This involves changes made to an existing document. Changes might be simple or more complex. Forgers’ motivations might simply be to age themselves to access services or products unavailable to minors, or, on the other hand, to seem younger to benefit from a protective program for minors, or even to postpone a visa or residence permit’s expiration date.
More significant changes may lead to completely altering the identity on the original document.
Some forgers have even become specialists in document “scrubbing,” whereby they obtain a blank document from a personalized one.
With passports, a classic forgery is page substitution. The personalized page is removed and an interior page of the passport is personalized with fraudulent data. The forger seeks to retain the original look of the booklet and paper, even if the page’s pattern isn’t quite right (as it is an inside page).
The original document may be presented by the forger, or be a document stolen from or sold by its legal bearer. Forgery is behind significant trafficking in stolen or “lost” identity documents.
To detect a forgery, concentrate on errors made when the forger alters the document. This means errors in personalization or inconsistencies between the forged and intact sections.
The IDCHECK.IO service uses a database containing thousands of examples of ID documents issued by every country. As a result, the personalization characteristics are known for each document. After the first, automatic ID step for the document, IDCHECK.IO will verify the personalization characteristics to detect this type of fraud.
