アプリケーションが構成された後、なんらかの変更があった場合に false を返します
それ以外の場合は true を返します。
Note: Use Application.genuineCheckAvailable along with Application.genuine to verify app integrity. Accessing the Application.genuine property is a resource-intensive operation, so do not call it during frame updates or other time-critical code.
You can use this as an anti-piracy check because it checks if the application was altered after being built. See iOS advanced mobile scripting and Android advanced mobile scripting for more information.
