    About the AuthentiProof® Service

    It’s easy to use the AuthentiProof Service provided by Authentidate. Simply download the Plug-In for Microsoft® Office and purchase a block of AuthentiProof timestamps to get started.

    Overview

    AuthentiProof is a web-based service to timestamp and electronically sign files and content. Once an AuthentiProof seal is applied to a file, it may be utilized as proof that a document existed in that form at that specific point in time. The AuthentiProof seal is stored by Authentidate for up to seven years from date of application.

    Authentidate defines and maintains the technical and operational standards for the AuthentiProof service, and provides verification of AuthentiProof seals issued by Authentidate.

    Secure Technology

    The Service utilizes standard cryptographic techniques and auditable time stamps to provide verification that the file has not changed since that specific point in time.

    The Service accepts and stores information describing electronic files for later non-repudiation. Electronic files, which remain at the customer location, are run through a cryptographic hash algorithm and then time-stamped using a secure auditable time stamping master clock. The hash value, timestamp, certificate, and the AuthentiProof seal, are stored by Authentidate in a highly secure repository for up to seven years from the date of application.

    Later should an electronic file be the subject of a dispute involving questions as to whether changes have been made to the content, the file’s AuthentiProof seal can be verified, indicating whether or not the file has been modified since the AuthentiProof seal was applied.

    Legal Strength

    In addition to United States federal and state legislative frameworks (Electronic Signature in Global and National Commerce Act [ESIGN, 2000], Government Paperwork Elimination Act [GPEA, 1998], Uniform Electronic Transaction Act [UETA, 1999]) which have been in existence for several years now to encourage people to form and sign contracts and agreements electronically.

    Truly Long-Term, Trusted Authenticity of Microsoft Office Files
    AuthentiProof seals issued by Authentidate, and applied to any document through the Plug-In, are stored in an approved and highly secure environment for up to seven years from the date of application. The AuthentiProof seal does not need to be renewed each year like most digital signature products. This electronic timestamp enables detection of document tampering and verification of a document’s authenticity online. Authentidate is the verifier for all AuthentiProof seals applied.

    Imagine the time, cost and energy saved! Instead of printing your Word or Excel documents that need to be signed and sent, simply keep your documents in their native form, electronically sign them with an AuthentiProof seal and save them, or send them through any email system.

    To get started creating documents that are time stamped and sealed with the Plug-In for Microsoft Office, you must create an AuthentiProof account, download the Plug-In software and click the menu item in the Word or Excel toolbar to apply an AuthentiProof seal to a document.
