Knowing Your Population: Privacy-Sensitive Mining of Massive Data
Location and mobility patterns of individuals are important to environmental
planning, societal resilience, public health, and a host of commercial
applications. Mining telecommunication traffic and transactions data for such
purposes is controversial, in particular raising issues of privacy. However,
our hypothesis is that privacy-sensitive uses are possible and often beneficial
enough to warrant considerable research and development efforts. Our work
contends that peoples behavior can yield patterns of both significant
commercial, and research, value. For such purposes, methods and algorithms for
mining telecommunication data to extract commonly used routes and locations,
articulated through time-geographical constructs, are described in a case study
within the area of transportation planning and analysis. From the outset, these
were designed to balance the privacy of subscribers and the added value of
mobility patterns derived from their mobile communication traffic and
transactions data. Our work directly contrasts the current, commonly held
notion that value can only be added to services by directly monitoring the
behavior of individuals, such as in current attempts at location-based
services. We position our work within relevant legal frameworks for privacy and
data protection, and show that our methods comply with such requirements and
also follow best-practice
Security in transnational interoperable PPDR communications: threats and requirements
The relevance of cross border security operations
has been identified as a priority at European level for a long time.
A European network where Public Protection and Disaster Relief
(PPDR) forces share communications processes and a legal
framework would greatly enforce response to disaster recovery
and security against crime. Nevertheless, uncertainty on costs,
timescale and functionalities have slowed down the
interconnection of PPDR networks across countries and limited
the transnational cooperation of their PPDR forces so far. In this
context, the European research project ISITEP is aimed at
developing the legal, operational and technical framework to
achieve a cost effective solution for PPDR interoperability across
European countries. Inter alia, ISITEP project is specifying a
new Inter-System-Interface (ISI) interface for the
interconnection of current TETRA and TETRAPOL networks
that can be deployed over Internet Protocol (IP) connectivity.
This approach turns communications security as a central aspect
to consider when deploying the new IP ISI protocol between
PPDR national networks. Ensuring that threats to the
interconnected communications systems and terminals are
sufficiently and appropriately reduced by technical, procedural
and environmental countermeasures is vital to realise the trusted
and secure communication system needed for the pursued PPDR
transnational cooperation activities. In this context, this paper
describes the framework and methodology defined to carry out
the development of the security requirements and provides a
discussion on the undertaken security risk and vulnerability
analysis.Peer ReviewedPostprint (author's final draft
Privacy in (mobile) telecommunications services
Telecommunications services are for long subject to privacy regulations. At stake are traditionally: privacy of the communication and the protection of traffic data. Privacy of the communication is legally founded. Traffic data subsume under the notion of data protection and are central in the discussion.
The telecommunications environment is profoundly changing. The traditionally closed markets with closed networks change into an open market with open networks. Within these open networks more privacy sensitive data are generated and have to be exchanged between growing numbers of parties. Also telecommunications and computer networks are rapidly being integrated and thus the distinction between telephony and computing disappears. Traditional telecommunications privacy regulations are revised to cover internet applications.
In this paper telecommunications issues are recalled to aid the on-going debate.
Cellular mobile phones have recently be introduced. Cellular networks process a particular category of traffic data namely location data, thereby introducing the issue of territorial privacy into the telecommunications domain. Location data are bound to be used for pervasive future services. Designs for future services are discussed and evaluated for their impact on privacy protection.</p
The Critical Challenges from International High-Tech and Computer-Related Crime at the Millennium
The automotive industry stands in front of a great challenge, to decrease its impact on the environment. One important part in succeeding with this is to decrease the structural weight of the body structure and by that the fuel consumption or the required battery power. Carbon fibre composites are by many seen as the only real option when traditional engineering materials are running out of potential for further weight reduction. However, the automotive industry lacks experience working with structural composites and the methods for high volume composite manufacturing are immature. The development of a composite automotive body structure, therefore, needs methods to support and guide the conceptual work to improve the financial and technical results. In this thesis a framework is presented which will provide guidelines for the conceptual phase of the development of an automotive body structure. The framework follows two main paths, one to strive for the ideal material diversity, which also defines an initial partition of the body structure based on the process and material selection. Secondly, a further analysis of the structures are made to evaluate if a more cost and weight efficient solution can be found by a more differential design and by that define the ideal part size. In the case and parameter studies performed, different carbon fibre composite material systems and processes are compared and evaluated. The results show that high performance material system with continuous fibres becomes both more cost and performance effective compared to industrialised discontinuous fibre composites. But also that cycle times, sometimes, are less important than a competitive feedstock cost for a manufacturing process. When further analysing the manufacturing design of the structures it is seen that further partition(s) can become cost effective if the size and complexity is large enough. Â Â Â QC 20140527</p
Privacy matters:issues within mechatronics
As mechatronic devices and components become increasingly integrated with and within wider systems concepts such as Cyber-Physical Systems and the Internet of Things, designer engineers are faced with new sets of challenges in areas such as privacy. The paper looks at the current, and potential future, of privacy legislation, regulations and standards and considers how these are likely to impact on the way in which mechatronics is perceived and viewed. The emphasis is not therefore on technical issues, though these are brought into consideration where relevant, but on the soft, or human centred, issues associated with achieving user privacy
