationship building

This study aims to explore the ‘missing gap' between the values of an Accounting firm and the preference shown by Maaori on how they would like to be approached when wanting to build a trusted relationship within a business sense. This study makes use of qualitative approaches in which data is collected primarily through interviews and analysed to produce results and recommendations. The study found that Maaori would like to be approached in a way that makes sense to them and also identifies with their cultural proceedings. It also provides insight into how important trust is when establishing a relationship with Maaori. The study recommends that further studies conducted should interview a wider variety of focus groups to add different elements to this research and that FIRM A's small business department's offerings do not align with what Maaori want so need to be rethought to adapt to Maaor expectations

Shyness and Online Social Networking Services

Online social networking services are Internet websites that allow individuals to learn about and communicate with others. This study investigated the association between use of these websites and friendship quality for individuals varying in shyness. Participants (N = 241) completed questionnaires assessing their use of Facebook, an online social networking service, shyness, perceived available social support, loneliness, and friendship quality. Results indicated an interaction between shyness and Facebook usage, such that individuals high in shyness (when compared to less shy individuals) reported stronger associations between Facebook use and friendship quality. Facebook use, however, was unrelated to loneliness among highly shy individuals. Therefore, online social networking services may provide a comfortable environment within which shy individuals can interact with others
