In a data distribution society, data is passed from the initial data creator to the data user, where it is processed and passed again to another data user. CADDE’s Data Lineage Management service manages the history of data distributed across multiple organizations, from the “original” data to the “processed” and “exchanged” data along the way. By mutually registering and sharing the history of “originals,” “processing,” and “exchanges” through Data Lineage Management, data users can confirm the history of the data they use, allowing both data providers and users to exchange data assuredly. The data exchange is safe and secure for both data providers and users.
