With the prevalence of remote work, it is possible that a significant amount of highly confidential or restricted data may be shared and discussed over virtual meeting applications. The most vulnerable point during a highly confidential (or casual, off-the-record) meeting is each individual's client, which could allow a user to record the screen or take a series of screenshots. Presently, solutions exist that either allow complete recording of the screen, including the meeting windows, or no recording at all. However, there is no solution that enables the complete functionality of other windows or applications while blocking the meeting content alone. To address the types of challenges that were described above, techniques are presented herein that support selectively blocking only the vulnerable sections of a screen in a non-intrusive way thus ensuring both user convenience and privacy protection.
