The application of data analysis techniques over large data collections provides great benefits, from personal, to business, research, and social domains. The continuous evolution of ICT is enabling the realization of such data-driven innovations at a fast pace, towards the realization of digital data markets supporting collaborative data sharing and analytics. A clear obstacle towards the realization of such potential and vision is represented by security and privacy concerns. Indeed, the (actual or perceived) loss of control over data and potential compromise of their confidentiality, also protected by privacy regulations, can have a strong detrimental impact on the realization of an open framework for enabling the sharing of information from multiple independent data owners.
The goal of MOSAICrOWN is to enable data sharing and collaborative analytics in multi-owner scenarios in a privacy-preserving way, ensuring proper protection of private/sensitive/confidential information. MOSAICrOWN has provided effective and deployable solutions allowing data owners to maintain control on the data sharing process, enabling selective and sanitized disclosure providing for efficient and scalable privacy-aware collaborative computations.
The practical objectives that MOSAICrOWN has pursued are as follows.
Objective 1 – Rich support of requirements, considering different aspects of protection and needs from different parties (data owners, as well as data subjects and privacy regulations) and addressing their satisfaction under different scenarios and threat models.
Objective 2 – Data governance framework, empowering owners with control on their data, enabling them to specify policies regulating protection of information and its selective disclosure in collaborative data platforms.
Objective 3 – Data wrapping, for supporting selective release, storage and analytics on data in the collaborative platform, while preventing (or limiting) access to the actual data content by other parties.
Objective 4 – Data sanitization, for enforcing privacy/confidentiality restrictions by producing information for the data market, or within the data market, while protecting the precise values in the original data sources.
Objective 5 – Effective exploitation, in real operational environments, demonstrating the applicability and flexibility of the project’s innovations and actual impact.
MOSAICrOWN has met all the objectives above by considering use cases providing rich and comprehensive requirements corresponding to real problems and market strategies of major players.
