Redaction in CMOD - What can you do?
« on: November 25, 2020, 11:29:06 AM »
So we haven't done any redaction of the statements that we've loaded to CMOD over the years, but now we have a request to do so.

This request raises 3 questions.

1. Can CMOD redact fields on the documents you load into CMOD?
- For example, let's say I had an account number on a statement and I only wanted to show the last 4 characters in viewer - is there a way to do that?

2. Can I export these same statements out of CMOD using my example above showing ONLY the last 4 of an account number on export/print?

3.  Assuming CMOD can redact BUT that I did NOT redact statements on import, is it possible to redact the statements using the same example on export - again showing only the last 4 of the account number and hiding the leading digits?

My platform specifics are CMOD 9.5 on AIX 7.2, PDF Indexer, TSM 7.1.4, and DB2 10.5.

Thanks.

There's no real built-in support for redaction in CMOD.  You can build it, I think with the preview exit, and some heavy lifting on development.  You'd want to redact-on-retrieval, so that the contents of the OnDemand archive remain accurate for legal / regulatory reasons.  You don't mention data types, or if you only want to do this for metadata.

If you wanted to do it for metadata, you could play some database-side trickery - add an extra column for the redacted data, and then use a postprocessor script at load time to populate that field, replacing characters with dashes or asterisks something similar.  Then you could do some folder tricks that woud allow you to search for a full field contents, but on retrieve, only see the redacted data.

There's some development involved, but it should be possible to build something that meets your needs.

Thanks so much for the GREAT explanation as always Justin!

The ask is to redact on export of the PDF statements themselves and not metadata.

If we end up going down this path, I'll share what/how we did it with the community!
