FiberTag ® is a chaosmetric security technology that uses a random distribution of colored fibers
combined with a 2D serialized code to create a unique fingerprint for each label

Chaosmetry relies on the registration of physical elements that cannot be cloned to create unique fingerprint.

During the production of FiberTag®, infinitesimal variations in initial conditions during the incorporation of security fibers into the paper pulp result in a final dispersion of the fibers that is totally unpredictable.

The characterization of a FiberTag ® by its measurement gives a unique result that allows identification of each fiber relative to the others.

Each FiberTag® is unique and impossible to duplicate even by its original manufacturer.

Physical Characteristics


FiberTag ® is produced with a proprietary uncoated paper available in different weights.

The paper used has been developed specifically for the application.

This paper integrates visible and invisible security fibers perfectly characterized.


The security fibres are included in the pulp during production.

The depth of the fibres in the thickness of the paper makes them appear more or less distinct.


Seals and Labels

Seals and Labels are printed on Fibertracker security paper with digital presses.

They can have any shape and design and can incorporate a tamper evident design to reduce the risk of removal and repositioning.


FiberTag® cards are cold laminated cards that can be integrated in a laser or inkjet personalization process on conventional office equipment.


Fibertracker® can be used to produce high security

documents. Each sheet has an embedded non removable FiberTag® to certify the authenticity of each document. 

Security Levels


FiberTag® has two-color security fibers embedded in the thickness of the paper.

Required equipment: None
Users: General public


FiberTag® incorporate non visible security fibers that glow under UV light.

Required equipment: UV lamp
Users: Professionals


The fiber dispersion of each FiberTag® is recorded in Prooftag Cerv to become a unique non forgeable fingerprint.

Required equipment: Smartphone, internet access
Users: General public
