[gentoo-user] [OT] Secure web document
Hi I work in the engineering sector where we issue documents that detail process methods on how to produce certain items of equipment. Recently we have produced some documentation that we need to be able to publish [in a form such as pdf] for use by our suppliers BUT we want to ensure that this documentation cannot escape out of our control. What I am wondering is, can a document be published to a website [for example] in such a way that it can be viewed and read but it cannot be either copied, downloaded, printed or the text extracted from it? Not in the spirit of open source I admit but in the world of manufacturing there is little honour.

Hi! Viewing / reading implies that the information has already been transferred (downloaded and rendered) to a client browser. So I don't think that you could totally prevent information extraction on the client side. You can make it rather hard though: 1. Use evil things like Flash. 2. Convert the information to a graphic format and use that as background image. No browser is able to directly download background images (in the moment). 3. Invent your own crypted text format and develop a viewer for that. *SCNR* the irony. But it seems you want to solve a organisational problem with a technical approach. That never works IMHO.

Thanks for the suggestions, the self code sounds like a fun project but I suspect my manager will want an off the shelf solution. So it seems like Adobe will be receiving some of our hard earned cash. [suspected it would go there] I agree with your point about organisational problem btw, the problem is that we do not trust our own suppliers. stuart ps. Apolgies for the off-topic.

So I don't think that you could totally prevent information extraction on the client side. Even if you prevent people from copying and pasting, you can't stop them from opening up nano and just typing a copy by hand, pointing a camera at the screen, taking screen captures, memorizing all the information and then telling someone, dictating it into a tape recorder... the best way to secure your files is to not put them on the Internet. Just print them out and hand them to someone along with a non-disclosure agreement. Or, a little trick I picked up from the TV show Ghost in the Shell. Convert all the text into barcodes and just let people's cyber-brains decode the barcodes. This technology, though, is definitely not ready for the general population... :-) -- Colin -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] [OT] Secure web document
loving the barcode suggestion Though I accept that simply someone taking the time to rewrite the text is impossible to stop, I just want to make it harder than click forward for them to get around. I was a little misleading with web in the subject I was more refering to electronic transmission [eg. email] or having a viewable document that could not be downloaded from a web server. From your suggestions I think a protected pdf with print restrictions and locked is the best option, so even if someone takes the time to rewrite it it wont have the electronic signature of our document so we can argue that it is an uncontrolled document and therefore not acceptable as a source of information. stuart ps. non-disclosure agreements are great but I suspect keep lawyers in business longer than we will :) On 6/14/05, Colin [EMAIL PROTECTED] wrote: Heinz Sporn wrote: Hi!

Well, printing and copying are going to be virtually impossible to enforce, because a determined person can just take screen shots of the document and print those. Heck, they can even run OCR software on the images to extract the actual text. My advice is don't piss off your users by trying to prevent them from doing something reasonable. They can always look for another supplier... I think a legally binding click-through agreement to not distribute the document, along with the appropriate proprietary-do not distribute notices in the document would be sufficient to keep honest people honest. If they are dis-honest, well, you are screwed regardless. -Richard -- gentoo-user@gentoo.org mailing list
