You’re logging into your online banking account, and the system uses MFA to verify your identity. You feel secure, knowing that biometric authentication is nearly foolproof. But is it? As we dive deeper into the world of digital transactions, we’re facing an increasing threat from AI-generated deepfakes that challenge even our most sophisticated identity verification systems.
Gartner analysts warn, “Identity verification leaders must understand this emerging threat and take a proactive approach to secure their solutions.”
The security of our identities has never been more crucial. Presentation and injection attacks are posing new risks, especially with the rise of deepfakes. Let’s explore what this means and how we can counter these attacks.

The security of our identities has never been more crucial. Presentation and injection attacks are posing new risks, especially with the rise of deepfakes. Let’s explore what this means and how we can counter these attacks.
Understanding Presentation Attacks
Presentation attacks, often called spoofing, involve tricking biometric systems using deceptive biometric samples. These could be photos, videos, or other replicas intended to mimic a legitimate user. Historically, biometric systems have relied on static detection methods to identify these fakes. However, deepfakes have revolutionised this landscape. With the incredible precision of deepfake technology, attackers can create videos that convincingly simulate live actions and facial behaviors, effectively bypassing traditional detection methods.
The Critical Role of Liveness Detection
So how do we tackle these advanced presentation attacks? One effective technique is liveness detection. This technology ensures that biometric systems can differentiate between a live person and a static image or pre-recorded video. Liveness detection systems analyse natural facial expressions and eye movements, which are hard to replicate perfectly in deepfakes.
During the verification process, users may be asked to perform specific actions, like blinking or turning their head, ensuring the presence of a live person. Moreover, it assesses the three-dimensional structure of the face, making it tough for flat images or videos to pass as real.
Additionally, it examines skin texture and how light reflects off the face. These characteristics are unique to real human skin and difficult for deepfakes to mimic.
The Menace of Injection Attacks
Even as liveness detection evolves, attackers have found new ways to deceive these systems through injection attacks. Unlike presentation attacks, injection attacks involve manipulating the data being sent to the authentication system. Attackers might use virtual camera software, like Manycams, to feed pre-recorded or synthetic videos into the system as if they were live feeds.
They could also alter the browser’s code to bypass security protocols and insert fraudulent data. Furthermore, some attackers intercept communication between a browser and server, performing a classic “Man in the Middle” attack to manipulate data.
One such solution leverages the front-facing camera on mobile devices to record a user’s video, conducting a liveness check to ensure the individual is genuine. Once verified, a selfie is captured as a biometric reference for future logins. This continuous verification process makes it significantly harder for attackers to bypass the system with deepfakes.

Advanced Security Solutions
With the growing sophistication of these attacks, the demand for advanced security solutions is more pressing than ever. Innovative technologies have emerged to address this challenge effectively. Building on this foundation, more advanced solutions provide an even higher level of protection by actively identifying and blocking injection attacks in real-time.
These client-side solutions employ advanced algorithms to detect anomalies or manipulations during the verification process. If suspicious activity is detected, the system halts the authentication attempt immediately, ensuring robust security against sophisticated cyber threats.
Building a Future-Proof Identity Verification System
The future of combating deepfake threats involves a comprehensive approach that integrates multiple layers of security. Enhanced liveness detection must constantly evolve to stay ahead of increasingly sophisticated deepfakes. This can be achieved by incorporating machine learning and AI that can adapt to new forms of attacks.
Using a combination of biometric factors such as voice recognition, fingerprints, and iris scans adds an additional layer of verification, making it even more challenging for attackers to deceive the system. Behavioral biometrics, which analyse user behavior like typing patterns and navigation habits, can create unique user profiles that are hard to replicate.
Blockchain technology can also play a significant role by providing a decentralised, transparent, and immutable ledger to secure identity data, making it much harder for attackers to tamper with information.

Moreover, continuous authentication, which monitors and verifies user identity throughout the session, can replace one-time authentication methods, offering an added layer of security. Robust encryption is essential to ensure that all biometric data is encrypted in transit and at rest, preventing attackers from intercepting or manipulating data.
Finally, conducting regular security audits and staying updated with the latest cybersecurity research and trends helps patch vulnerabilities before they can be exploited.
The rise of deepfake technology poses a formidable challenge to traditional identity verification processes. By embracing a multi-layered strategy and leveraging a combination of advanced technologies, we can ensure the integrity of our identity verification systems.
