Today, the fingerprint-capturing process starts with placing your finger onto a fingerprint scanner or fingerprint reader that scans unique details like ridges, furrows, and other fingerprint characteristics. This data is then stored as a biometric template or profile which can be used for precisely pinpointing an individual’s identity. With such high levels of accuracy, fingerprints and fingerprint recognition have proven invaluable for a wide range of applications.
Fingerprints are captured and recorded using a variety of different methods, depending on the application and use case. Some of the most common methods include:
1) Live scan:
A live scan device, also known as a biometric fingerprint scanner, is typically used for law enforcement or forensic applications where high-quality fingerprints are required. To capture the fingerprint, a user places their finger on a glass plate and the device digitally scans and photographs the fingerprint. This method can produce highly detailed, high-resolution fingerprints that are often used in fingerprint analysis.
The FBI has set up a fingerprint scanner certification program for live scan devices. This program makes sure that the devices meet certain image quality requirements. These standards were originally made for law enforcement, but they have now become an industry standard.
2) Paper and ink:
If you’re looking for a classic way to record prints, utilizing ink and paper is the traditional option. This process consists of rolling an inked finger on specific paper before scanning or taking a photo of the image digitally.
Law enforcement agencies have depended upon this method from centuries ago up until the modern day; it’s even been used when applying for visas and passports! The fingerprint cards used for this method developed during the 1900s are still practiced today, but they’ve been ameliorated to match rising quality parameters.
How Are Fingerprints Used?
The uniqueness of each person’s fingerprints has led to the creation and implementation of fingerprint biometrics for a variety of purposes. The history of fingerprint identification goes back to the 19th century when police officers and fingerprint examiners would compare suspected criminals’ fingerprint records with those of known offenders. At that time, fingerprints were mainly used as a way to identify people who had been arrested or detained.
As fingerprint identification technology evolved, its utility extended far beyond the realms of criminal investigation and became increasingly adopted in other sectors. With improvements to standard practices and procedures, usage rapidly expanded exponentially with time.
Today, fingerprints can be used for more than just solving crimes; they are also commonly found in everyday life. Many mobile devices now come with fingerprint sensors installed, allowing users to unlock their phones quickly and securely without having to enter a passcode or password every time. Similarly, many banks now use biometric scanning technology such as fingerprint scanners for authentication purposes when customers access their accounts online or in person at the bank branch. Below we outline some of the main uses for fingerprints in different spheres:
1) Law enforcement using fingerprints:
Since the days of early police work, fingerprinting has been a mainstay of identifying criminals and solving crimes. Law enforcement officers have been leveraging fingerprint technology for numerous years to apprehend suspects and reduce criminal activity. Some agencies are now utilizing automated tools that can quickly analyze crime scene fingerprints, allowing them to make more precise identifications. The FBI is one of the many law enforcement entities that employ IAFIS (Integrated Automated Fingerprint Identification System), now known as Next Generation Identification (NGI), which is one of the most well-known national fingerprint databases and has over 60 million fingerprints and other identifying information for criminals.
Additionally, the method of latent fingerprint identification is also used by law enforcement to reveal latent fingerprints, process them, and match them to the known prints of a suspect.
Latent fingerprints are those that can’t be seen without chemical or fingerprint powder (such as black granular, magnetic, or silver nitrate) enhancement and may be found on surfaces such as glass, wood, plastic, or metal. After they have been isolated and visualized, they can then be compared with known criminals’ databases to achieve a match and identify those responsible for the crime.
2) Banking and finance using fingerprints:
Fingerprint technology has found a place in the world of finance, where fingerprints are often used to identify customers. By employing biometric authentication for KYC verification when customers access their bank accounts both online and at branches, financial institutions can make sure that fraud and money laundering do not occur. Fingerprint recognition have revolutionized additional security measures, from mobile applications to account openings and money transfers.
This milestone for the technology can provide much-needed peace of mind to customers, help make transactions safer, and improve financial inclusion.
3) Healthcare using fingerprints:
Fingerprints are often used in the healthcare industry to help prevent medical identity theft and other forms of fraud that result from incorrect patient identification. The use of automated fingerprint detection systems, like those found in hospitals and clinics, makes it simple for doctors and nurses to quickly identify patients.
Other healthcare applications include allowing access to medical records, prescription drugs, and medical devices.
4) Access control using fingerprints:
Fingerprint authentication is a popular way to protect residential and commercial buildings, airports, train stations, school campuses, and other public places.
Biometric security through fingerprints provides enhanced physical security while reducing the risk of unauthorized personnel misuse.
5) Fingerprints in other fields:
In addition to these main applications, fingerprint analysis and identification technologies are also used for other purposes such as retail POS, biometric passports for immigration administration, automated biometric identification system for governments, voter registration, public welfare, student attendance tracking in educational institutions, border control, and many more.
Overall, it is clear that fingerprint identification technology has become a valuable asset to society, whether in law enforcement, banking, finance, healthcare, or other areas. By providing a simple, accurate way to identify individuals in any situation while also protecting against fraud, this technology is sure to continue revolutionizing the world for years to come.
