Steven Hetcher Anonymity, Pseudonymity & Online Privacy The Internet is changing the world in many ways. In some instances, completely new topics have emerged while in other instances, the Internet raises the stakes with regard to some issue that previously existed. The latter is the case with regard to the topics of anonymity and pseudonymity.1 Developments in the online world have made these topics dramatically more salient than ever before. Ultimately, very significant policy issues are raised; in particular, whether there is a right to online anonymity

DE GRUYTER OLDENBOURG it – Information Technology 2015; 57(2): 133–137 Self-Portrayals of GI Junior Fellows Dominik Herrmann* Online privacy: Attacks and defenses Abstract: I approach privacy issues on the Internet from two ends. On the one hand, I design and evaluate defen- sive measures, so-called privacy enhancing technologies (PETs), which can be used by individuals to protect them- selves against surveillance on the Internet. On the other hand, I study the efficacy of offensive techniques. I am es- pecially interested in passive surveillance techniques that


The article looks at primary and secondary ICT teachers’ attitude to social network sites and privacy protection on the Internet. Attention is devoted to student-teacher friendships within online network sites. The study includes a description of specific habits as well as a discussion of how teachers make decisions and what influences them.

The research has used in-depth semi-structured interviews, focusing on ICT teachers with differing views on the issue in question. Our investigations have been supported by triangulation, which involved accessing information about given teachers on social network sites. Data gained from interviews and triangulation has been processed using open coding.

The results of our investigation show that teachers appreciate SNS because of the possibility to communicate and keep in touch with people they know, including former pupils. Teachers are concerned about the risks associated with using SNS, particularly security and privacy risks, and they feel even more under threat due to their occupation. Some teachers decided not to reject their pupils’ friend requests for educational reasons, claiming SNS serve as a channel of communication to support teaching and learning.

share their reflections about and experiences with self-disclosure and privacy in internet environments. The findings demonstrate that young children are capable of imagining the moral consequences of disclosing personal informa- tion about oneself and about others. Their moral reflections are embedded in a more general concern of children’s vulnerability to other, more powerful in- formation circulators in their social networks, such as older children, siblings, but also parents or the internet crowd. A strong sense of children’s entitlements to online privacy is

There is little agreement within and across these groups as to what actions should be taken to ad- equately protect user data. In more recent years, the de- bate has often focused on conceptualisations with regard to rapidly

Rachana Ashetakr, Parikshit N. Mahalle and Gitanjali R. Shinde 5 Users’ privacy at online social networks in Indian context: comprehensive multiaged group survey and discussion Abstract: Nowadays, social media has become an important part of life. People across the world use social media for random purposes. They post their accomplish- ments, achievements, vacation photos and others on the social media. However, they do not often realize that they are attracting very serious incidents that can occur due to their posts. Online privacy is one of the crucial points


Personalized advertisement has changed the web. It lets websites monetize the content they offer. The downside is the continuous collection of personal information with significant threats to personal privacy. In 2002, the European Union (EU) introduced a first set of regulations on the use of online tracking technologies. It aimed, among other things, to make online tracking mechanisms explicit to increase privacy awareness among users.

Amended in 2009, the EU Directive mandates websites to ask for informed consent before using any kind of profiling technology, e.g., cookies. Since 2013, the ePrivacy Directive became mandatory, and each EU Member State transposed it in national legislation. Since then, most of European websites embed a “Cookie Bar”, the most visible effect of the regulation.

In this paper, we run a large-scale measurement campaign to check the current implementation status of the EU cookie directive. For this, we use CookieCheck, a simple tool to automatically verify legislation violations. Results depict a shady picture: 49 % of websites do not respect the Directive and install profiling cookies before any user’s consent is given.

Beside presenting a detailed picture, this paper casts lights on the difficulty of legislator attempts to regulate the troubled marriage between ad-supported web services and their users. In this picture, online privacy seems to be continuously at stake, and it is hard to reach transparency.
