Vaultage

Vaultage is a collaborative work between University of Maastricht and University of York that aims to move users' personal data from centralize servers to their personal data vaults/devices. It is designed to comply with the GDPR (https://gdpr.eu/) regulation on data protection and apply FAIR (Findable, Accessible, Interoperable, Re-usable) (https://www.go-fair.org/fair-principles/) data principles.

How does Vaultage work?

Security

• Public Key Exchange. Public keys between users are exchanged via emails, messengers, etc., or further extension of the app.
• Double Encryption. Messages are encrypted (decrypted) using both users' keys: sender private key + receiver public key (receiver private key + sender public key).
• Encryption Algorithm. RSA, key length 512 bits.

Rdbd Access Control

1. At the API level?
2. At the file / data level?
   1. Access control as implemented in UNIX filesystem?
   2. Access control as implemented in database systems?

Example

FAIRNet is the FAIR version of Facebook that stores users' personal data in their personal data vaults/devices. It uses the Spark framework (http://sparkjava.com/).

How to Run the Demo

To run the early prototype of this project:

1. Download the source code from https://github.com/alfayohannis/rdbd.
2. Import the project to Eclipse. There are four projects:
   • org.rdbd.core.client (the implementation of Rdbd client)
   • org.rdbd.core.client.windows (the client for Windows OS)
   • org.rdbd.core.server (the implementation of Rdbd server)
   • org.rdbd.demo.fairnet (the implementation of the FAIRNet demo)
3. Download Apache ActiveMQ from https://activemq.apache.org/components/classic/download/.
4. Unzip and run the server by executing bin/activemq start using command prompt or console.
5. Run RDBDWindows.java inside the org.rdbd.core.client.windows project. The client will listen incoming messages.
6. Run the org.rdbd.demo.fairnet project.
7. Go to http://localhost:4567/account/create/ using your browser.
8. Fill in the username and full name textboxes. For now, the username field should be filled with 'foo'.
9. Submit the form.
10. Go to the console of RDBDWindows.java that you previously ran on Eclipse. You will see that the client receive the message sent by the server.
