Embedding camera readable data on an image [closed]

Question

I have a set of images on a data set and I want to create an application(on android initially) so that the application would be able to take an image and match it with an image on my data set. I tried using image recognition algorithms but I had very poor recognition chances. Is there any way to unobtrusively embed data on the image itself such that when a printed version of the image is scanned by the application, it would be able to extract the embedded data? I need some direction in this regard because I seem to be punching in the dark since I haven't worked on anything like this before.

Thanks
