Authentication of Subjects and Devices Using Biometrics and Identity Management Systems for Persuasive Mobile Computing: A Survey Paper

With the advances in Information Technology (IT) there has been an increase in threats to the communication systems and its assets. One of the most important issues of all IP networks that integrate wireless and wired technologies is the applicability and performance of the electronic identification and authentication methods. These schemes employ a variety of technologies of different degrees of security. Biometrics technology nowadays is typically considered a security necessity, tightly coupled with the foundation of highly secure identification and authentication solutions. This article provides a short survey on different types of authentication and identity management systems. It attempts to describe a summary of related works including some of the latest schemes in face and fingerprint recognition. With a better understanding of electronic authentication techniques any organization can properly select and utilize the technologies which meet its needs

Planning of Personal Area Network (II)

Personal area network (PAN) is a computer network used for communication among computer devices which including telephones and personal digital assistants close to one person. The devices mayor may not belong to the person. Its range is typically a few meters. It is used for intrapersonal communication, connecting higher level network and the internet [I]. Personal area networks can be wired with computer buses such as USB and FireWire. A wireless personal area network (WPAN) can also be made possible with network technologies such as IrDA, Bluetooth, UWB, Z-Wave and ZigBee. The different technologies are explained below

Hardware Evaluation of Near Field Magnetic Induction Communication systems

This paper examines the performance of magnetic induction communication systems for body area networks. First a theoretical study, examination and investigation of the properties and capabilities of near field magnetic induction communications as an emerging form of short range telecommunications access is given. From both a theoretical and hardware tests, results are correlated showing strong agreement between theory and hardware implementation. It is shown that power decay follows an inverse law of distance to power 6 and that certain structures in the communication terrain can affect the magnetic flux created by the transmitter from reaching the receiver thus limiting the range of communications. A body area network of the devices is shown in which a centralised hub aggregates data from the nodes before accessing a wide area network of choic

CLICK-IT: Interactive Television For Sports Action Replay

CLICK-IT (CSIRO Laboratory for Imaging by Content and Knowledge-Interactive Television) is a PC-based system which provides the user with an intelligent highlighter pen for sports action replay. It is intended as a truly interactive improvement on the drawing pad technology currently used for video annotation in sports broadcasting. The system uses computer vision techniques to focus attention and track particular objects, e.g. player(s) or ball, and semiautomatically annotate the dynamic scene. This paper describes the system including the user interface, the tracking technology based on colour and motion information, and system performance evaluation in applications to running rugby league football, basketball and socce

Characteristics Of The Magnetic Bubble 'Cone Of Silence' In Near-Field Magnetic Induction Communications

This paper introduces the concept of bubble factors for assessing the communication bubble created by a near-field magnetic induction (NFMI) communication system. First, the coupling coefficient as a function of distance between two magnetic transmitters is derived and used to show that the induced magnetic field reduces in proportion to the inverse sixth power of distance. This idea is used to define and analyse the communication bubble around the source. Three bubble factors are defined and shown to provide the best approach for quantifying the cone of silence around the transmitter and receiver. The decaying power based on the distance-bubble factor and receiver-load-bubble- factor shows that the transmitted power reduces by 60.25 dB/m. This provides the basis for receiver design and the distance at which interception of the NFMI communication is most secure
