Electronic Signatures and Infrastructures (ESI); PDF Advanced Electronic Signature Profiles (PAdES); Printable Representations of Electronic Signatures

active, Most Current
Organization: ETSI
Publication Date: 1 February 2011
Status: active
Page Count: 10
scope:

The present document discusses the techniques that may be used for printable representations of advanced electronic signatures (AdES) in PDFs. Specifically, focusing on the printable representation of the AdES signature value, for example as a alphanumeric string or bar code. A separate document (TS 102 778-6 [i.4]) covers the issues of visually displaying other information contained in the signature.

The printable representation of the advanced electronic signature value is aimed at electronic signatures created on electronic documents which are then printed. It can be used to verify that a printed signature value stored on an authoritative printed document equals to that one derived from the electronic version of the document. It does not necessarily enable the authenticity of the printed document to be verified using electronic techniques without reference back to the electronic document from which the printed document was derived. As such, electronic/digital documents need to be validated using the included electronic signature and the standard methods for verification & validation of that signature. The printed representation should mainly be used to provide a way to match the printed version to the electronic version from which it originates - a form of "secured fingerprint".

The present document discusses the techniques that may be used in applying printable signatures to PDF documents. It is not aimed at providing a normative set of requirement but rather collects together information that may at a later date by used to form the basis of a formal ETSI specification.
