One of the main goals of the TRAPEZE project is to provide system prototype demonstration. In other words, we are seeking to monitor, evaluate, document and assess the viability and performance of the TRAPEZE integrated solution in real-world scenarios.

For this reason, we plan to deploy three different use case pilots that will evaluate TRAPEZE’s proposed scalable policy-aware Linked Data architecture under real-world conditions. The conditions imposed will apply to functionality requirements, and just as importantly, to non-functional requirements such as performance, scalability and security. All 3 use case pilots include the processing and aggregation of large amounts of personal data from various data sources, with policies specified at different levels of granularity.

By testing and evaluating the Linked Data architecture through these different scenarios, it must be understood that TRAPEZE’s overall methodology will have to be flexible, robust, scalable and ethically compliant, in order to handle the complexity and heterogeneity of the required data security and privacy solutions, and in order to accommodate the different stakeholders involved in the data value chain.

The three pilots defined and developed in TRAPEZE are coordinated by different use case partners: Informatie Vlaanderen (Belguim), Deutsche Telekom (Germany), CaixaBank (Spain). The use cases are further described as follows:

• Pilot 1 – Informatie Vlaanderen (AIV): “My Citizen Profile”: AIV wants to leverage Linked Data and decentralized principles using a web-based ecosystem that separates data from their applications making use of “Solid” (Streamlining governmental data processes by putting citizens in control of their own data) in the existing user-centric back office and interface of “My Citizen Profile” (an application which provides an overview of all authentic government information). Like TRAPEZE, Solid aims to give users true control over their data. The AIV pilot is an opportunity to demonstrate this mindset and show its complementarity with other approaches to personal data governance and protection.

• Pilot 2 – Deutsche Telekom (DT): Tools & Applications for “Data Intelligence Hub”: DT’s main concern is to make a language for privacy policies and tools available for the Data Intelligence Hub (DIH) but also as integral parts of the DIH data management platform. This enables the DIH to safely deal with personal data in the context of GDPR and other regulations. First applications will be trialed with DT’s approach for consent management, the “group consent clause” which allows customers (i.e. citizens) to grant, revoke and manage their consents for data using and sharing.

• Pilot 3 – CaixaBank (CXB): “Customer ID wallet”: CXB wants to develop a “Customer ID Wallet” with all the features required by GDPR and the company business as well as informed citizens. There is not yet a common platform that gives security privacy control and transparency to clients/citizens and establishes trust among sector stakeholders, knowledge sharing, and its impact remain limited. In terms of possible technical solutions to the challenge, CXB sees tremendous potential in the TRAPEZE platform and its building blocks for establishing it.

The key take-away understanding is that each use case pilot is designed to prove the feasibility of the TRAPEZE scalable policy-aware Linked Data architecture in a realistic business context.
