The need to keep any important or personal data and documents safe is escalating due to the progress of technology today. Using biometric authentication is considered as one of the most secure and valid authentications due to its uniqueness.
But, what is biometric authentication? Many people or organizations use this type of authentication nowadays. However, not everybody understands what biometric authentication means for security in the effort to keep your data safe.
What is Biometric Authentication?
Every person has their uniqueness biologically, such as iris or retina patterns, facial recognition, fingerprints, palm prints, or voice prints. All this uniqueness is used as biometric authentication as a way of identity verification.
This authentication is used to grant access to devices, systems, and services, and is often considered more secure than traditional authentication methods such as passwords, which can be compromised through brute-force attacks, phishing, or other types of online fraud.
When a user attempts to authenticate, the system compares the biometric data provided with the stored data to verify the person's identity. This process is often completed in a matter of seconds, making biometric authentication a fast and convenient way to verify identity.
Benefits of Biometric Authentication
Overall, biometric authentication provides a range of benefits over traditional authentication methods and is increasingly being used in a variety of settings, from mobile devices to airport security checkpoints.
After reading the biometric authentication definition above, here are several benefits of biometric authentication over traditional authentication methods, including:
1. Improved Security
Biometric authentication is considered more secure than traditional authentication methods, as it uses a person's unique physical characteristics to verify their identity. This makes it much more difficult for someone to impersonate or fake someone else's identity.
That means it can help reduce the risk of fraud and identity theft, as it is much more difficult for attackers to impersonate someone's physical characteristics than it is to steal or guess a password.
Biometric authentication can also help improve the user experience by reducing the friction and frustration associated with traditional authentication methods. This can help increase user satisfaction and reduce support requests related to forgotten passwords or other authentication issues.
2. Convenience and Ease of Use
Biometric authentication is easy to use and does not require users to remember and enter complex passwords or other authentication codes. This makes it more convenient for users, particularly in situations where they need to access devices or systems quickly.
This system also increased efficiency because it is fast and efficient, enabling quick access to devices, systems, and services. This can help save time and increase productivity, particularly in large organizations or situations where multiple users need to authenticate quickly.
The cost-effectiveness of using biometric authentication will depend on several factors, including the type of biometric technology being used, the size and complexity of the system being secured, and the specific use case for this authentication.
In general, a biometric authentication system can be a cost-effective solution for security and identity verification in a variety of settings. It can help reduce costs associated with password resets, account lockouts, and other common issues associated with traditional authentication methods.
However, there may be some upfront costs associated with implementing biometric authentication, including the cost of biometric scanners or other hardware, software development, and training for users.
Additionally, there may be ongoing costs associated with maintaining and updating biometric systems, including regular maintenance and software updates.
Common Applications of Biometric Authentication
Here are some of the applications that commonly use biometric authentication process that people can easily find today:
1. Smartphone Unlocking
This is the process of gaining access to a mobile device, typically a smartphone, using an authentication method such as a passcode, fingerprint, facial recognition, or other biometric authentication method.
Smartphone unlocking is important for securing the personal data stored on the device and protecting against unauthorized access. The method of access that are most commonly used are:
- Passcode: This is a combination of numbers or letters that must be entered to unlock the device. Passcodes are typically used on all types of smartphones and are considered a basic form of security.
- Fingerprint: This type of authentication allows users to unlock their smartphones using their unique fingerprints. This method is considered more secure than passcodes and is available on many modern smartphones.
- Facial Recognition: This recognition technology uses the camera on the smartphone to scan the user's face and unlock the device. This method is becoming increasingly popular on many smartphones.
- Other Methods: Some smartphones also support other biometric authentication methods. For example, iris scanning, voice recognition, or even palm print recognition.
Smartphone unlocking is essential to maintain the security and privacy of the device's data. However, there are some potential security concerns associated with certain types of smartphone unlocking methods, particularly facial recognition.
Facial recognition can be vulnerable to spoofing attacks and may not be as secure as other methods, such as fingerprints. Smartphone users need to choose a suitable authentication method that is both convenient and secure and follow best practices for securing their devices, such as regularly updating software and avoiding public Wi-Fi networks.
2. Online Banking
Biometric authentication is increasingly being used to secure financial transactions, such as withdrawing cash from an ATM or making purchases with a credit card. But biometric authentication can be used to verify the identity of online users, reducing the risk of fraud and cyber-attacks.
The system usually asks the person to do certain activities in front of the smartphone or laptop or any device’s camera. Such as blinking, smiling, turning your head to left or right, or nodding. The system will compare that activity with the data stored in the server before permitting to continue any transactions.
3. Healthcare Records
Biometric authentication is used in healthcare to ensure that only authorized personnel can access patient records and medical information. The most commonly used is fingerprint or palm authentication.
The more complex biometric authentication is used to restrict access to buildings, rooms, and other important physical locations, such as medicine storage or laboratory. Examples include fingerprint scanners, facial recognition systems, and iris scanners.
4. Travel and Immigration
Biometric authentication is used at borders and airports to verify the identity of travelers and ensure that they are authorized to enter a country. Usually connected to law enforcement agencies to identify suspects and track criminal activity. Commonly used is fingerprint authentication, but some countries also have iris scanners.
Using biometric authentication to make your data safe will be the best security one can get. Because of its uniqueness, no unauthorized people can get to the protected data other than the person to which it belongs. That is the best way to keep your data safe and secure.
One alternative security method to biometric authentication is the use of one-time passwords (OTPs). OTPs are temporary, single-use passwords that provide an additional layer of security during the authentication process.
