### What is Biometric Authentication? {#what-is-biometric-authentication}

Biometric authentication is a method of identity verification that uses unique physical characteristics of individuals known as biometric data, such as fingerprints, facial recognition, voice recognition, etc., to verify the identity of an individual. For banks, fintech, and healthcare businesses, this technology offers a more secure and convenient way to authenticate customers and protect against fraud. Banks and fintech companies can ensure that their sensitive information and funds are safe and also their customer’s accounts are protected against cyber attacks.

A healthcare organization can ensure that the privacy of their patients is safe and also ensure that a fraudster doesn’t break into confidential patient information. Most banking apps and fintech apps require customers to log in through biometric authentication like fingerprint authentication, facial recognition, etc. It is also popularly used with Multi-factor Authentication, where biometric verification can be one of the 2FA factors for authentication.

### What is Biometric Data? {#what-is-biometric-data}

Biometric data refers to any information related to a person’s physical, behavioral, and biological characteristics that can be used for identification purposes. This can include measurements or features such as fingerprints, facial recognition, iris scans, voiceprints, and even behavioral biometrics like gait or body posture.

Biometric data is often used in security systems, access control, or identity verification. It is considered more secure than traditional methods such as passwords or PINs, as it is unique to each individual and cannot be easily replicated or stolen.

However, the use of biometric data raises concerns about privacy and security, as it can be vulnerable to hacking, data breaches, and unauthorized access. Therefore, it is important to have proper safeguards and regulations in place to protect biometric data.

### What is a Biometric Authentication Device? {#what-is-biometric-authentication-device}

A biometric authentication device is an instrument that records or aids in the recording of biometric data and also facilitates biometric authentication based on the recorded data. This device does both the job of recording and also using that data for biometric verification of the user identity. Biometric authentication devices are becoming increasingly popular in many industries as they offer a more secure and convenient way to authenticate a user’s identity compared to traditional methods like passwords or PINs. Most of these biometric authentication devices are lightweight and easy to use. Without these devices biometric authentication will not be possible, hence, these devices are the essential components that make the magic of biometric authentication possible.

Some examples of biometric authentication devices include:

1. Fingerprint scanners: These devices use a person’s unique fingerprint to authenticate their identity. The user places their finger on the scanner and the device compares the fingerprint to a stored database of authorized fingerprints.
2. Facial recognition systems: These devices use advanced algorithms to recognize a person’s face and compare it to a stored database of authorized faces.
3. Iris scanners: These devices use the unique pattern of a person’s iris to authenticate their identity.
4. Voice recognition systems: These devices analyze the unique characteristics of a person’s voice to authenticate their identity.

Apart from these examples, there are many different types of biometric authentication devices that can collect various types of physical and behavioral biometrics. This provides a more secure and convenient way to authenticate a person’s identity and is increasingly being used in various industries, including banking, healthcare, and government.

### How does Biometric Authentication Work? {#how-does-biometric-authentication-works}

Biometric authentication is a process that uses biometric data and a biometric authentication device to verify the identity of an individual. The individual’s biometric data is collected through a biometric verification or authentication device. This can include facial recognition, fingerprint scans, iris scans, voice prints, or behavioral biometrics such as gait analysis. Then the collected biometric data is converted to a digital format that can be digitally stored in a database or directory and compared against future authentication attempts.

The digital biometric data needs to be stored in a secure database that can only be accessed by authorized personnel. Otherwise, biometric data is very sensitive and prone to getting hacked or stolen by cybercriminals and fraudsters. When the individual attempts to authenticate their identity, their biometric data is collected again and compared to the stored data in the secure database. If there is a match, the individual is granted access.

### Popular Use Cases of Biometric Authentication

#### Case 1: Fingerprint Authentication in Finance Apps

Fingerprint authentication has become increasingly popular in finance apps as a means of improving security and user experience. Most people using these finance apps are busy professionals who frequently use their banking apps to check their account balances, pay bills, and transfer funds. The users of these finance apps would want their financial information to be secure, but at the same time, it is inconvenient for them to enter a password every time they access the app. Also, passwords can be weak and easily stolen.

To solve this issue, most finance apps have implemented passwordless fingerprint authentication as a security feature in their app. Now, instead of entering a password every time, they can simply use the app by using their finger on the fingerprint sensor of their smartphone or tablet. The app uses the unique pattern of the user’s fingerprint to authenticate the user’s identity and grant access to their respective accounts.

#### Case 2: Behavioral Biometrics in Healthcare Sector

Behavioral biometrics can also be useful in the healthcare sector to help prevent fraud, protect patient data, and ensure compliance with regulations. Healthcare providers like doctors, nurses, etc., are frequently required to access electronic medical records (EMRs) to review patient data, update patient charts, and prescribe medications. Healthcare institutions are always under constant threat of security breaches and loss of patient data or EMRs.

To solve this issue, healthcare organizations can implement behavioral biometrics to verify the identity of authorized personnel who can access EMRs. The behavioral biometrics system analyzes the authorized personnel’s usual patterns of behavior, such as the time of day, the location, the speed of typing, the navigation, and the amount of patient data viewed, to create a baseline of what is normal. If there is a deviation from the normal baseline, the system will flag the activity as suspicious and require additional authentication methods like multi-factor authentication. Behavioral biometrics can help healthcare organizations comply with regulatory requirements, such as HIPAA, by providing an additional layer of security to protect patient data.

### In Summary {#summary}
