You can set your own user-agent string

http://developer.android.com/reference/android/webkit/WebSettings.html#setUserAgentString(java.lang.String)

Something like this

yourWebView.getWebSettings().setUserAgentString("Cool String to be parsed");

Then in your HTML you can catch this UserAgent string. In JavaScript is

navigator.userAgent

If you want other languages to manage it you can do it in PHP or Python to make it server-side.

But if you want true security... there is no a safe way. A kid can also emulates your webview's behaviour.
