As data begins to be spotlighted as a field of industry, many countries are in a hurry to legislate on data. Europe is probably the most active region. The EU, which has refined the data system in Europe through the EU Governance Strategy and GDPR enactment, has recently announced the Proposal of EU Data Act to spur the data industry. The biggest feature of this legislative bill is that it distinguishes data industry entities and proposes data transactions through bond transactions between them. This method is meaningful in that it reduces exhausting rights disputes arising from existing data ownership issues and activates data exchange. On the other hand, Korea enacted the Data Industry Act at the same time and is striving to foster the data industry and protect data. However, the current data industry law is limited to presenting various support systems, so there is also a limit to presenting legal relationships between data stakeholders of the industry.
