Igital Image Metadata and Exif files Forensics

First Iad like to have one paper or more about the identification of the metadata and the EXIF files
Then, Iad like to have a paper about the metadata of the digital image and how it can be used to identify the location of the captured picture, also in how we can use the help of the common places that can appeared in the picture to tell the location of the picture, in order to tell that a group of pictures were captured in the same location and probably by the same person. that is different than the identifying the digital camera by its serial number , we here like to identify that location of the images to identify the location of the missing people that might appeared in the image. for example these process can be used in the child pornography criminal case.
