Persona Unveils Significant Advances In Detection Of Ai-Based Face Spoofs

Persona, a leading global identity platform, today announced significant advancements in its AI-based face spoof detection capabilities. These updates strengthen Persona’s ability to detect and prevent increasingly sophisticated generative AI fraud techniques.AI-based face spoofs – such as deepfakes, synthetic faces, and face morphs – have enabled fraudsters to scale attacks at an unprecedented pace. For businesses that rely on identity verification, this poses growing risks, from significant financial losses to reputational damage. Gartner predicts that by 2026, attacks using AI-generated deepfakes on face biometrics may lead up to 30% of enterprises to no longer consider identity verification and authentication solutions reliable in isolation. This underscores the need for multi-layered fraud prevention tools that can respond to emerging threats.“Given the 50x increase in deepfakes over the past few years, it’s evident that generative AI will continue to transform the fraud landscape,” said Rick Song, CEO of Persona. “Our fraud solutions are designed to adapt in real time to ensure our customers remain protected against even the most sophisticated attacks

Synthetic Data Has Its Limits — Why Human-Sourced Data Can Help Prevent Ai Model Collapse

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn MoreMy, how quickly the tables turn in the tech world. Just two years ago, AI was lauded as the “next transformational technology to rule them all.” Now, instead of reaching Skynet levels and taking over the world, AI is, ironically, degrading.Once the harbinger of a new era of intelligence, AI is now tripping over its own code, struggling to live up to the brilliance it promised. But why exactly? The simple fact is that we’re starving AI of the one thing that makes it truly smart: human-generated data.To feed these data-hungry models, researchers and organizations have increasingly turned to synthetic data. While this practice has long been a staple in AI development, we’re now crossing into dangerous territory by over-relying on it, causing a gradual degradation of AI models. And this isn’t just a minor concern about ChatGPT producing sub-par results — the consequences are far more dangerous.When AI models are trained on outputs generated by previous iterations, they tend to propagate errors and introduce noise, leading to a decline in output quality
