An Architecture to Support the Collection of Big Data in the Internet of Things

International audienceThe Internet of Things (IoT) relies on physical objects interconnected between each others, creating a mesh of devices producing information. In this context, sensors are surrounding our environment (e.g., cars, buildings, smartphones) and continuously collect data about our living environment. Thus, the IoT is a prototypical example of Big Data. The contribution of this paper is to define a software architecture supporting the collection of sensor-based data in the context of the IoT. The architecture goes from the physical dimension of sensors to the storage of data in a cloud-based system. It supports Big Data research effort as its instantiation supports a user while collecting data from the IoT for experimental or production purposes. The results are instantiated and validated on a project named SMARTCAMPUS, which aims to equip the SophiaTech campus with sensors to build innovative applications that supports end-users

WEB service interfaces for inter-organisational business processes an infrastructure for automated reconciliation

For the majority of front-end e-business systems, the assumption of a coherent and homogeneous set of interfaces is highly unrealistic. Problems start in the back-end, with systems characterised by a heterogeneous mix of applications and business processes. Integration can be complex and expensive, as systems evolve more in accordance with business needs than with technical architectures. E-business systems are faced with the challenge to give a coherent image of a diversified reality. Web services make business interfaces more efficient, but effectiveness is a business requirement of at least comparable importance. We propose a technique for automatic reconciliation of the Web service interfaces involved in inter-organisational business processes. The working assumption is that the Web service front-end of each company is represented by a set of WSDL and WSCL interfaces. The result of our reconciliation method is a common interface that all the parties can effectively enforce. Indications are also given on ways to adapt individual interfaces to the common one. The technique was embodied in a prototype that we also present

Data Trading Similarity Signature An Extended Data Trading Framework for Human and Non-Human Actors

Fair and secure data trading is one of the most prominent challenges of the 21st century. This paper presents a second iteration of an approach to develop a data marketplace concept by checking consumer requirements. The main problem we identified is data quality and the question: Would a dataset fulfill the consumer requirements? Starting from an approach that uses a binary response set to answer the question of whether requirements are met, we concluded that a description of consumer requirements needs to be quantitatively comparable. The novel approach presented here identifies similarities between datasets and consumer requirements. It forms a unique, fingerprint-like similarity signature for each dataset, which can be interpreted by both human and non-human actors. The approach is deducted and designed by using the Design Science Research Methodology and discussed critically in the end

New Approach meets new economy: Enforcing EU product safety in e-commerce

This article reviews recent regulatory initiatives in the area of EU product safety legislation and market surveillance from the angle of e-commerce through online marketplaces. With the arrival of the internet, the sale of non-compliant and illegal consumer products has proliferated. E-commerce and globalized supply chains are challenging a regulatory system that is fragmented, highly technical and slow to respond to the dynamic changes introduced to the marketplace. The EU Commission’s 2017 notice on the surveillance of products sold online and its latest proposal for a new regulation on enforcing product compliance rules testify to the unsatisfactory state of progress in this area. A reason for this may be seen in the history and nature of New Approach style product law, which outsources technical product regulation to the industry and entrusts enforcement tightly in the hands of specialized national regulators. New actors in the supply chain, such as fulfilment service providers or e-commerce platforms, have fallen between the cracks. This article argues that extending the principles of the New Approach to e-commerce marketplaces, by seeing their activities as affecting essential requirements, could be of interest to both the problems at hand and the wider debate on online platforms regulation
