Architecture to Manage and Protect Personal Data Utilising Blockchain

Abstract

Many Internet users employ a multitude of online services. Many services require the same data to be entered and users enter it repeatedly. Instead of entering information for every new service a user wants to use, we propose a system that allows users to simply share a set of information with any service they want to use. The information is entered once and stored in a distributed storage system. Users can easily share the data with any service provider, in order to use a service. Our proposed system makes use of the distributed ledger, provided by blockchains, to manage access rights. By taking the data away from the service providers, the personal data is also protected against unwanted data leaks.
