    Hey,

    Just created a ebook and now it is being shared somewhere else on the internet. I got a PM from a guy telling me about it but he wouldn't say where he found it being shard just the links where the file has been uploaded.

    Now i want to know how i can secure my ebook and also stop it being shared (but i suppose they come hand in hand).

    hmm i think you can atleast make it so that you cannot copy the text in it but i doubt its pretty impossible to secure so that you can't give the file to another person. Also if you can read and type you can just read and and copy it word to word.

    Good luck

    There are ways to secure your work but this means the user to have to log in and have a connection on the internet. And even this is not 100% secure cause as long as someone has the username and password it can login.

    Hey Lewi! Haven't seen you on here in a while.

    Yeah i would say its pretty hard to stop someone from buying your product and reupping to mediafire or rapidshare or whatever. You could password protect it though. That might help

    Okay... but there are such things as those key's that people use to secure their program's too.

    Or maybe just a way to track who is sharing it and letting everyone know who buys it that they are tracked and i know there is something available to remotely shut down the ebook or whatever too.

    The oldschool method would be to create an executable and then just have it run a screen where it displays the text when executed. You then have it call the server with a keyhash on running so it has to be ran from the same computer it was sold to. Quite a pain for an ebook though...

    Maybe this will do what you're looking for...

    Code:
    http://www.secure-ebook.com/index.jsp
    I haven't used it and it's not free but it might be worth the investment.

    Could be, a talented coder could figure out how it works and make his own. ;)

    I think that bizcredit did something with his CSing guide. Maybe you should talk to him.

    I'm working on a couple of ebooks myself, and most of the monetization will come from embedded affiliate links. I figure this is a built in way of cutting my losses. The only other ways I know of is to make it inexpensive to begin with, and/or to make it an .exe . (Google it.) I don't think that is foolproof, either. Might as well stick with the pdf file since there is no un-crackable DRM.

    I'm on the lookout for something similar myself so be interested if anything useful comes up.

    One thing I did come across that might do the job if you're thinking of using pdf files for your book is this:

    http://www.setasign.de/products/pdf-php-solutions/setapdf-stamper/features/

    It allows you to amend existing pdfs using php code (so you could stamp it with some detail that identifies the customer) - haven't tried it yet though

    I didn't think you got much in the way of compression with zipping pdf's though - haven't had to for ages though

    Right - with you now - still, where there's a will there's a way - I'm sure there are other php libraries to zip stuff up too if needed - depends on how much you want to protect your goods though

    Ok i have a system called Download Guardian that secures any ebook (or software) so that it is 'locked' to one PC.
    Basically it grabs a ton of info about the PC it is being installed upon and then sends it to my database (encrypted, of course).
    For ebooks, they are 'locked' within an .exe file and cannot be directly accessed.
    The only way for someone to copy the book would be to copy the text, which would be laborious.
    System works by (customer end): customer buys product, goes to my Download Guardian site and registers for free. Ithen create a license for them (8 digit username & 16 digit serial code, random). Customer logs back in and accesses product (from a randomly generated dload link) and then uses username and serial to access product.
    Usernames and serial are not stored within the product, so sharing them is pointless, as they 'lock' to one pc and one pc only.
    That means even if they send the file to their mates with the username and password - they cannot use it.
    Let me know if you want more info.

    I Was thinking along those lines myself but you would want to give each
    individual copy a unique watermark so you could trace back the leak.
