A platform that uses artificial intelligence to look for people whose face resemble yours.
People who want to use the platform will do the following:
Register with their details
Upload pictures of their faces from different angles
Authorize the app to search for people with similar symmetry
If the search is positive, send a message to the person(s) and strike up a friendship
For this AI to work, it will need access to a large database of pictures. While the people who use it will provide some images, it won't be enough. The AI will have to trawl social media sites, especially picture-heavy ones like Instagram and Snapchat.
Obviously, there is the issue of privacy to consider. I believe this can be solved by ensuring the app provides you with no information except when it finds a match.
Once upon a time, someone approached me at an event and talked to me like an old friend. I was puzzled and asked if we had met before. Apparently, they had mistaken me for someone who had attended the event the day before I was there. I have experienced similar scenarios on two or so other occasions.
I sometimes wonder if there are other people in other places, maybe other races, who look like me. If that is the case, I will like to know. I will also like to be their friends and learn about them. Hence, this idea. I think it would be fun, if nothing else.
