Problems solved by technology

But there are still some problems, because the QR code is still a graphic, and the graphic is still easy to be copied in the digital age
Therefore, it will still lead to being stolen to use
Second, in view of the respective interests of channel disseminators and information publishers, the two parties still have difficulties in mutual trust, especially when the information itself contains greater value, such as cash cards issued by merchants, shopping coupons, etc.

Embodiment Construction

[0007] refer to figure 1 , the main system of the present invention includes an information server, a mobile device (possibly a mobile phone, PDA, MID, tablet computer, etc., mobile devices with wireless connections), and a two-dimensional code scanning device.

[0008] The information server sends the original two-dimensional code information package containing the authentication information / display information to the mobile device, wherein the authentication information part of the original two-dimensional code information can be encrypted to ensure the security of the information. There is no restriction on the way of encryption, it only depends on the requirements of the user's security level.

[0009] The information server provides four interfaces: (see figure 1 )

[0010] Device registration interface

[0011] Information sending interface

[0012] B-level authentication interface

[0013] A level authentication interface

[0014] Device registration interface: pr...

Abstract

The invention discloses a dynamic two-dimensional code system and a dynamic two-dimensional code method. When a mobile device displays a two-dimensional code passing authentication, since the two-dimensional code is probably duplicated (mobile phones can photograph and the like), a life cycle of the two-dimensional code is limited within a short time (for example: 10 minutes) so as to complete safer authentication. Limiting of the life cycle of the two-dimensional code signifies that different two-dimensional codes need to be generated each time, and the system and the method complete authentication through a corresponding mechanism, reduce existing operating mechanisms of an original two-dimensional code information device to the utmost extent and can be compatible with the original device as well as operated according to the new mechanism. Besides, when display information amount is overlarge, a mode of using a mobile device for directly accessing to hyperlinks is adopted to obtain more content for displaying.

Description

technical field [0001] The invention relates to the coding and decoding technology of two-dimensional codes and the computer data encryption technology. Background technique [0002] Due to the increasing use of two-dimensional codes, two-dimensional codes are characterized by larger capacity and stronger confidentiality than one-dimensional codes. But there are still certain problems, because the QR code is still a graphic, and the graphic is still easy to be copied in the digital age. Therefore, it will still lead to being stolen for use. Second, regarding the respective interests of the channel disseminator and the information publisher, the two sides still have difficulties in mutual trust, especially when the information itself contains a large value, such as cash cards issued by merchants, shopping coupons and the like. Then the information publisher hopes to keep the security status of the information in the whole process of the channel, and the verification is comp...
