New USPS EPM Digitally Protects Microsoft Documents
The U.S. Postal Service announced last week the availability of the USPS Electronic Postmark Extension for Microsoft Office, giving users tamper detection and date/time stamping of electronic documents and files.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.
