Trends and Challenges in Security and Privacy from the Public Health Care Perspective

The health care industry is data-rich by far. Every encounter with the system results in an electronic footprint. The promises of connectivity – electronic and personal health records, patient-centered health care, clinical warehousing, home monitoring, distance medicine, health care public clouds, community of practice social networking, ubiquitous computing and more – mean exponential increases in data and, in tandem, exponential opportunities for breaches of privacy and security of personal health information. Moreover, the security and privacy issue is becoming more complex with the quest for greater efficiency in health systems and the encouragement of governments and health care institutions to bring together two fields of practice that have largely developed in parallel in industrialized countries: public health and health care. On top of all of that, patients want convenient and realtime access and control to their data. This environment drives governments and health care institutions to promote customer-centric strategies while simultaneously improving internal efficiencies and information sharing. However, the ad hoc implementation of technology will not resolve these pressures. Technology decisions must be based on a sound understanding of the business issues that drive customer needs. The current environment requires a new model—one in which health care leaders effectively fuse business and technology decisions. This invited speech provides a primer on risks associated with privacy and security in health care and guidance about industry preparedness as well as to shed light on the challenges an solutions to the security and the privacy issues. In particular, the issue of identity management (IdM) is centeral to every solution. Identity management (IDM) has been around since the first mainframe, but with one machine and one user, it wasn't much of an issue. As business computing evolved to the client/server architecture, many users would access a handful of applications. That made federated identity management (across all the apps) a little more complex -- but passwords still did the job. Today, in a virtualized cloud environment where users located anywhere might access dozens of healthcare applications that involves patient health records (such as CCRs by Google Health and CCDs by Microsoft) on numerous devices; federated identity management has become the Holy Grail.

About Dr. Sabah Mohammed
Dr. Sabah Mohammed started his career during 1977 as a Multimedia Maintenance Engineer working for Canon and Sony following his hobby in Electronics, although he completed his bachelor degree in Mathematics (HBSc 1977). From July 1979 he started his graduate studies where he received his degrees in Computer Science from Glasgow University-UK (PgD 1980, MPhil 1981) and from Brunel University-UK (PhD 1986). Since late 2001, Dr. Mohammed is a full Professor of Computer Science at Lakehead University. Formerly, from 1986-1995, Dr. Mohammed was an Assistant/Associate Professor of Computer Science at various universities including (BU, Amman University, Philadelphia University, Applied Science University and HCT). Sabah is interested in intelligent systems that have to operate in large, nondeterministic, cooperative, survivable, adaptive or partially known domains. Although his research is inspired by his PhD work on the employment of some Brain Activity-Structures based techniques for decision making (planning and learning) that enable processes (e.g. agents, mobile objects) and collaborative processes to act intelligently in their environments to timely achieve the required goals, Sabah extended his research vision to include constructivism and focus more on the nature of knowledge. Since knowledge is created by people and influenced by their values and culture, Sabah research stated to shift more towards net centric systems (e.g. Cloud Computing, Social Networking and Enterprise Systems, Web-Based Systems). During the last nine years, Sabah research is focused on developing ubiquitous healthcare systems that enable sharing securely knowledge and data in an effective way. In particular sharing Electronic Health Record (EHRs) over the Web is one of the very challenging problems that Sabah tries to solve. Sabah believes that finding good solutions for sharing EHRs requires approaches that cut across many different fields (e.g. Semantic Web, Web 2.0, Web 3.0, Ubiquitous Computing, Medical Informatics, XML Security and Artificial Intelligence).. He published several research articles in an attempt to promote EHRs interoperability and sharing. Recently he edited and authored a notable book on “Ubiquitous Health and Medical Informatics: The Ubiquity 2.0 and Beyond” by IGI Global that will be published during April 2010.

Structure and Model of Algorithms

Design and analysis of algorithms depend on progress and development of computer architecture, and also depend on change of way of thinking. From the fast algorithms to parallel algorithms, from genetic algorithms to machine learning, from evolution computing to soft computing, design method and evaluation standard of algorithms are appearing various directions. What is the algorithm? Does it exist an identical algorithm model to explain all algorithm architectures? Does it exist an identical evaluation standard to evaluate the computational complexity of different algorithm architecture? In this speech, we would discuss architecture and characteristic of every kind of algorithm to provide some materials for finding this identical algorithm model.

Environmental Diversity Techniques of Software Systems

Several recent studies have reported that most outages in technical computer-based systems are due to software faults. Traditional methods in software engineering are fault avoidance/removal based on extensive testing/debugging, and fault tolerance based on design/data diversity. Sinceboth of them are very expensive and unrealistic in common cases, the key challenge then is how to provide highly dependable software with relatively cheaper cost.
We introduce several environmental diversity techniques of software systems, and overview the typical examples involving checkpoint restart and software rejuvenation. Based on the author's own research results during a past decade, we discuss stochastic models to derive several checkpoint restart and software rejuvenation policies analytically in terms of the optimality under cost criteria. The present research trend and the open problems in future are also discussed.

Cyber-Physical Intelligence in the context of Power Systems

Cyber-Physical Systems (CPS) are computing systems interacting with physical processes. CPS are typically designed as networks of interacting elements instead of as standalone devices. CPS use computations and communication deeply embedded in and interacting with physical processes to add new capabilities to physical systems. CPS must be dependable, secure, safe, efficient, and operate in real-time. They must also be scalable, cost-effective and adaptive. The integration of computational and physical processes exhibits a complex behaviour that cannot be analyzed by the computational or physical sciences alone. These systems also transcend traditional computer-controlled systems because of their scale, dependence on man-machine interaction and their rich communication infrastructure that is enabled by the Internet. CPS range from miniscule (pace makers) to large-scale (the national power-grid, blackout-free electricity generation and distribution, optimization of energy consumption).

This speech is dedicated to the integration of Intelligence in Cyber-Physical Systems. We will illustrate this with Power Systems. Power Networks’ critical physical infrastructure depends crucially on SCADA (Supervisory Control and Data Acquisition) and DCS (Digital Control Systems) for sensing, monitoring, gathering, and control of distributed physical infrastructures. Power Systems Control Centres are the place where all the information of SCADA and DCS arrive, and Control Centre Operators’ must handle the huge amount of data and information arriving from these systems, namely when we are in the presence of critical incidents. Now Cyber-Physical Intelligence is emerging as an important sub-area. The concept of Intelligent SCADA, with decentralized, flexible, and intelligent behavior, being dynamically adaptive to the context of the Power System is appearing.

Cyber-Physical Intelligence is a concept adequate to deal with Power Systems Smart Grids, Distributed Generation, mainly based on renewable sources, and Electricity Markets. We will present the project CITOPSY (Cyber-Ambient Intelligent Training of Operators in Power Systems Control Centres), in which the concept of Cyber-Physical Intelligence is being experimented.

Interactive Navigation of Image Collections

Image databases are growing at a rapid rate and hence efficient and effective techniques to manage these vast repositories are highly sought after. Image database navigation systems provide an interesting alternative to retrieval based approaches and in my talk, I will show how image browsers developed in our group can be used for interactive exploration of large image collections based on the principle that visually similar images are located close to each other thus helping user navigation, and that large datasets are handled through a hierarchical approach.
