You can't, but if you have matching data, the hash will match. For example:
List A:
- Item 234 sample hash: asdfsdd
- Bubble 332 sample hash: ef2342h
- Wonky 093 sample hash: 23jasld
List B:
- Item 324 sample hash: eja8357
- Silly 325 sample hash: aj3hht5
- Item 234 sample hash: asdfsdd
That would be the "match", then they can ask for the data behind the
match to be revealed.
