Startup Idea : Dermatoglyphics - Predict health issues

I know there is a vast subject around dermatoglyphics and how this is used in today's world in identifying one's strength and weaknesses in personality that will help a person succeed in their life. I want to understand how current apps are built on this subject and take it to next level where it can predict possible health issues that may arise in future.I also want app (algorithm) to provide possible recommendations for the treatment and collect vital information just by fingerprints. Using machine learning/AI algorithms in prediction.
