Google DeepMind and Singapore Government collaborate to build fine-tuned AI model for scam detection
Google DeepMind partnered with Singapore's GovTech to launch an on-device scam detection model, fine-tuned from a lightweight Gemma model on local scam conversation data, that analyzes conversations on-device and warns users of manipulative tactics in real time. Scams account for more than half of police reports in Singapore and have caused over S$4 billion in losses since 2019, with social engineering scams making up as much as 80% of losses. The model uses a two-stage pipeline to preserve battery life, and training data was anonymized and contains no citizens' personal information.
