The engine behind WonderNet's entire product line is the Penflow client-server application which allows easy and secure signature authentication process based on three main stages:
Enrollment
The whole process is initiated by a user registration using an intuitive graphical user interface. The enrollment wizard requires three initial signatures and another three signatures for training purposes. Using a digital pen and tablet, users naturally sign their personal handwritten signature, exactly the same as using a wet-ink pen and ordinary paper

Signature Profile Creation and Handling
Each signature is analyzed by the Penflow engine, and converted to a template. These templates are then processed to form the user?s signature profile. The profile is a robust structure that contains the knowledge of the signature's dynamics and is not influenced by user?s external factors. The signature profile database can be managed by an authorized system administrator using the Penflow server comprehensive management tool. The administrator can perform series of operations per user profile including: suspend, reset or delete the profile.
Signature Verification
Each time a user uses the application to add his signature; the server compares current signature to the pre-enrolled profile. Upon each authentication the server continues to learn and fine-tunes the user's profile. This enables the system to track gradual shifts in the handwritten signature over time.
