e-Profile Management as a Basic Horizontal Service for the Creation of Specialized e-Services Maria Chiara Pettenati, Franco Pirri, Dino Giuli Electronics and Telecommunications Department, University of Florence [mariachiara.pettenati, franco.pirri, dino.giuli]@unifi.it Integrating raw data with the Web, i.e. making a Web of Data, has the intrinsic power to create maximum utility for the Netizens. However current technical approaches in this direction fail in handling properties such as data provenance and licensing, thus increasing the chasm between the trend to “open data for maximum reuse” and the security and privacy needs related to users’ personal data (e-Profile) treatment. In such a context a specific challenge is the development of innovative and alternative approaches for e-Profiles creation and management. The InterDataNet architecture is herewith considered as infrastructural solution aiming at providing a Web-based trust-enabling management of e-Profiles to third party generic e-Service Providers to support access and delivery of trusted and personalized e-Services. This paper presents some flashes of a more detailed analysis in progress on this problem, made according to the multiplicity of the Service Science, Management and Engineering perspectives, to highlight the prospected advantages and the viability involved by the proposed approach. 1. Introduction Information guides our behavior and decisions. We live in an age in which the essential raw material is information; i.e. data with a context. Handling distributed granular information and its context via the Web, in such a way that it can ground the development of e-Services is a cornerstone in the development of science fields related to the Web Science (webscience.org/home.html). The pervasive fruition of e- Services in several domains of human’s life, ranging from information communication and culture, citizenship, social relations, finance, commerce, mobility, education, working, entertainment, assistance, emergency, etc. inevitably involves a significant management of personal digital information, also referred to as user profiles or e-Profiles. In this paper we address the creation and management of e- Profiles as basic global – i.e. Web-wide - e-Service. The e-Profile basic service is conceived as a horizontal service handled by a network of e-Profile Service Providers (e-PSP), which can be made commonly shareable and accessible by heterogeneous e- Services delivered by third party Service Providers supporting the effective and trust- enabling management of users-digital identities, while guaranteeing consistence and
