Protecting your images from being saved.

[sarika]

Hi all
I am making a website related to uploading art pieces. My requirement
is to protect art pieces from being saved by any means.
I dont want my images to be save in temporary internet files,not in
cookies.
Also the page should not be saved as in any browser. and Right click
on image should be disables . Also no one can take the printout using
print screen.

Please help me as it is urgently required.

If you are going to send images, there can do whatever he wants with it,
and there is *nothing* you can do about it. You can disable cache, you
can disable right click, but user still save the image or download it
directly.

Typical solution is to place watermark on the image. Take a look on the
stock image retailers on how they do that.

Easy: don't put your images in a webserver in the first place. That's the
*only* way to prevent copies to being spawned.

Yea, even unto doing a cut and paste of the screen image. If it can be
displayed, it can be nicked. I know, Ive done it ;-)

Yes. Simple job with e.g. Corel Draw. Put something over it with a high
degree of transparency, and then save as a highly compressed Jpeg.The
art is to get it nice enough to tempt them to buy it,but not so nice
that they don't need to.

This is a PHP group, so I'll say that creating a .png watermark (something
white with a great deal of alpha) and using imagecopymerge( ) will do the
trick, and it can be done programatically whenever a new image is added to
a DB. Also, remember that imagejpg() can be used with a specified quality
parameter.


Adding steganography to the image should be fun, though...

Forget it.

Once an image is displayed in a browser it is on the machine and can then be
copied. All you will do by disabling all the browser functions such as right
click is to make your site thoroughly terrible to visit.

Then don't put them on the web. Yes, you can cripple some browser
functions, which will hamper the mentally-challenged users of those
browsers, but there is no way to prevent saving "by any means."

I dont want my images to be save in temporary internet files,not in
cookies.
Also the page should not be saved as in any browser. and Right click
on image should be disables . Also no one can take the printout using

There is no technological way to do that. Even if you were to go as
far as to implement your own data transfer protocol that would only
allow authorised clients to connect, developed your own browser with
authentication keys that tied every copy of the software to one of
your subscribers and designed the browser software to disallow
anything except the viewing of images, even assuming you could do that
in a way that could not be circumvented (and better folks than you
have tried and failed), what's to stop somebody from hitting the print
screen button, copying the display to the clipboard, pasting it into
an image editor and saving it off anyway? The absolute best you could
do is make your site so obnoxious to use that nobody will use it.
(Technically that would mean nobody was stealing your images, but only
because nobody was even bothering to look at them). Watermarking
might be a better choice but if the watermark you apply is obnoxious
enough then it will have the same effect of simply driving your users
away.

Your only option would be legal, by requiring people to become members
of the site to view anything, and requiring them to agree to some kind
of EULA to sign up. Then you could in theory litigate against anybody
using images on the site contrary to how you want them used. But that
approach is expensive, lawyers don't work for free. And if your site
has any kind of success at all the instant you try to sue one of your
users for saving a copy of an image on your site the online press will
completely vilify you.

Realistically, you can either accept some image theft will occur and
live with it, or you can not publish your images on the internet.
Those are your only choices.

You have only one good option: You high transparent image on top of
the image. This way many cannot copy it.

and what about another one: using flash for displayig image. I am not
sure. But this way your site will become very heavy.

You can still do a screen capture.

The people who really want to copy it know how to do so. The average
user doesn't matter here.

Flash would just make it worse and cause more problems for some people.

First option can be defeated by going through the browser cache,
second method can be defeated with a flash decompiler, both can be
defeated with the print screen key.
