The "2D-Doc" solution helps to combat fraud and secure the data exchanged between users and the government.

In collaboration with private and public bodies, the ANTS, commissioned by the Ministry of the Interior, is implementing the "2D-Doc" solution to combat fraud and secure the data exchanged between users and the government.

What is 2D-DOC used for?

The objectives of this solution are:

• to combat document fraud
• to develop e-government
• to simplify administrative procedures
• to secure online services

 

What documents are affected?

This solution makes it possible to secure all types of documents, both paper and digital.

The particular documents are forms of proof (water, telephone and electricity bills, insurance and rent receipts, bank details, income, etc.) used by private individuals and/or professionals in their dealings with companies, government departments, or social services.

 

What are the features of 2D-Doc?

The 2D-Doc two-dimensional barcode standard consists of inserting a 2D barcode into a document, containing:

• key information about the document (type of document, first and last name of the issuer, their title, address, invoice number)
• the date of issue of the document or 2D barcode, and this information is secured by an electronic signature of the hash of this data, which guarantees the identification of the issuing organisation and the integrity of the document.

The 2D barcode is electronically signed by the private key corresponding to a public key placed in a server certificate ("cachet serveur"). This asymmetric encryption means that the signature can be checked by all parties who have the issuing signatory's public key.

This standard is a visible signature that can only be verified by a machine (such as a scanner or barcode reader). If the signature of this data is correct, this indicates that this data and only this data is correct.

 

What is the role of the ANTS?
