1. Introduction?of Biometric Fingerprint
(1) Concept
Biometric technology relies on unique physical or behavioral traits that are distinct to each person and cannot be replicated. Among these, fingerprints are one of the most widely used identifiers. The first system to recognize hand images for identification purposes was introduced in India in 1858[1]. Nowadays, with the advancement of technology, fingerprint biometrics has become a part of everyday life.
Fingerprints are unique patterns of arches, loops, and whorls (Fig. 1. Fingerprint Patterns), and nearly no one has the same fingerprint templates as others[2].
So uniqueness is the most important features of fingerprint templates because each person's fingerprint templates are as unique as the fingerprint itself. It is worth noting that when storing a fingerprint template, a numeric template is created based on the extracted features. This template is a mathematical representation of the fingerprint as a unique identifier for the individual[3].?
Fingerprint authentication is a type of biometric identification technology that verifies the identity of an individual based on one or more of their fingerprints[4]. When an individual attempts to use their fingerprint for authentication, their live fingerprint is captured to create a new template. This new template is then compared to the template stored in the database. If the live fingerprint matches the stored template, access is granted and authentication is successful. If it does not match, access is denied.
(2) The applications?of fingerprint scanning
The enduring effectiveness of fingerprint biometrics, coupled with its ease of use, cost efficiency, and high security, makes it a critical tool for authentication and identity management today.
Over the years, fingerprint biometrics are widely adopted across multiple industries due to their reliability and effectiveness in identity registration and authentication. From government programs to commercial applications, this technology plays a critical role in ensuring secure access and identification.
It can be used in different areas:
National ID Programs
In national identity systems, fingerprint biometrics are used to securely store and verify individual identities. Fingerprint data can be encrypted and stored within a card’s chip or a centralized database. During identity verification, the person’s live fingerprint is matched against the stored template, ensuring accurate identification.
Law Enforcement & Public Security
Fingerprint biometrics are essential in criminal identification and suspect tracking. Systems like the AFIS (Automated Fingerprint Identification System) store and compare fingerprint data to match suspects to known profiles in databases, streamlining the process of solving crimes.
Commercial Applications
In banking and retail, fingerprint biometrics add an extra layer of security. Banks and financial institutions use fingerprint scanners for secure transactions, while retail businesses may incorporate fingerprint authentication in credit card readers or payment terminals.

2. Traditional Optical Fingerprint Scanner?Technology
Fingerprint scanners are essential components in biometric authentication systems, capturing and processing fingerprint data for secure identification.
(1) Concept
Optical fingerprint scanners are the earliest fingerprint detection technology and remain widely used due to their simplicity, robustness, and accuracy[5]. These scanners use planar light and an image capture device to photograph the fingerprint, converting the image into a digital format. When a finger is placed on the scanner surface, a planar light source illuminates the surface, and the scanner uses a Charge-Coupled Device (CCD) or Complementary Metal Oxide Semiconductor (CMOS) camera to photograph the ridges and valleys of the fingerprint (Fig. 2. How Optical Fingerprint Scanner Works). The image is then transformed into digital data that can be used for identification[6].
(2) Pros and cons of Optical Fingerprint Scanner
Like any technology, optical fingerprint scanners have both strengths and weaknesses. Here’s a breakdown:

Cons
Optical scanners are vulnerable to spoofing attacks, where fake fingerprints or impressions can trick the system.
Medium to high maintenance costs are required to maintain performance as dust, oil or moisture can degrade scanning accuracy.
Scan quality is highly susceptible to sunlight interference in outdoor applications.
(3) Conclusion
Optical fingerprint scanners are popular for applications ranging from home security systems to government identification programs. However, their vulnerability to spoofing remains a critical limitation, especially when compared to more advanced biometric sensors.
3. Active Thermal Fingerprint Sensor Technology
(1) Concept
Thermal fingerprint scanners offer a unique approach to biometric security, providing precise and reliable scans. Active thermal fingerprint sensors work by detecting temperature differences between the ridges and valleys of a finger, creating a precise image of the fingerprint. Unlike passive sensors, which rely on natural temperature variations, active sensors use an internal heating element to measure heat differences more accurately. These sensors are embedded with heat response signal that react to the temperature changes, generating an electric charge that is then processed into a digital fingerprint template?(Fig.3. How Active Thermal Fingerprint Sensor Works). By using body heat, active thermal sensors ensure that only live fingers are detected, adding an extra layer of protection against spoofing attempts.
(2) Pros and Cons of Active Thermal Fingerprint Sensor
Like optical fingerprint scanner, active thermal fingerprint sensor also has its pros and cons.
Pros
By detecting live fingers and differentiating between real and fake ones, they reduce the risk of identity fraud.
Since active thermal sensors rely on temperature differences rather than visible light, they perform reliably in outdoor and bright sunlight conditions. Active thermal sensors also work accurately with damp or sweaty fingers, ensuring reliable performance in wet condition

(1) Case Study: Voter Fraud Challenges in Fingerprint Scanners
Traditional fingerprint scanners are increasingly vulnerable to security threats like spoofing, where fake fingers, including silicone prosthetics, can easily trick the system.
A notable example occurred during elections in India, where prosthetic fingers were used to manipulate voting. Voters masked their ink-marked fingers with fake ones to cast multiple votes under false identities. According to an investigation by India Today ?in 2017, several prosthetic suppliers were found selling silicone fingers in bulk to political parties aiming to rig elections[7]. This method involved using fake fingers to bypass biometric verification, compromising the justice of the voting process.
It is clear to?see that only relying on software solutions for detecting live fingers has proven insufficient to ensure robust security. Software systems often fail to distinguish between real and fake fingers, as evidenced in cases of prosthetic-based fraud. This exposes significant vulnerabilities in voting sectors, where ensuring authenticity is critical.
It demonstrates that we need more advanced hardware-based biometric solutions. While software plays a crucial role in detection, hardware enhancements are necessary, too.
