Making available locked documents with a sunset.

[Oatmeal]

Hello,

I need to make available a document online for review. I need to prevent the viewer from copying, printing or using save as functions. After 10 days I need them to no longer be able to view the document.

Originally, I was leaning toward PDF, but that seems too easily beatable.

Any ideas?

It's hard to let them display something on their screen that you want to disappear from their screen later. Obviously they can take screen-captures and record it for themselves.

Ditto on printing; anything on my screen I can make come-out my printer.

The documents in question are rather large (about 300 pages). I know I can't stop screen shots, and if someone wants to do 300 screen shots then they beat me.

Microsoft has a new file display format out that you might be able to use for this, it's their PDF killer so authoring tools may be available cheap.
