Assure data integrity and protect against tampering by providing irrefutable evidence of authenticity in one step.
Secure and timestamp your important digital files by linking a unique digital identifier, a hash code that you create, with a second unique United States Postal Service® Electronic Postmark® (USPS® EPM®) seal as verification within your own software applications or web services. The USPS EPM transaction I.D. code provides a digital fingerprint of files including the exact moment that the USPS EPM is linked to the hash code and then stored in the Authentidate USPS EPM web service data center. The USPS® provides back-up and verification of USPS EPM seals issued by Authentidate®. The Authentidate USPS EPM web service along with the USPS as a backup verifier provides truly long-term trusted third-party evidence of content authenticity with a certified timestamp when the USPS EPM was applied.
Verification that a USPS EPM is matched to the correct hash code assures that the digital integrity of electronic files, electronic signatures or other important data is identical since the USPS EPM was applied. The Authentidate Software Development Kit (SDK) simplifies the process of assuring data integrity and protecting against tampering by making the USPS EPM and Authentidate's USPS EPM web service available to corporate software developers or system integrators (OEM application developers). Authentidate is an authorized USPS EPM Service provider.
