I've been looking around for a way to prevent my web-users from printing values that I'm not legally allowed to let them print, but have not had much luck. I'm wondering if anyone here has found such a thing.
What I'm looking for is a HTML pluggable control that would render text to the screen while preventing copy-and-paste, screen-capture, and printing. I'm looking for a commercial or open-source solution, rather than suggestions on how to development one, as I wouldn't have time to write it.
For example (using Windows terminology, but looking for something cross-platform/-browser) I could imagine this being done by having an ActiveX control that renders straight to the graphic-driver's memory through DirectX (rather than a Windows' device-context). This would prevent it being passed on to the printer, appearing in a screen-capture, and no copy-and-paste. I know it wouldn't prevent memory-dumps/-hooks or photography--actually, if the control could prevent these too (like adding some water-mark pattern that is readable on screen, but due to shutter-speeds and resolution, makes photographs illegible and memory-dumps difficult to decrypt) that'd be cool too.
