Are there existing web sites that use a photo as a electronic signature?

The use case: to sign a electronic document, users view the document, and if they agree take a picture of themselves with their webcam (done through Flash from the browser). Then a PDF is generated containing the document and the picture in place of signature.

This is a biometric signature, which is not as strong as a digital (cryptographic) signature, but stronger than having users draw their signature, as a photo is harder to forge than a drawn signature.

Has anyone seen this technique being used on an existing web site?
