Signal Update Blocks Windows 11’s Recall Screenshot Tool

Encrypted messaging platform Signal has introduced a new privacy feature in its Windows 11 desktop app to counter Microsoft’s AI-powered Recall screenshot capture tool.

The update, detailed in a blog post titled “By Default, Signal Doesn’t Recall,” enables a “Screen Security” setting by default, preventing Recall from capturing screenshots of Signal chats.

Recall, launched by Microsoft in May 2024, is designed to take periodic screenshots of user activity to create a searchable history. While intended to aid users in retrieving past content, privacy advocates have raised concerns about its potential to inadvertently capture sensitive information.

Signal’s Screen Security feature employs Digital Rights Management (DRM) techniques, similar to those used by streaming services to prevent unauthorized copying. When enabled, any attempt to take a screenshot of the Signal desktop app results in a blank image, safeguarding the content from being recorded.

Users who wish to disable this feature can do so through the app’s settings, but Signal has implemented warnings to ensure users are aware of the potential privacy implications.

Signal’s commitment to user privacy is well-documented. The platform has consistently limited the data it collects, retaining only essential information such as account creation and last connection dates. This minimal data retention has been highlighted in instances where Signal was subpoenaed for user information but could provide only limited details due to its data policies.

In contrast, Microsoft’s Recall feature has faced criticism for its broad data collection approach. While users can configure Recall to exclude certain applications, the lack of default protections for privacy-focused apps like Signal has been a point of contention.

Signal’s latest update serves as a reminder of the importance of user-centric design and the need for transparency in data collection practices.
