Table I.5 – Use case – Managing personal information

Title Managing personal information
Description A data analyst (at a BDC) requests the provenance information on 'data 1' to BDSP. At this time,
BDSP:
– traces history of 'data 1';
– checks whether each data includes personal information and find out 'data 3' includes
personal information;
– checks BDC's access right on 'data 3'.
If BDC has the access right on 'data 3', BDSP aggregates provenance units and responds it. If not,
BDSP responds the provenance information excluding provenance unit 3 or abstracts the
provenance information based on a predefined policy and responds it.
