Secure, cloud-based storage and processing of sensitive documents

The SeClosed project aims to deliver a set of practical data protection techniques and data access middleware for secure document storage and processing. These solutions can be deployed in cloud environments and other untrusted storage solutions.

Cloud-based storage solutions

Cloud computing and Software-as-a-Service (SaaS) are becoming increasingly important in many business segments. Software companies are evolving into SaaS companies, and organizations that rely on the cloud to reduce operational costs become their clients. However, because of the high-risk nature of their data, and because current protection techniques are not capable of protecting it in encrypted form, many of these corporate clients find cloud-based storage solutions untrustworthy.

Data protection techniques and middleware

SeClosed is set to deliver data protection techniques and middleware for secure document storage that can be deployed in cloud storage situations. These solutions will be based on state-of-the-art cryptographic and secure data mining techniques. In addition, middleware developed by SeClosed will offer flexible composition and configuration of different data protection techniques that can be applied to different layers of software architecture.

Building trust, cutting costs

The results of the SeClosed project will optimize the SaaS offerings of Flemish industry partners, boosting customer trust, cutting costs and increasing their market shares. The advanced data security solutions developed by SeClosed will also give cloud infrastructure providers a cutting-edge advantage over their low-cost public competitors.

Financial and medical document management

As this field is novel, SeClosed will require a significant amount of research, study and innovation in terms of theoretical data protection. However, the consortium will focus heavily on making sure that their innovations are functional in real environments. As such, outcomes of the project must be proven based on industry application cases in the fields of financial and medical document management.


"A layered trust model, where trust relations are challenged at various levels, requires advanced data protection and encryption techniques to store and process application data. To meet these needs, SeClosed will deliver applicable techniques that can be used on top of untrusted storage solutions."
