ISO/CD TS 32008

A draft is being reviewed by the committee.

Abstract

This PDF Extension shows how to extend the ISO 32000-2 specification by adding support for the following: • interoperable document based electronic signature workflows • capturing parameters of a signing process defined by the initiator that includes one or multiple signers • the mechanism for allowing signers to fill predefined fields • the use of a digital signature in conjunction with an electronic signature allows verification of the document’s integrity • provisions for data needed to produce an audit trail • the process of self-signing by one or multiple signers • combination of traditional digital signature approach with popular electronic signatures This extension describes provisions in PDF files that allow the initiator to prepare a document for signing by • defining a list of signers • identifying signers with predefined authentication methods • authentication method(s) that may or may not be required • defining additional fields that the signer fills • prescribing the mechanism for building an audit trail Each signature process as described by this document shall end with applying a digital signature in order to ensure the document’s integrity
