Messaging app Signal will block Windows Recall from taking chat screenshots

Signal has introduced a "Screen Security" feature in its desktop application to prevent external programs, including Windows 11, from capturing screenshots of its interface. This feature is enabled by default and is a response to Microsoft's Recall feature, which captures app window screenshots for AI processing. Signal is concerned about the privacy risks posed by Recall's design, despite Microsoft's assurances of improved privacy controls. The developers have used Windows' Digital Rights Management technology to protect against unauthorized screenshots due to the lack of official APIs from Windows 11. Signal's leadership has criticized the need for such workarounds and has called on Microsoft to provide better tools for developers to safeguard user privacy.

Signal blasts Microsoft over Recall privacy failings, as secure messaging app is forced to fudge a way of blocking the controversial Windows 11 feature

Signal has introduced a new feature in its Windows 11 application that blocks Microsoft's Recall functionality to enhance user privacy. This 'screen security' setting is activated by default for Windows 11 users and is part of Signal's efforts to protect shared content on its platform. Recall captures screenshots of user activity on Copilot+ PCs, which raised privacy concerns. While Microsoft has improved Recall, issues with its interaction with privacy-focused applications like Signal remain. The feature is specifically applicable to users with Copilot+ PCs equipped with a Neural Processing Unit (NPU). Users can disable the screen security setting through Signal Settings > Privacy > Screen security, with a warning about the privacy implications of doing so.

Signal Will Black Out Windows Recall Screenshots to Preserve Privacy

Signal has introduced a "screen security" feature for its Windows 11 application to counter Microsoft's Windows Recall, an AI feature that captures screenshots of user activities. This new feature ensures that any attempts by Recall to take screenshots will result in a black screen. Signal's blog post notes that while the feature enhances privacy, it may cause compatibility issues with some accessibility tools, and users can disable it if necessary. The feature only protects the local machine and does not prevent other conversation participants from taking screenshots. Signal criticized Recall for lacking built-in privacy controls for app developers and emphasized the need for operating system developers to prioritize user privacy. The screen security feature is being rolled out and is enabled by default for Windows 11 users.

Signal says no to Windows 11’s Recall screenshots

Signal has updated its Windows app to enhance user privacy by preventing Microsoft’s Recall feature from capturing screenshots of secure conversations. The new version activates screen security by default, using a digital rights management (DRM) approach similar to that of streaming services. Users can disable this feature in the app’s settings, but concerns have been raised about its impact on accessibility features like screen readers. Developer Joshua Lund has highlighted the need for app developers to access tools that protect sensitive information from OS-level AI systems. Microsoft’s Recall feature, designed to enhance productivity, currently lacks an API to exclude sensitive content from its archives, posing privacy risks. While Microsoft has measures to filter activities from private browser windows, users must have technical knowledge to adjust settings for specific applications. Signal continues to adapt to digital privacy challenges while advocating for better support from operating system developers.

Signal will block Microsoft Recall from snooping on your texts

Encrypted messaging platform Signal is enhancing its Windows application with a feature called Screen Security, which prevents screenshots of messages while the app is in use. The application is flagged as protected by Digital Rights Management (DRM), ensuring that DRM content cannot be recorded in screenshots on Windows devices. Screen Security is activated by default but can be disabled by users if needed. Signal hopes that AI developers will consider the implications of their innovations more thoughtfully. The Recall feature in Windows 11, which allows users to record everything displayed on their screens, has faced privacy and security concerns, and skepticism remains about its readiness for widespread adoption.
