Digital Image Forensic - Image Forensics: Authentic



Is it real?

One of the most important questions to be answered by digital image forensics is about source identification. Based on device specific parameters we identify the source, e.g. camera or smartphone brand and model. – The average detection rate of a single method is about 95%. By the combination of methods we reach detection rates up to 98% and more.

Digital images are often tampered to give us a visual evidence for a false allegation. As a first step, we verify the authenticity and integrity of digital images. In case that images are not authentic (eg. altered or manipulated by the use of image editing software) a mainipulation detection will follow as a second step.
