Thanks for your comment :) So eventually, if you can generate all possible set of fingerprints which match that hash and "cross check" it with another fingerprint systems, you could be able to approach the guy fingerprint? (I mean you maybe reduce the set to a reasonable size) The use case is quite overkill though! Also, generating all possible set of fingerprints is probably a lot of computation.

The other fingerprint system would need to be compatible with your data source, but if you had a compatible system and if you could generate every potential fingerprint for a given hash you could definitely use cross-checking to find any individual in your several million who also happens to be in the database. I think the biggest potential problem with that approach is both incompatibility and also false-positives. You might have "too many" matches for it to be useful for much.
