Google DeepMind and GovTech scam detector
- Google DeepMind and Singapore's Government Technology Agency announced an on-device scam-detection tool at Singapore International Cyber Week 2026 on October 14, using a fine-tuned Gemma model that processes messages on smartphones to reach end-to-end encrypted conversations without transmitting data.
- A two-stage pipeline runs a lightweight classifier first, invoking Gemma only for confirmation to balance detection accuracy with battery efficiency.
- Training used Singapore-specific scenarios including impersonations of public institutions and banks, in a sovereign sandbox that excluded personally identifiable information.
On-device processing lets the tool analyze encrypted messages that server-side approaches cannot reach, without exposing private conversations. The collaboration addresses a crime category that accounts for the majority of Singapore's reported offenses and billions in financial losses.
