PEER REVIEWED - SCIENTIFIC METHODS

IMAGE AUTHENTICATION PROCESS

Image forensic analysis is the application of image science and expertise to determine if an image or video is an accurate representation of the original data by some defined criteria, and/or the determination of the original source of the image.

NOT EVERY CASE IS THE SAME

FORENSIC APPROACH

PRELIMINARY EXAMINATION

This preliminary testing determines if photo forensics is necessary/possible before taking the time and using expensive equipment to examine the file. Our experts do not accept cases unless we are confident that an accurate forensic investigation can be provided to our clients.

CAMERA-ORIGINAL VERIFICATION

This step aims to authenticate the digital image as an authentic copy or camera original. Experts intently examine the presented materials to look for edits or alterations. A digital information test will determine if an image has been modified with an application such as Adobe Photoshop. These sorts of edits leave digital footprints behind that signal an alteration using photo forensics. Using reference samples, we can compare the evidence with a known sample to determine authenticity with the highest accuracy.

GLOBAL ANALYSIS

Image examination continues beyond the data embedded in the file using global analysis. Copying images, often done for use in court, can affect the quality of the picture globally. Formats such as JPEG or PDF can compress the image, which interferes with the pixels. As a result, this lack of quality will deem the image inauthentic because certain subjects in the photo, including people or vehicles, will be unidentifiable in the compressed file. 

LOCAL ANALYSIS

Local level analysis examines specific areas of the image to determine if local modifications have occurred which include cloning, stamping, morphing, compositing, light manipulations, or removal of information from a digital image. This error-level analysis essentially x-rays the images to discover manipulations.
