Upload, duplicated files, MD5 Sum Check, Federated Search

Guest

Hello everybody
I’m facing the current challenge! I have an intranet built in federated
search that allows me to search in different subscribed databases and at the
same time I have a folder that works like the depository of all the documents
that may have interest to my company. So, the procedure is: if someone finds
a document with interest for the company it should catalog it and save it to
this folder so that it can be searched by anyone on the intranet. When saving
the file, the application should be able to warn the user if the file has
already been saved. For this I am using an MD5 Sum Check but I don’t know if
this is the best one. So suggestions are welcome!

So my problem is: when someone is searching the web using the federated
search interface the system should be able to check if the file has already
been saved even though if the file is in a different database or has a
different name. So what I would like to know is if there is a way of
generating an MD5 Sum of a file without downloading it? Or, if any of you has
ever faced the same problem, how did you solve it?

Best regards and a big thank you in advance

And
