One method, and I stress this is only one method, is the Levenshtein distance at

http://en.wikibooks.org/wiki/Algorithm_implementation/Strings/Levenshtein_distance#Ruby

and it has code, in ruby!

"Difference" in this case does not seem very well defined.

There is strmask (http://rubyworks.github.com/strmask/)

Also the Levenshtein distance is String#edit_distance in Ruby Facets.

There's a "differ" gem which could be useful for you.
