Partage de documents sécurisé dans le Cloud Personnel

Abstract : These past years have witnessed a growing digitalization of our lives, combined with an explosion of personal data quantity on the Internet. This has opened the way to a data-driven market focused on their analysis for profiling purposes, increasingly intrusive and most of the time performed without the user acknowledgement. At the same time, states surveillances are being established, raising concerns about potential dystopias, until now confined in the literature. To tackle this situation, the Personal Cloud paradigm has risen: each user has now the possibility to store and manage all her digital life in a trusted space in which she is the sole responsible.However, this empowerment leads to a governance switch. The user is now in charge of the security and the administration of their data. In particular in the sharing context, where the data is exposed to people or third-parties. Therefore, this thesis proposes a new paradigm in the way the sharing is performed in the Personal Cloud. It focuses on security, control and on a better simplicity of use for the users. Three contributions are made in this direction: (i) a Privacy-by-Design architecture, dedicated for the Personal Cloud context, (ii) a sharing model suited for the Personal Cloud properties and (iii) a sharing protocol implemented in the Cozy platform.
