Bluebeam Revu, combined with the use of ACES certificates issued by IdenTrust, can:

  • Replace wet signatures with non-repudiable, digital signatures bound to an individual’s identity and company affiliation
  • Eliminate paper by utilizing auditable digital-signatures applied to electronic documents
  • Streamline processes and compress timelines by utilizing online distribution and document routing

The multi-threaded process of signing, sealing and submitting plans to a State Department of Transportation can be time consuming, paper intensive, resource draining and error prone. To minimize these headaches and achieve business efficiencies, many professional engineering firms incorporate the use of IdenTrust ACES digital certificates with Bluebeam Revu.

Digital signing of PDF documents within Bluebeam Revu is one of the most common uses for an ACES digital certificate. Each digital signature placed on a document is independently validated to approve the document in its current state. If changes are made to the document after the digital signature is placed, the status of previous signatures change accordingly.

An important distinction between a digital signature and an electronic signature is that the latter is not validated for authenticity to the signer’s identity. An electronic signature is simply an electronic representation of an anonymous autograph or an online action to indicate approval; a digital signature contains a unique digital ID, linked to the signer’s identity, which verifies its authenticity. These important distinctions are shown here:

A legal term A functional term
Tied to a specific individual via a PKI-based digital certificate Not technically bound to a specific individual or validation process
Created using a digital algorithm to bind the document using a digital certificate, resulting in a unique "fingerprint" Created through multiple options: typed names, scanned images or a “click-wrap” agreement on a website
Non-repudiable and auditable Legal, but not easily audited and can be repudiated
A "hash" of the content being signed – any tampering will be evident Cannot be verified through electronic means

Using IdenTrust as the Certification Authority makes it easy to verify your identity to other parties, bypassing the need for pre-established mutual trust. Just as a driver’s license or passport identifies you in a face-to-face transaction, an IdenTrust ACES digital certificate identifies you in an online transaction.

ACES Business Representative Certificates allow individuals to authenticate themselves as an employee of a valid business in government transactions to digitally sign PDFs and other types of documents, encrypt and sign email, and gain access to restricted government web sites.
