The problem is, this is not a hash that is simply matched against
another hash 1:1.

When comparing two hashes, a small percentage of difference is allowed
on the values for better results. Sometimes it is a 100% match, but it
might also be a 99% match. So matching two hashes is rather complex.
If you know perl, feel free to check out the routines :)
