Exploration of Identity Authentication Development and the Most Robust Verification Techniques
In the digital age, identity verification has become a crucial aspect of ensuring security and compliance. Here's a journey through the history and current best practices of identity verification.
The Roots of Identity Verification
The practice of verifying identities can be traced back as far as 100,000 years ago, with archaeological discoveries suggesting that distinctive goods and markers of identity were used for verification purposes. Fast forward to the Babylonian Empire, where the first recorded census took place, marking an early form of personal information collection.
From Passwords to Biometrics
The first computer password was created in 1960, signalling a significant breakthrough in verification technologies. However, it wasn't until the 2010s that advanced biometric systems, such as fingerprint and face verification, started becoming common, particularly through mobile technology.
The Modern Landscape
Current best practices for identity verification emphasize a combination of advanced biometrics, liveness detection, multi-factor authentication (MFA), document and address verification, and AI-driven fraud prevention. These methods prioritize both security and user experience across digital environments.
Biometric Verification with Liveness Checks
Increasingly critical due to the rise in forged IDs and deepfakes, face biometrics combined with AI-powered liveness detection confirm that the person is real and present, not using static images or videos. This method is widely adopted in financial sectors and preferred by many consumers for its balance of security and ease of use.
Document Authentication
Automated Optical Character Recognition (OCR), barcode/QR code reading, and NFC chip verification on government-issued IDs validate document authenticity. This process often includes cryptographic signatures embedded in documents to detect tampering swiftly.
Address Verification
Implementing multi-layered approaches that combine official documents (utility bills, bank statements) with authoritative database look-ups (e.g., national ID registries, credit bureaus) for proof of residence enhances fraud control and regulatory compliance. Continuous monitoring and dynamic proof-of-address flows are recommended.
Multi-Factor Authentication (MFA) and Passkeys
Strengthening verification by requiring multiple authentication factors, including biometric, device-based, and knowledge factors, improves security. Transitioning toward passkeys and digital credentials stored in user-controlled digital wallets improves security and user convenience, reducing reliance on vulnerability-prone methods like SMS-based verification.
AI-driven Fraud Detection
Leveraging AI to detect synthetic identities, deepfakes, and spoofing attempts in real time is a key component of modern KYC solutions. These solutions integrate AI to provide sub-second verification while maintaining privacy-first architectures.
Device Compatibility and User Experience
Solutions must be compatible with standard consumer devices (smartphones, tablets) to maximise accessibility without requiring specialized hardware, ensuring seamless onboarding and verification flows.
The Future of Identity Verification
Document-free verification is being adopted by more countries as a way to simplify onboarding. Sumsub's Non-Doc Verification solution, available to over 90% of users from several countries, can be customized to meet country-specific requirements, offering a flexible approach to identity verification.
In the Netherlands, users need to get verified through a government app, while in the UK, users log into their bank account and agree to share personal data. These examples illustrate the diverse methods used for identity verification across the globe.
As we move forward, the focus will remain on balancing security and user experience, with the goal of providing a smooth and efficient verification process for all.

[5] The Importance of User Experience in Identity Verification
- In the financial sector, the preference for improved security and user convenience leads to an increased adoption of advanced biometrics, such as fingerprint and face verification, and AI-powered liveness detection, especially through cloud-based technology and data-and-cloud-computing solutions.
- As the landscape evolves, the use of AI in identity verification becomes more prevalent, not only for detecting fraud but also for streamlining the KYC (Know Your Customer) process, ensuring fast and secure onboarding while maintaining privacy for business transactions.
