rights protected photo on android

I've been tasked with writing an iphone application that displays a set of images (think开发者_运维技巧 powerpoint slideshow). The content of these images need to be protected from forwarding

this task seems quite simple with one exception - I'd like to prevent the user from taking a screenshot

it's not like i'm protecting the crown jewels here, so I'm not looking for military grade super ninja protection.

thoughts?

If the user has the Android SDK, they can take a screenshot. There is nothing you can do to stop it.

OTOH, without the Android SDK, there is no way to take a screenshot in Android.
