Multiple-two-dimensional code tracing method based on digital identity and system thereof

Abstract

The invention provides a multiple-two-dimensional code tracing method based on a digital identity and a system thereof. By using the multiple-two-dimensional code tracing method based on the digital identity and the system thereof, multiple two-dimensional codes are used to carrying out discretion and information encryption on an access authority of product correlation information. Before and after final consumption, authorities for inputting, correcting and inquiring the product correlation information are designated, which is good for preventing tampered falsification, and guaranteeing authenticity and safety of traceability information; and a consumer can conveniently implement and operate.

Description

technical field [0001] The invention belongs to the technical field of information traceability, and specifically relates to a method and system for traceability of multiple two-dimensional codes based on digital identities. Background technique [0002] At present, the typical way of common anti-counterfeiting traceability system is to use barcode or QR code label as the entrance of products to the Internet of Things. Consumers scan the code with their mobile phones and link to the background database to query the static information entered before the product leaves the factory. , for example, the manufacturer's name, address, production standards, etc., and the logistics process information of the product, etc. [0003] The existing anti-counterfeiting traceability system lacks effective management of information in the product circulation process, and information management in the product sales link is also lacking. Although the anti-counterfeiting traceability label has ...

Problems solved by technology

[0003] The existing anti-counterfeit traceability system lacks effective management of information in the product circulation process, and the information management in the product sales link is also lacking. Although the anti-counterfeit traceability label has gone through all the links of the logistics and sales process with the product after the product leaves the factory, it is often collected. The data is incomplete or easily tampered, and the product quality traceability and anti-counterfeiting effects are not satisfactory in practical applications

[0004] Because many consumers have to enter the verification code through the mobile phone and send it to the background system, they usually do not take measures to check the authenticity, so that the product quality traceability anti-counterfeiting system established by these methods, in actual use, as the system runs more and more The longer the time, the more incompleteness of accumulated data, which makes it difficult for the traceability system service to meet the sustainable and healthy development of the commercialization process
