Automated and user involved data synchronization in collaborative e-health environments

•A collaborative data synchronization approach is presented for e-health systems.•Data synchronization is performed through automatic and users involved process.•Proposed approach uses 3 levels of users’ involvement, e.g. Auto, SemiAuto, and User.•We conduct experiment for eliciting users’ acceptance regarding the proposed system.

This paper presents a data synchronization model using automated and user involved process during execution of conflicting updates. Data synchronization is performed using three techniques, namely, (i) auto synchronization, (ii) semi-automatic synchronization, and (iii) user-involved synchronization. We have evaluated and measured users’ acceptability of the proposed data synchronization approach in an e-health environment. The results show the effectiveness of the proposed approach.
