Proof of Life: Validating Identity in Real-Time 

The need for proof of life has become undeniable—how can we be sure that the person on the other end is real, not a cleverly engineered imitation?

Fraudsters are continuously finding new ways to deceive authentication systems. From deepfake audio to sophisticated replay attacks, organizations are now grappling with how to ensure that the person on the other end of a device is not only human but also legitimate. ValidSoft stands at the forefront of security innovation, with every solution—across diverse applications—united by a single purpose: ensuring proof of life.

Voice Biometrics Liveness Testing

Traditionally, speech recognition systems have been tasked with recognizing what is said—the words spoken. On the other hand, speaker recognition focuses on identifying who is speaking using voice biometric technology. By combining these two technologies you achieve, conversational voice biometrics which enables us to simultaneously verify who is speaking and what they are saying. This dual approach is essential in today’s cybersecurity environment, especially for implementing liveness testing and securely authenticating the genuine user in real-time while also giving the user an experience that is as seamless, secure, and easy as possible.

Conversational liveness testing ensures that a real, live human is on the other end of the interaction, rather than pre-recorded or synthetically generated audio. It replaces repetition of static phrases (eg “my password is my voice”) and other traditional methods such as knowledge-based-authentication (KBA), which fraudsters have increasingly found ways to bypass through social engineering and automated attacks. This technology is invaluable for securing customer interactions, especially in high-risk sectors and industries from banking to healthcare.

Real-World Examples: The Current Landscape of Threats

Recent incidents highlight the urgency of these solutions. In a past incident, a major financial institution faced a sophisticated deepfake scam, where AI-generated audio of a company executive’s voice was used to authorize a fraudulent transfer of millions. This case is now one of many and underscores how advanced fraud tactics have become, making it harder to differentiate between legitimate and synthetic voices.

Additionally, cybercriminals have recently leveraged voice-bots to steal 2FA codes by tricking victims into revealing sensitive authentication data. These attacks highlight the limitations of traditional methods, such as one-time passwords (OTP) or knowledge-based verification questions. As hackers become more adept at deploying automated attacks, ensuring a “proof of life” on the other end of the line becomes critical for preventing these kinds of breaches.

Achieving Universal Proof of Life

All our solutions, no matter the use case, ensure proof of line as a fundamental necessity in our security models. At ValidSoft, we’ve pioneered advanced voice-based authentication technologies to address these types of threats. Our solutions leverage Conversational Voice Biometrics to prove that the person on the other end is not only human but the authorized individual. Our approach to liveness testing ensures that a fraudster cannot deceive the system by playing pre-recorded audio or using deepfake technology.

Our See-Say® solution ensures the safest, easiest way to authenticate users. It uniquely addresses liveness and proof of life by using a clever combination of math and cryptography. For the first time ever, it achieves irrevocability, non-repudiation, and data immutability while ensuring ease of use and intuitiveness.

When combating deepfakes and ensuring proof of life in an era of AI fraud and deception, our patented Voice Verity® solution also goes a step further by incorporating state-of-the-art generative AI deepfake audio detection, ensuring real-time and batch processing capabilities for audio authentication. This provides peace of mind to businesses and institutions that are constantly threatened by deepfake audio attacks, synthetic speech, spoofing, and replay attacks.

An Essential Layer of Protection

Two-factor authentication (2FA) and multi-factor authentication (MFA) have long been the go-to methods for securing online transactions and phone-based interactions. However, hackers can now intercept and manipulate traditional security measures, making proof of life and passive conversational voice biometrics an essential layer of protection.

Speaker recognition, coupled with speech recognition, enhances the security of call centers, financial services, and customer service interactions by preventing unauthorized access and fraudulent activity. Voice-based authentication offers a frictionless, language and device-agnostic solution, applicable anywhere and capable of thwarting man-in-the-middle, spoofing, and replay attacks.

Future Applications of Voice-Based Authentication

Beyond financial services and call centers, voice-based authentication is poised to play a critical role in sectors like telemedicine. As healthcare continues to move into the digital realm, ensuring that a doctor or patient on the other end of a virtual consultation is the authentic human, becomes paramount. The versatility and scalability of conversational voice biometrics make it the ideal solution for this and other emerging industries. The use cases for proof of life systems regarding authentication are far and wide. Proving identity is the first and most important step in ensuring organizations and customers are protected from criminal fraud tactics.

Securing the Future with ValidSoft

Fraudsters aren’t going away anytime soon. Their tactics are becoming more sophisticated, and organizations need to adapt quickly to keep pace. Proof of Life is a powerful tool for ensuring that the person on the other end of the phone is human and authorized to act. ValidSoft’s cutting-edge solutions help businesses establish trust and verification in an increasingly deceptive world.

By incorporating liveness, deepfake audio detection, and advanced voice recognition technology, ValidSoft ensures that you can always be certain of the identity and authenticity of the voice on the other end of the line.
