The engine behind Signishell's entire product line is the Signishell
client-server application which allows easy and secure electronic
signature authentication process based on three main stages:
Electronic Signature Enrollment
Electronic signature enrollment 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 signature pad (digital pen and tablet),
users naturally sign their personal handwritten signature, exactly
the same as using a wet-ink pen and ordinary paper.

Electronic Signature Profile Creation and Handling
Each
signature written on the signature pad, is analyzed by
the Signishell 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 dynamics and is not influenced by the user's external
factors. The signature profile database can be managed by an
authorized system administrator using the Signishell server
comprehensive management tool. The administrator can perform
series of operations per user profile including: suspend, reset
or delete the profile.
Electronic Signature Verification
Each time a user uses the application to add his signature; the server compares
the current electronic signature, written on the signature
pad, 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. |
