What does an image or video appraisal consist of?
Computerized image and video forensics is a technical investigation that allows for the analysis, authentication, and certification of visual content presented as evidence in a legal proceeding. The process includes metadata verification, tamper detection, source device identification, compression, cropping, or editing analysis, and comparison of visual elements.

Frequently asked questions about image and video appraisals
Detecting whether an image has been manipulated requires a thorough technical analysis. Metadata (date, device, editing software), compression patterns, borders, shadows, visual inconsistencies, and digital noise are reviewed. Comparison techniques are also applied between images or with original versions. Computer experts use forensic tools that can identify modifications even if they are not visible to the naked eye. The goal is to certify whether the image is original, has been altered, or has been presented in a misleading manner. The entire process is documented in a legally valid technical report.
Image and video expert analysis is common in cases of harassment, extortion, digital violence, labor disputes, reputational damage, accidents, fraud, illegal recordings, or false evidence. It is also useful in disputes between individuals or companies where images or videos are presented as evidence. The expert’s goal is to demonstrate whether the content has been altered, manipulated, or can be verified as legitimate. In many trials, the technical analysis of a recording makes the difference. A clear and well-founded report can strengthen or completely invalidate visual evidence.
Any individual, company, or lawyer can request an expert report on images or videos. It’s not necessary to be in the middle of a legal proceeding: the analysis can also be performed preemptively, as part of a private investigation, or to defend personal or corporate rights. The expert report is confidential and is delivered in a professional report that can be used in court if necessary. We have certified experts, experience in digital audiovisual content, and a certified methodology to ensure the validity and objectivity of the analysis.
A video can be fully valid as legal evidence as long as its authenticity is guaranteed and it has not been tampered with. To achieve this, it is essential to preserve the chain of custody and have an expert report prepared by an expert. The expert analyzes the integrity of the file, the continuity of the recording, and any edits, cuts, or added effects. The technical context is also assessed: source device, format, date, and location. This analysis allows the video’s content and legitimacy to be certified in court. The expert report is key to its admissibility as evidence.
