The goal of the PlugDB project is to design and experiment new technologies dedicated to a secured and ubiquitous management of personal data. It relies on the association of sophisticated data management techniques with cryptographic protocols embedded in a tamper-resistant device. A specific DBMS engine (PlugDB) has been designed to match the peculiarities of NAND Flash storage and the limited processing capacities of the device’s microcontroller. This project has been rewarded by ANR and OSEO in January 2010.
