Moreover, this article will explore rights and obligations of all parties in payment transaction. Lastly, it will access criteria to allocate liability when a transaction initiated through a payment initiation service provider was unaut…
Inter-provider AAA and Billing of VoIP Users with Token-based Method
2007
With the increasing popularity of wireless LAN technology, providers of real-time voice over IP (VoIP) services, known as voice service providers (VSP), are asking for roaming solutions and AAA (Authentication, Authorization and Accounting) methods that allow users to use their services from any available public Internet access network. In this paper we propose an AAA and billing architecture that allows users of VSPs to have access to the Internet from wired and wireless access networks provided by both traditional carriers, such as 3G providers, and wireless local access network (WLAN) providers. We propose a token-based AAA method that allows users of VoIP services to have their VSPs as …

Smart Auctions for Autonomic Ambient Intelligence Systems
2020
The main goal of Ambient Intelligence (AmI) is to support users in their daily activities by satisfying and anticipating their needs. To achieve such goal, AmI systems rely on physical infrastructures made of heterogenous sensing devices which interact in order to exchange information and perform monitoring tasks. In such a scenario, a full achievement of AmI vision would also require the capability of the system to autonomously check the status of the infrastructure and supervise its maintenance. To this aim, in this paper, we extend some previous works in order to allow the self-management of AmI devices enabling them to directly interact with maintenance service providers. In particular,…
Reputation Management for Distributed Service-Oriented Architectures
2010
Nowadays, several network applications require that consumer nodes acquire distributed services from unknown service providers on the Internet. The main goal of consumer nodes is the selection of the best services among the huge multitude provided by the network. As basic criteria for this choice, service cost and Quality-of-Service (QoS) can be considered, provided that the underlying Service-Oriented Architecture (SOA) be augmented in order to support the declaration of this information. The correct behavior of such new SOA platforms, however, will depend on the presence of some mechanisms that allow consumer nodes to evaluate trustworthiness of service providers. This work proposes a new…
La libertà di informazione nell’era di Internet
2018
Il mercato dell’informazione e il regime della libertà di manifestazione del pensiero hanno subito ingenti mutamenti nell'era di internet, determinando fra l'altro la crisi dei media. Lo studio approfondisce i modelli attraverso i quali vengono selezionate le informazioni on line e quelli di distribuzione delle stesse ed evidenzia i rischi derivanti dalle fake news e dagli hate speach, che soffocano il "mercato delle idee" e della informazione, concludendo con una riflessione sulle possibilità di regolazione del fenomeno.
Information providers e information sharing mechanisms nel mercato creditizio italiano.
2015
Il presente lavoro esamina i principali casi aziendali di information providers e sistemi di information sharing operanti nel mercato creditizio italiano, con una prospettiva di analisi prettamente economico-aziendale. Sono analizzati i modelli di business dei primi 5 operatori italiani: Cerved, Crif, Infocamere, Experian, Euler Hermes Siac. Sarà, inoltre, preso in esame il sistema di condivisione di informazioni di natura pubblica, gestito dalla Banca d’Italia, che ha un ruolo di rilievo nel sistema creditizio italiano. Quello che emerge dall’analisi è un quadro molto variegato dei sistemi di informazione creditizia operanti in Italia in quanto, accanto al tradizionale business dell’inform…
Il cibo come mezzo per una convivenza ostipitale. Gli equilibri fragili del cotto e del crudo fra migranti e popolazione autoctona in un mercato di P…
2021
In questo articolo le ricercatrici riesaminano il concetto di ostipilità (Derrida, 2000) alla luce della cultura materiale, del cibo e delle pratiche alimentari connesse, per analizzare i collegamenti tra cibo, appartenenza e commensalità. L’osservazione partecipante e le interviste semi-strutturate di questa ricerca hanno permesso di segnare i confini del mercato di Ballarò, di individuare le tipologie di attività commerciale, fondate sul “cotto” e/o sul “crudo”, che contraddistinguono le diverse aree di mercato, come pure le forme di “convivenza armata” in atto fra autoctoni e migranti. Se il cibo cotto è ospitale a determinate condizioni, il cibo crudo ha maggiori probabilità di stabilir…
'Uber Economy': Employee, Self-Employed or a Need of a Special Employment Regulation?
2015
The Digital era has changed industrial relationships dramatically. This has caused a considerable legal uncertainty about which rules apply to cyberspace. Technology is transforming business organization in a way that makes employees -- as subordinate work -- less necessary. A new type of companies "on demand economy" "sharing economy" -- dedicated to connecting customers directly with individual service providers are emerging. Thus, these companies develop their core business completely through workers classified as self-employed. In this context, employment law is facing its greatest challenge, dealing with a very different reality compared to the one existing when it was created. This pa…
A privacy-aware framework for decentralized online social networks
2015
Online social networks based on a single service provider suffer several drawbacks, first of all the privacy issues arising from the delegation of user data to a single entity. Distributed online social networks (DOSN) have been recently proposed as an alternative solution allowing users to keep control of their private data. However, the lack of a centralized entity introduces new problems, like the need of defining proper privacy policies for data access and of guaranteeing the availability of user's data when the user disconnects from the social network. This paper introduces a privacy-aware support for DOSN enabling users to define a set of privacy policies which describe who is entitle…
