Marker Piracy Protection

November 28, 2017 - 7:51am #1

I realize that there is no 100% protection from piracy and that most games can be decompiled, the media assets copied, and even obfuscated code read.  But can Vuforia image markers be protected?

In our Unity/Vuforia AR game, we have image markers that are tied to physical products.  We realize that there will those that take photos of the physical products to recreate the image markers.  But can we protect the image markers in the game from being decompiled and viewed?  My guess is no, there are many tools out there for decompiling games.

But, do we even need the image markers in the Unity project?  In our game, we do not display the markers at anytime in the game.

Assets/Editor/Vuforia/ImageTargetTextures/*.*

Aren't they mostly for display and dev testing in the editor? Don't we just need the xml and dat files in the streaming assets folder?

Hello xpensv,

You are correct that the textures in Assets/Editor/Vuforia/ImageTargetTextures are for display and development. You can remove these textures and still have your Image Targets work, but please keep the xml and dat files.

I have confirmed this by removing the Mars assets from the Core Samples and deploying to an Android device. The Image Targets remained functional.

Thanks,

-Vuforia Support
