Identity document verification consists of analyzing a document to confirm its authenticity and detect potential falsifications. It applies in particular to passports, identity cards, driving licenses, and residence permits.

These documents are used to confirm a person’s identity in many contexts, including KYC procedures, administrative services, financial services, and digital platforms. Verification helps prevent fraud and ensures the reliability of information.

With the digitization of exchanges, identity documents are often transmitted as images or digital files. This evolution facilitates exchanges but also increases the risk of falsification. In-depth analysis is required to detect modifications and confirm the authenticity of the document.

Which identity documents can be verified

Verification can be applied to different types of official identity documents. Passports are among the most commonly used documents and include several security features that help confirm their authenticity.

National identity cards also contain security features and an MRZ that allows verification of the integrity of the information. Driving licenses and residence permits can also be analyzed to detect potential inconsistencies or falsifications.

Each type of document has specific characteristics that can be analyzed to confirm its validity.

How to verify an identity document

Verification relies on analyzing visible information and security features. The consistency of data, including dates, document numbers, and personal information, must be verified.

The MRZ (Machine Readable Zone) allows validation of the information using check digits defined by the ICAO 9303 standard. This verification helps detect inconsistencies and falsifications.

Analysis of security features such as holograms, document structure, and visual characteristics also helps confirm authenticity.

When the document is transmitted in digital form, metadata and file structure analysis can detect potential modifications.
