DIGITAL IMAGE AUTHENTICATION
With the rise of digital media, images have gained a large presence in court. Digital images can be significant evidence in a range of cases, but with lives on the line, this evidence needs to be an honest reflection of the events that occurred.
WHAT IS IMAGE AUTHENTICATION?
Digital image authentication is the application of image science and domain expertise to discern if a questioned 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. – Best Practices for Image Authentication SWGDE V 1.0 Pg. 4. In other words, it determines whether an image is real or fake. And Primeau Forensics’ digital image forensic services are performed using the best practices for image authentication within the scientific community.
Similarly, image authentication does not answer specific questions about the subject(s), object(s), or event(s) within an image, such as “Is a specific object present?” “What happened?” or “Where is the scene depicted?” These are all examples of questions answered through image content analysis. – Best Practices for Image Authentication SWGDE V 1.0 Pg. 4.
Images from a digital camera are not always reliable, especially as more people use photo editing software. That’s why digital image forensics is often necessary to determine authenticity. Thorough forensic image analysis can always detect whether an image was manipulated or not. Explore our various image investigation services below.
IMAGE AUTHENTICATION SCIENCE
The purpose of digital integrity verification testing is to validate the integrity of the image format. While performing this service, we examine the digital information embedded within the image. This will determine if the information is consistent with what we would expect to see from an original.
For example, a camera system creates an original recording when it produces a first-generation copy. An expert then performs forensic image analysis and verification testing. These procedures will tell us which recording is a copy and which is the original.
