Startup Idea : Lost and Found app

When you lost valuable items or you yourself found something that is not yours. My idea is to make an app for this..maybe if someone found the item he can post information about the location found, time, description(color, quantity etc.) to the database, the same with the person who lost his item will post details.. then the app may do matching of the claims and will notify both user when there is a match(percentage limit i think to match) so well they can talk about it. Or maybe be used on Lost and Found Centers. =)
