Embodiment approach
[0076] 1) When presenting the decoding template by way of information projection:
[0077] Suppose the eyes see an image A and another image B projected to the fundus, then the image C actually obtained by the brain is a superimposed image of image B and image A. The overlay formula is as follows:
[0078] f(C)=f(B)+f(A) (1)
[0079] f(x) is the RGB component primary color value of pixel x in an image (the RGBA color space is used as an example in this embodiment, but it is not limited to this), and the value ranges from 0 to 1, where 0 corresponds to full black, and 1 A pure color corresponding to each color component. f(C)=f(B)+f(A) means that the RGB component primary color value of each pixel in image C is the sum of the RGB component primary color values of corresponding pixels in image B and image A.
[0080] In the embodiment of the present invention, the encoding process of the nth original pattern Sn using the above formula is as follows:
[0081] f(Cn)=f(Pn)+f(...

The invention discloses an information interactive method and an information interactive system. The method comprises the pattern restoring step of conducting aliasing on at least one decoding template to encoded patterns, corresponding to a plurality of original patterns, of the eye grounds of users and obtaining a restoration pattern corresponding to one of the original patterns, wherein the decoding template corresponds to a set of encoders used for encoding the original pattern of the original patterns. According to the information interactive method and the information interactive system, aliasing is carried out on the decoding templates corresponding to the specific users to the encoded patterns comprising information corresponding to the original patterns, so that the specific users directly see the information contained in the corresponding original patterns; in addition, the different specific users can directly see the information contained in the corresponding original patterns from the same encoded pattern through the corresponding decoding template, and resources are saved.
Description
technical field [0001] The invention relates to the field of information security, in particular to an information interaction method and an information interaction system. Background technique [0002] In order for a specific user to obtain specific information from an information carrier facing unspecified users, the specific information can be hidden in the image carrier in a visible or invisible form through the public key, and the specific user can pass the assigned private key The hidden information is extracted from the image carrier. In the existing technology, the user often needs to use a specific algorithm to analyze and process the acquired image carrier, extract the corresponding hidden information and then display it to the user through the display device, audio device and other display devices, but it is impossible for the user to directly and directly See hidden information in said image carrier. Therefore, it is necessary to find a safe and simple informat...
