Handwriting analysis is the oldest biometric authentication method. Our
signature is accepted everywhere and not making conflicts with law or traditional
habits. Everyone knows and using his signature in the every days, so there is no need to
learn something new for this kind of authentication.
Any document can be validated by handwritten signature, which is meaning
huge responsibility. Still today no one examines the origin of our signatures, except
some suspicious cases. The purpose of my thesis is to develop an application, which
facilitates the spreading of offline signature verification. Nowadays everyone has
mobile phone and holding in his pocket. Let us utilize the great opportunities, as a
mobile phone’s technology level is sufficient for taking good quality picture of the
handwritten signature. And further more has the software environment to send a remote
server using high level of encryption. On the serves side, comparing with previously
collected samples, we can send back the results guaranteeing the originality of our
signatures. Using this kind of application can fight off against the more and more
efficient forgeries.
I see boundless number of opportunities in this kind of static signature
verification supporting application. Especially knowing, that millions of documents are
made by each day with handwritten signature.
