Panel Statement

Next generations distributed cyberspace technologies, such as cloud computing, social networking and mobile applications, are expected to evolve a global marketplace in cyberspace for a wide variety of resources and services. In such an extreme-scale marketplace, user entities in the roles of providers, brokers or consumers, are largely autonomous with vastly diverse trust profiles, requirements and capabilities. Managing trust relations for effective and efficient transactions at such unprecedented scale would require collaboration and automation from data gathering, storage and analysis, to trust computation and decision making. At the same time, our growing dependence on such collaborative and autonomic trust management systems and the newly-emerging challenges in protecting huge amounts of data that such infrastructures have to store, process and share have generated enormous concerns related to privacy. Breach or compromise of privacy has the potential to inflict tremendous socioeconomic damages to humans, organizations and societies. Hence, the goal of effective and efficient management of trust, and that of preserving privacy may appear as being at odds with each other. This panel will focus on discussing privacy issues against the goal of collaborative and autonomic management of trust to streamline transactions and collaborations across the resources, services and user/organization levels. In particular, the panel will focus on answering the following key questions:

  • Is collaborative autonomic management of trust in extreme-scale distributed environments fundamentally in conflict with privacy goals? The panelists will present views regarding how collaboration and automation may facilitate trust management while on the other hand might make it difficult to preserve privacy, and how enforcing privacy might severely reduce the ability to effectively and efficiently manage trust relations at a global scale with hugef diversity.
  • What holistic approaches/paradigms exist or are needed towards ensuring that we significantly enhance the balance between the need for collaborative and autonomic management of trust and the need for privacy preservation?

The panelists will discuss their views regarding what theory, approaches, paradigms, systems and policies are crucial to address the growing challenges in collaboration, automation, trust and privacy management more effectively and what paradigm shift is needed, if any. In particular, the panel will motivate the need for both evolutionary progress as well as revolutionary developments that may be needed to address the collaborative autonomic trust management versus privacy preservation issues.

Panel Statement

With the huge amounts of data being produced continuously by plethora of computing devices and infrastructures (enterprise data repositories, Internet of Things, monitoring devices such as in healthcare domain and surveillance activities, federated sensor/mobile networks, cyber-physical infrastructures, social networks, etc.), the key data handling tasks such as storing, processing, and analyzing, are increasingly becoming very difficult. BigData has thus emerged as an area representing these growing problems of handling data sets characterized by high volume, high velocity and variety. While large and dynamic data sets that can be easily generated today provide an opportunity for streamlining decision making capabilities, improving business intelligence, mining new knowledge and enabling new and enriched services, current data handling solutions have significant limitations. Solutions that employ collaborative systems, technologies and network infrastructures are crucial for addressing such BigData related challenges.

This panel will focus on identifying key BigData related challenges, limitations of current solutions (architectural, storage, algorithmic, etc.) that may be useful, and future research directions in this domain. Some big questions related to BigData, for instance, include:

  • How a collaborative cloud computing infrastructure may need to be leveraged to address BigData analytics problems?
  • What kind of new network and storage infrastructures may need to be developed?
  • How BigData may exacerbate security and privacy (S&P) problems, how it may be leveraged to solve some critical S&P problems?
  • What data and met-data modeling approaches are needed (such as for context, structure, multi-modality, quality, dependability, provenance, etc.) to support BigData handling tasks?
  • What are the challenges related to analytics and decision making capabilities related to quality and real-time aspect of BigData? How to model Human in the loop aspect of the analytics and decision making challenges?
  • etc.
