SIX REASONS TO USE CADsecurity™ Signature and Watermark

Frustrated with standard DWG Security ? Did somebody steal parts of your DWG drawing again ?
Forget passwords that do not protect a simple "copy and paste" of your design.
It’s time to move onto to something better.


Here are six reasons to start CADsecurity Signature for AutoCAD today.


CADsecurity™ Signature
is well hidden in your drawing



CADsecurity™ Signature
uses simple AutoCAD Entities


CADsecurity™ Signature
can be easily tracked only if you know the key.



CADsecurity™ Signature
can be hidden by placing it in Blocks



CADsecurity™ Signature
can continue to protect your drawing even after
a "copy and paste" of a drawing's parts.



CADsecurity™ Signature
can continue to protect your drawing even
after DWG -> PDF -> DWG conversion.


You can’t separate CADsecurity Signature from the drawing elements, the Signature is part
of the drawing elements.

CADsecurity Signature is positioned randomly and well hidden in your drawing.

Nobody can identify the existence of CADsecurity Signature unless they know your
unique character string.

CADsecurity Signature is attached to a normal drawing’s parts like blocks, entities,
simple lines and polylines.

If you copy a small part of the drawing it is very likely that you will copy CADsecurity™ Signature too.

You can prove the existence of the CADsecurity Signature even after DWG to PDF and

Most of us can say that at one time or another we have dealt with security issues like spyware, viruses, and scams. 
Today, security is an important issue for big companies and private users.


Protection of intellectual property is crucial for CAD users to prevent plagiarism and to stop the leaking of confidential information.

We offer a solution to keep your CAD files secure.

Why Do You Need to Secure Your Files?

Everyone wants to secure their CAD files. Anyone can modify your files if they can gain unauthorized excess and publish them as their own. This can jeopardize your business.


Is Password Protection of Files Effective?

Most CAD programs allow users to secure their CAD files with a password, meaning that unauthorized users won’t be able to access them.  AutoCAD,  includes this option to help keep your DWG files secure. Keeping your files password-protected means that you have control over who views and works with your files.


However, you have no control over someone copying and pasting into a password free file during usual CAD work!


The classical data theft happens rarely. Most data thefts are done by former employees who try to start a similar business. Data theft is also committed by people who are working for other companies and who are simply selling parts of your drawings as a block-library on the Internet.

Use Prevention to Protect Your Files!

The best protection for your drawings is prevention using digital traps generated randomly in your drawings made by our software CADsecurity™ Signature.
