Detecting forged signatures
automatically

AI that checks every signature on parcel deliveries instead of just samples. Developed together with research partners from Linz.

The problem

In parcel delivery, every minute counts. Under time pressure, couriers often sign themselves instead of getting the recipient's signature, and simply leave the parcel at the door.

The system then shows a valid signature. Nobody notices until someone complains. Manual checks only cover a sample, and they take a lot of time.

  • Parcels get lost, and investigations and replacements cost money
  • Forged signatures are forgery of documents
  • Parcels left in the open can be a data protection issue
In practice

Not an isolated case, but a pattern

How big is the problem really? In a pilot analysis we evaluated almost 100,000 signatures from three depots. The result: forgeries are not the slip of a few individuals, they show up on almost every route.

Almost a third of couriers forge more than 90% of signatures.

What the AI detects

Three typical patterns

This is what a single route looks like after Signature CHECK has checked it. Each box is a signature that was flagged as forged.

Signatures on one route detected as imitations

Imitation: Different names every time, but clearly the same hand. 58 forgeries on one route.

Signatures on one route detected as initials

Initials: A quick scribble instead of a real signature. 75 times on one route.

False safe drops signed with initials

False safe drop: Parcel left “at the door” and signed off with initials.

How it works

From spot checks to checking every route

1

Capture

Every signature on a route is imported and analysed automatically.

2

Detect

Two specialised AI models find imitations, initials and recurring patterns.

3

Notify

Suspicious routes and couriers trigger a warning in the dashboard.

4

Act

Problems become visible before complaints come in. Important senders can also be monitored closely.

The platform

All routes at a glance

The dashboard shows how the forgery rate develops, which routes stand out and which couriers are involved. One click on a route shows every single signature, sorted into valid and forged.

Signature CHECK runs on your own servers or in a private cloud. Results can be exported, for example to Power BI or QlikSense.
