Locking and security

acpeter Hi Folks!
Using Active for all of our eBooks. Works great. Here's what we're trying to do.

We have a web page that's set up to let a customer enter a discount code. We make that page available using <iframe> tag in an eBook. Right now, the eBook is only 2 pages. The index is a short intro, to explain that the book only opens one time. The second page (that is the one we want to protect) includes the iframe to the web page.

So, how do we do this. We have tried different combinations, using simple 123 password, etc. Seems that we can not get this to open just ONE TIME, and then stop opening. Maybe we've got the wrong pages password protected? Not following this... sorry.

Any ideas?
Thanks in advance!

acpeter Hmmm.... no replys? That's unusual here.
Let me put it this way. I want to make a simple 2 page book. I want the book to open to PAGE A, but only one time. Then, when the person tries to open a second time, they go to PAGE B, which will tell them that the book is expired.

How can I set this up? Which pages get protected?
Your help is appreciated!

EBookCompiler I'm guessing (or maybe it's just me) - but I don't think anybody understood the question

I've read it, including the clarification, several times, and I still haven't been able to understand what you are aiming for

acpeter Sorry for taking so long to get back here, but we finally figured out what we were doing wrong (duh).

The project was to have a simple ebook. 2 pages. We wanted it to open ONCE. If the person trys to open it a second time, he gets to the PASSWORD page.  Basically, at that time, the book is locked and done with.

The reasoning is this. We use electronic coupons. We let a potential customer download the discount coupon which is  in fact an eBook. The page that opens is actually an iframe to a page on the site. The reader enters his code and gets a 'thank you'.

Our cart system calculates the discount we provide on a cookie. When he completes the sale, the final page also clears the discount cookie. Therefore, it's important to allow it to only open one time. Otherwise, the customer could re-register the coupon and keep getting the discount.

Hope that clears up the original question. We were just not reading the selection (in the compiler) to reset the book. It works just fine now! Great software!

gomo64 Hello. I am new here and I would like to add my two cents here.

I think you are right that if you set the ebook to open once before it asks for a password, then your problem is solved.


how about if the customer open the ebook in a different PC? is't the ebook is going to open again (once) for this new PC?

Sorry to bother you but I have to think as a pirate to protect myself.

Let me know if I am right so we keep looking for an answer.

Storyman Hi Gomo64,

Yes, you are right. The ebook can be opened on a second computer and 99% of the time that is what you want. What I understand is that you are concerned about the other 1% who open it on a second computer for some nefarious reason. This raises several questions.

From a practical business sense how much are you willing to spend to prevent this from happening? Are you concerned enough to inconvenience the other 99% by having them log onto the internet? Even then it isn't a foolproof that you can prevent it from happening because the only two ways you can verify the user is either through their IP address (which changes frequently if they are on dialup or use a dynamic IP address) or have them log in (which means they can make up a new username/password. Not to mention all of the time and trouble to implement such a system.

Maybe if you explain what damage you expect to be done by the user installing the ebook on a second machine your concerns can be better addressed. Maybe, I'm not fully grasping the danger involved.
