Digital media forensics

Manual, evidence-led assessment of potentially manipulated images and videos.

Your material is examined by a human analyst, layer by layer. Automated tools may assist with screening, but this platform issues no automated verdict — the conclusion, and its limits, are written by the examiner.

  • Originals preserved byte-for-byte
  • SHA-256 recorded on receipt
  • Private storage, never published

A detector output is not an assessment

Automated classifiers return a score. An evidence-led examination explains what was observed, how it was tested, what it supports and what it cannot establish.

Automated detector

  • Returns a probability or a label
  • No account of the method used
  • Fails silently on re-encoded or cropped media
  • Cannot weigh provenance or context

Evidence-led human analysis

  • Documents the material, method and observations
  • Separates technical indicators from corroborating evidence
  • States professional opinion in measured terms
  • Names explicitly what cannot be established

Supported material

Three service types, each with a published turnaround and file limit. Pricing and current turnaround times are listed on the services page.

Image assessment

Single or multiple stills, examined for structural, compression and localisation indicators.

Video assessment

Frame-level and temporal examination, including audio-visual synchrony where relevant.

Urgent priority

The same manual method, scheduled ahead of the standard queue.

The workflow, end to end

Every stage is recorded. The upload link is issued only after payment is confirmed server-side, and evidence never passes through the payment provider.

Layers of examination

One frame is inspected through several independent planes. Agreement between layers strengthens an indication; disagreement is reported as such rather than resolved by assumption.

Evidence handling

Files are stored in private buckets with no public URL. Nothing is published, resold, or sent to third-party AI providers. Retention is time-limited and deletion is logged.

Preserved originals

No re-encoding, conversion or metadata stripping at any point.

Cryptographic receipt

A SHA-256 hash is recorded when the file arrives and shown back to you.

Scoped access links

Upload and download links are single-purpose, expiring and revocable.

Time-limited retention

Evidence and reports are deleted on schedule after the case closes.

Synthetic sample values. Your file is never re-encoded, and its hash is recorded on receipt so any later alteration is detectable.

Technical and legal limitations

Read this before purchasing.

  • Manipulation cannot always be established. Heavily compressed, re-encoded, cropped or screen-recorded material may carry no reliable indicators.
  • The assessment is a professional technical opinion. It is not legal advice, not a court appointment and not a substitute for a law-enforcement investigation.
  • No accuracy figure, guarantee or definitive proof is offered, and none should be inferred.
  • Findings apply only to the material submitted and the questions posed at intake.

Frequently asked questions

Does the platform detect deepfakes automatically?

No. The platform handles intake, payment, secure evidence transfer and delivery. The examination itself is performed manually by the analyst.

Will I get a definitive yes or no?

Only where the evidence supports one. Many cases end in a graded indication together with a clear statement of what could not be established.

Do I need an account?

No. Your case is reached through a private link tied to your case reference and email address, and links can be reissued if they expire.

Is my material used to train anything?

No. Submitted evidence is never published, shared with third parties, or sent to AI providers.

When is the upload link issued?

After payment is confirmed by the payment provider's signed webhook. Evidence is never sent to the payment provider.

How long is my evidence kept?

Only for the retention period stated in the retention policy, after which files are deleted and the deletion is recorded.

Submit material for assessment

Choose a service, describe the case, pay securely, then upload your evidence through a private link. No account required.

This service provides an independent technical assessment of the submitted material. It does not guarantee that manipulation can always be conclusively established, and it does not replace legal advice, law-enforcement investigation or a court-appointed expert opinion.
