Looking for: Designer, Developer
More than one person can bear the same names, but not more than one person  can have exactly the same face except in some cases which is little. 
Also, the probability of more than one person with same face, same name, wearing same clothes, being at the same place or taking a lookalike snapshot is low.
With the level of amazing technology available, I think we can develop an application that searches for people by images. A user uploads an image and clicks the search button. The application then crawls the Web searching for names associated with that image.
I really think this can be deployed as an anti-fraud tool for most people who go into dating online or business contracts online and fall prey.  When an image search returns with more than one name which clearly shows no connection, then the user can confidently conclude something isn't right.
