Client wants to have online ebook store, so users can read books online only READONLy (without option to download them or copy content).

I assume that those books will be in PDF format stored on server (or it could be other format if there is some that is better for this task?!).

I was trying to find something in google about this, but without any luck. Probably, I was using incorrect keywords liek "displaying pdf without download option" etc. I know that ebook stores has some functionality like this.

Can you, please, give me some clues:

  • what is the concept, how this could be done (show content, but restrict users to downoad content)?

  • is it difficult task or there are some existing libraries (commercial or non-commercial) for this task?

The store would be written in PHP, but I can use other technologies if this makes it easier.

I understand that nothing is 100% for sure, I just need some ways to make it harder to steal for "normal" users.

I want to note that all content that client wants to publish is 100% legal for pubishing (clien has rights to publish those ebooks).

简而言之：在计算机上显示给用户的任何数据都必须传输到他们的计算机才能显示。因此，他们将在他们的计算机上拥有该内容并能够保留它。

你可能会想办法让这件事变得困难，但你永远无法做到这一点，因此没有多少出版商会授予你以这种方式出版的权利。
