Forensic document examiners perform similar duties to those of fingerprint examiners, where they compare the visual features of handwriting associated with a known writer to those of an unknown writer, and then makes a decision about whether the two samples belong to the same source.

What did we collect?

We used a short ‘capture-all’ paragraph (‘The London Letter’) to collect a sample of a participant’s handwriting. This paragraph contains every letter of the alphabet, in upper and lower case, as well as every digit from 0-9.
