TMA 4 Presentation: Social Computing Privacy and Security

Computer and human interaction has evolved and reached new levels with the advent of social networks and social computing. This paper investigates challenges with social computing, particularly technical challenges around the collection and management of data, security and privacy and mobile social computing. The number of users of social computing systems has grown exponentially and managing all the data produced by all the users presents a monumental infrastructure challenge. Social computing organizations have deployed hundreds of thousands of servers to safely store and quickly retrieve data. Privacy and security manifest themselves in many different ways, a level of confidence in the organizations handling of private data is necessary to attract users. Organizations user privacy policy set the legal limits to what and organization intends and is allowed to do with a user’s private info. Additionally an organization needs to protect the data’s confidentiality, availability and integrity from malicious hackers. Finally and organization needs to protect users from other users, mainly minor or vulnerable users from predators and bullies. Finally there is the challenge of mobile computing which introduces an extra dimension of physical space in addition to the time and content of all users data. With mobile computing users content is superimposed with time and space factors that draws a complete picture of a user’s activities and the organization now needs to handle that extra dimension in all its system design, data management, and privacy challenges.

ICARUS – Adaptive Tag Cloud Navigational and Recommender System

Current tagging systems experience several problems related to recommending accuracy of a resource. High number of users and related topical diversification, coupled with the unique vocabularies, as well as the popularity bias are some of the main obstacles to successful recommendation. The user interfaces, utilized for topical narrowing and searching for the specific term often fail at being intuitive and user friendly, mainly due to the inability to visualize subsequent navigational paths. This work presents a concept for ICARUS, a recommender system with integrated novel user interface, which attempts to produce an answer to these problems by utilizing approach for balancing of the user and popularity biases and an intuitive interface with navigational paths prediction. The research conducted focused on the user acceptance of the interface in order to provide the justification for the future development. The results showed that ICARUS interface has the potential to outperform the conventional ones.

Privacy of Networked Publics

This research looks at the concept of the “networked public” and subsequently investigates how this new type of meeting place affects the private/public dichotomy and personal/collective privacy. The goal of this research is to demonstrate some of the new technological and social challenges associated with the introduction of networked publics. An internet-based literature search was used to gather appropriate and timely information for this research. A networked public is a networked-enabled meeting place. The additional properties of the networked public change not only how we are able to com- municate but also how we must consider and deal with individual and collective privacy.
