Biometric authentication is a way to confirm a person’s identity. In other words, they can locate each other based on their unique physical characteristics. Especially, this can include fingerprints, facial recognition, iris scans, and voice recognition.
Normally, a guy might use their fingerprint instead of a passcode to unlock their phone. To clarify, assume this scenario. The CEO of your organization is trying to gain entry into the secured office building. For instance, he might use his face scan, fingerprint, or iris scan to gain entry. In spite of, showing an ID card.
In these circumstances, biometric authentication begins as the first step of the identification. It starts with the person providing a sample of their biometric trait. Thus, to verify their identity, we take a fingerprint or scan of their face or iris.
Biometric authentication has better security than a password or ID card. Despite these challenges, biometrics remain practical. For instance, consider the privacy and security of stored data. By all means, the features might not be accessible to people with specific disabilities.
What is Biometric Authentication? Definition and Examples
Biometric authentication is a security process that verifies identity using unique physical or behavioral characteristics—such as fingerprints, facial features, iris patterns, or voice—instead of passwords or PINs. According to industry standards, biometric systems achieve 99.8% accuracy rates for fingerprint recognition and 99.6% for facial recognition, making them significantly more secure than traditional password-based systems which are compromised in 81% of data breaches.
The definitive advantage: Biometric data cannot be forgotten, lost, or easily stolen like passwords. However, the primary disadvantage is that once biometric data is compromised, it cannot be reset or changed like a password can.
When someone logs in, biometric identification uses their unique bodily traits to make sure they are who they say they are. These traits, like fingerprints, face features, iris patterns, or even voice patterns, are hard to copy or fake, so they can be used to prove someone’s identity. In most biometric identification systems, a sample of the user’s biometric data is taken and stored safely and then compared to other examples when the user tries to log in. If the samples match, the person can get in. If they don’t, they can’t.
Here are some of the key points from the article:
- Biometric authentication uses unique physical characteristics to identify a person.
- Biometric authentication is more secure than passwords or PINs.
- Biometric authentication is faster and more convenient than passwords or PINs.
- Biometric authentication can be expensive.
- There are privacy concerns associated with biometric authentication.
How Does Biometric Authentication Work? 3-Step Process ExplainedfMethods of Biometric Authentication?
| Metric | Biometric Authentication | Traditional Passwords |
| Security Breach Rate | <0.1% false acceptance | 81% of breaches involve passwords |
| User Authentication Time | 1-2 seconds | 15-30 seconds average |
| Cannot Be Lost/Forgotten | ✓ Always with you | ✗ 78% forget passwords monthly |
| Can Be Reset if Compromised | ✗ Permanent data | ✓ Easily changed |
| Implementation Cost | $50-$10,000 per point | $5-$20 per user |
| User Preference Rate | 87% prefer biometric | 13% prefer password-only |
Bottom Line: Biometric authentication offers superior security and convenience but requires higher upfront investment and cannot be reset if compromised.
This authentication system captures a biological data sample from a user. Then they compare the data to a stored model to verify the user’s identity. Following are the steps to complete the procedure:
Step 1:
To start the process, the user presents their biometric characteristics to the identification device. In brief, there are three types of scanners. i.e., facial scanners, fingerprint scanners, and microphones.
Step 2:
Second, the process captures the biometric sample. Then, converts its data into a digital template. This template represents a biometric characteristic mathematically.
Step 3:
Next, the software compares the captured template to the stored template. Thereafter, the platform verifies the user’s identity and grants access if the templates match. On the contrary, if the templates do not match, the algorithm denies access. The user may need to try again or use an alternative authentication method.

Fingerprint Authentication:
This method involves scanning a person’s fingerprint to confirm their identity. This time, A camera captures an image of the fingerprint. That is, to compare the image to a before-stored version to see if they match.
Facial Recognition:
This method uses a camera to capture a picture of someone’s face. Afterward, the system compares it to the stored data of that person’s face.
Iris Recognition:
This method uses a camera to capture an image of a person’s iris. Specifically, it captures the colored part of the eye. So that, the unique patterns in the iris confirm a person’s identity.
Voice Recognition:
This method involves capturing a sample of a person’s voice and comparing the sample to a before-recorded version to confirm their identity.
Hand geometry:
This method captures the size and shape of a person’s hand to confirm their identity. Based on the measurement of the lengths of the fingers, the hand’s breadth, and the hand’s shape.
Signature Dynamics:
This method captures a person’s signature to confirm their identity. Using a signature analysis program, it is possible to find how a person writes their signature. Such as their speed, pressure, and the angle of the pen on the paper.
Gait Recognition:
It’s possible to capture someone’s walk with a camera. Use this method to determine how they walk. Analyzes factors such as how they move and their stride length to confirm their identity.
Behavioral biometrics:
This method captures a person’s typing/mouse movement pattern to confirm their identity. Based on the way a person moves or interacts with their devices.
How to Choose Between Biometric Authentication Methods
Selecting the right biometric authentication method depends on five critical factors:
1. Security Requirements

When evaluating biometric authentication providers, prioritize those offering comprehensive business system integration rather than standalone security products.
Advantages and Disadvantages of Biometric Authentication [2025 Analysis]
Biometric authentication has revolutionized security systems, but it comes with both benefits and limitations. Here’s a breakdown:
Benefits of Biometric Authentication
Research consistently shows that biometric authentication delivers four measurable benefits: (1) Enhanced security with false acceptance rates below 0.001% for modern systems, (2) Time savings of 15-30 seconds per authentication compared to passwords, (3) Cost reduction of up to 80% in password reset support tickets, and (4) Improved user experience with 87% of users preferring biometric login over traditional methods. Here are some advantages of biometric authentication:
1. Increased Security:
Plenty of biometric methods are available today. Such as fingerprint scanning or facial recognition. Traditional methods aren’t as secure as these. Such as passwords or PINs. Because they are unique to the individual, and no one can replicate or steal them.
2. Convenience:
Biometric methods can be faster and more convenient for users. They do not need to remember passwords or carry physical tokens such as keycards or tokens.
3. Improved Accuracy:
Biometric methods can be more correct than traditional methods. They rely on unique physical characteristics that no one can forge or copy. Also, it helps with payroll management accuracy.
4. Enhanced User Experience:
This authentication can improve the user experience by providing a seamless and hassle-free login procedure.
What Are the Disadvantages of Biometric Authentication?
The disadvantages of biometric authentication fall into five critical categories that organizations must evaluate before implementation. While biometric systems offer superior security compared to passwords, these limitations can significantly impact deployment decisions, user acceptance, and long-term operational costs.
Biometric Authentication Cost Analysis: What to Expect in 2025
1. High Implementation and Maintenance Costs
Biometric authentication systems require substantial upfront investment ranging from $3,000 to $10,000 per enterprise access point, including:
- Specialized hardware (scanners, cameras, sensors): $500-$5,000 per unit
- Software licenses and integration: $10,000-$100,000 for enterprise systems
- Infrastructure upgrades (network, storage, servers): $20,000-$200,000
- Staff training and change management: $500-$2,000 per employee
- Ongoing maintenance fees: 15-20% of initial investment annually
For small businesses with 50 employees, total first-year costs typically range from $15,000-$75,000, compared to $500-$2,500 for password-based systems.
2. Irreversible Data Compromise
Unlike passwords, biometric data cannot be reset or changed if compromised. Key concerns include:
- Permanent vulnerability: Once your fingerprint template is stolen, you cannot grow new fingerprints
- Lifetime exposure: A single data breach can enable identity fraud for your entire life
- Cross-system risk: The same biometric (your face, fingerprint) used across multiple systems creates cascading vulnerability
- Template attacks: Even encrypted biometric templates, if stolen, can potentially be reverse-engineered with sufficient computing power
According to cybersecurity research, 23 million biometric records were compromised in data breaches between 2019-2023, affecting individuals permanently.
3. Technical Failures and Accuracy Issues
Biometric systems experience two types of errors that impact usability:
False Rejection Rate (FRR) – Legitimate users denied access:
- Fingerprint: 0.1-3% rejection rate (3-30 out of 1,000 legitimate attempts fail)
- Facial recognition: 0.5-5% in poor lighting or with accessories
- Voice recognition: 2-8% during illness or in noisy environments
- Iris scanning: 0.01-0.5% with contact lenses or eye conditions
False Acceptance Rate (FAR) – Unauthorized users granted access:
- Basic fingerprint systems: 0.001-0.1% (1-100 per 100,000 attempts)
- Consumer facial recognition: 0.01-1% vulnerability to spoofing
- Advanced iris systems: 0.00001% (1 in 10 million)
Environmental factors significantly increase failure rates:
- Wet or dirty fingers reduce fingerprint accuracy by 40-60%
- Poor lighting decreases facial recognition accuracy by 25-50%
- Background noise increases voice recognition errors by 30-70%
- Injuries, aging, and medical conditions can permanently affect biometric accuracy
4. Privacy and Surveillance Concerns
Biometric authentication raises significant privacy issues that affect user adoption:
- 64% of consumers express concerns about biometric data storage and usage
- Data permanence: Biometric information is identifiable and linkable across databases
- Surveillance potential: Facial recognition enables tracking without consent
- Third-party access: Questions about who can access stored biometric databases
- Legal ambiguity: In some jurisdictions, biometric data has weaker legal protection than passwords
- Function creep: Systems deployed for authentication being repurposed for surveillance
The EU’s GDPR classifies biometric data as “sensitive personal data” requiring explicit consent and enhanced protection. However, enforcement and user control remain challenging.
5. Accessibility and Inclusivity Barriers
Approximately 2-5% of the population cannot effectively use certain biometric methods:
- Fingerprint issues: Worn fingerprints (elderly, manual laborers), hand injuries, or genetic conditions affecting ridge patterns
- Facial recognition challenges: Facial differences, scarring, progressive conditions, or religious head coverings
- Iris scanning limitations: Cataracts, eye injuries, or photosensitivity conditions
- Voice recognition barriers: Speech impediments, throat conditions, or selective mutism
- Gait recognition problems: Mobility disabilities, injuries, or assistive devices
Organizations must provide alternative authentication methods, adding complexity and cost. The Americans with Disabilities Act (ADA) requires reasonable accommodations, meaning biometric-only systems may face legal challenges.
6. Vendor Lock-in and Interoperability Issues
Additional disadvantages include:
- Proprietary systems: Biometric templates often cannot transfer between vendors
- Migration costs: Switching providers requires re-enrollment of all users ($10-$50 per user)
- Standard limitations: Lack of universal biometric data formats
- Integration complexity: Difficulty connecting with existing security infrastructure
Bottom line: While biometric authentication offers measurable security improvements, these six disadvantages require careful evaluation. Organizations should conduct cost-benefit analysis, privacy impact assessments, and pilot testing before full deployment.
The data confirms five primary limitations of biometric authentication: (1) High initial costs ranging from $3,000-$10,000 per access point for enterprise systems, (2) Irreversible data compromise—unlike passwords, biometric data cannot be reset if stolen, (3) False rejection rates of 0.1-3% that can lock out legitimate users, (4) Privacy concerns with 64% of users worried about biometric data storage, and (5) Accessibility issues for approximately 2-5% of the population with certain disabilities or injuries.
1. Cost:
This type of system can be quite expensive to start and keep. We need specialized hardware and software to capture and verify biometric data.
2. Privacy Concerns:
This might concern the people about the privacy implications of securing authentication with biometrics. As a whole, it involves the collection and storage of personal information. As an example, we can use fingerprints or facial images to find a person.
3. Technical Issues:
It’s possible to compromise biometric authentication methods. To technical issues such as false negatives. (Rejecting a valid user) or false positives (accepting an invalid user).
4. Lack of Universality:
This authentication method may only be suitable for this. Because of their physical characteristics, the people may not meet these requirements. (Such as fingerprints) or may have disabilities. That prevents them from using specific methods.

Conclusion
The last time biometrics were used to verify identities was centuries ago. The first recorded use of biometric identification was in ancient Babylon, where they used fingerprints to sign documents and seal business transactions.
Biometrics played an influential role in security during the 20th century. Cops used fingerprints to identify criminals and match them to crimes in the 1970s. To control access to secure facilities, they developed the first biometric security systems in the 1980s.
In the 1990s, technological advances developed into more sophisticated biometric authentication methods, such as iris scanning and facial recognition. People use these methods in high-security environments. Such as government agencies and military bases. Still, they became more adopted in commercial and consumer applications.
In the 21st century, biometrics have become prevalent. Smartphones and other devices now feature fingerprint scanners—and facial recognition software to unlock screens and protect access to personal data. There are also a lot of industries that use it. Including banking, healthcare, and transportation, to improve security and convenience for users.
Technology for biometric security is evolving. People will develop this in broader applications. The experts predict that this way of authentication will replace traditional methods. Such as passwords and PINs, as the primary means of verifying identity.

What are the disadvantages of biometric authentication?
Disadvantages include high implementation costs, privacy concerns, and technical issues such as failed authentication in edge cases. Additionally, biometric data cannot be reset if compromised.
How does biometric authentication work?
Biometric authentication works by capturing a person’s unique physical or behavioral traits (e.g., fingerprints or facial features) through sensors. These traits are stored as templates and compared during authentication to verify identity.
Is biometric authentication better than traditional methods like passwords?
Yes, biometric authentication is more secure and convenient than traditional methods like passwords or PINs. It eliminates risks associated with forgotten passwords and reduces vulnerability to hacking attempts.
Can biometric data be stolen or misused?
While biometric data is harder to steal than passwords, it is not immune to breaches. Storing biometric data locally instead of on centralized servers can reduce risks of misuse.
What are the risks associated with biometric authentication?
Risks include data breaches, privacy concerns, inaccuracies due to biased training data, and system failures in certain conditions (e.g., wet fingerprints or sore throats affecting voice recognition).
How much does biometric authentication cost to implement?
Biometric authentication costs vary significantly by scale and technology. For small businesses, individual biometric devices (fingerprint or facial recognition scanners) range from $50-$500 per unit. For enterprise implementations, expect $3,000-$10,000 per access point including hardware, software licenses, and integration. Complete organizational rollouts typically cost $50-$200 per employee for hardware, plus $20,000-$100,000 for centralized management software. Cloud-based biometric authentication services offer subscription models starting at $2-$5 per user per month, eliminating large upfront investments. Additional costs include staff training ($500-$2,000), ongoing maintenance (15-20% of initial cost annually), and system upgrades every 3-5 years.
Is biometric authentication better than passwords?
Yes, biometric authentication is measurably superior to passwords in security and convenience. Studies confirm that 81% of data breaches involve weak or stolen passwords, while biometric systems have false acceptance rates below 0.001%. Users save 15-30 seconds per login compared to password entry, and organizations reduce password reset support costs by up to 80%. However, passwords remain better for privacy-conscious users and scenarios requiring anonymity, as biometric data is inherently identifiable. The optimal approach for high-security environments is multi-factor authentication combining biometrics with passwords or security tokens, providing security rates above 99.9%.
What happens if my biometric data is stolen?
If biometric data is stolen, the consequences are more severe than password theft because biometric data cannot be changed. The primary risk is permanent identity fraud—criminals could potentially use stolen biometric templates to impersonate you across multiple systems. However, most modern systems store encrypted “templates” rather than actual biometric images, limiting misuse. To protect yourself: (1) Use systems that store biometric data locally on your device rather than centralized databases, (2) Enable multi-factor authentication combining biometrics with other security methods, (3) Monitor accounts for unauthorized access, and (4) Avoid providing biometric data to unverified or low-security applications. Organizations using biometric systems must encrypt templates using AES-256 or equivalent standards and implement template protection algorithms that make stolen data computationally infeasible to reverse-engineer.
Can biometric authentication integrate with payroll and HR systems in Bangladesh?
Yes, modern biometric authentication systems in Bangladesh can fully integrate with payroll and HR management software. Integration enables automated attendance tracking, eliminates timesheet errors, ensures labor law compliance for working hours documentation, and reduces payroll processing time by 70-80%. When selecting a biometric system, verify it supports API integration with your existing HR software or offers comprehensive HRIS functionality including payroll, attendance, leave management, and compliance reporting in a single platform. This integration typically reduces HR administrative costs by 40-60% while improving payroll accuracy by 15-25%.
