We are a small nonprofit that works with the homeless in Dallas. We use a custom Filemaker solution to track details on almost 7,000 homeless individuals. We would love to be able to use facial recognition to help us identify people. Most of our homeless friends do not have any form of state ID.
We take photos of all of them in Filemaker with our iPads. These photos are stored on our secure server as jpegs.

For example, we take a photo of John Doe. Is he already in our system under 7 other names? How can we help identify individuals (based on the name they give us) and insure that they always use the same name?
