Photo Forensics | Image Authentication Experts for Courtroom Use
What is Image Authentication?
Digital images used as evidence are only a reliable representation of the events when the court can verify them appropriately verified. Editing applications can manipulate digital images while concealing a judge’s and jurors’ ability to detect them. Furthermore, even uploading can convert or process images accidentally. When used in court, the uncertainty of an image’s authenticity is especially concerning. Our forensic image authentication services enable our team to discern if an image is authentic or altered. In other words, photo authenticity checks using digital image forensic methods like image analysis.

Why is photo verification important?
“Image authentication is the application of image science and expertise to determine if an image or video accurately represents the original data by some defined criteria and the determination of the source of the picture.” SWGDE Best Practices for Image Authentication
Image Expert Michael Primeau explains the role of an image forensic expert in court and the forensic photo analysis process in the video to the left.
Working with Mike and his team at Primeau Forensics was a five-star experience from beginning to end. First, their cost estimates were accurate. And the costs overall were well worth the excellent services and deliverables received. The team worked overtime over a holiday weekend to meet some of our unexpected needs. Mike testified in the trial of our case and was a stellar witness. Communication was good. I would give them six stars if I could!
We were in a bind on the eve of trial and contacted Primeau Forensics a few days before the we were to start. Mike worked tirelessly, even late at night and over the weekend to get us what we needed and based on his representations and expert opinions we successfully won our issue before the Court and proceeded to trial with one less issue to worry about. I can’t state enough about how satisfied we are with the service, attention and result we received. We definitely will be using this group in the future.
Stellar Service, prompt reply. They went above and beyond for me in analyzing some dashcam footage to fight a ticket. Very kind and helpful, great customer service. Cannot recommend them enough.
We worked with Michael Primeau who provided exceptional work in a timely manner. Mr. Primeau was responsive, proactive, and a pleasure to work with. We highly recommend Primeau Forensics!

Digital Image Forensics
Primeau Forensics offers image authentication services using the best practices with the highest accuracy for court use. Freeware tools can detect photo manipulation, but forensic tools combined with the ACE-VR methodology are the most reliable. Above all, the attention to detail combined with verification is the best scientific method to determine whether digital image evidence is genuine.
Forensic Process
Preliminary Examination
First, a forensic scientist assesses the digital image and look for any "red flags" to warrant an investigation. The initial evaluation examines information such as the device type and where the device originally stored the digital image. This chain of custody helps decide if further examination using forensic photo analysis is necessary and if specialized tools will help with the case.
Image Manipulation Detection
Second, experts carefully examine the digital information to detect traces of edits or alterations in the digital evidence. They also check the data and camera specs. An error-level analysis displays an X-Ray of the image to detect any faults.
Metadata Analysis
Thirdly, a digital information test is useful to detect traces of photo manipulation tools as well as image modification traces. Photo forensics can detect any digital footprints left behind from an edit. Reverse image searching is useful to discern if similar images to the evidence exist on the internet.
Global/Local Analysis
Next, the most in-depth analysis examines the entire image (global) as well as specific areas within the image (local). For example, copying images for court use can reduce the quality of the picture. JPEG or PDF formats compress the image, making it hard to identify people or things in the photo. However, photo forensics is used to look for signs of local changes like clone detection, stamping, morphing, light manipulation, or removal of info.
Device Verification Analysis
Generally, source verification is an effective way to determine if a photo is genuine. Experts may make a sample to compare with the analyzed image, considered the original image. The expert uses the same device that created the evidence to generate the most accurate models during the investigation. In most cases, an image has undergone alteration when the digital information between the sample and the evidence differs significantly. Undoubtedly, this is the most effective methodology for image verification.
