Paul Joins the Cozy Crew

When you build software, most of the time you want to deliver quickly. But some subjects require patience and time. Secure data sharing is one of them. We think the future of Cozy will rely a lot on social features. Because we are concerned by the security, we decided to reach researchers in that field.

When you build software, most of the time you want to deliver quickly. But some subjects require patience. Among them, there is the secure data sharing. At Cozy, we think that the future of personal cloud will rely a lot on social features. Because we are concerned about the security and because we consider that it must become a main focus in our software, we decided to reach researchers in that field. In this context, Benjamin met the SMIS laboratory (SMIS stands for Secure and Mobile Information Systems).

After he introduced Cozy to them and great discussions, they proposed us to hire Paul Tran-Van, a young and talented engineer who wanted to do a PhD about access control and secure communications. This hiring would be the opportunity to work closely with the SMIS laboratory and to fund Paul's research.

As you may guess, we accepted their proposal! Prior to join us, Paul was graduated from ENSIIE. He specialised in system conception and graduated from the COSY master (no joke!) at USVQ. Then, he joined the SMIS laboratory to work as an engineer. He worked on problematics related to indexation in constrained environment.

What will his research be about? The tagline is "Secure Document Sharing for Personal Clouds". The main idea is to propose an interoperable sharing model. The user will be able to write access rules to enable a fine control about his/her personal data. The first challenge is to make it simple and useable. The second challenge will be to make the protocol and the storage secured (big task that will require years of work).

The knowledge of the SMIS laboratory will be a key ingredient for Paul to reach his goals. They propose to rely on a secured hardware that stores your access rules. Once plugged on your computer, it makes the sharing possible by providing access key to documents. This technology is called
PlugDB. Building bridges and integration between Cozy and PlugDB will be another Paul's objective.

We expect a lot from Paul's research. With the information he's going to grab, we'll be able to build the ultimate personal cloud experience! Yes Paul, you have some pressure on your shoulders ;) !
