We are looking for someone to build us an iPhone application that at the most basic level would allow the user to:
1) User A would take a picture or upload a picture that already sits in the phone's album. These uploaded images would sit on a cloud server (Amazon S3 as an example) within a specific folder / category
2) Use some sort of an image recognition script to sift through the images in the folder and look for images with a specific identifier e.g. a number
3) The identified images with a specific number would be matched against of database of registered Users B. As soon there is a match, User B would get a notification and see the pictures.
4) All users should be able to browse the images if there was no match.
We can provide more specifics after the project is signed off.
Happy to hear your thoughts.
