Recent years have witnessed a significant increase in the level of banking inclusion.

In 2022, around 70% of the population had access to a bank account, up from ~40% a decade earlier, according to the World Bank. This expansion is primarily attributable to the digital revolution.

As of 2014, only 35% of the adult population worldwide could send or receive digital payments; Now this percentage has since risen to around 65%. 

Need for biometric security 

While remote banking provides numerous benefits for financial institutions and clients, it also presents a significant obstacle. Remote banking relies on a level of trust in the identity of the individual accessing the service. But that is also a challenge,
as that trust is exploited by cyber-enabled crime. 

As banks expand remote access to digital services and make access more accessible for users, it becomes a way for fraudsters to steal data and engage in cyber-crimes. 

So, while on the one hand, for financial inclusion and the overall good of society, we need to extend the banking and financial services to each segment of society, we also need to put enough guardrails so that the data of these individuals is not
stolen and no fraud happens. 

Indeed, financial institutions are under constant pressure from all directions; customers anticipate using their mobile devices to initiate bank accounts and conduct other transactions.

Concurrently, criminals carry out fraudulent activities and security breaches via digital platforms. Financial institutions confront the concurrent risk of incurring penalties for compliance with KYC and AML regulations.

As a reaction, many financial establishments are adopting sophisticated verification systems to register and authenticate the rapidly expanding group of online bank customers.

This necessitates substituting laborious manual procedures and antiquated authentication techniques, such as implementing passcodes and passwords.

By explicitly integrating biometric verification technology, financial institutions can optimize customer inclusion, reduce user frustration, ensure regulatory compliance, and proactively detect fraudulent activities. Conversely, only some solutions offer
an equivalent degree of security.

Interesting Aspects of the Financial Industry’s Biometric Security Function:

1. Biometrics addresses the shortcomings of conventional passwords by employing dynamic and one-of-a-kind authentication techniques that rely on intrinsic physical or behavioral characteristics.

One may contemplate the potential of employing a biometric scan to gain access to their bank account or authorizing a transaction via vocal command—substituting vulnerable character sequences with their unalterable identity.

2. By deterring unauthorized access and financial crime, biometric security improves fraud prevention measures. Multiple authentication factors effectively fortify security measures against fraudulent attempts to impersonate authorized users,
protecting sensitive data and financial transactions.

3. User Experience Improvement: Biometric authentication ensures minimal disruption to the user’s experience while providing an additional layer of security.

One could envision the feasibility of authorizing payments or accessing investment portfolios through a retinal scan or the flicker of an eye. This innovation would simplify financial transactions and eliminate the necessity for laborious passwords or security
codes.

Role of Biometric Security in the Financial Sector:

Biometrics has the potential to serve as an alternative method of authentication, contributing to the efforts of financial institutions to prevent fraud and ensure regulatory compliance.

As a result, the financial sector is impacted by this technological innovation, which is replacing passwords and establishing itself as the leading technological solution for Know Your Customer (KYC) and fraud prevention owing to its intuitive interface. 

Biometrics in banking uses individuals’ unique physiological or behavioral characteristics for authentication and security purposes in digital banking transactions and account access.

In addition to the abovementioned characteristics, biometric scanning, retinal recognition, facial recognition, and voice recognition may also be included.

Knowledge-based authentication methods, including one-time passwords  and PINs, are susceptible to theft and neglect. On the other hand, contemporary digital payment systems prioritize biometric verification methods to a considerable extent, enabling users
to gain entry to their accounts solely based on their unique biological characteristics.

Face recognition is a technological process utilized to ascertain an individual’s identity by analyzing facial characteristics. Institutions frequently obtain this data through the use of photographs or recordings. An individual is identified
by comparing the information provided and a database comprising accumulated photographs.

Prominent illustrations of biometric payment systems are Apple Pay and Google Pay. They enable customers to utilize Touch ID or Face ID to finalize purchases.

In addition to enhancing identity assurance to comply with regulations, biometric identity verification acts as a formidable deterrent to fraudulent activities. Notably, it verifies the account holder’s identity more effectively than conventional methods
utilized by organizations to prevent fraudulent transactions. 

The Javelin Identity Fraud Report provides businesses, financial institutions, government agencies, and other organizations with an in-depth and comprehensive examination of identity fraud and the success rates of prevention, detection, and resolution methods.

It reveals that approximately 22% of U.S. adults, or 24 million households, have experienced account takeover (ATO) incidents.

To prevent and address such fraudulent activities and assaults, particularly those related to identity theft, financial institutions implement multi-factor authentication (MFA) systems. These systems integrate biometric verification with additional security
measures like PINs or passwords. This dual-pronged security strategy enhances safeguards by necessitating user authentication via biometric attributes and user knowledge (e.g., password).

Biometric security is of the utmost importance in bolstering the digital defense of the financial sector as financial technology continues to evolve.

This state-of-the-art technology verifies and authenticates users’ identities by utilizing distinct physiological or behavioral attributes, initiating a period characterized by enhanced security protocols and streamlined user interactions.

Globally, biometric banking systems possessed a market capitalization of $5 billion in 2022. The industry is projected to have a significant valuation of $23.6 billion by 2032, expanding at a compound annual growth rate (CAGR) of 17.2% between 2023 and 2032.

History:

Although biometric identification has been used for centuries, its widespread adoption in the financial sector signifies a substantial progression.

Citibank and other early advocates of biometric technology conducted experiments in the early 1990s using fingerprint scanners to authorize access to ATMs. These endeavors established the foundation for subsequent biometric applications.

To enhance security during the 2000s, HSBC and other financial institutions adopted iris recognition technology. Gemalto and Safran emerge as market champions in the biometric solutions sector.

Face recognition and voice authentication have experienced a notable surge in adoption within physical branch authentication, online transactions, and mobile banking since the 2010s. Integrating biometric security into mainstream operations has been advanced
with the introduction of facial and fingerprint recognition for contactless transactions via Google Pay and Apple Pay.

How it Works:

Biometric security functions by employing individuals’ identifier and verifier capabilities, which are determined by their distinct biological or behavioral attributes. The following is a concise overview of the operational mechanisms underlying biometric
security in the financial industry:

1. Biometric data associated with users, including facial features, biometrics, and voice attributes, is stored securely in a database throughout the enrollment procedure.

2. Initiating a transaction or acquiring access to a financial system requires authentication; this is accomplished by the system retrieving the user’s biometric information and comparing it to a template that was previously stored.

3. The matching algorithm, which is of an advanced nature, compares the biometric data that has been captured with the template that has been recorded. After evaluating the degree of similarity, the system produces a confidence score.

4. Whether Access Is Granted or Denied: The system determines access status based on the confidence score. The requested action is authorized, and the user is authenticated upon a successful match.

5. Ongoing Enhancement: Certain biometric systems integrate machine learning methodologies to guarantee a steady progression in precision. The system assures dependability through progressive learning and adaptation to changes in the biometric
characteristics of the user.

As a result of the ongoing advancements in biometric technology, implementing multi-factor authentication, which incorporates multiple biometric modalities, is required to accommodate the growing prevalence of security measures.

The National Institute of Standards and Technology (NIST) concluded in a study conducted in 2023 that fingerprint recognition demonstrates exceptional accuracy and reliability, as evidenced by its 0.001% False Acceptance Rate (FAR).

The technological systems and methodologies employed may differ according to the biometric modality (e.g., voice, fingerprint, iris, etc.) and the intended degree of security. Nevertheless, the fundamental tenet remains unaltered: capitalizing on distinctive
and unchangeable human attributes to facilitate secure and streamlined financial transactions.

Use Cases of the Role of Biometric Security in the Financial Sector:

Customer Onboarding

Identity verification is the initial and pivotal phase in the registration procedure for a remote consumer. Financial institutions employ this method to verify that they deal with legitimate consumers at the outset. This enables them to promptly identify
and exclude potential fraudulent identities, algorithms, and malicious actors, in addition to assisting compliance efforts (by demonstrating that they “know” their consumers).

Financial institutions can eliminate the necessity for in-person interaction with clients by employing a brief biometric facial scan after digitizing a trusted identity document, such as a driver’s license, to verify client identity.

The onboarding phase is considered the most vulnerable because information about the user or their risk is inaccessible after enrollment.

As a result, it is critical to implement the highest standards of identity verification to protect against risks like synthetic identity fraud. Recruiting fosters the development of enduring trust that remains throughout the customer’s lifecycle.

Customer Authentication

Legitimate onboarding does not preclude the possibility of account acquisition fraud, identity theft, phishing, or any other fraudulent activity gaining access to the account. Using biometric facial authentication, it is possible to verify that the user 
persistently attempting to access an account is, in fact, the same person who created the account.

Re-authentication is feasible after an individual’s identity has been verified with the utmost certainty through a relatively lax process and a straightforward liveness check, provided that no modifications have transpired that would increase the risk.

This occurs when an authorized user is added to a consumer’s account, a new line of credit is requested, a password reset is requested, a new device is configured, or an existing device is returned.

Following this, a financial institution may choose to enhance the level of authentication by requiring an additional biometric scan to verify the consumer’s identity, performing the abovementioned changes. This capability empowers financial institutions
to provide consumers with the necessary flexibility and convenience.

By drawing a comparison to how biometric security protects users’ banking information (similar to the process used to access a smartphone using fingerprint or facial recognition) in the financial industry, this technology provides a combination of security
and convenience.

One could establish a parallel between how biometrics optimize airport security protocols and how they enable timely and secure access to financial accounts, reducing the likelihood of illicit entry.
