The Personal Cloud paradigm is emerging through a myriad of solutions offered to users to let them gather and manage their whole digital life. This paradigm shift towards user empowerment raises fundamental questions with regards to the appropriateness of the data management functionalities and protection techniques which are offered by existing solutions to laymen users. This year, we reviewed, compared and analyzed personal cloud alternatives in terms of the functionalities they provide and the threat models they target. From this analysis, we derived a general set of security requirements that any Personal Data Management System (PDMS) should consider. We then identified the challenges of implementing such a PDMS and proposed a preliminary design for an extensive and secure PDMS reference architecture satisfying the considered requirements. Finally, we discussed several important research challenges remaining to be addressed to achieve a mature PDMS ecosystem. A first paper making the functionality and security standpoint in PDMS solutions, proposing five security goals and a preliminary architecture to fulfill these goal based on Trusted Execution Environments was published at IS'19 [12], and preliminary results on the case of a crowdsensing architecture was presented at Middleware'18 [15] and BDA'18 [18].
