Tax Stamp

Secure traceability solution for tax collection

Tax stamps are used to collect taxes and other fees and are usually issued by local or national governments. The face value of tax stamps justifies the presence of a security element to prevent counterfeiting.

Prooftag offers a complete solution incorporating unitary authentication and traceability to manage the collection of taxes and the verification of tax stamps.

Stamp Flow

Production of a stamp with secured physical characteristics (Over, Covert, Forensic) and a chaosmetric fingerprint.

Stamps are serialized with a unique reference generated by the central system. The serialized reference is associated to the stamp physical characteristics.

The reference can be materialized as :

  • A chain of characters
  • A 2D Code
  • Visible or non-visible ink
  • A serialized or random reference
  • A standard code or encrypted code

Stamps are applied to the product. Physical stamps are labeled on the product while digital stamps are marked on the product.

Items are associated in boxes/carton/palettes. Each of those group is identified to be traced in the system.

Dedicated application and electronic readers offer a secure way to authenticate stamps and to have access to related data.

Their usage improves the efficiency of investigators that can rapidly have access to information allowing them to take necessary actions.

Data Flow

Users who need secure stamps have access to the system allowing them to place orders. The system will generate stamp’s references  directly allocated to the user identity.

Based on Prooftag online platform, authorities can manage stamp orders, production and delivery to manufacturers on a dedicated web portal.

The system can be configured to :

  • Receive and validate production orders
  • Manage stamps personalization data
  • Record stamp production
  • Manage stamp logistics

A production system is set up on the production line to control the application of the stamps and collect the associated information.
The data is automatically loaded into the state's database system for automatic verification.

Auxiliary information is recorded on the logistics of the marked element.

The centralized platform records all actions related to stamps and secure items as well as authentications performed on the platform.
The system generates anomaly reports and creates alerts on stamps that are misused.

Equipment

Prooftag Readers

Formal authentication is ensured by Prooftag readers. Those readers can be used for online and offline authentication and provide a secured access to the central database system.
Those readers can be used to validate the authenticity of chaosmetric pattern as well as Overt and Covert features.

Security Technologies

Production of secured stamps

Chaosmetric Concept

Conventional security technologies are mass-produced and consequently mass-reproducible. Only technologies that cannot be reproduced, even by their own manufacturer, guarantee efficient protection against counterfeiting. Since 2004, Prooftag has developed its own security solutions based on a chaosmetric concept. Like biometrics, that refers to the identification of humans by their characteristics or traits, chaosmetric relies on the recording of physically unclonable features to create a serialized authentication element.

Chaosmetry theory studies the behavior of dynamic systems that are highly sensitive to initial conditions. Tiny variations in these conditions generate a constellation of unpredictable final bubbles. Small differences in these initial conditions give very divergent results for such dynamic systems, making long-term prediction impossible. Chaotic behavior can be observed in many natural systems. In these systems, human intervention influences the outcome but cannot force a certain result.
