Dating image and video material using OSINT – forensically verifying the time at which visual content was recorded

In addition to embedded metadata, visible environmental features such as weather conditions, vegetation, the pattern of shadows or recognisable events can also help to date image and video material.

Enquire without obligation

This method is particularly relevant when embedded timestamps are missing, have been removed or need to be checked for plausibility.

Our services

We analyse visible temporal indicators in image and video footage and cross-reference them with independent, publicly available reference data, such as weather records.

Typical areas of application

•Verification of the alleged date of recording
•Detection of incorrectly dated image or video content
•Supplementing geolocation and metadata analyses
•Support with the verification of press material and evidence
•Judicial and non-judicial expert reports
•Cooperation with solicitors and the media

This is how chronological ordering works

Visible temporal indicators are systematically identified and cross-referenced with independent sources such as historical weather data or known event data in order to narrow down the plausible time period in which the image was taken.

Why is the chronological context relevant from a forensic point of view?

The verified time of recording can be crucial in correctly placing submitted image or video material within the chronological sequence of events.

Furthermore, refuting a false claim regarding a date can be an important indication of deliberate misrepresentation.
