well, electronic signature using PKI are meant to be generated using the private key which has to be kept secret in the safest place you can ever find. you have to understand that crypto keys are just sequences of 1's and 0's and there is nothing to link biologically to you. another way to provide more security on an encrypted document is by signing your keys with a third certificate authority whose keys are globally available for clients to check the authenticity/integrity of your signed docs. g.

I know that Photoshop can add watermarks to documents if that helps at all? xyberpix On Tue, 2004-10-26 at 16:10, Spencer, Mark wrote:On business documents (those that still live in the paper world) where public/private keys and signature verification are unavailable, is there a way to make an electronic signature (a handwritten one that has been scanned in) more secure? Possibly by watermarking? Anyone can scan in a handwritten signature and paste it into a document, but I'm curious about how one might watermark or otherwise secure it. Thanks! Mark
