Biometric authentication is a very popular and secure authentication nowadays and to determine resemblance, it is the process of comparing data for the characteristics of the person to the biometric template of that person. Biometric authentication is simply the process of verifying your identity using your body’s measurements or other unique features, then logging in to a service, an app, a device, and so on. Biometric Authentication has the main advantage of capturing an item of biometric data from any person. It can be a photo of their face, a record of their voice, or a fingerprint image. This data is then compared with several other people’s biometric data kept in a database. How is biometrics utilized in different sectors? Government sector: Fingerprint recognition is an ideal biometric technology for government projects of both large and small scales. Fingerprint biometrics provides a flexible, scalable, and accurate digital identification solution for different government applications such as border control, national identification cards, voter registration, and passports. Banking sector: By implementing biometrics on fingerprints, banks gain substantial benefits. Banks and other financial institutions need to protect financial data from customers and provide customers with safe and easy transactions. With a fingerprint swipe, customers can easily access services at bank branches, and it also links each transaction to the customer. Only authorized employees can use their fingerprint to access sensitive information, and it also creates a concrete audit trail of each transaction. Workforce management sector: By incorporating fingerprint biometrics in their time and attendance systems, organizations can eliminate employee time theft and reduce payroll inflation. With a fingerprint attendance system, automated recording of the check-in and check-out times for employees is possible. Clock-in at work requires the employee to be present and thus a fingerprint system eliminates the possibility of punching the buddy. Fingerprint time and attendance systems increase employee productivity and promote accountability through the creation of a concrete audit trail of employee transactions. Advantages: Low maintenance Improved customer experience Cannot be forgotten or lost Reduced operational costs High security Flexible design Easy enrollment Enhanced user experience Disadvantages: Environment and usage can affect measurements Systems are not that much accurate Require integration or additional hardware Cannot be reset once compromised
