In a recent episode of the Lights On Data Show with George Firican, Nametag’s CEO, Aaron Painter, delved into the evolution of deepfakes, and how they can be used for good... or ill. Read our episode summary below, then listen to the full episode to learn about:

  • Deepfake security methods: Watermarking content and AI detection methods.
  • Detection challenges: How defenders have locked themselves into an "AI arms race"
  • A better approach: Shifting from detection to prevention using advanced, novel technologies like mobile cryptography and biometrics.

The Origins and Proliferation of Deepfakes

Aaron begins by tracing the term "deepfake" back to its origins on Reddit and discussing its widespread presence on the internet today. He explains how deepfakes can be both beneficial and dangerous, highlighting the importance of recognizing their potential for misuse.

Current Defenses and How they Fall Short

One traditional method to combat deepfakes is watermarking content, which allows users to trace its provenance and verify its authenticity. Another common approach is detection, where AI is used to analyze content and determine its authenticity. However, Aaron points out a critical flaw in detection: it inevitably leads to an AI arms race, with both good and bad actors constantly improving their models. This constant flux in capabilities creates an inconsistent security landscape.

Shifting from Detection to Prevention

Aaron advocates for a shift from reactive strategies like watermarking and detection to proactive deepfake prevention. By focusing on prevention, organizations can avoid the endless cycle of one-upping adversaries in the AI arms race. He emphasizes that prevention doesn’t require reinventing the wheel but rather leveraging existing technologies such as mobile cryptography and biometrics.

These advancements are already prevalent in everyday activities, from unlocking phones to making purchases. By integrating these and other available technologies through solutions like Nametag, organizations can create a robust framework to validate identities without ripping and replacing existing systems.

The Business Case for Deepfake Prevention

As deepfake techniques become more sophisticated, detection will only become more expensive and challenging. Aaron argues that investing in prevention now is a more cost-effective and scalable solution for the growing threat. This proactive approach ensures organizations stay ahead of deepfakes, reducing the burden on helpdesks and lowering operational costs by automating routine tasks like account recovery.

A Better Approach to Preventing Deepfakes

To adopt this new focus on prevention, security teams need to evolve their approaches. Aaron suggests shifting from traditional penetration testing to more rigorous and assertive tactics that mirror real-world risks. By doing so, organizations can better prepare for the sophisticated threats posed by deepfakes and social engineering.

Taking these steps today not only protects your organization but also streamlines operations, reduces the load on helpdesks, and drives down costs. Investing in prevention now is essential for safeguarding your business in an increasingly complex threat landscape.
