Abstract: Handwritten signatures are one of the widely used biometric traits for authentication, and are constantly questioned as forgery for this behavioural biometric is very common. Also due to privacy concerns, biometric databases are not easily available for training purposes. Due to this the efficiency of automatic authentication systems is highly compromised. The use of biometric data in forensic investigation also suffers from the problem of inadequate data. One of the solutions to this problem is the use of synthetic datasets in place of real datasets. Such datasets suffer from a high risk of generating unrealistic specimens. Generating high-quality synthetic biometric images is still a challenge. This paper discusses some of the basic requirements for synthetic signature generation and also proposes an algorithm to generate synthetic images for handwritten signatures using sinusoidal transformation.
