issues with Acrobat

 »using Acrobat ebooks or other suggestions
 
trimpo Hi there,
            I produce / publish books via a print on demand print company.. I use Acrobat to create the PDF files they prefer.
            I'd like to offer some of these publications in eBook format and it seems practical to use Acrobat to do so.
           However, I'm confused and perturbed by Adobe eBooks mode of delivery and the demands made on my customers.
           I just want them to be able to download and read their eBook with the minimum of fuss and for me to have basic protection against the copying of my publication.
              Apparently, and I may have misunderstood this, but my customers would have to register and then use Acrobat Pro to read an Adobe eBook.
             I'd appreciate some help - as you can see, I'm a bit confused.

             Thanks in advance.

If you are concerned about PDF security then you should take a look at my HYPrPDF security system.

In a white paper report about PDF security, Bryan Guignard explains how he was able to remove all security restrictions almost instantly and how easy it is for hackers to access, modify and transform any PDF document.

Using readily available "hacker" software -- The bottom line is:

1) Once you distribute a PDF file, the Master Password and restrictions can easily be removed.

2) Even when encrypted with a User Password; the Master "OWNER" Password, restrictions, User Password and encryption can be removed if you give anyone the "USER" Password.

3) PDF eBooks with expensive online DRM security (such as, but not limited to Web Buy, EBX, DocBox) offer no additional security - all security can be removed.

Therefore; when you distribute your PDF document and issue anyone a "USER" password the PDF file can no longer be considered secure.

HYPrPDF is the only product available that can fully protect a PDF file. Why? HYPrPDF uses invisible "OWNER" and "USER" Passwords.

When PDF files are encrypted with both a Master "OWNER" and "USER" password, the security is ultra strong and the PDF files are fully protected. However as soon as you issue a "User" password (so the customer can open and view the document) the file is unencrypted and it can be hacked. The simple act of giving a customer his "USER" password makes the PDF file vulnerable.

HYPrLock/HYPrPDF Security Software actually encrypts the PDF file with invisible "OWNER" and "USER" passwords. When an authorized customer tries to open the document, HYPrPDF enters the correct invisible password to open it. The customer never has access to the "USER" password so the PDF file can never be unencrypted outside of the HYPrLock/HYPrPDF system. Hackers can never access the PDF file because they can never get their hands on the invisible "USER" password.

HYPrLock also provides all of the e-commerce security you need when you market your PDF eBook. You can even distribute your PDF eBook on eBay (as a digital download) with full anti-share protection.

trimpo Hi rlemire,
               Many thanks for your reply. As I said, I really only require basic security. My real issue is with the apparent demands made on potential customers to enable them to read an Adobe eBook and also the requirement for me to use Adobe's content server. Using Acrobat could streamline the process of creating both eBooks and the digitised files needed by the  company I use to produce hard copies.

rlemire trimpo;

Maybe I misunderstood your question. I thought you were looking for something better than Adobe's Content Server. Something that was easy for you and your customers to use, didn't make unreasonable demands on potential customers and streamlined the process of creating PDF eBooks. (and maybe didn't require monthly fees)

I'm sorry if I was mistaken. Maybe you should explain exactly what "apparent demands" you have an issue with and what "requirements" you object to with Adobe's Content Server. Also it might be helpful if you explain what you mean by "basic" security and why you are not concerned that anyone can easily hack into your PDF documents and remove all security.

Although the Adobe Server promises eBook security, what they are really talking about is distribution security. That means they can control the distribution of an eBook and make sure that only authorized customers can download and access your eBook or PDF content. What they don't mention is the fact that once you distribute your PDF document and give anyone a "USER" password to open and read the document it is no longer secure. The very act of issuing a "USER" password makes the PDF file vulnerable to hackers who can easily remove all encryption and security. for more information on PDF security check out this white paper on the subject.

HYPrLock, on the other hand, offers not only better distribution security (less expensive - without monthly fees), it's also the only security system that uses "invisible" USER passwords. The HYPrLock security system with HYPrPDF can prevent any breach of PDF security because customers never get their hands on the USER password - they never even see the USER passwords... so the USER password can not be "shared" or used by hackers to remove encryption or PDF security.

BTW: Just because Activ E-Book is an eBook Compiler doesn't mean you can't distribute Acrobat documents. HYPrLock and HYPrPDF were designed to work with Acrobat and other PDF files (however they were created). When you open a PDF file packaged as an Activ E-Book it opens in Adobe Reader just like a regular PDF file.

trimpo Weird! I posted a reply to rlemire and it was shown on the forum as posted. Now it's vanished!
Point is rlemire, because of the nature of my publications, I do not really need cast iron security. I really only need to discourage my customers from printing copies.
My problem is that Adobe, apparently, makes certain demands on my potential eBook consumers which I'd rather avoid.
I may have this wrong but, as far as I can gather, they would have to go through a registration process and they would need acrobat pro to actually read the Adobe eBook.
I simply want my customers to be able to download their eBook (and a bundled reader if necessary) and read it 'straight off the bat'.

If you have no concern for security, simply create your PDF file using Acrobat ( or any similar product) and disable printing in the PDF security setting.

Next upload your PDF file ie "myInformation.pdf" to your web site and send your customers a download link. This file will open with the common Adobe Reader.

There is no reason to use Adobe's Content Server. It's only there to give PDF authors a very expensive false sense of security.

However, If you want an inexpensive security system that automatically adds password protection and real PDF security check out HYPrLock..

trimpo Many thanks for your advice Ron.

Neenah13 Yes, I'm not understanding why anyone would need Acrobat Pro to read an ebook when, as stated above, Acrobat Reader is free.

I don't know anything about the Content Server. Guess I'll go check it out so I know what's what about it.

Since I'm into fiction mostly, I don't worry a lot about protection. I allow print, I don't allow copy. I allow the same in my ebooks compiled with Activ Ebook Compiler.

Most people aren't looking to steal your content. Most probably won't give it away, either.

If some determined person passed my stories around, my dream would be that it got shared with a big publishing house editor who, after reading my stuff, offered me a six figure deal. And then signed me up for several books in another awesome deal. Probably won't, but it is a nice dream.

Crazy, I know, but there it is.

Oh, I _so_ like the idea of being able to disable an ebook when a refund is asked for!

Librum rlemire

Has HYPrPDF been tested with PDF Password Remover?  http://www.verypdf.com.  

We have a new senerio.  While we use Activ for our 'in-house', we also have standard pdfs, that we host.  Or did, until the content theft became too much.  I once tried a pdf under Activ only to observe that the save as pdf function was still active.

As these pdfs are page scans, jpgs, I would have to create the html linkage for each to use under  Activ.  Very time consuming.

Any pointers / ideas, etc would be welcomed.

rlemire Librum;

If you look at the PDF Password Remover website you'll see they have a limitation that states:
"If both user and owner passwords are unknown the PDF Password Remover will fail".

The advantage of using HYPrLock/HYPrPDF is that both the "User" and the "Owner" passwords always remain unknown, invisible and hidden from everyone (including the author). This means that PDF Password Remover (or similar products) would not be able to crack HYPrLock's Ultra PDF protection.

If you author PDF files or documents, HYPrLock/HYPrPDF can prevent hackers from opening, editing (changing), printing, selecting text and graphics (and copying them into the Clipboard), or adding/changing annotations and form fields. HYPrLock protected PDF files can only be opened by the HYPrLock program.

Hackers might be able to save a HYPrLock protected  PDF file to a different location but they would never be able to open it.

I'm not sure I follow your statement "I would have to create the HTML linkage for each to use under Activ".

With HYPrLock your PDF document is encased in a protective Activ E-Book/HYPrLock "shell" (controlling access to the document) but your document is opened in the Acrobat Reader program.

Librum rlemire, there are also other ones who eat both passwords.  (sigh)


I like what I see, rlemire.  The trial version worked fine.  But not the registered?  There seems to be a problem with javascript.  I am working on it.  Most likely a mistake on my part.

Question, from another, using your pdf encrypt.  Is there a way for him to set the requested password, to say 'sesame'.  He does NOT need the other portions.  Let me walk through.  He has the pdf, runs it through the pdf encript with the password set to be 'sesame'.  Then before he wraps the pdf in Activ, he brings up the pdf under Adobe, and it asks for the password.  Satisfied, he then does the Active wrap.  Under Activ, an index file comes up, stating that if javascript is not working properly on the users computer, use password 'sesame'.  This way he provides security, as the pdf can not be broken out, even with the password, and the non-javascript users are also supported.

rlemire Sarah,
of the Librum..

Adobe's PDF format is widely recognized as being extremely secure as long as both the User and Owner password is unknown. Unfortunately you need to give a customer a User password so he can open the PDF file. This reduces the PDF file security to practically zero.

With HYPrLock the customer is never given the User password, he never even sees the User password. HYPrLock keeps both User and Owner passwords invisible so PDF security remains Ultra secure.

Do not be confused by claims some companies make about being able to remove both the User and the Owner passwords. While this may be technically correct, these program still need one of the passwords. For example if they have the User passwords they can recover the Owner password. If they have the Owner password they can recover the User password.

That being said there is at least one company that offers a "Brute force" solution. They say they can crack a PDF file in about 3 days with a powerful computer. However this only applies to older PDF files protected with 40 bit encryption. HYPrLock uses 128 bit encryption this means finding an 8-character password by "brute force" could take 20 days or more.

I'm not exactly sure what you mean by your question of the 'sesame' password. The purpose of Ultra HYPrPDF security is Ultra security. You do have the choice to allow printing but that is all. There is no way past the security system. If you want to allow other access privileges to your PDF file (other than printing) you'll need to find a different solution than HYPrLock.

Your concern about people without JavaScript is pointless. If they don't have JavaScript then HYPrLock won't work or allow them to open the eBook anyway.

Furthermore, as you might know, Activ E-Book (and HYPrLock) use the Internet Explore browser engine for internal functions. There seems to be some confusion about JavaScript disabling however. It appears disabling "Scripting" in IE only disables "Scripting" in the browser, not in external files. So using JavaScript in an Activ E-Book might not even be an issue.

PS: I forgot to mention that HYPrLock not only uses 128 bit encryption but also uses 9-character passwords (random number and letters) so "brute force" hacking would probably take more than 30 days with a powerful computer.

BestEbookTrade Why dont U try to add a password to Ur PDF ebook.
I think is a good and simple way to get secure.
Any comments?

Posted on: 10:43 am on February 21, 2009
rlemire BestEbookTrade;

If you check around you'll find out that simply adding a password (or even two) to a PDF file does not make it secure. Why? Because as soon as you give out a password to someone (so they can unlock and view it). They can share the password with family, friends and PDF *h*a*c*k*ers. (**** ****s)
