Technology
PerceptNote® consists of a hardware and software tool for predicting public perceptual responses to new or existing banknote designs.

Dynamics of security features

A good prediction has to consider not only static structures but also dynamic effects as colour change and movement in security features.

To quantify the amount and nature of image change in a security feature or OVD (Optical Variable Device) PerceptNote® uses:

+
Image analysis and AI driven information quantification
+
Custom designed image capture device
+
Sophisticated post-capture image integration
+
The dynamic contribution to computations on the
whole banknote perception assessment (the attention map)

The image acquisition device

MADIS (Multi-Angle Dynamic Image Scanner)

+
Captures dynamic visual effects as the viewing angle changes
+
Obtains high quality digital images
+
Prevents any distortions due to perspective and parallax
+
Ensures image acquisition standards
+
Proprietary patented technology

Patented scanning technology for accurate multi-angle image capture and objective quantification of dynamic properties.

Dynamic information

Through sophisticated post-capture image integration PerceptNote® obtains:

The Dynamic Map

 

a representation of the complete dynamic information contained in a security document or banknote that provides

 

+   An overview of the banknote’s OVDs

 

+   The quantification of each security feature strength
to allow direct comparisons

 

+   The dynamic contribution to computations on the
whole banknote perception assessment (the attention map)

 

+   A direct way to measure any impact of wear and soil

Whole banknote perception

 

By means of image analysis and AI driven information quantification PerceptNote® calculates:

The Attention Map

 

a representation of the probability of attention at each location that provides

 

+   Distribution of attention

 

+   Percentage of attention for each element

 

+   Perceptual Effectiveness Index (PEI), a prediction of authentication accuracy
