公民逝世后器官捐献与移植工作中存在多部门、多节点间的数据传输与交换，各节点信息交换过程中，存在信息泄漏的风险。随着互联网终端在公民逝世后器官捐献与移植过程中成为数据报送的主要载体，互联网数据泄露亦成为不能不正面应对的问题。本文旨在探讨通过区块链技术对公民逝世后器官捐献与移植过程中数据传输进行加密，并通过不同密钥赋予不同人群数据获取权限，实现数据的加密传输、保存及应用。

There is a risk of information leakage in the work of organ donation and transplantation after the death of citizens in multi-departmental and multi-node data transmission, and in the process of information exchange between nodes. As the internet terminals become the main carrier of data reporting in the process of organ donation and transplantation after the death of citizens, the Internet data leakage has also become a problem that cannot be dealt with head-on. The purpose of this paper is to explore the encryption of data transmission during organ donation and transplantation after the death of citizens through blockchain technology, and the right to obtain data from different groups of people through different keys, so as to realize the encrypted transmission, preservation and application of data.
