Location Proof

Smart devices have accentuated the importance of geolocation information. Geolocation identification using smart devices has paved the path for incentive-based location-based services (LBS). However, a user’s full control over a smart device can allow tampering of the location proof. Witness-oriented location proof systems (LPS) have emerged to resist the generation of false proofs and mitigate collusion attacks. However, witness-oriented LPS are still susceptible to three-way collusion attacks (involving the user, location authority, and the witness). To overcome the threat of three-way collusion in existing schemes, we introduce a decentralized consensus protocol called MobChain in this paper. In this scheme the selection of a witness and location authority is achieved through a distributed consensus of nodes in an underlying P2P network that establishes a private blockchain. The persistent provenance data over the blockchain provides strong security guarantees; as a result, the forging and manipulation of location becomes impractical. MobChain provides secure location provenance architecture, relying on decentralized decision making for the selection of participants of the protocol thereby addressing the three-way collusion problem. Our prototype implementation and comparison with the state-of-the-art solutions show that MobChain is computationally efficient and highly available while improving the security of LPS.

This paper draws on work conducted under the Joint Information Systems Committee (JISC) User Behaviour Monitoring and Evaluation Framework to identify a range of issues associated with research design that can form a platform for enquiry about knowledge creation in the arena of user behaviour. The Framework has developed a multidimensional set of tools for profiling, monitoring and evaluating user behaviour. The Framework has two main approaches: one, a broad-based survey which generates both a qualitative and a quantitative profile of user behaviour, and the other a longitudinal qualitative study of user behaviour that (in addition to providing in-depth insights) is the basis for the development of the EIS (Electronic Information Services) Diagnostic Toolkit. The strengths and weaknesses of the Framework approach are evaluated. In the context of profiling user behaviour, key methodological concerns relate to: representativeness, sampling and access, the selection of appropriate measures and the interpretation of those measures. Qualitative approaches are used to generate detailed insights. These include detailed narratives, case study analysis and gap analysis. The messages from this qualitative analysis do not lend themselves to simple summarization. One approach that has been employed to capture and interpret these messages is the development of the EIS Diagnostic Toolkit. This toolkit can be used to assess and monitor an institution's progress with embedding EIS into learning processes. Finally, consideration must be given to integration of insights generated through different strands within the Framework.DOI:10.1080/0968776030110104

Location based services (LBS) are considered by some to be the ‘golden child” of wireless data services and one of the few areas where users would be willing to pay a premium for usage. Mobile Operators however are yet to be convinced, and despite acknowledging location services as strategic, have not considered it a priority. Recent LBS deployments however focusing on a holistic view of user behaviour are showing positive signs of success. These deployments focus on providing services that integrate different content from multiple sources to provide users with a coherent and logically connected flow of application options. These applications are called “Find it, Route it, Share it & Buy it. Importantly this model maximises return on investment (ROI) by motivating user to undertake multiple transactions. The challenge for those within the LBS industry is to convince mobile operators that LBS is viable and can deliver a strong ROI. Indeed, the future success of LBS is as much dependant on locating the money as it is about locating the subscribers.

Indoor positioning and localization have been regarded as some of the most widely researched areas during the last decade. The wide proliferation of smartphones and the availability of fast-speed internet have initiated several location-based services. Concerning the importance of precise location information, many sensors are embedded into modern smartphones. Besides Wi-Fi positioning, a rich variety of technologies have been introduced or adopted for indoor positioning such as ultrawideband, infrared, radio frequency identification, Bluetooth beacons, pedestrian dead reckoning, and magnetic field, etc. However, special emphasis is put on infrastructureless approaches like Wi-Fi and magnetic field-based positioning, as they do not require additional infrastructure. Magnetic field positioning is an attractive solution for indoors; yet lack of public benchmarks and selection of suitable benchmarks are among the big challenges. While several benchmarks have been introduced over time, the selection criteria of a benchmark are not properly defined, which leads to positioning results that lack generalization. This study aims at analyzing various public benchmarks for magnetic field positioning and highlights their pros and cons for evaluation positioning algorithms. The concept of DUST (device, user, space, time) and DOWTS (dynamicity, orientation, walk, trajectory, and sensor fusion) is introduced which divides the characteristics of the magnetic field dataset into basic and advanced groups and discusses the publicly available datasets accordingly.

Abstract Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

SummaryA routine has been developed for the processing of the 5820 plates of the survey. The plates are measured on the automatic measuring machine, GALAXY, and the measures are subsequently processed by computer, to edit and then refer them to the SAO catalogue. A start has been made on measuring the plates, but the final selection of stars to be made is still a matter for discussion.

Scanning Electron

Ultimate resolution in the scanning electron microscope is determined not only by the diameter of the incident electron beam, but by interaction of that beam with the specimen material. Generally, while minimum beam diameter diminishes with increasing voltage, due to the reduced effect of aberration component and magnetic interference, the excited volume within the sample increases with electron energy. Thus, for any given material and imaging signal, there is an optimum volt age to achieve best resolution.In the case of organic materials, which are in general of low density and electric ally non-conducting; and may in addition be susceptible to radiation and heat damage, the selection of correct operating parameters is extremely critical and is achiev ed by interative adjustment.
