Common questions
How does OpenMFC support a court-admissibility argument for a deepfake-detection tool?+
A tool's performance on OpenMFC's standardised, independently curated benchmark gives an expert an external, reproducible accuracy figure to cite, rather than relying only on the vendor's internal testing, which speaks to the technique's known error rate under Daubert-type factors.
Are OpenMFC benchmark results directly comparable to a tool's performance on real casework media?+
Not necessarily. Benchmark datasets are curated and may not fully represent the compression, editing, and platform-specific artifacts found in real-world case media, so an expert should note that gap when applying benchmark accuracy figures to a specific exhibit.
What kinds of manipulation does OpenMFC evaluate detection of?+
It covers a range of media integrity issues including splicing, copy-move manipulation, and increasingly synthetic or AI-generated content such as deepfakes, tracking the manipulation types the programme was designed to detect.
