Embedding camera readable data on an image

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

Some scheme including watermarking plus image recognition, is the only way to go. Image recognition hit rates vary, but they don't have to be "very poor". However, a complete answer is a *huge* problem as this is an area of active research (or worse, at the intersection of multiple areas of active research). — dmckee --- ex-moderator kitten, Dec 25 '13 at 19:11
