Block chain logistic source tracking anti-fake method based on NFC (Near Field Communication)

Abstract

The invention discloses a block chain logistic source tracking anti-fake method based on NFC (Near Field Communication). The method is based on a source tracking anti-fake system and comprises a publicly verifiable block chain background system, a block chain gateway system, a mobile intelligent read-write terminal, a cash databank and an NFC (IC) (Integrated Circuit) or internal NFC (IC) anti-fake label. The method comprises the following steps: generating an anti-fake label; initializing the anti-fake label; activating by a producer; adding information by a middleman; and verifying by a final user; after the anti-fake label is scanned at the read-write terminal each time, substituting a hidden password on an NFC chip and a corresponding visible password in a block chain by newly generated hidden passwords and visible passwords, and disabling the used hidden password and the visible password. By adopting the method, problems of trust dependence of users upon nodes in different product logistic procedures, trust dependence upon a third party, dependence upon techniques, trust dependence upon anti-fake labels and trust target deviation are solved, the introduction threshold is low, and the anti-fake security and reliability can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of block chain traceability, and in particular relates to an NFC-based block chain logistics traceability tracking anti-counterfeiting method. Background technique [0002] The existing traceability and tracking technologies mainly include the following types: (1) RFID wireless radio frequency technology, that is, to add a logo with a chip on the product packaging, and the information of the product in the business process can be recorded and read from the chip. Get complete information; (2) QR code, that is, the product is identified by the QR code, the QR code is associated with the relevant information of the product, and also records the relevant information: (3) Bar code, add the basic information of the product to the bar code Information, including the date of creation, production time, batch number and other information. Existing existing anti-counterfeiting technologies mainly include the following...

AI Technical Summary

Problems solved by technology

[0003] (1) Once it is physically copied, the anti-counterfeiting mark will become invalid immediately, and copying is only a matter of time and cost;

[0004] (2) No traceability, high link dependence, it is difficult to prevent self-stealing (need to trust multiple opaque links and individuals), for example, we need to trust retailers, shippers, express companies, etc. when we buy a Kun bag, and we often do not know the need Who are these links and people of trust;

[0005] (3) The existing anti-counterfeiting mark has no additional information or too little additional information;

[0006] (4) The technology is difficult and the cost is high. Only a small number of manufacturers can produce physical labels including metal wires and DNA anti-counterfeiting labels, and the production cost is high;

[0007] (5) The certification threshold is high and requires expert certification. Many anti-counterfeiting labels are difficult to fake, such as DNA anti-counterfeiting labels. Ordinary individuals cannot judge the authenticity. For example, in order to identify DNA anti-counterfeiting labels, professional certification personnel must be invited for certification
