As an in-charge of a data set, considering how to share and what objective to use the sharing data should be well organized and planned. During the data sharing process, the data which contain any identifiers must be de-identified to protect data privacy and confidentiality. Informed consent for all data owners must be done regularly and properly. Cleaning data to prevent any missing values and error of data must be completed before sharing. On the data transferring process, encryption and access restriction to prevent data fraud are essential. Who can access the data and whose purpose must be screened and evaluated ethically and legally by the committee. This process may be except due to an emergency situation like an outbreak to prevent the spreading of disease. We can analyze and use shared data to make more new drugs, treatments, policies, and ideas for the research.
