Extensive and Secure Personal Data Management Systems.

Personal Data Management Systems (PDMS) are emerging to provide individuals with appropriate tools to collect, manage and allow applications to access their personal data. At the same time, the deployment of Trusted Execution Environments (TEE) both on the cloud (Intel SGX processors) and on smartphones (ARM TrustZone) opens new architectural perspectives for these PDMS. The PETRUS project [L1] proposes new solutions for PDMS, allowing third-party applications to exploit the individual's personal data while guaranteeing individuals the legitimacy of uses and privacy. A first proof-of-concept implementation of this new architecture has just been developed on Intel SGX processor.
