Embodiment 1

[0042] This embodiment provides a two-dimensional code-based information presentation method, such as Figure 1-3 shown.

[0043] Preparation process:

[0044] After the tag information and other information that needs to be encrypted need to be integrated, preferably, part or all of it is encrypted with an asymmetric private key and encoded into the QR code; the matching information related to the tag information and the asymmetric encryption public key need to be stored in the Identifying equipment or identifying software.

[0045] The above-mentioned encrypted information is private information, that is, information that is specific to individuals or units during the information presentation process; the matching information related to the above-mentioned tags is public information during the information presentation process, that is, unified and standardized information, tag information and matching information One to one correspondence.

[0046] In order to ensure that...

Embodiment 2

[0062] An identification device for information presentation based on a two-dimensional code, comprising:

[0063] The identification unit is used to identify the two-dimensional code, obtain the marking information and encrypted information in the two-dimensional code, and the encrypted information of the two-dimensional code includes the first encrypted information and the second encrypted information; the second encrypted information does not pass the matching information Integrated path output;

[0064] a storage unit for storing matching information;

[0065] The integration unit is configured to search for matching information corresponding to the tag information, integrate encrypted information and matching information, and generate presentation information.

[0066] The presentation device further includes an output unit for outputting presentation information. The output presentation information is consistent with the format and format of the matching information; t...

Abstract

The invention relates to the field of data identification, in particular to a two-dimensional code technology. The invention provides an information presentation method based on a two-dimensional code, and the method comprises the steps: 1, identifying the two-dimensional code, and obtaining the marking information and encryption information in the two-dimensional code; Step 2, according to the two-dimensional code mark information, searching matching information corresponding to the mark information on identification equipment; and step 3, integrating the encrypted information with the matching information to generate presentation information. The technical problem of high two-dimensional code information acquisition cost in the prior art is solved, the data information is vividly restored, and data protection, offline display and cost reduction are realized.

Description

technical field [0001] The invention relates to the field of data identification, in particular to two-dimensional code technology. Background technique [0002] Two-dimensional codes are widely used, especially in high-tech industries, storage and transportation industries, wholesale and retail industries, and other industries that need to quickly label information on items. [0003] Prior Art 1: After the two-dimensional code on the text is recognized, the network address stored in the two-dimensional code is obtained, and relevant data is obtained according to the network address. After the relevant data is returned to the local, the information is presented directly, or the data obtained through the network request is combined with the local data to present the content. Finally, the purpose of restoring text information is achieved. The method of the prior art 1 is extremely dependent on the network, and this method requires the support of a terminal server and a datab...
