Notice:
Digital Signature is not just a scanning bitmap of a handwriting signature, is not also just a bitmap vectorized.
It's based on public key infrastructure.

The purpose of signature

Apply Visualized Digital Signature for AutoCAD drawings, with anti-clone and non-repudiation properties. If the drawing is modified the signature disappears immediately. Just like a traditional handwritten signature, it can be displayed and plotted.

If you're holding a hard copy of a drawing that's been signed off by the Chief Architect or Engineer, you can be fairly certain the drawing hasn't been modified since it was released. But if someone sends you an electronic version of the drawing file, how do you know if it's valid? Maybe it's been changed since it was last approved. Has it actually been approved? There's no easy way to lock down that drawing so no more changes can be made. Enter Digital Signatures!

It's powerful, and it's very easy! Only 3 steps.
Step1: Drawing handwriting by mouse. Setp 2: Add the signature in AutoCAD. Step 3: Experience power.


1. Drawing handwriting by mouse to make your signature profile


2. Add it in AutoCAD and attach a digital signature ID automaticlly.

First, look at the signature by a traditional pen on paper, and your purpose is nothing more than “Trust” and “Responsibility ”. As your signature is accepted, the content of the document paper has been accepted too, and you have the responsibility for the content.

  • A service that provides a proof of the integrity and origin of data.
  • An authentication that can be asserted to be genuine with high assurance.

Digital Signature is the same as the properties of tamper-proofing, anti-clone and non-repudiation of disputed charges.

  • Tamper-proofing: using digital signature can help you to identify the documents are original, and not unauthorized modified.
  • Anti-clone: you digital signature is not like a bitmap, and it cannot be copied. The digital signature is a string encrypted using Pubic Key Infrastructure, and it’s composed by your certificate, and document contents. Access to the public key does not enable a fraudulent party to fake a valid signature.
  • Non-repudiation: an entity that has signed some information cannot later deny having signed it.

Advantages of SmartSignSafety

  • With the properties of tamper-proofing, anti-clone and non-repudiation.
  • Smart. In case of modification of the drawing, the signature disappears immediately.
  • Visualization. Like the traditional handwriting signature, it can be displayed and plotted.
In case of modification of the drawing, the signature disappears immediately
