Traditional Security VS Biometric Security

Before discussing traditional security vs biometric security we will see what authentication is? Authentication is the method that decides whether someone or something is who or what it claims to be. Validation of a customers’ credential is termed authentication. And it helps customers and businesses as well. When a customer wants to use a specific service he/she has to go through specific produces. These procedures actually involve getting verified by the vendor or the service provider.

Methods of verification:

The validation or verification process may include a traditional approach or a modern one. Whereas, the basic steps include providing all the necessary data. Moreover, that data comprises customers’ ID cards, addresses, and other basic identity verification documents. As a result, all this helps businesses and financial institutions to be more secure. Therefore, offering a trusted environment where customers can make the best use of their software applications.
Proper user verification is a critical component of access control and a key component of any system’s security.

Reasons for Need for a security system:

Identity theft and other personal-related data breaches are major causes of all the security concerns in different institutions like banks and FinTech companies. Therefore, security issues are a major concern of various organizations. Moreover, these Traditional security threats and issues are of significant importance in any institution. So companies devise ways to make systems secure.

Methods of security:

There are two security methods to secure the systems in organizations.
1: Traditional security
2: Biometric security

1: Traditional Security system:

Since the dawn of electronic computing, passwords, PINs, hidden codes, and other similar methods of securing digital data have been commonly used.

Examples of traditional authentication methods.

User authentication via providing the credentials, log in via SMS or email-based token are some of the trivial examples of traditional authentication methods.  Traditional access controls, as the name suggests, have been in use for quite some time and are still commonly used today. They’re not the same as biometric access control systems, but they’re the ones most of us are familiar with. Train stations have turnstiles, while airports have ticket controllers. We use a key to a doorknob or an access card in hotels, and both are very safe. Well, unless someone makes a copy of your door key or access card.

Types of traditional security:

Traditionally, user identification/authentication is based on:

  • Something the user knows (typically a PIN, password, or passphrase)
  • A user-owned item (e.g., key, token, magnetic or smart card, badge, passport).
    The traditional security system includes:
  • Passwords
  • Id cards
  • Knowledge-based authentication
  • Verification based on tokens
  • Verification outside of the band
  • Phrases/hints for verification


PINs and passwords are now commonplace. Whether on your home PC, computer, online account, or smartphone apps, and they have been for a long time. PINs provide physical access control in many cases (for instance, door locks with numeric codes).
Passwords are fantastic because they are a simple and straightforward way to enforce data protection. Password protection does not require any extra hardware and can be implemented entirely in code.
Developers pushed password policies to eliminate the danger when people practiced using basic passwords for the sake of remembering them. It made passwords difficult to crack. Moreover, they are difficult to remember, adding more friction to an already difficult authentication process. 

Information based verification:

KBA uses a shared secret. That is usually a requirement at the time of account generation. And then presented on demand in future challenge/response authentication sessions.

Verification Using Tokens

Hacking into an account that generates a token on new login attempts is much more difficult.  Because to hack that, the hacker requires the account credentials including the tangible hardware device too. Which is much more difficult to obtain for a hacker. Examples of tokens are dongle, card, key fob, or RFID chip.

Software-based tokens are growing in popularity. And, all mobile phones can operate these token software with ease. Also, tokens are widely used across all platforms thanks to the advancement in web technologies.

Verification Outside of the Band

Out-of-band authentication is a process that uses two separate signals from two different networks or channels for authentication. Authentication based on SMS is one of the most common methods of this type of authentication. In this form of authentication, users receive one-time protection text or password via SMS (text message). After that, the user uses that OTP for further login.

Traditional ways of security are in use with the start of the computing era. Various financial institutions still use traditional security systems for secure working. Because of new and evolving technologies, traditional ways are now getting old. Biometric security systems are now replacing traditional ways of user onboarding securely and efficiently.

Log in to Traditional security system apps:

The user provides login credentials like id and password to log into the app. In-app login requires a user id. In addition, that user id can be any email address, contact number, or any other thing.

Usage of the traditional system:

Traditional security system applies to apps where regular interactions are made.

Traditional security issues:

Passwords no longer provide users with the user security or protection they need. Moreover, with each new cyber-attack, more of our user credentials make their way into the dark web. As a result, cybercriminals can buy them for use in fraudulent activity and unauthorized access. Similarly, traditional ways of securing the data are becoming old. Passwords are easy to hack. This poses a serious traditional security threat to the information.

2: Biometric security system

Since biometric data is non-transferable, unforgettable, distinct, and unique, it has been used for safe identification and authentication. The Biometric verification process depends on the biological traits of human beings. A Biometric system confirms the identity and credentials of a person. Initially, the system stores biometric data. And then Biometric authentication technology compares biometric data captured to previously recorded, verified, and authentic data in a database. 


Biometric systems compare two sets of biometric data: the first is set by the device’s owner, and the second is set by a visitor to the device. What’s important to remember is that the two data sets must be almost similar, but not completely identical. This is because matching biometric data 100 percent is nearly impossible.

In the context of biometric applications, the term “automated methods” applies to 3 specific methods:

  • Scanning and capturing method for the digital or analog image of any personal trait/characteristic
  • Image compression, encoding, and comparison to a database of stored images
  • Interface with applications systems

Besides images and facial recognition, biometric technology uses voice, fingerprints, retina and iris recognition, and the real embodiment of a person.

Biometric and traditional security approaches:

Nowadays, biometrics and security go hand in hand. As a result, every financial institution uses biometric for secure data storage and transactions. In such FinTech systems, to facilitate a sensitive transaction, biometric identifications are used to cross-check and validate the origins. Biometric security systems secure the data. High-end institutions, for instance, agencies and sensitive institutions use such biometric data security systems. As highlighted above, the traditional security system is an easier prey to breach by hackers. Therefore, all the sensitive institutions, financial institutions, and tech companies that have to deal with sensitive transactions are either abolishing the traditional security approaches or using an amalgam of both traditional and biometric systems.

Log in to biometric security system apps:

Users log in with thumbprints or iris scans.

Usage of the biometric system:

Biometric systems apply where high-end security is required. This helps in the FinTech banking system predominantly. Financial institutions also use the biometric system of security. This is useful for secure transactions.

Biometric Characteristics

  • Individuality: no two individuals can have the same characteristic.
  • Universality: exist in the greatest number of people possible.
  • Don’t adjust your performance over time.
  • Measurability: the ability to be measured using basic technical instruments.
  • User-friendliness: they are simple to measure and convenient to use.

Types of biometric security

Fingerprint Recognition

The fingerprint recognition process identifies someone via the markings left by minute ridge formations or patterns found on their skin. On the ends of your fingers, no one (even identical twins) has the same ridge pattern structure. Moreover, no one’s pattern changes over their lifetime.

Geometry of hand

Hand geometry metrics use a three-dimensional representation of the hand. Also, they use the form and length of fingers. This also counts knuckles. Hand geometry is in use for several years. It helps in access control systems. Although the technology does not achieve the highest standards of accuracy, however, it is simple to use and relatively fast in performing user authentication. During the capture process, the user places their hand on the reader and aligns fingers with specially placed guides. The device then reads the hand alignment by beaming infrared light, cross-checks the measurements, and then authenticates.

Recognition of people’s faces

Face recognition software examines the form, pattern, and placement of facial features. This technology is being inspired by human intelligence in terms of remembering the human facial aspects. Face recognition is a complicated technology that relies heavily on machines. Artificial intelligence stimulates face interpretation.  Machine learning is a must to improve accuracy and robustness in such sort of biometrics identification.

The input method for such verification is typically a video stream. Therefore, a standard video camera is sufficient to perform facial recognition. The exact location and angle of the head influences system’s output. Also, the ambient lighting conditions play an important role in user authentication.

Geometry of Fingers

There is an inextricable link between biometrics of finger and hand geometry. Two different capture processes are used to perform biometrics security and user authentication. The first process is identical to the hand geometry as stated above. The second method permits the consumer to insert a finger into the small hole to obtain three-dimensional measurements of the object. 1 or 2 fingers are more than enough to successfully and securely conduct this type of verification.

Scanning the palms

Palm biometrics and, in particular, AFIS technology is similar to finger scanning. Ridges, valleys, and other information of palm helps in palm biometrics. The palm biometrics verification primarily interests the law enforcement domain, so as to run forensics at the crime scenes for palm prints extraction and data validation.


Dynamic signature verification (DSV) is a term for signature biometrics, which examines how we sign our names. It differs from the analysis of static signatures on paper due to its dynamic existence.

The physical signing method derives a variety of characteristics in DSV. Special tablets and pen record signature data. In certain situations, inexpensive equipment also helps. The sound of a pen on the paper also helps in signature biometrics. This technique is referred to as Acoustic emission.

Voice Recognition

Voice biometrics explores the tone of a person’s voice in particular. So, voice detection appears as a separate technology. A similar field of study is speech recognition, which recognizes spoken words and phrases. Voice biometrics also works on the speech recognition principle.


When choosing a biometric device for workers for their daily use, user approval is a critical factor to consider. The following is a list of general user acceptance in descending order, from most to least accepted:

  • Iris scan
  • Keystroke/patterning
  • Signature/handwriting
  • Speaker/voice recognition
  • Facial recognition/face location
  • Fingerprint
  • Hand geometry
  • Retinal scan

Biometric access control system

A biometric access control system scans a person’s specific fingerprint, thumb, face, and retina. The most popular devices are those that scan a person’s fingerprint.  These devices add few additional layers of protection by requiring a password and a key. Suppliers of access control systems offer devices that not only authorize a point of entry but also help monitor users’ interaction. Devices track the time and date they entered the workplace.

Since these smart devices are digital, they are extremely precise. The difference between biometric and traditional access controls is that it provides a higher level of protection. In addition to it uses a digital device to enable people to authenticate themselves without the need for a guide or a leader. This form of access control is the most appropriate on the market if your company requires high standards of protection.

Pros and cons of biometric security:

Many new and old businesses are incorporating biometric security. Fintech businesses and various other organizations use biometric systems for secure transactions. The primary benefit of biometric authentication methods is that they actually verify the user. As a result, the biometric security system is progressing at a great pace. Various fields like forensics use biometrics for criminal tracing and finding, and many other fields have begun to adopt this secure technology. Therefore, ATMs, mobile phones, and other digital and electronic devices also use biometric technology to secure the data and also their users.

Biometric data provide huge customer satisfaction. As a result, many financial and non-financial institutions are moving towards a biometric system of security.
Not only limited to institutions but biometric security is also becoming a part of daily life. And soon biometrics will completely replace the traditional system of security. Passports, ID cards, licenses, doors, and almost everything of daily usage is using this technology.

Disadvantages of Biometrics:

With advantages, there are also many key disadvantages of biometric security systems. This type of system requires hectic installation. Biometrics are slower to use because such systems have limited bandwidth for data retrieval and then matching the biological data with the stored one. Environmental factors also affect this technology. Aging affects biometric validation. The lasers used for biometric are harmful, and daily exposure to lasers can be dangerous.


Traditional and biometric security systems go side by side. The traditional system is now becoming old. Biometrics is successfully replacing traditional security.

In conclusion, biometric security involves the biological traits of a living person and, because technology is advancing, biometrics is the new way of securing data. As a result, all the financial and non-financial institutions are replacing old ways of user authentication. Couple traditional authentication with biometrics and enforce users to enable 2-factor authentication. Added layers of security will bring more safety for your users.
