Technical Field
The invention relates to the technical field of computers, in particular to a computer anti-disclosure system with a sentinel function.
Background
With the development of information science and technology, various electronic products of networks and network terminals are inseparable from the daily life of people. Although there have been great changes in human-computer interaction modes, such as the input from the previous keyboard to the current touch screen, wearable devices supported by sensor technology and new display devices represented by google glass, most of the information display modes of the current electronic products are transmitted to users through screens, which easily causes the information of the users to be peeped and leaked, especially when the privacy is strong and the personal private information is to be processed.
Two methods of active peep prevention and passive peep prevention are mainly used for realizing the peep prevention of the computer screen. Passive peep-proof is to use a special screen film, and the screen content cannot be seen at a certain angle. The active peep-proof detects whether a person reaches the visual range, and the person actively hides the computer window or directly enters a screen protection mode so as to achieve the aim of peep-proof. Compared with the two methods, the active peep-proof safety is better obviously, and the method is suitable for occasions with higher confidentiality requirements. For this reason, some active peep-proof methods have been adopted.
Most active peep-proof methods are to make the screen enter the screen saver mode, but when entering the screen saver mode, the user cannot see the content on the screen, so how to make the user see the content on the screen while performing active peep-proof becomes a problem to be solved urgently.
