As deepfake technology fuels a wave of digital fraud based on widely available Generative AI tools, Israeli startup MultiKol is stepping in with a pioneering solution: biometric voice recognition with deepfake protection. The company is developing tools to identify authentic human voices with unmatched precision, offering protection for banks, enterprises and government organizations.
“The threat is very real — With AI, anyone can fabricate a Zoom call, insert words into someone else’s mouth or trick a banker into transferring money using synthetic voice,” says co-founder Ofer Atzmon. “We are using good AI to fight the bad AI used by hackers on a daily basis. You may not know who’s on the other end of the line, and sometimes it’s your own recorded voice being used against you.”
MultiKol’s technology dives deep into the human voice, analyzing nearly 200 unique characteristics — from pitch and tone to subtle patterns that remain constant even if someone is hoarse or sick. This precision allows the system to spot the difference between a genuine voice and an AI-generated fake. Powered by advanced generative AI, it doesn’t just verify who is speaking — it also interprets the content of the conversation, providing a multi-layered defense against fraud.
Why does this matter?
Because deepfake scams are no longer rare or futuristic — they are happening every day. Imagine a banker getting a call from what sounds like a long-standing client, urgently asking to transfer funds. Or a family member answering a phone call with the familiar voice of a loved one, only to be manipulated into sharing sensitive information. Even politicians and CEOs have been targeted with fabricated audio urging followers to buy fake medicine or authorize fraudulent deals.

These scenarios aren’t hypotheticals
Cyber authorities in Israel alone have documented hundreds of such cases, with numbers rising daily. “Every day, new stories emerge about deepfake scams,” Atzmon said. “When we talk to investors and clients, they tell us we’ve arrived exactly on time.”
Ofer AtzmonBacked by the Israel Innovation Authority, private investors and a crowdfunding campaign, MultiKol is now moving from pilot programs into the global market. Its partnerships with banks, secure facility access control systems and defense organizations signal that biometric voice authentication is poised to become a critical tool in the worldwide fight against digital deception.
Looking ahead
The technology will only grow more vital as AI-generated fraud becomes more sophisticated. The company envisions its voice authentication being integrated into everyday interactions — from online banking and healthcare consultations to political campaigns and corporate boardrooms. In a future where it will be nearly impossible to tell real from fake with the naked ear, as they aim to be the safeguard that ensures trust, security and authenticity in the digital world.
