RERUM’s digest of the IoT Forum, organised by BDigital Events

IoT Forum, Barcelona, 3rd December 2014

The data is the oil of XXI century and the IoT will help improve the quality of life of people and economic growth. We must be able, despite their maturity, to develop new innovative products and services that solve problems real for society to understand the IoT concept and see its potential.

This has been stated by most of the speakers during the second edition of IoT Forum that BDigital Technology Centre organised on the 3rd of December 2014 in Barcelona.

In the event, which brought together more than 300 professionals in the technology sector in the auditorium of Mobile World Capital Centre, speakers and attendees have agreed that the IoT will grow when a service or killer application is highly demanded by the citizens.

Through more than twenty presentations and discussions, it has drawn the IoT advances at global and regional level and has disclosed strategies, products and services that governments and companies have already implemented both in Catalonia and internationally.

According to Gartner, a massive use of the Internet of Things is expected in 10 years. Knowing these forecasts, Jordi Puigneró, General Director of Telecommunications and Information Society of the Generalitat de Catalunya, said flatly that:

Catalonia will be smart or not be. Or we put in front of transformation and surfed the wave, or we are on the beach waiting for the technological tsunami we pull over.

So he explained to the attendees the new Smart Region strategy, led by the Catalan government, to position the region as an intelligent territory of reference at European level. The initiative has two objectives: to create an intelligent industry producing technology products and services – and with it, employment in the digital economy – and to place citizens at the center of this digital strategy region. Puigneró recalled that the people are linked to the territory, but also to networks:

Facebook is the third most populous country in the world.

The IoT, catalytic smart industry

From real cases such as the Swedish multinational SKF – dedicated to the design and delivery of industrial products – Menno Van Rijn, director of Bax & Willems has shown international examples of how the industry has already implemented solutions based on IoT. Through implementations of the IoT in the automotive, aerospace, Van Rijn has referred to the changes that are occurring in business value chains, increasingly connected and smarter. This fact is resulting in devices monitored 24 hours a day, in the detection of incidents at the same time as they occur or the identification of behavioural patterns useful for predictive maintenance. He concludes:

The IoT will reduce the life cycle of all processes in the value chain of business and cause moving from a traditional mass production (from Asian countries to Europe) to production back to Europe, more localized, efficient and sustainable.

The IoT, serving the smart city

The market for Internet of Things is maturing and will gain popularity when you start talking about their real applicability

This was exposed by Albert Vidal, CEO of Effilogics, in the session From the smart smart city region, during which there were discussions on real examples of how the Internet of Things is already serving the built smart city and how this will be done in the next 5 to 10 years.

Irene Compte, from Urbiótica, showed real examples already done in the company, currently working on real projects in Europe and Latin America. Among them, a comprehensive information service on mobility in the French city of Nice. Compte explained that Urbiótica has 10,000 devices distributed worldwide in different projects and manages 1 million useful messages every hour in order to improve the management of cities.

Also, Jordi Cirera, showed the Sentilo platform as the Urban Barcelona platform for IoT data. Cirera added that anybody knows which is going to become the standard, but we have to be ready for the future one. Sentilo wants to be an open platform available for third parties.

For his part, Josep Laborda, ITS Project Manager of the RACC, has shown how technology can assist in the management of cities in the mobility area. Specifically, the app Infotransit, related to RERUM’s Use Case for traffic management, allows the status of traffic as the number of connected cars that are circulating. Laborda pointed out the need for objects to be connected not only to their provider, but also to the managers of transit. That is how different companies and agencies shall cooperate to provide more useful and commercial services.

From another perspective, Alessandro Bassi from Bassi Consulting introduced in his keynote speech that the IoT is not only technology and that it will arrive to all layers of our societies, from the technology to the social perspective and how cooperative business can be more powerful with IoT services and products.

The citizen, star of smart cities

The discussions generated from the various conferences have revealed that the citizen must be the protagonist in the construction of digital cities, to avoid, according to Josuè Sallent, director of Barkeno Advisors, having only sensorized cities. Sallent explained that some projects implemented internationally have had to be canceled because of complaints from citizens who have stated that the proposed services went against privacy and intimacy. Precisely that’s the reason why in RERUM privacy is a key point of research, in order to offer tools that can protect citizen privacy in spite of having thousands or millions of sensors surrounding us in future Smart Cities.

In general, all speakers agreed that the benefit provided to citizens and perceived by them to be the center of any project based on the IoT and that both companies and agencies should evaluate the return on investment (efficiency, transparency, etc.) before they run any proposal.

All the keynotes and panel discussions (some of them only in Catalan and/or Spanish) are available here.

Smart City Expo and World Congress, Nov. 2014, Barcelona – Some clues


Cities are where people live!

This was the opening statement made by Francisco Jariego, Director of Industrial Internet of Things (IoT), during the Smart City Expo & World Congress hosted in Barcelona, 2014.  Citizen’s needs are the ones paving the road to deploy the future Smart Cities, with infrastructure fitted to adapt to its citizen needs, configurable to enrich the set of services it can provide, as pointed out David Johera, Commercial Director of Wonderware, cities should be envisioned as a resource, changeable to adapt and react to its present landscape and citizen requirements, for example to adapt the garbage collection schedule on a given area, manage its water irrigation network to avoid wasting water, build mobility ecosystems and route traffic efficiently: improve the city quality life.

But Cities have also the obligation to become smarter in order to be efficient, as pointed by Michael Jansen from Cityzenith, a city needs to share its own resources and information, and effectively use the collected data and transform it into useful and comprehensive information, easily shareable between government entities and even with its citizens, to improve the strategies and decisions towards enforcing policies that enrich the City itself.

In any case targeting citizen needs also means dealing with citizen’s concerns, such as privacy and security. Nowadays, with the increasing number of smart-phones and people-driven applications, not all information sources are hardware: people, inadvertently or willingly, are sensors too.  IoT is not new to the industrial world; not so many years ago the lack of standards was a problem on how to integrate networks and services safely and securely. Now, even with the market driving the standardization efforts, the problem is still there, augmented by the proliferation of IoT applications, products and platforms, which has brought into our houses connected toothbrushes, air quality sensors, smart wearables and smart appliances … and Cities now investing in ubiquitously collecting data from our surroundings.  This opens more questions on the privacy and security of the data users, willingly or inadvertently, share while platforms and services are fragmented into isolated silos, governed by its own standards.

Still lot of work to do, so, but fortunately the RERUM project is progressing specifically in the privacy and security part, towards to an open and standard-based middleware that will cover this need very soon … stay tuned.

Initial real world trial discussion with Tarragona city representatives

On 29 September RERUM project experts met with the representatives of the Spanish city of Tarragona to kick-start the preparation for the validation process of the RERUM solution through real world trials. The discussions focused on various options for implementing the planned trials in Tarragona. 4 trials are planned in total, encompassing both outdoor and indoor use cases of smart transportation, environment monitoring, home energy management and comfort quality monitoring. The discussion with ICT smart city projects of the city of Tarragona covered the initial steps necessary to be completed, logistic aspects around the trials, overall responsibilities, and associated ethical aspects and how to deal with them. The deputy mayor of the city also attended a significant part of the meeting.


Representatives of the city of Tarragona, Spain, including the deputy mayor, and RERUM project experts

RERUM plans that this initial meeeting will be followed up with a sequence of meetings involving also the identified key local players whose collaboration is essential.

RERUM demo in FORTH’s Marie Curie Open Day

On July 3rd 2014 a “Marie Curie Open Day” was organised at the premises of FORTH in Heraklion, Greece. The event was organised as part of the dissemination and publicity activities of the Marie Curie projects MESH-WISE and SOrBet. The event was split into two parts, one with invited tutorials and one with demonstrations.

RERUM was invited to participate in the event and show a demo to the attendees. Dr. Alexandros Fragkiadakis presented the demo “Compressive Sensing based gathering of temperature measurements from sensor devices”. The idea of the demo is to show the implementation of a mechanism for jointly compressing and encrypting measurements using Compressive Sensing on the Zolertia Z1 devices. In this respect, the transmitted measurements are simultaneously compressed and encrypted with a single key, using a lightweight mechanism that runs on the devices. In the figure below you can see Dr. Fragkiadakis presenting the demo.

In the TV screen three charts are depicted. The top chart shows the actual real time temperature data that are gathered from the devices. The middle chart shows the reconstructed (decompressed and decrypted) measurements at the server. The low chart shows the reconstruction error which is much less than 1% in our case. We  have to note here that we used a 50% compression, which means that we sent 50% less measurements, which reduces significantly the energy consumption on the sensor device.



RERUM’s 4th Plenary Meeting

RERUM’s 4th meeting took place at FORTH in Heraklion at the end of June and beginning of July, with a very strong attendance from all partners. The three days of the meeting were packed with very fruitful and interesting discussions!

At the end of day three the partners of RERUM connected with 2 other EU projects related with Smart Cities (MESH-WISE / SOrBet) in a joint session. The goal was to identify common areas between the three projects and possibilities for cooperation.

RERUM identified itself as able to provide the other projects with guidelines on how to build more secure and privacy preserving architectures. MESH-WISE presented itself as a promising solution for providing optimized performance in wireless mesh networking within urban areas that could possibly help RERUM in the lower layers networking solutions. SOrBet proposed to assist RERUM in the area of building automation systems and in the trials, since the SOrBet partners have an existing automation system that can be used.

In general, the three projects have identified common areas and will continue the close cooperation in the future.

RERUM @ ACNS 2014 in Lusanne

RERUM will be present at the ACNS conference. Henrich Pöhls will attend the 12th International Conference on Applied Cryptography and Network Security taking place from 10th of June till 13th of June in Lausanne (Swiss) and present results from RERUM.

He will present the paper ‘On Updatable Redactable Signatures’ authored by H. C. Pöhls and K. Samelin in a presentation on Friday 13th of June.

The paper is about so called redactable signatures, which allow removing parts from signed documents. In RERUM we gathered the state-of-the-art of malleable signature schemes and our analysis of security models revealed that the existing models do not capture the possibility that the signer can “update” signatures, i.e., add new elements. Neglecting this in the model, the models would tolerate that third parties can generate forgeries if they are given access to an update oracle. Moreover, the analysis showed that there are constructions which permit creating a signature by merging two redacted messages, if they stem from the same original. Again the short coming of previous models is that this is not explicitly described. The paper presents an adjusted definition that captures both possibilities. Moreover, the paper presents a provably secure construction in the standard model, which makes use of a novel trapdoor-accumulator.
