An identity document is made up of a blank document that is personalised with its holder’s data. When the job of personalisation is decentralized (to local authorities), blank identity documents are sent to these points. Forgers take advantage of this transit to steal some of the blanks, and then personalise them.
Today, identity documents are mostly personalised in a secure central location to avoid this kind of fraud, although exceptions exist: visas. for example, are necessarily personalised in consulates and embassies. Stolen blank fraud is a significant concern for this kind of document.
To detect stolen blank fraud, we concentrate on errors made when the counterfeiter personalises the document. 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.
