Adobe After Effects plug-in developer (C++)

We need a plug-in developed for Adobe After Effects that has 2 major components. 1. There will be an overlay placed on video that darkens and brightens in a random generated pattern that isn't visible to the human eye but can be picked up by a smartphone or tablet camera. Then that pattern is translated into data for an App to pull something from a database. This link below is an example of exactly what we need to accomplish that was developed by Fujitsu with their own software but we want to accomplish the same thing using an After Effects plug-in.

This works the same manner as number 1 above but utilizing audio instead of video overlay. This is so if for some reason the smartphone or tablet camera is to far away from the screen or isn't working properly the audio will be a fail safe to still pull the data from the database to be displayed on the app. This will basically work the exact same way the "Shazam" App works for recognizing audio. There is a couple more detailed items to go along with the above 2 things but If you are able to accomplish the above 2 items it should not be a problem.
