Some sensitive data are not needed for future processing steps, or are not allowed to appear in target files or reports in any form.
When that happens, you need to prevent private fields within your data sources from appearing in your output results.
Most tools available for processing files or reports are either cumbersome or expensive, and do offer the ability to combine field-level redaction from flat files, much less combine that ability with other field-level protections like encryption, de-identification, or pseudonymous data masks..
Solutions:
If you are processing files, you can select which input fields will go
to output reports and hand-off files on a need-to-know basis.
With the
CoSort product's SortCL tool, you can selectively omit records from your input or output files based on conditional evaluation logic. That is filtering. Or, you can simply not specify certain input fields in the output target. That is redaction.
By using SortCL to manipulate, report from, and secure your flat-file data, you can now simultaneously specify all your output field choices and formats -- plus any additional protection and transformation functions you need on the fields you output -- according to your business needs and privacy rules.
