With the advent of the 4th industrial revolution, the amount of data has increased exponentially, and artificial intelligence using big data is being used in various industries. In particular, with the introduction of artificial intelligence in the medical industry, the industry has expanded from disease diagnosis to disease prevention and customized treatment. The domestic precision medical industry is a state-of-the-art industry and continues to develop. However, in the case of the precision medicine industry, it has not yet been designated as a national core technology, so there are no policy and technical measures against the leakage of personal medical data and industrial technology used for precision medicine. Therefore, in this paper, after comparing domestic and foreign policies on medical data, we try to analyze the industrial protection policy of the national core technology. After comparing and analyzing domestic and foreign national core technology management methods, it is intended to contribute to the prevention and protection of industrial technology leakage in the precision medical industry by introducing the precision medical industry to national core technology and proposing an additional management system.
