What is the best software/company to use when creating a watermark on pfd/Dwg, so that it can't be removed?

We have various drawings that we need to send to clients, but the intellectual property on the drawings is highly sensitive and we don't want it being replicated. What is the best way to create a watermark that can't be removed? What is the best software/company to use? (don't trust free versions).

I assume from your Topics that you submitting your documents in PDF format.
Adobe Acrobat is good at watermarking documents as described here ...
https://helpx.adobe.com/acrobat/using/add-watermarks-pdfs.html

Then you must protect your PDF documents from being edited (which would allow removal of the watermark)
http://tv.adobe.com/watch/acrobat-x/how-to-protect-pdf-documents/

So, I suggest that you use the Professional version of Adobe Acrobat.
Be aware of the difference between Stamps and Watermarks when working with PDFs.

Dear Eirman,

Thank you very much for your help. Yes, we are looking at sending soft versions on pdf and also DWG (autoCAD). Is there a software we can use to watermark DWG documents?

Assume Adobe Acrobat X Pro, is the professional version we need. However, I have been warned that people can easily buy $10 software that removes passwords from pdf documents and thus they can easily remove the watermark etc - would you recommend using a DRM software? Or is adobe completely secure?

Thank you,

John

Free Tool: Site Down Detector

Helpful to verify reports of your own downtime, or to double check a downed website you are trying to access.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

>>easily buy $10 software that removes passwords

Unfortunately that is the truth with many software packages. And it is also in this case. If you want to be fully secure you will need to host the PDFs in your own DRM environment or create DRM wrappers to secure the document that way. If you want to be sure there is no way a PDF "in the field" can be altered, then Adobe Pro security will be too light weight.

As you can imagine Adobe Enterprise DRM is not a cheap solution and you may want to weigh up the value of the data against any associated costs. Adobe have made it quite difficult to locate pricing for this on the web and they may want to consult with you first. Worth contacting them though.

But there are also lower cost DRM solutions out there, have a look at LockLizard, this may just be good for what you need.

Dear Capt.,

Thank you for your help - have had a look at Locklizard and they look good. Is there a DRM what would work for DWG (autoCAD) files?

How do you create DRM Wrappers? Is there an easy-to-use software available?

Also what do you think of CapLinked (http://www.caplinked.com/) or File Open (http://www.fileopen.com/) are they as reliable as Locklizard?

Thank you,

John

Hi John

I have neither experience with DWG files nor with the two other programmes you mentioned, so I could not comment.

LockLizard was (is being) used by a company we worked with and they used to send legal papers to their satellite offices and were very happy with the solution.

LockLizard should create the "wrappers" for you, it is just a phrase I use to describe that there is a layer of security wrapped around via a DRM programme such as LockLizard.

Thank you for the advice.

What do you make of a program called Foxit (http://www.foxitsoftware.com/Secure_PDF_Security/protect-sign.php )?

Do you know of a similar program that works on a MAC?

Thank you,

John

Hi John

I personally have no experience with Foxit, but someone else here may. Fundamentally this is about how secure a protected PDF is when you secure it with Foxit.

But as you noticed this is not a Mac tool. However if someone here has worked with Foxit and the PDF security settings are as easy to circumvent as with Acrobat then it may not be worth looking further down this avenue.

Can you work with Password to open PDFs or do they need to be accessible for all but locked from edits? I think password protected PDFs that cannot be opened without it are much harder to manipulate thus providing a stronger protection.

Dear Capt.,

Thank you for that - sounds like Foxit, might be as unreliable as Acrobat in terms of security...if it's easy to circumvent the security settings.

Please could you explain your last paragraph more about the 'locked from edits' and how the password protected pdfs cant be opened - presume this will still be the case if they use the password removing software or not?

Thank you,

Jack

Naturally I have not tried all the various tools that promote themselves to be 'unlockers' or password removal tools. But I assume that people will always opt for free solutions rather than pay. This is judging by the ill-given advice on here (which is duly removed) of which sites offer unlock services.

The one most cited does not cope with PDFs that are protected from opening. I have tried this with favorites such as '1234' and 'password'. So there seems to be a requirement that a file can be opened before security is removed.

As said I have no great knowledge on commercial solutions but I would assume that the same restrictions must apply there too. Hence my thought that a PDF which is locked for editing AND password protected for opening has a greater chance of not being hacked than one that is just locked.

Can you easily set up a pdf so it is locked for editing and password - how do you go about this?

Thank you,

Is there any reason not to use JPGs with watermarks ?
Watermarks are totally integrated into JPGs, as they are flat files (No Layers/Elements).
You could put one in each corner and a faint diagonal one.

The only way to remove a watermark from a well watermarked JPG, is detailed editing (with Photoshop for example).
It can take a lot of skill and time to remove JPG watermarks.

You can of course, convert your watermarked JPGs to PDFs
Such PDFs would effectively be uneditable.
(Parts could be recreated with OCR).

Hi Eirman,

Thank you for the help - how do you go about putting a watermark on a JPG file? Also if the file we want to watermark is a DWG file, how can we convert it to a JPG?

Thank you,

John

Once you turn a DWG or a PDF into a JPG you lose all the benefits of the formats. All you have left are images, no vectors no fonts, nothing that you may need later on. You cannot return these into DWG or PDF and keep respective content unaffected. In essence the PDF is the only a PDF of an image.

To apply security to a PDF you need Acrobat Pro, go to File>Properties and select the security tab. Select Password security from the dropdown and a dialog will pop up where you can select the options you need.

If you scan your drawings, the output will probably be JPG or PDF

Do a search for watermarking software. There is big selection (some free).
Most have batch processing features which allows you to process 100's of JPGs at a time.
