This plugin for Unity Android Pro 4 provides Digital Right Management (DRM) integration with the SamsungApps’ Zirconia.
Samsung's application store for Android devices uses a proprietary DRM known as Zirconia. This plugin provides the means to access Samsung Apps’ Zirconia functionality from Unity, which will allow you to verify the purchase license against the device running your app and protect your game from fraudulent sharing.
The plugin is well-documented and fairly simple to import and implement in any Unity project. A sample scene is included with a single script demonstrating the functionality.
