Document Security

Secure the authenticity and integrity of your documents

The ever-increasing flow of people, products and information require the implementation of secured documents that can be rapidly identified and authenticated.

Prooftag has developed a strong expertise in the protection of sensitive documents. We offer security solutions based on a combination of physically unclonable chaosmetric features and IT services to fight document counterfeiting and forgery. Thanks to our solutions we can ensure each document:

Unicity of the document

The Authenticity of the document

The content Integrity

Traceability throughout their life cycle

Document security solution for governments
Government application - securing documents to protect against counterfeiting


Unicity, Authenticity, Integrity

Prooftag offers a document security concept around CertiDOCS®. This software suite combined with Prooftag range of security technologies offers a high-security solution to combat fraud, forgery, and counterfeiting of documents.
This document certification solution is applicable to all sorts of documents, regardless of their nature, their quantity or the production means. The solution has been designed to work on new documents as well as on existing documents.
The concept is based on the implementation of a Prooftag chaosmetric feature associated with the content of the document in a secure database.
CertiDOCS® allows the issuance of documents in a centralized and decentralized way to ensure their authenticity, integrity and confidentiality.


Secured Document

Document Protection

The document is produced on a blank support on which is applied a chaosmetric feature or from a support integrating this feature beforehand.

The physical presence of the chaosmetric feature, in relation to its registration in an information system, ascertains and proves the origin and authenticity of the document.

Document Certification

Association of the document content in a digital format with the chaosmetric fingerprint signature to certify the data: the recording in an information system of the content of the document in association with the chaosmetric fingerprint certifies the integrity of the document data.
This certification makes it possible to fight against the falsification of data.

In order to certify data integrity, it is possible to store only the digital signature (SHA 512) of the digital document in association with the Security Seal in a remote database.
This function guarantees the confidentiality of the data…


Authentication of a document

Visual Authentication

Visual authentication of the chaosmetric fingerprint with its registration in the information system.

Validation of the content of the physical document with its registration in the information system.

Electronic Authentication

Electronic authentication of the chaosmetric fingerprint with an eDMR® reader connected to CertiDOCS® Control.

Validation of the document content directly on CertiDOCS control.

Security Technologies

Solutions for document security

Our technologies

Conventional security technologies are mass-produced and therefore mass-reproducible. Only technologies that cannot be reproduced by their own manufacturers can offer the assurance of effective protection against counterfeiting.

Since 2004, Prooftag has been developing its own security solutions based on the chaosmetry concept. Like biometrics  that identifies human beings by their physical characteristics, chaosmetry relies on recording non-cloneable physical elements to create a serialized authentication feature.
