Know exactly
who signed.
A looping demo of the identity check, one subject at a time inside a single frame. First a government ID appears and a beam scans across it, revealing the printed photo, the data lines and the machine-readable strip. The ID leaves and a full face arrives; the same beam scans it while eight landmark points lock onto the brows, eyes, nose, mouth and chin. The face then drops to its right half and the left half of the ID takes the space beside it, the two meeting on a seam. A sweep of light passes over both halves together and the result reads: identity verified.
New in DottSign: identity verification
Ask any signer to prove who they are before their signature is accepted: a government ID, a liveness check and a face match. We keep the result, never the document data.
