Let me also add, without knowing what the information is, that if it involves fraud of investment accounts, etc, there are probably tons of computer printouts of corporate records that may have SSNs, account #s, access codes, etc...No one has time to redact (black out or white out) millions of irrelevant items. So it could be a volumn problem and the receiver of the info must be put on notice not to use sensitive data of no relevance to the case, but part of the discovery.
