WG: AW: Fw: [dss-x] Visual Signatures profile


Hi Leonard ! Konrad said something very important yesterday : 'Think of requirements, not of existing solutions !' I hope I remember it correctly ... but it's true anyway. 2D barcodes are funny stuff to impress my kids and colleagues, but our real use case is : Mass signing of PDF invoice documents. That's not a tricky requirement at all, but I just can't do it using DSS right now ! So I would like to go for a signing profile for PDF documents starting with the core's successful keep-it-simple approach in mind : - One signature at a time - Pre-configured signature field included in the document - DSS's signature placement enhanced to be a pointer into a PDF doc - No update of the PDF beyond the signature field Same for Verification. I have no experience with timestamps in PDFs, maybe the simple signature approach will fit ?? This would introduce a new profile with focus on PDF as a signature container format, independent from the visual signature efforts. Does this makes sense to you ? More sophisticated profiles may aggregate this functionality, but that's not my use case. Opinions welcome Andreas
