Embodiment Construction

[0145] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0146] First, the structure of the label of the present invention will be described.

[0147] figure 1 is a schematic diagram showing the structure of the label of the present invention.

[0148] Such as figure 1 As shown, the NFC tag according to one embodiment of the present invention includes a tag identification 10 , a tag data area 20 and a tag security area 30 .

[0149] Wherein, the label identification 10 is the identification identification of the label when it leaves the factory, which is unique and read-only after leaving the factory. The tag security area 20 is used to store the organization public key certificate and tag public key certificate information. The tag data area 30 is a data storage module for me...

Abstract

The invention relates to a label data refreshing method. The method comprises the steps that a user terminal reads NFC label data from an NFC label; the user terminal verifies whether the read institution public key certificate is legal or not by utilizing a pre-stored CA root certificate, and sends the label identifier and the ciphertext data to a background system after the verification is passed; the background system parses the ciphertext data by using a pre-stored label private key, encrypts and signs the parsed ciphertext data, generates updated NFC label data, and sends the updated NFClabel data to a user terminal; and the user terminal writes the updated NFC label data into the NFC label. According to the invention, the NFC label data can be dynamically updated, and payment can berealized based on the dynamically updated NFC label, so that the payment security can be ensured, and the payment efficiency and the user experience can be improved.

Description

technical field [0001] The invention relates to computer technology, in particular to a tag data refreshing method and system for an NFC tag, a tag data-based payment method and a system thereof. Background technique [0002] In the product design based on NFC tag payment, it is found that the use process and payment method can be optimized: [0003] (1) The industry generally believes that there is a risk of duplication or replacement in the static method. Although there is no static limit for NFC tag payment in the short term, it also has the same security risk as the static QR code in the long run. However, unlike dynamic two-dimensional codes that require additional equipment, NFC tags themselves have the ability to read and write, so the writable feature of NFC tags can be used to achieve the same ability as dynamic two-dimensional codes. [0004] (2) At present, the generation of NFC tags requires special equipment or App to operate, which is not conducive to user acc...
