attached figure 1 It describes that most of the current anti-peeping devices use a layer of anti-peeping film on the surface of the screen. This type of anti-peeping film can only achieve the anti-peeping effect within a certain range of angles. effect, and cannot play a role in 100% information security protection
In addition, existing anti-peeping products are not combined with wearable devices through software control, and cannot achieve double protection

Embodiment Construction
[0018] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0019] See attached figure 2 , the core of the solution of the present invention is that when the user is in front of a digital display device such as a computer display screen, the pre-installed app of the system encrypts display elements such as gray scale or RGB color, and at this time, by wearing special glasses, glasses The smart chip inside decrypts the display image, and finally what the human eye sees is the real pattern of the screen, while other people can only see a blurred screen, and the information will not be leaked. And if encryption is not required, there is no need to start the encryption algorithm, and there is no need to wear a special security display unit.

The invention provides a confidential display method. The method comprises the steps of applying encryption transformation to an original image to form an encrypted image; displaying the encrypted image; applying decryption transformation to the encrypted image to obtain the original image; and displaying the original image through a confidential display unit worn in front of the eyes of a user. The invention furthermore provides a confidential display apparatus. The confidential display apparatus comprises an encryption unit used for applying the encryption transformation to the original image to form the encrypted image, a display screen unit used for displaying the encrypted image, a decryption unit used for applying decryption transformation to the encrypted image to obtain the original image, and the confidential display unit worn in front of the eyes of the user and used for displaying the original image. When the user is in front of a display device, an encryption algorithm encrypts a grayscale value or an RGB value; only when the user wears the confidential display unit such as glasses, an intelligent chip in the confidential display unit decrypts the encrypted image, so that human eyes can see a real pattern of a screen, and others only can see the fuzzy screen; and therefore, information is not leaked.
Description
technical field [0001] The invention relates to the field of information security. Background technique [0002] In work and life, there are more and more demands for information security protection in certain specific occasions. attached figure 1 It describes that most of the current anti-peeping devices use a layer of anti-peeping film on the surface of the screen. This type of anti-peeping film can only achieve the anti-peeping effect within a certain range of angles. As a result, it cannot play a role in 100% information security protection. In addition, existing anti-peeping products are not combined with wearable devices through software control, and cannot achieve double protection. Contents of the invention [0003] Aiming at the problems in the prior art, the object of the present invention is to provide a safe and reliable secret display method and a secret display device. [0004] In order to achieve the above object, the present invention provides a confide...
