Abstract
Data sharing presents extensive opportunities and challenges in domains such as the public sector, health care and financial services. This paper introduces the concept of "trusted data marketplaces" as a mechanism for enabling trusted sharing of data. It takes credit scoring-an essential mechanism of the entire world-economic environment, determining access for companies and individuals to credit and the terms under which credit is provisioned-as an example for the realization of the trusted data marketplaces concept. This paper looks at credit scoring from a data perspective, analyzing current shortcomings in the use and sharing of data for credit scoring, and outlining a conceptual framework in terms of a trusted data marketplace to overcome the identified shortcomings. The contribution of this paper is two-fold: (1) identify and discuss the core data issues that hinder innovation in credit scoring; (2) propose a conceptual architecture for trusted data marketplaces for credit scoring in order to serve as a reference architecture for the implementation of future credit scoring systems. The architecture is generic and can be adopted in other domains where data sharing is of high relevance.
