MultiFusion Verify
Image and video authentication software

MultiFusion Verify reads a picture, a video or a sound recording the way an examiner does: its file structure, its compression history, the camera's own noise and the traces an edit leaves. Each check is shown as a map or a measurement to read, never as a verdict.

MultiFusion Verify — Face & Person: the man from the register photo found through the gate recording (demo case) demo case

Capabilities

Everything Verify does

Pictures

The traces a camera and an edit leave.

  • JPEG structure and compression history
  • Copied and pasted regions
  • Camera identification (PRNU)

Video

How the file was made, and what changed.

  • Container and encoder
  • GOP structure and bit rate over time
  • Frame-by-frame comparison

Sound

Whether a recording is continuous.

  • Joins and level changes
  • Mains hum (ENF)
  • Bandwidth and room

Frequently asked questions

Does it need the internet?

No. It runs on the examiner's own computer, offline. Evidence files are opened where they are and never uploaded anywhere.

Does it say whether a file is fake?

No. Verify shows each check as evidence — a map, a table or a measurement — with what it measures and its limits. The examiner decides; the report records the methods used.

Which files does it check?

JPEG and other pictures, MP4 and MOV video, and sound in common formats. A folder of pictures can be checked in one run.

How is it licensed?

Each computer gets a 30-day trial once, then a licence file for that computer, checked offline. A MultiFusion Server can also lend floating seats: the app borrows a seat while it is open and gives it back when it closes.
