Faculty of Informatics - Papers (Archive)
Location-based services (LBS) are those applications that utilize the position of an end-user, animal or thing based on a given device (handheld, wearable, interwoven into fabric or implanted), executed for a particular purpose. LBS applications range from those that are mission-critical to those that are used for convenience, from those that are mandatory to those that are voluntary, from those that are targeted at the mass market to those that cater for the needs of a niche market. Location services can be implemented using a variety of access mediums including global positioning systems and radio-frequency identification, rendering approximate or precise …
Secure Transmission Of Shared Electronic Health Records: A Review, Rachel J. Mahncke, Patricia A. Williams
Secure Transmission Of Shared Electronic Health Records: A Review, Rachel J. Mahncke, Patricia A. Williams
Australian Information Security Management Conference
Paperbased health records together with electronic Patient Management Systems remain the norm for hospitals and primary care practices to manage patient health information in Australia. Although the benefits of recording patient health information into an electronic format known as an electronic health record (EHR) are well documented, the use of these systems has not yet been fully realised. The next advancement for EHRs is the ability to share health records for the primary purpose of improved patient care. This may for example enable a primary care physician, with the patient’s consent, to electronically share pertinent health information with a specialist, …

Cyber Crime And Biometric Authentication – The Problem Of Privacy Versus Protection Of Business Assets, Michael G. Crowley
Australian Information Security Management Conference
Cyber crime is now a well recognised international problem that is a major issue for anyone who runs, manages, owns, uses or accesses computer systems linked to the worldwide web. Computer systems are business assets. Personal biometric information is also an asset. Studies have shown that privacy concerns represent a key hurdle to the successful introduction of biometric authentication. In addition, terrorist activity and the resultant legislation have added an additional risk factor businesses need to take into account if they propose using biometric authentication technology. This paper explores the use of biometric authentication to protect business and individual assets. …

Does Your Wireless Lan Have Criminal Intent?, Michael Crowley, Andrew Woodward
Australian Information Security Management Conference
All of the literature relating to wireless network security has focused on the flaws, newer alternatives and suggestions for securing the network. There is much speculation and anecdotal statements in relation to what can happen if a breach occurs, but this is mostly from a computer security perspective, and mostly expressed in terms of potential for financial loss. This paper examines the potential legal ramifications of failing to properly secure a wireless network. Several scenarios are examined within based on usage of wireless on the various category of attack. Legal opinion, backed up with case law, is provided for each …
Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams
Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams
Australian Information Security Management Conference
In the medical field, information security is an important yet vastly underrated issue. Research into the protection of sensitive medical data is often technically focused and does not address information systems and behavioural aspects integral to effective information security implementation. Current information security policy and guidelines are strategically oriented which, whilst relevant to large organisations, are less supportive to smaller enterprises such as primary care practices. Further, the conservative nature of the medical profession has been shown to hinder investigation into information technology use and management, making effective improvement based on research problematical. It is an environment which relies greatly …

Worldwide Interoperability for Microwave Access (WiMAX) is going to be an emerging wireless technology for the future. With the increasing popularity of Broadband internet, wireless networking market is thriving. Wireless network is not fully secure due to rapid release of new technologies, market competition and lack of physical infrastructure. In the IEEE 802.11 technology, security was added later. Iin IEEE 802.16, security has been considered as the main issue during the design of the protocol. However, security mechanism of the IEEE 802.16 (WiMAX) still remains a question. WiMAX is relatively a new technology; not deployed widely to justify the evidence …
Mapping The Consensual Knowledge Of Security Risk Management Experts, David J. Brooks
Mapping The Consensual Knowledge Of Security Risk Management Experts, David J. Brooks
Australian Information Warfare and Security Conference
The security industry comprises of diverse and multidisciplined practitioners, originating from many disciplines. It has been suggested that the industry has an undefined knowledge structure, although security experts contain a rich knowledge structure. There has also been limited research mapping security expert knowledge structure, reducing the ability of tertiary educators to provide industry focused teaching and learning. The study utilized multidimensional scaling (MDS) and expert interviews to map the consensual knowledge structure of security experts in their understanding of security risk. Security risk concepts were extracted and critiqued from West Australian university courses. Linguistic analysis categorised the more utilized security …

Scalability In A Secure Distributed Proof System, Kazuhiro Minami, David Kotz
Scalability In A Secure Distributed Proof System, Kazuhiro Minami, David Kotz
Dartmouth Scholarship
A logic-based language is often adopted in systems for pervasive computing, because it provides a convenient way to define rules that change the behavior of the systems dynamically. Those systems might define rules that refer to the users' context information to provide context-aware services. For example, a smart-home application could define rules referring to the location of a user to control the light of a house automatically. In general, the context information is maintained in different administrative domains, and it is, therefore, desirable to construct a proof in a distributed way while preserving each domain's confidentiality policies. In this paper, …
Electronic Records Management Criteria And Information Security, A Shaw, David T. Shaw
Electronic Records Management Criteria And Information Security, A Shaw, David T. Shaw
Australian Information Warfare and Security Conference
Records management practices are mandatory in many business and government operations. Records management is a mature discipline with extensive body of knowledge, professional associations and clearly defined Australian and international standards. Records systems encompass the hardware, software and people necessary for operation and include records generated by and for the system. The Australian legal system has clearly defined standards for admissible evidence in the Evidence Act. Relevant records may require substantial preparation for submission and yet be inadmissible in legal proceedings. The records and system may be challenged in both theoretical and practical senses and appropriate practices and associated records …

Networks are growing in popularity, as wireless communication hardware, both fixed and mobile, becomes more common and affordable. The Monash Suburban Ad-Hoc Network (SAHN) project has devised a system that provides a highly secure and survivable ad-hoc network, capable of delivering broadband speeds to co-operating users within a fixed environment, such as a residential neighbourhood, or a campus. The SAHN can be used by residents within a community to exchange information, to share access to the Internet, providing last-mile access, or for local telephony and video conferencing. SAHN nodes are designed to be self-configuring and selfmanaging, relying on no experienced …
Channel Sampling Strategies For Monitoring Wireless Networks, Udayan Deshpande, Tristan Henderson, David Kotz
Channel Sampling Strategies For Monitoring Wireless Networks, Udayan Deshpande, Tristan Henderson, David Kotz
Dartmouth Scholarship
Monitoring the activity on an IEEE 802.11 network is useful for many applications, such as network management, optimizing deployment, or detecting network attacks. Deploying wireless sniffers to monitor every access point in an enterprise network, however, may be expensive or impractical. Moreover, some applications may require the deployment of multiple sniffers to monitor the numerous channels in an 802.11 network. In this paper, we explore sampling strategies for monitoring multiple channels in 802.11b/g networks. We describe a simple sampling strategy, where each channel is observed for an equal, predetermined length of time, and consider applications where such a strategy might …

Journal of Digital Forensics, Security and Law
Recent regulations in the United States (U.S.) such as the Sarbanes-Oxley Act of 2002 require top management of a public firm to provide reasonable assurance that they institute internal controls that minimize risks over the firm’s operations and financial reporting. External auditors are required to attest to the management’s assertions over the effectiveness of those internal controls. As firms rely more on information technology (IT) in conducting business, they also become more vulnerable to IT related risks. IT is critical for initiating, recording, processing, summarizing and reporting accurate financial and non-financial data. Thus, understanding IT related risks and instituting internal …

A Key Predistribution Scheme For Sensor Networks Using Deployment Knowledge, Wenliang Du, Jing Deng, Yunghsiang S. Han, Pramod K. Varshney
Electrical Engineering and Computer Science - All Scholarship
To achieve security in wireless sensor networks, it is important to be able to encrypt messages sent among sensor nodes. Keys for encryption purposes must be agreed upon by communicating nodes. Due to resource constraints, achieving such key agreement in wireless sensor networks is non-trivial. Many key agreement schemes used in general networks, such as Diffie-Hellman and public-key based schemes, are not suitable for wireless sensor networks. Pre-distribution of secret keys for all pairs of nodes is not viable due to the large amount of memory used when the network size is large. Recently, a random key pre-distribution scheme and …

New Applications Of Modulated Digital Images In Document Security, Robert A. Lee, Patrick W. Leech, Lawrey D. Mccarthy, Gerhard F. Swiegers
Faculty of Science - Papers (Archive)
In previous work we have demonstrated that selective masking, or modulation, of digital images can be used to create documents and transparent media containing covert or optically variable, overt images. In the present work we describe new applications and techniques of such "modulated digital images" (MDI's) in document security. In particular, we demonstrate that multiple hidden images can be imperceptibly concealed within visible, host images by incorporating them as a new, half-tone, printing screen. Half-toned hidden images of this type may contain a variety of novel features that hinder unauthorized copying, including concealed multiple images, and microprinted-, color-, and various …

Collaboration Enforcement In Mobile Ad Hoc Networks, Ning Jiang
Collaboration Enforcement In Mobile Ad Hoc Networks, Ning Jiang
Electronic Theses and Dissertations
Mobile Ad hoc NETworks (MANETs) have attracted great research interest in recent years. Among many issues, lack of motivation for participating nodes to collaborate forms a major obstacle to the adoption of MANETs. Many contemporary collaboration enforcement techniques employ reputation mechanisms for nodes to avoid and penalize malicious participants. Reputation information is propagated among participants and updated based on complicated trust relationships to thwart false accusation of benign nodes. The aforementioned strategy suffers from low scalability and is likely to be exploited by adversaries. To address these problems, we first propose a finite state model. With this technique, no reputation …
