making jpeg image of signature secure

Posted on 2008-10-01

My employer wants to create a jpeg image of my signature and have me afix it to electronic documents. I am a bit concerned about signing documents in this fashion. Anyone could take the image and attach it to any other document, etc. Is there anyway to make this image uncopyable after I afix it? If not, what is the best way to make a signature secure?

What kind of documents are you trying to "sign"? If it's something that can be converted and distributed as PDF, you can use a "real" digital signature (which can actually include an image of your scanned signature) to encrypt and sign your documents. Such a signature would also allow you to verify that nobody modified the document since you signed it. Let me know if you want more information about PDFs and digital signatures.

The majority of the documents are PDF. There are some that are Excel and Word documents.

Can you convert the Excel and Word documents to PDF before you distribute them?

Yes, I believe I would be able to convert them to PDF, then I could use the digital signature in the PDF software.
