Embodiment 1

[0055] seefigure 1 , is a flow chart of the product write-off method provided in the first embodiment of the present invention, including steps:

[0056] Step S10, if a write-off request sent by any client is received, query the target product corresponding to the write-off request;

[0057] Wherein, the product identification is stored in the write-off request, and a product query table is pre-stored locally, and the product query table stores the corresponding relationship between different product identifications and corresponding target products;

[0058] Therefore, in this step, the product identification in the write-off request is matched with the product query table, and the target product is obtained according to the matching result. Optionally, the product identification can be in the form of text, code or image further, the write-off request is transmitted in the form of voice signal, text signal or touch signal.

[0059] Step S20, query the target smart contract c...

Embodiment 2

[0077] see figure 2 , is a flow chart of the product write-off method provided in the second embodiment of the present invention, including steps:

[0078] Step S11, if a write-off request sent by any client is received, query the target product corresponding to the write-off request;

[0079] In this embodiment, when the user's confirmation instruction for the target product is received, a product consumption code is sent to the user, and the product consumption code is used to generate the write-off request;

[0080] Further, please refer to the explanation of step S10 in the first embodiment, and the explanation of this step will not be repeated here.

[0081] Step S21, obtaining the storage ID of the target product, and querying the blockchain ledger according to the storage ID;

[0082] Among them, the information of each product is stored in the corresponding blockchain ledger. Blockchain technology is essentially a "database technology with unalterable historical rec...

Embodiment 3

[0113] see image 3 , is a schematic structural diagram of the product write-off device 100 provided in the third embodiment of the present invention, including: a product query module 10, a contract query module 11, an instruction sending module 12, a key detection module 13 and a contract modification module 14, wherein:

[0114] The product query module 10 is configured to, if a write-off request is received from any client, query the target product corresponding to the write-off request.

[0115] Wherein, the product query module 10 is further configured to: when receiving the user's check and confirmation instruction for the target product, send a product consumption code to the user, and the product consumption code is used to generate the write-off request.

[0116] The contract inquiry module 11 is configured to inquire about the target smart contract corresponding to the target product, and obtain the write-off identification in the target smart contract.

Abstract

The invention provides a product cancel-after-verification method and device, a mobile terminal and a storage medium, and the method comprises the steps: querying a target product corresponding to a cancel-after-verification request if the cancel-after-verification request transmitted by any client is received; querying a target intelligent contract corresponding to the target product, and obtaining a cancel-after-verification identifier in the target intelligent contract; if the cancel-after-verification identifier meets the cancel-after-verification condition, sending a key input instructionto the client; obtaining a cancel-after-verification key input by the client for the key input instruction, and performing permission detection on the cancel-after-verification key; and if the permission detection of the cancel-after-verification key is qualified, modifying the cancel-after-verification identifier in the target smart contract to complete the cancel-after-verification operation for the target product, and sending a cancel-after-verification result to the client. According to the method and device, the product cancel-after-verification state is stored in an intelligent contractmode, so that the cancel-after-verification state of each product can be effectively changed only once, malicious change of the product cancel-after-verification state is effectively prevented, and the credibility of product cancel-after-verification is improved.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a product write-off method, device, mobile terminal and storage medium. Background technique [0002] When a product is sold, in order to ensure that the product is not sold for the second time or resold, the user who bought the product for the first time can perform a write-off action. The product after the write-off cannot be sold again. If the user purchases the product and finds that the product cannot be sold Write-off means that the product is not normally sold for the first time. [0003] The existing product write-off process is stored in a centralized storage mode, and the validity of the data can be artificially controlled. The credibility of the product write-off result is not high, and malicious data tampering may occur. Products that have been sold and written off by users may be resold by modifying the data information, which in turn dama...
