Security Threats

In everyday operations, users have access to and work on sensitive files. However, it is difficult for companies to prevent users taking photo/video against computer’s screen by using mobile phone when accessing sensitive information (e.g. personal information, CCTV footage and other sensitive data). Due to COVID-19, more and more people work from home. Companies have to allow users to download data to notebook and access the data at home or allow them to connect to company’s network through VPN. It increases the difficulty of preventing data leak through screen.

Online meeting is another security challenge. When people need to show something to meeting participants (e.g. contracts, designs and even training materials) during online meeting, how to protect the information shown to participants? Although we cannot prevent people to take photo/video against computer’s screen, at least we should be able to trace the source of data leakage.
