How to Mask Sensitive Data in Attachment Files (e.g., Driver License, Passport) in Incident Table?

[DhinakarS]

Hi everyone,

I'm working on a use case in my ServiceNow Personal Developer Instance (PDI) where I need to automatically mask sensitive information (like driver license and passport numbers) when a file is attached to the Incident table.

Goal:

• Detect patterns like:

  • Driver license number: VIC1234567

  • Passport number: N1234567

• Automatically mask them as:

  • VIC*******

  • N*******

• This should happen immediately after the file is attached.

This is my requirement can I get any suggestions how can be it done.
Thanks in advance.

Hello @DhinakarS ,

That's not possible.

ServiceNow has data redaction features, but only for inbound emails and data added to a record itself.

Not for attachments. Also consider that someone could just attach a screen shot that shows these sensitive numbers.

Regards,

Robert

@DhinakarS 

you can't read attachment content and mask particular info within it.

why not use Column level encryption and show attachments only to the users passing encryption context?

Hi @DhinakarS 

you forgot to mention which types of files you are referring to: Plain Text? Images? Write protected PDFs?

Do you really expect for all these different types a generic solution?
