How to stop 99.5% of selfie video tampering with AI

Verifying identities with selfie videos is a powerful tool in the Know Your Customer (KYC) toolbox. However, this IDV method is vulnerable to fraudsters who use pre-recorded or counterfeit videos to fool the verification process. Fortunately, AI is here to help.

Selfie videos used to be a foolproof way of ensuring that your clients are who they say they are, for example when opening a new bank account. Clients are prompted to record a short video of their face while following a set of instructions such as looking from left to right. The videos are then used to verify the person behind the device.

However, with every leap forward in verification techniques comes a corresponding advance in fraud. By using fake videos, fraudsters can get around this step and gain access to your clients’ accounts. This poses a significant threat to businesses that rely on online identity verification for security, compliance, and client trust. It exposes them to potentially significant financial losses and reputational damage.

To address this challenge, Fourthline has built a proprietary system to detect selfie video tampering to enable financial service providers to ensure the integrity of their identity verification processes and stay ahead of fraudsters.

Understanding selfie video tampering

Selfie video tampering is where an individual submits a video for identity verification that does not meet the real-time requirements of the verification process. There are two main types of selfie video tampering:


Pre-recorded videos

Fraudsters use previously generated photographic or video material to falsify an identity verification in real time. They use various media from paper to TV, monitors, smartphones, and tablets to impersonate a client and gain unauthorized access to their funds.

Counterfeit videos

Fraudsters use advanced facial morphing and deepfake technologies to alter the facial features or voice in a video. This can be achieved by overlaying another person's facial features onto their own or by digitally altering video materials to mimic a real-time recording.
