The rise of AI-powered voice cloning has prompted new security recommendations from law enforcement to protect against increasingly sophisticated scam attempts targeting families.
Key development: The FBI has issued official guidance recommending families establish secret passwords to verify identity during suspicious calls, particularly those claiming to be emergency situations involving loved ones.
- The recommendation comes through an official public service announcement (I-120324-PSA) released on Tuesday
- The FBI suggests creating unique, private phrases that family members can use to authenticate each other’s identity
- Voice verification has become necessary as criminals deploy AI technology to create convincing voice clones for fraudulent purposes
Technical context: AI voice synthesis technology has evolved to create highly convincing voice replications, typically using publicly available voice samples as source material.
- Voice cloning technology primarily targets individuals with public voice recordings, such as podcasts or interviews
- The technology has become increasingly accessible and simplified, making it easier for criminals to create realistic voice impersonations
- These AI tools can now mimic speech patterns, tone, and word choices with concerning accuracy
Broader security implications: The FBI’s warning extends beyond voice-based threats to encompass other AI-generated deceptive content.
- Criminals are utilizing AI to generate fake profile photos, identification documents, and chatbots
- These AI tools help automate fraud operations while eliminating traditional red flags like poor grammar
- The automation of deceptive content creation has made scams more sophisticated and harder to detect
Historical perspective: The concept of using secret words to combat AI voice cloning has recent origins but builds on ancient security practices.
- AI developer Asara Near first proposed the “proof of humanity” word concept on Twitter in March 2023
- The idea has gained traction within the AI research community as a simple, cost-free security measure
- The approach adapts the ancient practice of passwords for modern AI-driven security challenges
Preventive measures: The FBI has outlined several protective steps beyond secret passwords to guard against AI-enabled fraud.
- Individuals should limit public access to their voice recordings and images online
- Social media accounts should be set to private with restricted follower lists
- Family members should pay close attention to suspicious calls, noting unusual patterns in tone or word choice
Looking ahead: While AI technology continues to advance, this situation demonstrates how relatively simple security measures can provide effective protection against sophisticated threats, though ongoing vigilance and adaptation of security practices will be necessary as AI capabilities evolve.

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.
