Improving Reliability of Data Distribution Across Categories of Business and Industries with Chain Data Lineage

Today, companies are overflowing with a variety of data, inside and out. Recently, there is a growing movement to push the co-creation of innovative digital businesses by distributing and utilizing valuable data that cannot be obtained independently between different companies. The realization of a world like this, however, requires the data shared between companies to be reliable. Specifically, it must be possible to verify where the data have come from and how they have been processed and, when personal data are included, whether or not individuals have given consent for the data to be provided. Fujitsu Laboratories is moving ahead with research and development relating to data distribution and utilization technology that resolves these issues and enables the safe use of data. This paper first presents the issues relating to data reliability in data distribution. Then, it describes the Fujitsu-developed Chain Data Lineage technology, which improves the reliability of data exchanged across different categories of business and industries, together with examples of its application.
