Researchers at UC Riverside have developed a “universal” deepfake detector that achieved record-breaking accuracy rates of 95-99% across multiple types of AI-manipulated videos. Unlike existing tools that focus primarily on face-swap detection, this new system can identify completely synthetic videos, background manipulations, and even realistic video game footage that might be mistaken for real content.
What you should know: The detector represents a significant breakthrough in combating the growing threat of synthetic media across various applications.
- It monitors multiple background elements and facial features simultaneously, spotting subtle spatial and temporal inconsistencies that reveal AI manipulation.
- The system can detect inconsistent lighting on artificially inserted people, discrepancies in background details of AI-generated videos, and signs of manipulation in synthetic content without human faces.
- Several Google researchers participated in the development, though the company hasn’t indicated whether it will deploy this technology on platforms like YouTube.
Why this matters: The proliferation of cheap AI-powered deepfake tools has created an “out-of-control online spread” of synthetic videos used for non-consensual pornography, election misinformation, and financial scams targeting both consumers and executives.
- Many deepfakes depict women—including celebrities and schoolgirls—in non-consensual pornography.
- Scammers have begun using deepfakes during live video conferencing calls, creating new challenges for verification.
How it works: The universal detector takes a comprehensive approach that goes beyond traditional face-focused detection methods.
- “We assume that the entire video may be generated synthetically,” explains Rohit Kundu, the lead researcher at UC Riverside.
- The AI monitors spatial and temporal inconsistencies across all video elements rather than concentrating solely on facial features.
- It successfully flags realistic-looking scenes from video games like Grand Theft Auto V that aren’t necessarily AI-generated but could be mistaken for real footage.
The competitive advantage: This detector outperformed all other published methods for identifying face-manipulated deepfakes and achieved superior accuracy for completely synthetic videos.
- “Most existing methods handle AI-generated face videos—such as face-swaps, lip-syncing videos or face reenactments that animate a face from a single image,” notes Siwei Lyu at the University at Buffalo.
- “This method has a broader applicability range,” Lyu adds.
What’s next: The research team is already working on real-time detection capabilities for live video calls.
- “How do you know that the person on the other side is authentic, or is it a deepfake generated video, and can this be determined even as the video travels over a network?” asks Amit Roy-Chowdhury at UC Riverside.
- The researchers presented their findings at the 2025 IEEE Conference on Computer Vision and Pattern Recognition in Nashville on June 15.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
