Security in Pervasive Computing: Current Status and Open Issues

Million of wireless device users are ever on the move, becoming more dependent on their PDAs, smart phones, and other handheld devices. With the advancement of pervasive computing, new and unique capabilities are available to aid mobile societies. The wireless nature of these devices has fostered a new era of mobility. Thousands of pervasive devices are able to arbitrarily join and leave a network, creating a nomadic environment known as a pervasive ad hoc network. However, mobile devices have vulnerabilities, and some are proving to be challenging. Security in pervasive computing is the most critical challenge. Security is needed to ensure exact and accurate confidentiality, integrity, authentication, and access control, to name a few. Security for mobile devices, though still in its infancy, has drawn the attention of various researchers. As pervasive devices become incorporated in our day-to-day lives, security will increasingly becoming a common concern for all users - - though for most it will be an afterthought, like many other computing functions. The usability and expansion of pervasive computing applications depends greatly on the security and reliability provided by the applications. At this critical juncture, security research is growing. This paper examines the recent trends and forward thinking investigation in several fields of security, along with a brief history of previous accomplishments in the corresponding areas. Some open issues have been discussed for further investigation

Data privacy by design: digital infrastructures for clinical collaborations

The clinical sciences have arguably the most stringent security demands on the adoption and roll-out of collaborative e-Infrastructure solutions such as those based upon Grid-based middleware. Experiences from the Medical Research Council (MRC) funded Virtual Organisations for Trials and Epidemiological Studies (VOTES) project and numerous other real world security driven projects at the UK e-Science National e-Science Centre (NeSC – www.nesc.ac.uk) have shown that whilst advanced Grid security and middleware solutions now offer capabilities to address many of the distributed data and security challenges in the clinical domain, the real clinical world as typified by organizations such as the National Health Service (NHS) in the UK are extremely wary of adoption of such technologies: firewalls; ethics; information governance, software validation, and the actual realities of existing infrastructures need to be considered from the outset. Based on these experiences we present a novel data linkage and anonymisation infrastructure that has been developed with close co-operation of the various stakeholders in the clinical domain (including the NHS) that addresses their concerns and satisfies the needs of the academic clinical research community. We demonstrate the implementation of this infrastructure through a representative clinical study on chronic diseases in Scotland

Patient privacy protection using anonymous access control techniques

Objective: The objective of this study is to develop a solution to preserve security and privacy in a healthcare environment where health-sensitive information will be accessed by many parties and stored in various distributed databases. The solution should maintain anonymous medical records and it should be able to link anonymous medical information in distributed databases into a single patient medical record with the patient identity. Methods: In this paper we present a protocol that can be used to authenticate and authorize patients to healthcare services without providing the patient identification. Healthcare service can identify the patient using separate temporary identities in each identification session and medical records are linked to these temporary identities. Temporary identities can be used to enable record linkage and reverse track real patient identity in critical medical situations. Results: The proposed protocol provides main security and privacy services such as user anonymity, message privacy, message confidentiality, user authentication, user authorization and message replay attacks. The medical environment validates the patient at the healthcare service as a real and registered patient for the medical services. Using the proposed protocol, the patient anonymous medical records at different healthcare services can be linked into one single report and it is possible to securely reverse track anonymous patient into the real identity. Conclusion: The protocol protects the patient privacy with a secure anonymous authentication to healthcare services and medical record registries according to the European and the UK legislations, where the patient real identity is not disclosed with the distributed patient medical records

Assistance to Firefighters Program: Distribution of Fire Grant Funding

[Excerpt] Firefighting activities are traditionally the responsibility of states and local communities. As such, funding for firefighters is provided mostly by state and local governments. During the 1990s, shortfalls in state and local budgets, coupled with increased responsibilities of local fire departments, led many in the fire community to call for additional financial support from the federal government. Although federally funded training programs existed (and continue to exist) through the National Fire Academy, and although federal money was available to first responders for counterterrorism training and equipment through the Department of Justice, there did not exist a dedicated program, exclusively for firefighters, which provided federal money directly to local fire departments to help address a wide variety of equipment, training, and other firefighter-related needs

Vulnerable Youth: Federal Mentoring Programs and Issues

[Excerpt] Since the mid-1990s, Congress has supported legislation to establish structured mentoring programs for the most vulnerable youth. The Department of Justice’s Juvenile Mentoring Program (JUMP), the first such program, was implemented in 1994 to provide mentoring services for at-risk youth ages 5 to 20. The purpose of contemporary, structured mentoring programs is to reduce risks by supplementing (but not supplanting) a youth’s relationship with his or her parents. Some of these programs have broad youth development goals while others focus more narrowly on a particular outcome such as reducing gang activity or substance abuse, or improving grades. Research has shown that mentoring programs have been associated with some positive youth outcomes, but that the long-term effects of mentoring on particular outcomes and the ability for mentored youth to sustain gains over time are less certain. Although there is no single overarching policy today on mentoring, the federal government has supported multiple mentoring efforts for vulnerable youth since JUMP was discontinued in FY2003. In recent years, two mentoring programs—the Mentoring Children of Prisoners (MCP) program and Safe and Drug Free Schools (SDFS) Mentoring program—have provided a significant source of federal funding for mentoring services. However, the programs were short- lived: funding for the MCP program, carried out by the Department of Health and Human Services (HHS) since FY2003, was discontinued as of FY2011; and funding for the SDFS program, carried out by the Department of Education (ED) since FY2002, was discontinued as of FY2010. The federal government currently funds mentoring efforts through short-term grants and initiatives. Many of these grants are carried out by the Department of Justice (DOJ), which has allocated funding for multiple mentoring programs, including mentoring for certain vulnerable youth and research on mentoring. In addition, the federal government has provided funding to programs with vulnerable youth that have a strong, but not exclusive, mentoring component. Youth ChalleNGe, an educational and leadership program for at-risk youth administered by the Department of Defense, helps to engage youth in work and school, and leadership opportunities. Adult mentors assist enrolled youth with their transition from the program for at least one year. Finally, federal agencies coordinate on mentoring issues. The Federal Mentoring Council was created in 2006 to address the ways agencies can combine resources and training and technical assistance to federally administered mentoring programs, and to serve as a clearinghouse on mentoring issues for the federal government. The council has been inactive in recent years but federal agencies, including the Departments of Housing and Urban Development (HUD) and Justice, are collaborating to reconvene the council. This report begins with an overview of the purpose of mentoring, including a brief discussion on research of structured mentoring programs. The report then describes the evolution of federal policies on mentoring since the early 1990s. The report provides an overview of the federal mentoring initiatives that are currently funded. Note that additional federal programs and policies authorize funding for mentoring activities, among multiple other activities and services. These programs are not discussed in this report. The report concludes with an overview of issues that may be of interest to Congress. These issues include the limitations of research on outcomes for mentored youth, the potential need for additional mentors, grantees’ challenges in sustaining funding, and the possible discontinuation of federal mentoring funding. The Appendix includes a description of two federal mentoring programs that were funded until FY2010 and FY2011
