Use Cases
for trusted data exchange

Dexes creates the ecosystem to share data that was not shared before. Data that is privacy or commercial sensitive can be shared safely. 

Some data is not shared in time or not shared at all between private and public partners. Economic and social value is lost. On the right we show a few examples of use cases that profit from a data exchange.

Harbour security

Data about the contents of ships in the harbor could help the firefighters to handle a crisis more efficiently.

Energy distribution

Data about availability and demand for energy helps to reduce pressure on infrastructure.

Circulair building

Data about the circulair value of materials in building helps to improve circularity.

Safe Health data

Privacy sensitive data can be shared by bringing the algorithms to the data for analysis.


Concepts for a
Trusted Data Exchange

Find, match, make a deal and share data

The process of sharing data on the Dexes platform is simple, efficient and transparant. Find a dataset you want, match your attributes with the conditions that the owner set and make a datadeal. Then access the data.

Irrefutable datadeals

The Datadeal stores the validation of conditions for sharing data against the attributes of the data user. The datadeal is irrefutable and can be referenced by the data owner and data user. The owner knows who is using the data. The user has a record of the agreed terms for using the data.

Governance & communities

Sharing data can work when conditions for sharing are transparant. A community of domain owners can facilitate the data sharing process. An independent foundation governs the general rules of operation and handles exceptions.

Distributed data storage & access

The Data Exchange contains no data itself. The data-owners stay in control of the conditions and the access to their data. Dexes offers the Dexpod based on Solid technology as a store-and-access solution for local use by data-owners. This can be a corporate, a government or an individual.
