Handwritten signatures are biometric traits at the center of debate in the
scientific community. Over the last 40 years, the interest in signature studies
has grown steadily, having as its main reference the application of automatic
signature verification, as previously published reviews in 1989, 2000, and 2008
bear witness. Ever since, and over the last 10 years, the application of
handwritten signature technology has strongly evolved, and much research has
focused on the possibility of applying systems based on handwritten signature
analysis and processing to a multitude of new fields. After several years of
haphazard growth of this research area, it is time to assess its current
developments for their applicability in order to draw a structured way forward.
This perspective reports a systematic review of the last 10 years of the
literature on handwritten signatures with respect to the new scenario, focusing
on the most promising domains of research and trying to elicit possible future
research directions in this subject.

手写签名作为生物特征在科学界引起了争议，过去 40 年来对签名研究的兴趣不断增长，主要参考应用自动签名验证，通过对过去 10 年手写签名技术的系统回顾，重点关注最有前景的研究领域，并试图引出可能的未来研究方向。

A Perspective Analysis of Handwritten Signature Technology

The lack of an accessible and effective system for blind individuals to
create handwritten signatures presents a significant barrier to their
independence and full participation in various aspects of life. This research
introduces the Tactile Signature System, a groundbreaking approach that
empowers individuals with visual impairments to form their unique handwritten
signatures. Key features of the system include: Personalized customization:
Through tactile interaction and voice algorithmic guidance, individuals create
signatures reflecting their preferences and natural writing style. Real-time
feedback: AI-powered voice prompts and analysis ensure accuracy and consistency
in signature formation. Accessibility: Installation in local service centers
provides a secure and supervised environment for signature creation. The
system's impact reaches beyond the individual level: Promotes inclusivity and
independence: Blind individuals can engage in legal and financial transactions
without relying on others. Empowers and fosters equal opportunities:
Participation in education, employment, and civic engagement becomes more
accessible. Aligns with international conventions: Upholds the right of persons
with disabilities to participate fully in society. The Tactile Signature System
represents a significant step towards an inclusive and accessible future for
individuals with visual impairments.
