In a preemptive move to safeguard user privacy, Signal has implemented screen security measures to thwart Microsoft’s controversial Recall feature on Windows 11. The updated Signal client now defaults to blocking screen captures, employing a DRM-like approach akin to measures used by platforms like Netflix to protect copyrighted content.
Microsoft’s Recall, designed to provide users with a searchable “photographic memory” by continuously archiving screen activity, has sparked widespread privacy concerns. Signal developer Joshua Lund stresses that operating system providers, like Microsoft, must furnish developers with the necessary tools to prevent OS-level AI systems from accessing sensitive data within their applications.
While Microsoft offers default filtering of private browsing activity and allows users to exclude specific applications from Recall’s monitoring, Signal believes a more robust, default-on solution is crucial for ensuring fundamental user privacy.
Signal acknowledges that blocking screenshots may affect users who depend on accessibility features. However, the company maintains that protecting sensitive information from potentially intrusive AI functionalities is paramount. Users who require screenshot functionality can currently disable the new security feature under Signal Settings > Privacy > Screen Security.
