Auto-Classification in Collate

Collate identifies PII data and auto tags or suggests the tags. The data profiler automatically tags the PII-Sensitive data. The addition of tags about PII data helps consumers and governance teams identify data that needs to be treated carefully. In the example below, the columns ‘user_name’ and ‘social security number’ are auto-tagged as PII-sensitive. This works using NLP as part of the profiler during ingestion.

User_name and Social Security Number are Auto-Classified as PII Sensitive

In the below example, the column ‘dwh_x10’ is also auto-tagged as PII Sensitive, even though the column name does not provide much information.

When we look at the content of the column ‘dwh_x10’ in the Sample Data tab, it becomes clear that the auto-classification is based on the data in the column.
