With the development of mobile technology and popularity of pervasive applications, more and more scientific collaborative research works are carried out
in the wild
on the move
. How to make an optimal tradeoff between deep collaboration and strict access control in mobile environments is a challenging work. In this paper, we propose
, an access control approach for collaborative scientific workflow in mobile environments. In our approach, ranked access permissions will be provided to users for continuous collaboration in disconnected settings, as well as the owned access permissions can be dynamically assigned according to the role’s evolution in various mobile contexts. The model and access control algorithms of
are elaborated and a prototype is implemented on Android mobile devices in collaborative proteomics research platform
to demonstrate its effectiveness.
