Problems solved by technology

However, the solution needs to add additional hardware, the cost is high, and it cannot prevent others from observing the content of the screen from the back of the screen
On the other hand, when the user needs to display the content on the screen to others through the screen, only the people directly in front of the screen can see the content on the screen, which is not easy to use

Embodiment approach

[0073] Mode 1, the extraction of the face image parameters related to the face image is the facial feature information of each face included in the image; the preset for judging whether the display unit of the computer performs an information protection action The standard information is the pre-stored facial feature information of the face with the computer use authority; the processing of the face image parameters and the preset standard information is to judge the facial features of each face included in the image. Whether the facial feature information matches the pre-stored facial feature information of faces with the computer use authority, when one of the facial feature information of each face included in the image matches the pre-stored face feature information with the When the facial feature information of the person's face with the computer usage authority does not match, the result information that the display unit of the computer needs to perform an information pr...

[0105] In the following, the image acquisition device is a camera, the display unit is a display, the camera is arranged on the display, and the computer is a notebook computer as an example for illustration.

[0106] Such as figure 1 As shown, the notebook computer of the first embodiment of the present invention includes:

[0107] A camera, set on the display, electrically connected to the host, used to obtain images including human face image information

[0108] Host, including:

[0109] Central processing unit (CPU), including:

[0110] a receiving unit, configured to receive the image including human face image information obtained through the camera connected to the host and arranged on the display unit;

[0111]The processing unit is used to process the image and extract face image parameters related to the face image. The parameters include: the number of faces included in the image, and the facial feature information of each face; call a Preset standard informati...

Abstract

The invention provides a method for preventing the peep on a computer and the computer with the method. The method comprises the steps of: acquiring an image which is at a specific distance before a display unit (namely a screen of a display) and comprises human face image information through image acquisition equipment (namely the prior camera); extracting human face image parameters related to a human face image in the image; processing the human face image parameters and preset standard information for judging whether a display screen of a computer performs information protection action; and performing the information protection action on the display screen of the computer according to a processing result to prompt a user of the current peep of the content on the screen of the display by others. But no extra hardwares such as a polarizing film, a birefringent film and the like need to be added, which reduces the cost.

Description

technical field [0001] The invention mainly relates to the field of computers, in particular to a method for preventing peeping on a computer and a computer with the method. Background technique [0002] With the rapid progress of semiconductor technology and electronic technology, computer technology has achieved amazing development. Notebook computers have become an indispensable electronic device for people. At the same time, current notebook computer users usually use the notebook computer to process private documents in public places (such as airports, railway stations, airplanes or trains, etc.). For example, watching power or browsing various web pages, or for security reasons, receiving private e-mails, etc., it is very necessary to prevent passengers next to or behind from observing the content on the screen. [0003] As a solution to the above problems, the prior art provides an anti-peeping screen for a display (eg, LCD), which has a polarizing film and a birefri...
