Upon initial observation, Daisy might easily be mistaken for the quintessential grandmother: she adores knitting, enjoys reminiscing about her family, owns a feline companion named Fluffy, struggles with modern technology, and has ample time for leisurely conversations. However, a closer look reveals her to be a technological marvel, equipped with a suite of ingenious strategies. This is because Daisy is an AI-powered conversational chatbot devised by the UK-based mobile telecommunications company O2, designed to counteract fraud by deceiving phone scammers into believing they are in conversation with a genuine human. Her recent introduction underscores the dual-edged role of AI in the realm of online scams. The Global Anti-Scam Alliance, an advocacy group, reports that consumers globally suffered losses exceeding $1 trillion due to online scams in the previous year. A record-high $12.5 billion in losses from online scams was reported to the FBI in 2023, as detailed in a March report. Conversely, the US federal government has lauded technology as "revolutionary" in assisting the Treasury Department in recouping $1 billion worth of check fraud in the fiscal year concluding on September 30. O2's objective with Daisy is to engage with fraudsters and consume as much of their time as possible through human-like, aimless chatter, thereby deterring them from interacting with actual individuals. The company has stated that her tactics have managed to keep "numerous fraudsters on calls for up to 40 minutes," as revealed in their announcement of Daisy's launch earlier this month. "Given that scammers operate full-time call centers specifically targeting British citizens, we urge everyone to stay alert," cautioned Murray Mackenzie, the director of fraud at Virgin Media O2. In the past year, Virgin Media O2, the broader telecommunications conglomerate, blocked over £250 million ($315 million) in suspected fraudulent transactions, claiming this equates to halting one scam every two minutes.

Daisy, utilizing a bespoke large language model, is capable of conducting autonomous conversations with scam callers in real-time. She does not intercept any calls; instead, she possesses multiple phone numbers that O2 has strategically disseminated online. Collaborated on with the London-based advertising agency VCCP, Daisy's voice was modeled after a staff member's grandmother. "While anyone can fall victim to a scam, criminal fraud rings often single out the elderly, so we played into the scammers' own prejudices by creating an AI granny inspired by a real family member of a VCCP employee," the agency explained in a separate statement. "Throughout countless hours of scam calls, she has shared rambling tales of her family, discussed her knitting passion at length, and provided false personal details, including fabricated bank information."

According to Virgin Media O2, Daisy was developed in response to research indicating that the British public's primary reason for not baiting scammers themselves is the reluctance to waste their own time. Daisy, on the other hand, has "all the time in the world." In fact, she is so time-rich that in a video introducing her character, one frustrated scammer can be heard exclaiming, "It's nearly been an hour!" over the phone. Another fraudster tells her, "I think your profession is bothering people." Her retort? "I'm just trying to have a little chat."

Daisy's creation represents a strategic move by O2 to leverage AI technology in the fight against fraud. By emulating the persona of an elderly individual, Daisy preys on the scammers' tendency to target the elderly, using this to her advantage. Her ability to engage in prolonged conversations serves a dual purpose: not only does it waste the scammers' time, but it also provides a valuable opportunity to gather intelligence on their tactics and methods.

The use of AI in combating scams is not without precedent. Various organizations have employed AI to detect and prevent fraudulent activities, from financial institutions using machine learning to identify suspicious transactions to E-commerce platform using AI to flag counterfeit goods. However, Daisy's approach is unique in that she directly confronts scammers, using their own tactics against them.

The success of Daisy's mission hinges on her ability to mimic human conversation convincingly. To achieve this, O2 and VCCP have invested in developing a sophisticated language model that can understand and respond to a wide range of topics and scenarios. This requires not only a vast database of language patterns but also the capacity to adapt and learn from each interaction, becoming increasingly adept at mimicking human speech.

Daisy's deployment also raises ethical considerations. While her primary goal is to protect individuals from fraud, there is a fine line between wasting a scammer's time and infringing on their rights. It is crucial that any use of AI in this context is carefully regulated to ensure it does not cross into unacceptable territory.

As AI technology continues to evolve, it is likely that we will see more innovative solutions to the problem of online scams. Daisy's story is just one example of how AI can be harnessed for good, protecting vulnerable individuals and disrupting the operations of criminal networks. However, it also serves as a reminder of the potential dangers of AI when used with malicious intent, highlighting the need for ongoing vigilance and responsible development in this field.

The story of Daisy, the AI granny, is a testament to the power of technology when used creatively and responsibly. Her mission to protect the public from fraud is a shining example of how AI can be a force for good in the digital age. As we continue to navigate the complexities of the online world, stories like Daisy's remind us of the importance of innovation, collaboration, and the relentless pursuit of solutions to the challenges we face.
