Abstract: Techniques are described herein for determining whether data sets of real information in databases indicate PII information. The data sets are stored in a first table and parsed for keywords related to the names of data items in the sets. The keywords are stored in the second table in a many-to-many relationship with related data items in the first table. The number of times the keywords are parsed from the data items is counted, as well as the number of times each keyword is associated with a PII-designated data item. The counted numbers are then used in analyzing new data sets to identify the likelihood that the new data sets contain any PII data items.
