We propose a dynamical access control database management system for disaster information sharing. In disaster events, many kind of information can be effective to decrease disaster damage, but some information such as personal safety information cannot be fully public. It is needed to fine grained flexible access control.The system we propose can change data access permission by stored contents dynamically.
