Capture DIgitized Signature

Tracer

Has anyone attempted to create a MySql/PHP solution to capture and archive digital signatures using topaz pads/tablets? Topaz makes the following API's available

http://www.topazsystems.com/Software/index.htm

Can this be done utilizing PHP/MySql?

I would basically want to first SCAN a barcode, lookup info via ODBC using the barcode as the key, then capture a persons signature and save the signature and imported odbc info into a MySql db.

Any Comments/Experience would be GREATLY appreciated

I didn't read the API, but assuming that the program saves the signature as an image file (gif|jpg), you should be able to do it with not too much trouble... Look up ImageMagick

I am looking for a way php can use public and private keys with digital signatures. Any thing signed with a users private key will alter the "thing" in a way that if tampered with it wil not validate using the users public key. Does anyone know anything about doing this with php and mysql with digital signatures?

Anything about where i can get or generate private keys and thier public key?

This is exactly what I have done.

I use topaz tablets. Topaz provides a java interface which you can embed into your PHP/HTML. The Topaz java bean will hash the signature with pretty much any key encryption you would like to use. I then use a timestamp field, and a text field in the MySQL database to verify modifications (If the two fields don't match the signature isn't decrypted).

Check out the topaz site...Lots of useful info and code. I belive it is www.topaz.com
