Fingerprint Recognition Patent: Security in Biometric Device

In a world driven by technology, securing sensitive information while accessing various digital systems has become crucial. Fingerprint recognition, a form of biometric technology, has emerged as a reliable and convenient means of enhancing security. The use of fingerprint recognition has grown significantly in recent years. It is now a common feature in many aspects of our lives, from unlocking our smartphones and accessing secure apps to entering high-security facilities, this technology is everywhere.

Fingerprint security is a way to protect information or access to devices by using our unique fingerprint. It may be understood as a digital lock that opens only when it recognizes our fingerprint. This makes it difficult for unauthorized people to gain access to the personal information contained in our phones or computers because each fingerprint is different.


The Principles of Fingerprint Security

Fingerprint security is based on the following key principles:

Uniqueness of Fingerprints: Fingerprint security relies on the fact that each person has a unique set of ridges, valleys, and minutiae patterns on their fingertips. Even identical twins have different fingerprints, making it a reliable method for individual identification.


Fingerprint Image Capture: Fingerprint recognition systems use various techniques to capture an image of the fingerprint. This can be done through optical methods (such as using a camera or scanner to capture an image of the fingerprint), capacitive methods (measuring the electrical properties of the skin), or ultrasonic methods (using sound waves to create an image of the fingerprint).


Feature Extraction: Once the fingerprint image is captured, the system extracts specific features and details from the image, such as ridge endings, bifurcations, and ridge minutiae. These features are used to create a unique digital representation of the fingerprint.


Template Creation: The extracted features are used to create a fingerprint template, which is a mathematical representation of the unique fingerprint characteristics. This template is stored securely in a database or on a device.


Matching Algorithm: When a user attempts to access a system or device, their fingerprint is captured and processed to create a live fingerprint template. A matching algorithm then compares the live template to the stored templates in the database to determine if there is a match.


Authentication: If the live fingerprint matches a stored template within an acceptable level of tolerance, the user is granted access. If there is no match, access is denied.


Security and Encryption: Fingerprint data and templates are typically stored and transmitted in an encrypted format to protect against unauthorized access or tampering. This ensures the security of biometric information.


False Acceptance and False Rejection Rates: Fingerprint security systems must balance the risk of false acceptance (allowing unauthorized users access) and false rejection (denying access to authorized users). The system’s accuracy is typically measured by these rates.


Sensor Technology: The quality and accuracy of fingerprint recognition depend on the technology and sensors used. Advances in sensor technology have greatly improved the performance of fingerprint recognition systems.


Why innovation in fingerprint technology should be a continuous process

The accuracy of conventional fingerprint devices is not infallible. They tend to struggle when encountering fingers that are excessively dry or greasy, or when the sensor platen is marred by dirt and smudges. In such scenarios, the reliability of fingerprint recognition is seriously compromised. That is why we need continuous research, development, and collaboration which will ensure that fingerprint technology continues to evolve and meet the ever-changing needs of society while maintaining high levels of accuracy and security.

This technology has gained significant attention and development in recent years. In a world where security is paramount, fingerprint recognition patents contribute to creating a safer and more secure digital landscape. This state of constant improvement ensures that security measures remain effective against emerging threats.


Is making the invention of fingerprint recognition alone enough?

Patenting fingerprint recognition technology is important because it not only protects the intellectual property of innovators but also promotes innovation, attracts investment, and ensures the technology’s ongoing development and improvement. This balance between protection and competition ultimately benefits consumers by providing them with secure and advanced fingerprint recognition solutions.


The Evolution and Significance of Fingerprint Recognition Technology: Embracing Neural Network Algorithms

Fingerprint recognition technology has undergone a remarkable evolution over the years. From its initial applications in law enforcement to becoming a ubiquitous feature in modern smartphones, this biometric technology has come a long way. In recent times, the integration of neural network algorithms has revolutionized fingerprint recognition, making it more accurate, secure, and accessible than ever before.

Fingerprint recognition, often referred to as fingerprint biometrics, relies on the unique patterns of ridges and valleys on an individual’s fingertip. The technology behind fingerprint recognition has been widely adopted due to its accuracy and reliability. However, the recent incorporation of neural network algorithms has taken this technology to new heights, making it even more effective.

However, patenting algorithm-based fingerprint recognition technology can be complex and depends on important factors:

Non-Compliance with Section 3(k): In the realm of technology-related patents, software patents not associated with any hardware will not be considered as patents. In India, a software cannot be directly patented unless it is coupled with a novel hardware component that is a unique invention and can be industrially applied. Section 3 of the Act outlines the types of inventions that are ineligible for patent protection, and Section 3(k) explicitly excludes “mathematical or business or a computer program” or “algorithms” from patentability.

Innovative Algorithms: To secure a patent for Fingerprint Recognition, inventors typically need to develop innovative algorithms that enhance the accuracy, speed, or security of finger recognition systems. These algorithms must demonstrate a technical solution to a problem. If the inventor’s software includes a novel and inventive algorithm for processing and recognizing fingerprints, they may be able to patent this algorithm.

A fingerprint recognition patent protects intellectual property related to novel algorithms, hardware integration, data security measures, efficiency improvements, and various applications of fingerprint recognition technology.

TECH5, a company specializing in biometric technology, has received a U.S. patent for its AI-driven fingerprint scanning technology used in its T5-AirSnap Finger solution. The patent, numbered 11721120, is titled “Contactless Fingerprint Capture using artificial intelligence and image processing on integrated camera systems.” The patent details a system that is capable of producing a 3D depth map of a finger, enabling a high resolution of 500 dots per inch (dpi).

The technology described in the patent relies on neural network models, which are trained to detect various characteristics of fingers, such as size, direction, and the visibility of nails in captured images. These models also generate fingerprint templates of a fixed length that can be used for subsequent fingerprint matching. The use of a 3D depth map helps reduce distortion caused by the curvature of a fingerprint, ultimately improving accuracy.

One of the noteworthy aspects of this technology is that it is designed to work on standard smartphones, eliminating the need for specialized hardware for contactless fingerprint capture and scanning.


Fingerprint recognition technology has undeniably played a pivotal role in shaping a safer and more secure digital landscape. As technology continues to evolve, it is essential to strike a balance between security and intellectual protection on this technology. Achieving this balance will help create a digital world where sensitive information is protected, and individuals can have confidence in the security measures that safeguard their digital lives. The impact of fingerprint recognition patents on digital security is significant, and their continued evolution promises a safer future in the digital realm. By balancing the need for security with intellectual protection, they have paved the way for an innovative and secure digital world.
