I found the patent filing to be an amusing read, at least with respect to the z/OS specific stuff. There is no SS type of dump record. And if you wanted to process a dump, you certainly wouldn't do it by reading the raw dump records (as that wouldn't work very well for data which crosses a 4k boundary (and thus crosses a dump record boundary). You would do it by writing an IPCS VERBEXIT program, or a Rexx exec, which uses IPCS services to access the dump, and prepare the lists of storage ranges for modification and/or modification avoidance. The ranges would then be input to an IPCS function which would use the IPCS storage map to translate the address ranges into ranges within dump records. And then that would be the input into a program which does the copying with modifications.
We did have a meeting in z/OS development quite a few years ago to discuss someone's wish for this type of function for z/OS dumps. We concluded that in general, identifying the sensitive data to be modified would be so problematic that it was not worth pursuing. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp.
