Law in a Snapshot: Can You Use Filtered Images in Court?
Most image processing techniques present a compromise: enhancing something at the expense of damaging something else. For this reason, it’s generally very difficult to say which techniques are good and which techniques are bad. Their applicability must be related to the specific case and the parameters used. Filters are just tools, and as such, they can be used in the right way, obtaining better images, or in the wrong way, damaging the image quality or presenting wrong information.
CCTV appeals: Don't underestimate the importance of image quality
The simple task of getting an image can sometimes be a challenge so it is no wonder that people look at the shortcut and simply take a picture of the CCTV monitor with their phone. It is great when recognition is time critical but when it is not, then the correct acquisition of the original video will help immensely in any integrity or authentication case. With the UK sitting under the gaze of millions of public and private cameras, it is no wonder that in many cases, the best chances of identifying an offender starts with the image caught on CCTV.
There's More to an Image then Meets the Eye
When using images as evidence during a court case, the point of view it represents acquires a resonance much stronger than the testimony of a witness. This is even more true with video, as we may understand the dynamics even from the frames and any additional information which may be gleaned from the audio track. There are many tools available to modify pictures, and thus the authentication of images is of paramount importance. But even more importantly, we need to understand how much data there is in an image, in addition to what we can already see.

Digital images - trust must be earned
The science behind forensic image analysis is fast growing and constantly evolving. Even within the last 5 years, the ability to take a photo, manipulate it to tell a different story, and circulate the misinformation online has become infinitely easier. The advent of smartphones, convenient digital image manipulation software and easy dissemination of information is throwing up new challenges that investigators and forensic technicians must adapt to.
Fraud in Science: the Bigger Picture
Cases of fraud within published scientific research are on the rise, with several recent cases involving the falsification of images. Tools exist to carry out the analysis in line with the scientific methodology, giving the judge and in some cases the jury, a basis upon which to evaluate the full weight of the evidence. Consider it ironic, but if the right software is adopted within the legal system then the scientific method may just prove to be the answer to the current crisis facing scientific integrity.
All is not as it seems
Digital images are frequently used to provide supporting evidence within papers and reports, yet are not routinely submitted to any scientific process of authentication. In a world in which the tools to digitally manipulate an image are freely available, it’s no longer acceptable to simply take these images at face value says Martino Jerian.
Image And Video Forensics In Court: Forensic Science Is Not Forensic Fiction
Enhancing images for forensic use is not just about trying a few sliders and combining filters until you see something better. Are you confident the images you present within a legal investigation would stand up to scrutiny? And do you have the procedures in place to challenge digital evidence introduced by other parties?
Incidents of doctored images frequently appear in mainstream media where they incite cries of “fake news”. Unfortunately, security investigations are by no means immune to this phenomenon either. In fact, given the increase in the sources of digital images, the integrity of evidence in such investigations is at its all-time most vulnerable.
Why investigating digital video is such a 'huge pain in the proverbial'
With CCTV probably being the number one piece of digital evidence used in cases, many officers will have asked questions like, how do I get the footage; why is it not playing; or how can I get an image? It’s important therefore to understand why we have ended up here. Why digital video, specifically from the surveillance industry, is such a huge pain in the proverbial!
Investigating Image Authenticity
This article takes a look at two cases involving the authentication of digital images and the importance of the questions asked of the analyst during those investigations, and how authentication software has been designed to allow a structured workflow, and locate the puzzle pieces required to assist in answering those questions.
Only a matter of time until fake evidence leads to false convictions
With the rise of the digital age can experts trust that photographic evidence is legitimate? A growing number of forensic and counter-terrorism units are getting on board with pioneering image authentication software. Approximately a third of UK forces have invested in tech company Amped Software's products - including an all in one programme which can detect doctored images.
Seeing Beyond The Image
Martino Jerian examines context, content, and format of images. From the images and the context in which they are used we can obtain a lot of information that is not visible with the naked eye, and for what is visible with the naked eye, can we trust it? The process of authenticating an image is a mix of technical and investigative elements. This article looks at how to perform a complete image analysis.
Retrieving Evidence from CCTV
Acquiring evidence from a digital camera or a smartphone is more or less relatively easy to do. Images are usually in standard JPEG format and videos in MP4 or some other format that most players can read. But what is the best way to retrieve and handle CCTV footage to ensure it stands up to the scrutiny in the courtroom? There are numerous possibilities and it depends on where the video is actually recorded.
Exposing fraudulent digital images
We tend to believe what we see. But in the digital age, images are easily manipulated and this can cause problems for fraud investigators. This article describes how images may be altered and the techniques and processes we can use to spot pictures that have been modified. With the right tools and training, exposing doctored images in fraud investigations is now not only financially and technically viable, but urgently necessary.
The Importance of Using Images as Evidence
Are you really sure everything possible has been done regarding the proper use of images for investigations and if they have been exploited to their full potential? Are you really sure that images and videos have been properly validated and are not the result of some tampering? Was the image of sufficient quality to prove or disprove some testimony? Has the image and video been analyzed by an expert with the proper tools?
Trust? Can You Really Trust An Image?
If fake images are widespread on social and traditional media then how do we know it isn’t also affecting police and court investigations? After all, if members of the public are prepared to manipulate images for the sake of a few likes and retweets, what will they be prepared to resort to when the stakes are much higher?
Can you trust what you show in Court?
Is the Criminal Justice System naive to believe that fake images do not end up being displayed in court and presented as truth? Even if it is a rarity now, we need to think of the future. To start with, we must ask ourselves, “Can we rely on the image we see before us? Has it been authenticated?”

Who's the real end user?
It's not enough to install - and in the correct places - CCTV; you need to know what to do with the footage you gather. For one thing, as Dave Spreadbourough pointed out to Professional Security, often the real end user of the CCTV - someone investigating a crime or other incident - is using footage from cameras that were fitted for a different purpose.
