5. Key Benefits Entrust electronic data to Posts to: –Reduce information security risks –Accelerate customer adoption of lower cost online transactions –Eliminate costly “last mile” paper trails in mission-critical internal processes

6. Identity Management To protect an individual’s identity and privacy by providing a trusted electronic credential through the provision of affordable, strongly authenticated, high volume, in person proofed X.509 based digital certificates To federate (bind together) trust between all UPU countries to service general use of certificates (eg. Ensure a document can be trusted when signed by 3 different persons in 3 different countries) To enable applications to interface with and use Identity Management services in a consistent way – for example: standard XML schema and interfaces

7. Electronic PostMark (EPM)  Fundamentally a non-repudiation service supporting  Digital signature verification  Timestamping of successfully verified signatures  Standalone timestamping  Validation of certificate trust chains  Storage and archival of all non-repudiation evidence data required to support subsequent challenges  Legislative protection (ie. as for physical mail) –Internationally recognized neutral Postal 3 rd party evidence recording, storage and maintenance for non-repudiation (eg.

11. A formal UPU international standard for the EPM Interface has now been published (Status 0) and currently being tested for use with (MS Word, Sun StarOffice, Canada’s eGovernment applications) A standard XML interface is required to call the EPM service from an application –MS Word –Adobe Acrobat –Sun StarOffice –web forms –UNeDocs –etc. Web Service Definition Language (WSDL) Standard XML Interface

12. Customer Applications UNeDocs International Trade is valued at $5500 billion USD Paper based trade documentation usually is estimated to cost between 5% to 10% of the value of the traded goods
