Tip of the Day: Using a Segmented Mapping Algorithm with Agile Masking

Segmented mapping algorithms let you create unique masked values by dividing a target value into separate segments and masking each segment individually. Optionally, you can preserve the semantically rich part of a value while providing a unique value for the remainder. This is especially useful for primary keys or columns that need to be unique because they are part of a unique index.

  • When using segmented mapping algorithms for primary and foreign keys, to make sure they match, you must use the same segmented mapping algorithm for each.

Does the segment mapping algorithm use the same replacement values across all databases and all systems?
