I know this question is silly.
But as per our intelligent Client request, I am not able to answer his question. Any one help for this.
We are building a online tutoring site. where it contains pdf, .ppt, .doc formats files are uploaded for reading as course materials. His (Client) request is that user can read all the contents but they must not download the materials and use this.
That is all the documents must be opened in their browsers.
Is it possible? Any other ideas?
Explain to your client that the only way for a document to appear on a user’s computer screen is for the document to exist on that user’s computer.
In other words, viewing a document involves downloading it. Even supposing the software on the user’s computer somehow makes it impossible for the user to directly manipulate an electronic copy of the material, the user can take out a digital camera and take a picture of the screen.
There are ways to make it difficult for the user to save a copy of the file. However, it’s likely that this will do more harm (frustrating users) than good (preventing theft).
Some users may want to peruse the material at times when they do not have an internet connection, or may want to copy it onto their mobile device (for instance), but accessing the internet on their mobile device is expensive so they would like to do the download on their computer.
