"Socioeconomic activities such as supply and distribution of gas or electricity and the Infrastructures that generate it or transport it (power plants, gas pipes), are vital to the day-to-day functioning of any country. Due to several factors, the social and financial European situation, or supply constraints, energy & utilities have become, over the last years, a prominent issue in Europe.In this light, any serious disruption on these Critical Infrastructures (producers or transporters) could have an enormous impact on the well-being of any society. How those Critical Infrastructures can anticipate any threat with the view of avoiding potential disruptions is the main goal of ARGOS project. This project proposal will enhance the capacity of those Infrastructures in order to monitor, deter, and respond to a potential threat using ‘Early Warning Technologies’.Commonly, enhancing security capabilities entails the inherent implication of ethical aspects. In this sense, the EC is highly sensitive with this matter and it’s making relevant efforts to regulate this situation. As a starting point of the project idea and with the aim of being in tune with EC efforts, ARGOS has focus on the development of non-privacy invasive technologies such as vibration sensors. Regarding technologies that might be considered as ‘non full privacy respectful’ such as audio sensors, this will not be developed with the aim of recording conversations (but for distinguish among animals, humans or machines); and others such as video sensors, will contemplate embedded video analytics for 1st level processing (together with a 2nd level of powerful video analytics placed in the local gateway) so they will transfer only metadata instead of images."
