To detect a forgery, we concentrate on errors made when the forger alters the document. This means errors in personalisation or inconsistencies between the forged and intact sections.
The IDCheck.io service uses a database containing thousands of examples of identity documents issued by every country. As a result, the personalisation characteristics are known for each document. After the first automatic document identification step, IDCheck.io verifies the personalisation characteristics to detect this type of fraud.
