Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a forensic traceability method based on RFID and blockchain according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a method for forensic tracing based on RFID and blockchain, including:
s11, generating a first tracing code, and respectively sending the first tracing code to the block chain system and the RFID chip for respective storage; the first source tracing code binds corresponding commodity information;
s12, receiving a registration request of the RFID terminal, configuring a first identity certificate uniquely corresponding to the first tracing code for the RFID terminal after verifying the validity of the RFID terminal, and sending the first identity certificate to a blockchain system for storage;
and S13, receiving the request information sent by the first terminal and making corresponding feedback. Wherein the first terminal comprises an RFID terminal and a non-RFID terminal.
Specifically, a unique traceability code is generated by the blockchain system during production of all commodities and is stored in the blockchain system and the RFID chip respectively. The first source tracing code binds identity information of the commodity, and the identity information comprises information of a commodity manufacturer, production time, production materials and the like. If the RFID terminal wants to acquire information through a scanning chip, a registration request needs to be sent to the blockchain system in the early stage of scanning, an identity certificate is issued to the RFID terminal after the blockchain system passes the verification, the identity certificate is in one-to-one correspondence with the unique traceability codes, and then the blockchain system makes different feedbacks according to request information sent by the user terminal.
It should be noted that the step of acquiring the identity certificate from the blockchain system by the RFID terminal only needs to initiate registration after the unique traceability code is generated, and the registration may be performed after the rejection request of the blockchain system is obtained after the request information is sent without any particular limitation. The SDK of the application system embedded in the RFID terminal firstly has an access certificate of a block chain, and an identity certificate corresponding to the tracing code is issued to the terminal after the access certificate is verified.
It should be further noted that the building of the blockchain system mentioned in the present invention may be building a multicenter blockchain system, allowing upstream and downstream supply chain manufacturers to independently deploy blockchain nodes, such as commodity production, processing, packaging, transportation, and sale; or upstream and downstream supply chain manufacturers adopt a mode of mixed deployment of a local server and a cloud server to perform various operations through respective trusted nodes.
In further embodiments, as shown in fig. 2 and 3, the type of the first terminal is an RFID terminal, and the making of the corresponding feedback information according to the type of the first terminal in step S13 includes:
receiving request information sent by an RFID terminal; the request information is generated after the RFID terminal scans the RFID chip; the request message includes a first traceable code:
and if the request information is a query request, returning the information queried by the RFID terminal according to the first tracing code.
If the request information is a write request, and the write request further includes a first identity certificate, verifying whether the first identity certificate is consistent with the identity certificate stored in the blockchain system:
and if so, receiving the write-in request, enabling the RFID terminal to scan the RFID chip and then acquire the commodity information, and encrypting and writing the acquired commodity information after signing into the block chain system.
It should be noted that, if the upper level is a manufacturer, the RFID terminal device corresponds to a processing manufacturer, and if the identity certificate is successfully verified, after the RFID terminal device acquires information of the commodity according to the first tracing code, during signing, the content of the signature may further include some information of the processing manufacturer, which may include information of the processing manufacturer, processing time, processing flow, and the like, and the information is encrypted and transmitted to the block chain after signing. The subsequent downstream manufacturers with the correct identity certificates read the information of the upstream manufacturers through analysis and verify, and write the information of the current stage into the downstream manufacturers for the downstream manufacturers to analyze, read and verify the information of all the upstream manufacturers; if the subsequent industrial chain is determined in the early stage, in order to further ensure the integrity of the industrial chain, the first-stage production manufacturer can also chain up complete supply chain manufacturer information so as to facilitate accurate verification of each stage.
By arranging the identity certificate in the RFID terminal equipment, only the RFID terminal with the unique traceability code can scan the RFID chip and analyze and read the plaintext content of the RFID chip and perform writing and inquiring operations of the block chain system, and for the RFID terminal without the correct identity certificate, the identity certificate can only acquire the content on the ciphertext inquiry block chain of the RFID chip, and the writing operation cannot be performed.
In further embodiments, the types of the first terminal include: the mobile client terminal or the computer terminal makes corresponding feedback information according to the type of the first terminal, and the feedback information comprises the following steps:
receiving request information sent by a mobile client terminal or a computer terminal; the request information is generated by scanning the RFID chip by the mobile client terminal or the computer terminal; the request message includes a first traceable code:
and if the request information is a query request, returning the information queried by the mobile client terminal or the computer terminal according to the first tracing code.
And if the request information is a write request, rejecting the write request.
Specifically, if a user uses a non-RFID mobile device such as a personal mobile phone and a computer, an application program loaded with a blockchain terminal needs to be installed for query, the application program does not have a certificate issued by a blockchain system, only encrypted traceability codes in an RFID chip can be read, and only a query interface of the blockchain system can be called through the encrypted traceability codes to query traceability information, but information entry cannot be performed; if the terminal consumer is confirmed by the information, the final sale information can be acquired through the RFID terminal equipment of the terminal salesman, the complete life cycle tracking of the commodities on the block chain is completed, and the secondary sale of the commodities is avoided.
And mobile equipment such as RFID terminal equipment with an RFID function can initiate query to the block chain system to obtain circulation information of commodities so as to confirm.
In more embodiments, the RFID terminal is further configured with a first identifier, where the first identifier corresponds to a request operation permission of the FRID, and corresponding write permission can be performed only when the production, logistics, sales, and the like have a clear identifier.
Specifically, for example, when the RFID terminal X of the processing manufacturer sends a registration request, the registration request further needs to indicate links of the processing manufacturer in all processes of production, processing, packaging, transportation, sale, and the like, where the links are "processing", and then the blockchain system further configures the first identifier X corresponding to "processing" for the RFID terminal X, so that the executed operation authority only has information content corresponding to "processing", such as writing into a processing flow, a processing line, and the like. If the RFID terminal Y of the carrier is a carrier, the first identifier Y corresponding to 'transport' is configured for the RFID terminal Y of the carrier, and the executed operation authority only has the information content corresponding to 'transport', such as the name written in the logistics provider, the transport time, the transit terminal of the transport and the like. It can be noted that the right content corresponding to the request operation can be defined well in advance to ensure the fluency of the whole process.
FIG. 4 is a flow diagram of another preferred embodiment of the method of FIG. 1. As shown in fig. 4, in this embodiment, if the write request information further includes the first identifier, the receiving the request information of the RFID terminal and making corresponding feedback information in step S13 includes:
s13', judging whether the RFID terminal has the authority of executing the corresponding request according to the first identifier;
and if so, providing feedback information to the RFID terminal, namely executing a corresponding request by the blockchain system and returning an execution result.
Specifically, after the identity authentication of the RFID terminal is completed, it is determined that the terminal can read chip content and there is a possibility that writing can be performed next, but if it is determined whether information collected by the terminal can be written into the block chain system, it is also necessary to obtain a first identifier in the write request information, and verify whether the written content is within the operation authority range of the terminal according to the first identifier, and if so, perform the write operation into the block chain system.
In more preferred embodiments, several modules are further configured in the RFID terminal device for acquiring the information related to the commodity when acquiring the information. More, the positioning module is used for acquiring the geographic position of the current operation; the sensing module can comprise a temperature sensor, a humidity sensor and the like and is used for providing environmental information such as temperature, moderate degree and the like and a clock module, wherein the environmental information is the current operation temperature; a clock module may also be included to provide the time of the current operation, etc.
