Google’s recent demonstration at its I/O conference of a new AI-driven call scam-detection feature has stirred a significant debate among privacy and security experts. This feature, which will be integrated into a future version of the Android OS, uses generative AI technology to scan voice calls in real-time for patterns associated with financial scams.
The primary concern raised by critics revolves around the implications of client-side scanning. This technology, while not new, has been controversial due to its potential misuse in broader surveillance and censorship efforts. Privacy advocates worry that once such scanning capabilities are embedded in devices, they could be exploited by governments or other entities to monitor more than just potential scams.
Experts like Meredith Whittaker, president of Signal, and Matthew Green, a cryptography expert at Johns Hopkins, have expressed their concerns vividly. Whittaker warns that this technology could easily be extended to monitor communications for a variety of other reasons, potentially leading to invasive surveillance. Green highlights the future risks of AI models running inference on texts and calls to detect and report various behaviors, which could lead to a form of censorship by default.
This is incredibly dangerous. It lays the path for centralized, device-level client side scanning.

European Response
In Europe, the reaction has been similarly wary. Lukasz Olejnik, a privacy and security researcher, acknowledges the potential benefits of anti-scam features but cautions against the broader implications of such technologies. He notes that while the detection might be performed on-device, enhancing privacy, the capability itself could be repurposed for more intrusive monitoring of personal communications.
Michael Veale, an associate professor in technology law at UCL, also highlights the risks of function-creep, where technologies initially developed for one purpose are expanded to others, often with less stringent oversight or public scrutiny.

Legislative Context
These developments come at a time when the European Union is considering controversial legislation that would require platforms to scan private messages for illegal content, a move that has been criticized by privacy advocates and even the bloc’s own Data Protection Supervisor. The proposed legislation aims to combat child sexual abuse material and grooming but is feared to infringe on privacy rights and lead to widespread surveillance.
As these technologies continue to develop, the challenge will be balancing the benefits of AI in combating fraud and scams against the potential for misuse and erosion of privacy. Engaging with a broad range of stakeholders, including policymakers, privacy advocates, and the public, will be crucial in shaping how these technologies are governed and implemented.
