JPG Image File: Thumbprint Database Repository

Here is an idea.
Maybe someone has already thought of this already, but if not here it goes.

The idea is to have a keep and maintain a database repository of image files, similar to what the FBI has on file and very similar to a Universal thumbprint database, but strictly for image files.

This would be for the purpose of quickly deducing whether an image appearing on ATS, is authentic or a Photoshop fake.

Using an image file repository, one would be able to downlaod the image file and analyze it to determine whether it is authentic or NOT.

Example:
Original image

Note: Digital Camera thumbprint and date picture was taken



Same image modified with Photoshop 7

Note: Photoshop 7 thumbprint and original date retained


If possible, please post:

an original photo from any digital camera

a photo that has been modiified using ANY photo editing application

This can also serve a point of reference for those wishing to study image file formats.


Just a thought.

Thanks.
