Sensitivity labels from Microsoft Purview Information Protection offer highly effective controls to limit access to sensitive files and to prevent users from taking inappropriate actions such as printing a document, while still allowing unhindered collaboration. However, it’s still possible for users to take pictures of sensitive information on their screen or of a presentation being shared either online or in-person, and some forms of screen-shotting cannot be blocked with existing technology. This loophole presents an easy way to bypass protections that sensitivity labels enforce on a document.
In July we announced the public preview of dynamic watermarking, a new feature for sensitivity labels in Word, Excel, and PowerPoint, which will both deter users from leaking sensitive information and attribute leaks if they do occur. Today, we’re excited to announce an expansion of functionality: dynamic watermarking is now available in preview on Android and iOS, and admins are now able to add a date-time variable to the dynamic watermark display string.
With the Android and iOS release, you can now label files with dynamic watermarking-enabled labels and view, edit, and collaborate on these files regardless of which platform you’re using.
Adding a date-time variable to the dynamic watermark string enables admins to know precisely when leaked information was captured.
