THE SUPATLANTIQUE SCANNED DOCUMENTS DATABASE FOR DIGITAL IMAGE FORENSICS PURPOSES

The ease of use and the capabilities of image editing tools has raised the challenges in the emerging field of digital image forensics related to scanned documents. Unfortunately, the universality of current methods and their applicability in real world scenarios have not been proven yet due to the absence of a standardized image database. In this paper, we introduce a novel test collection of more than 4500 images annotated with respect to each scanner as a useful tool for forensics investigators to test and compare scanner-based forensic techniques. It is an image database that contains document of various content scanned with more than one resolution with 11 different scanner instances of widely known brands. This selection is based on our latest work on the identification of scanners at the origin of digitized documents and is adapted to fit any source scanner identification technique. The SUPATLANTIQUE database is available for free to the research community and is intended to become a useful and a reference resource for researchers in this field.
