Electronic
Signature Recognition
No
sooner do we learn how to write, do we learn how to sign
our names. It is second nature to us and has been strongly
ingrained in our working processes. Biometric Signature
Authentication (BSA) authenticates the identity of
individuals by measuring their hand-written signatures.
The electronic signature is treated as a series of
movements that contain unique biometric data, such as
personal rhythm, acceleration and pressure flow.
A
person's two signatures can never be the same. Because Biometric
Signature Authentication can track each person's natural
signature fluctuations over time, it can easily
distinguish between an authentic and a forgery. Unlike
electronic signature captures that are often used today,
Biometric Authentication Signature does not treat the
signature as a graphic image. In graphic images such as
the scanned-in signatures we often attach to our
documents, the dynamics within each individual's signature
can not be detected and hence the signatures can be
copied. Instead, Biometric Signature Authentication
measures how the signature is signed.
Biometrics
Signature Authentication (BSA) also known as Dynamic
Signature Verification (DSV) is different from electronic
signature capture in which the signature is merely stored
in electronic form and no biometric comparisons are
performed. In a DSV system the user signs his signature on
a digitised graphics tablet or PDA. Signature dynamics,
such as speed, relative speed, stroke order, stroke count
and pressure are analysed.
The
system compares not merely what the signature looks like,
but also how the signature is signed. A number of
hospitals, pharmacies and insurance firms use DSV to
authenticate electronic documents, and because DSV closely
resembles the traditional signature process it has minimal
public acceptance issues.
