Hash code

Hi everyone.

I need a good idea.

I'm developing database (Access2003, WinXP SP2) for documents storing.
It is expected that documents will be in PDF format. Particulary I'm meaning scietific articles, patents, technical documents etc.

Obviously I should implement a mechanism preventing files duplicating.
A part of it will be generating hash code uniquely identifying file content.

Does anybody can propose any file hashing algorithm?

I don't know if you can use the algorithm discussed in the link, but the article covers all of the issues relating to a document storage and retrieval algorithm.
