New USPS EPM Digitally Protects Microsoft Documents
The extension requires the user to digitally sign a document when applying a USPS Electronic Postmark within Microsoft Office XP and Microsoft Office 2003. The system will allow: digital signing of a Microsoft Office Word document using digital certificates; electronic content sealing and time/date stamping with the USPS EPM; and subsequent verification of an MS Word document's validity, authenticity and integrity.
The extension can be downloaded at www.uspsepm.com/epm/epm_office_ext/. It was co-developed by AuthentiDate Inc. and Microsoft.
