Abstract
The Internet of Things has revolutionized the way we can think about sales and customer relationship management strategies. In this context, a view of the world where technology is embedded in practically all objects and physical spaces will be an expectable reality. This reality opens up unprecedented opportunities with regard to the levels of customization in the sales process, whether in virtual spaces or in physical spaces. However, IoT also poses enormous challenges in the field of security and in particular in the field of user privacy. In this context, this article, after analyzing some of the main challenges for IoT in the privacy domain and what impact the IoT may have in the business domain and in particular in the subdomains of sales and advertising, presents a conceptual model to support customer empowerment while citizen with regard to the definition and management of privacy policies concerns a context that may go beyond the boundaries of citizenship and be applied in scenarios without borders, whenever there is the possibility of defining policies and legislation above Country. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The common link between digital marketing definitions is the use of tools, namely online tools. One of the biggest changes in human interaction is the recent proliferation of online social networks. Rapid growth of Web-based platforms that facilitate online social behavior has significantly modified the nature of human activities, habitats, and interactions. Real-world social relationships have been migrated to the virtual world, resulting in online communities that bring people together from across the globe. This study aims to identify and describe the various digital marketing tools and which of these can be used to increase the SMEs competitiveness. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
Regional museums are relatively recent museum structures that emerged in the late 19th century after universal exhibitions. They are museums specifically dedicated to the representation of a given population in a specific territorial context, highlighting the fundamental traits that characterize the nature and essence of that community, differentiating it from others. In northern Portugal, law no. 125/97, created the Douro Museum, a territory museum that represents the natural and cultural heritage of the demarcated Douro region, the first demarcated and regulated region of the world, in 1756, by Marques de Pombal, extending over an area of of 250,000 ha, between Barqueiros and Barca d’Alva along the Douro River and its tributaries. The museum has a “polynuclear structure distributed throughout the Douro region, based in Peso da Régua” (art. 2), serving as an element for mobilizing tourists, mainly through its main temporary exhibitions, videos, etc. In an information society, characterized by the empowerment of citizens with regard to their ability to independently obtain information and, in the process, to leave their footprint, it is crucial to understand and anticipate their interests. In this way, the supply and responsiveness of tourism agents and regional actors will be increased, making them better able to decide for an offer better suited to the real interests of visitors and even enable to influence them. This article aims to know the profile of tourists/consumers through their online behavior, trying to understand what kind of information they are looking for, which keywords are most used and searched using the fundamentals of Data Analytics and using the Google Trends tool. Moreover, this study enables to better understand the connection between online search interests and the reality of the Douro Museum visitants. This approach is nowadays a major contribute to bridge the gap between visitors needs/interests and tourism player’s strategies definition, making Data Analytics a fundamental tool to enable decision support systems. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
The evolution of technology in the last decade predicts a future where technology is disseminated in the environment in order to merge with the environment itself, being omnipresent. This world paradigm has been associated with the Internet of Things concept or, according to several authors, with the Internet of Everything concept. The potential massive dispersion of technology, which, with the progress of nanotechnology, will be increasingly miniaturized, combined with high-performance and universal communication networks, will revolutionize the concept of monitoring, resulting in profound changes in various sectors of activity and knowledge. In this context, this article presents a cloud-based Internet of Things architecture in order to respond to the growing needs of monitoring by the Civil Protection Public Organizations, who are responsible for monitoring several parameters and produce multiple information and reports in the context of the security of populations and territories. Finally, it is presented a prototype implemented according to the proposed architecture capable of monitoring monoliths dispersed in the territory, as a way of acting preventively, avoiding merely reactive actions after disaster situations. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
The economic sector of tourism has gained significant weight in the economy of many countries, highlighting the weight of this sector in Portugal. However, the inconsistency and seasonality of demand causes companies linked to the sector to encounter difficulties regarding the planning and management of resources allocated to the activity. It is often the case that there are periods of economic loss caused by a small volume of demand that is insufficient to support the costs of the activity. In this context, this article proposes a system that, based on intelligent data analysis, allows a hotel chain to segment customers and enhance exclusive offers to minimize fluctuation and demand gaps in hotel units installed in thermal instances.
