Oh didn't know that. Could an infrared filter help in that case?

  In this case if it used infrared, sure. But you have to remember that humans can't really notice the high frequency changes in light. There's plenty of scope to encode data in visible light. I'm sceptical if this would be implemented it would be quite a negative selling point for mobile phone cameras. And I don't see why mobile phone manufacturers would consider implementing this functionality.
