I thought of a great idea for an app. This idea obviously isn't something you could make in a day, maybe not even within a year.
My idea is to make an app where you could snap a picture of someone's face, then you can use a facial recognition algorithm to find that person's twitter/facebook etc.
I personally think that it is possible, but you wouldn't be able to use that person's profile picture on their facebook/twitter. The website, or the app's website, would have to create a database of faceshots of the individual that is uploaded by them that would only be used for locating their social media.
What are your thoughts?
