- Abstract: The application of mobile biometrics as a user-friendly authentication method
has increased in the last years. Recent studies have proposed novel behavioral
biometric recognition systems based on Transformers, which currently outperform
the state of the art in several application scenarios. On-line handwritten
signature verification aims to verify the identity of subjects, based on their
biometric signatures acquired using electronic devices such as tablets or
smartphones. This paper investigates the suitability of architectures based on
recent Transformers for on-line signature verification. In particular, four
different configurations are studied, two of them rely on the Vanilla
Transformer encoder, and the two others have been successfully applied to the
tasks of gait and activity recognition. We evaluate the four proposed
configurations according to the experimental protocol proposed in the
SVC-onGoing competition. The results obtained in our experiments are promising,
and promote the use of Transformers for on-line signature verification.

Main tasks of signature verification systems include extracting features from signature images and training a classifier for classification.
The instances of skilled forgeries are often unavailable, when signature verification models are being trained.
This paper proposes a new signature verification method using a variational autoencoder (VAE) to extract features directly from signature images.

Signatures extracted from formal documents may contain different types of occlusions, for example, stamps, company seals, ruling lines, and signature boxes.
In this paper, we address a real-world writer independent offline signature verification problem, in which, a bank's customers' transaction request documents that contain their occluded signatures are compared with their clean reference signatures.
Our proposed method consists of two main components, a stamp cleaning method based on CycleGAN and signature representation based on CNNs.
