WHATSAPP has launched a beta feature called Scam Alert that employs an on-device machine learning model to identify suspicious messages from non-contacts. The model functions within the bounds of end-to-end encryption, analyzing incoming messages without sharing data with WhatsApp or Meta. Users receive warnings if a message is flagged, while senders remain unaware. Users can choose to block, report, or trust the conversation. Additionally, a transparency ledger tracks model releases.
WhatsApp also developed confidential analytics to gauge feature effectiveness while protecting user privacy. In related news, Signal introduced automatic key verification to enhance communication security.
