Knowledge-Based Authentication (KBA)

Knowledge-based authentication (KBA) is a traditional method for user verification that relies on a user's knowledge of secret information. This typically involves passwords and security questions.

The Prevalence of KBA

• Simplicity: KBA is easy to implement and use for both users and organisations.
• Familiarity: Users are accustomed to using passwords and security questions for online accounts.

Limitations of KBA

• Vulnerability to Social Engineering: Security questions can be susceptible to social engineering attacks, where attackers manipulate individuals into divulging confidential information.
• Weak Passwords: Many users create weak or easily guessable passwords, compromising security.
• Risk of Credential Theft: Stolen passwords or leaked databases can severely compromise KBA security.

KBA and Multi-Factor Authentication (MFA)

While KBA alone might not be sufficient for high-security applications, it can still be part of a multi-factor authentication (MFA) strategy. MFA combines KBA with other authentication factors, such as:

• Possession Factors: One-time codes received via SMS or generated by an authentication app.
• Biometric Factors: Fingerprint scans, facial recognition, or iris recognition.

Smile ID’s Approach to Secure Authentication

At Smile ID, we understand the importance of robust and reliable identity verification. While KBA can provide an initial layer of security, it is not sufficient on its own in today’s threat landscape.

1. Integrated MFA Solutions: Smile ID advocates for the integration of KBA with more secure methods as part of a comprehensive MFA approach. Our solutions combine traditional KBA with advanced biometric verification methods such as facial recognition and liveness detection. This layered security ensures a higher level of protection against fraud and unauthorised access.

2. Advanced Biometric Verification: Smile ID’s proprietary technology, SmartSelfie™, leverages active liveness detection to ensure the person presenting is a live human being. This technology reduces the risks associated with traditional KBA by adding a biometric layer that is significantly harder to spoof.

3. Comprehensive Identity Verification: Smile ID’s solutions are designed to provide seamless and secure identity verification across various industries. By combining KBA with biometrics and other possession factors, we deliver a robust authentication system that meets the needs of modern digital security.

Conclusion

Knowledge-based authentication remains a common method, but understanding its limitations is crucial. By implementing KBA as part of a robust MFA strategy, organisations can strengthen their security posture and protect user identities in the digital age. Smile ID is committed to providing secure and convenient identity verification solutions, with MFA being a key element in achieving that goal.
