WhatsApp announced a new security feature aimed at helping users verify the identity of the people they communicate with, especially if they are not registered in the contact list.
The user needs to activate the feature manually via settings. Once activated, the application downloads a machine learning model that runs locally on the user’s device, which means that “Meta”, the parent company that owns “WhatsApp”, does not receive any copy of the content of the conversations, nor does it share it with any third party, according to the company’s assurances.
The fraud alert system was built on previous conversations reported by users as fraud attempts, and was used to train the AI model to recognize suspicious messages.
The feature is currently being released in a limited trial version to a group of early users, and WhatsApp plans to conduct extensive tests of the system and called on researchers to report any vulnerabilities, before it is circulated to all users at a later stage. (Russia Today)
