Let's face it.
If you put a lot of hard work, effort, time and maybe even money into writing a high quality, valuable eBook the last thing you want to worry about is someone stealing it.
You don't want to be plagiarized, but even more you don't want people to be able to distribute your book without paying for it.
Otherwise you won't be able to make any money.
There are several ways that you can secure ebook.
It all depends on the software you purchase to do so.
You can create ebooks that cannot be printed, cannot be highlighted, or cannot be copied.
In this way you can ensure that you information cannot be easily duplicated or shared.
One way you can attempt to stop distribution of your eBook without payment is to password protect the book.
This will make it impossible for anyone to get into the file without the proper password, which you supply only after payment.
The downside to this is that many people will not go through the trouble if they cannot preview the book.
However, if you want to keep your eBook from being distributed at all by another individual you can purchase a specific secure eBook software package.
This software will lock your PDF document using encryption software.
The book will then have to be activated with a code that you provide after the book has been paid for.
If the book is distributed without payment, only a portion that you specify will be visible.
Again, the book will be locked down and it will not be able to be printed or copied and pasted unless you specify these privileges.
