As shown in fig. 2, in this embodiment, an RFID-based information circulation method based on the system shown in fig. 1 includes:
s21, acquiring a first information content sent by a first sender terminal and generating a first transaction for a transaction subunit to send the first transaction to the blockchain system; the first information content comprises a first user ID of a first sender terminal, a second user ID of a first receiver terminal and information flow characteristic information of an object;

The method of circulation of this information is not affected. The information content can be obtained by scanning the configured two-dimensional code through a camera, or can be obtained by configuring a manual input interface and sending the manual input interface after manual input by a user.

and if the verification is passed, acquiring the information flow characteristic information of the object.
Specifically, when the receiving terminal needs to acquire detailed information, the Hash (tx 1) and the signature information m1 are acquired through the RFID electronic tag subunit and are sent to the association subunit, meanwhile, the transaction processing subunit is called to inquire the transaction stored on the block chain through the Hash (tx 1), the transaction contains the user ID1 of the sender terminal, the public key information of the first party is inquired according to the ID1, the signature information m1 acquired from the RFID electronic tag subunit is verified through the public key, and if the verification is successful, the transaction is proved to be true and credible.
In more preferred embodiments, after the transaction information is acquired, information in the transaction information, such as information flow characteristic information, may be sent to the human-computer interaction subunit, so that the human-computer interaction subunit decodes the information and displays the decoded information on a human-computer interaction interface for a user to view.
In a more preferred embodiment, the first transaction further comprises a first geographical location of the first sender terminal, the method further comprising:
sending a location information request to a GPS subunit to obtain a first geographical location of a first sender terminal;
in a more preferred embodiment, the first transaction further comprises a physical picture, the method further comprising:
and sending the picture request information to the camera subunit to acquire a real object picture of the object so that the final object receiving user can compare the real object picture with the real object picture.
After the first signature information is verified to pass, the circulation method further comprises the following steps:
acquiring a current first transaction hash and first signature information from the electronic tag subunit, receiving second information content sent by a first receiver terminal, and generating a second transaction from the first transaction hash, the first signature information and the second information content so that the transaction subunit sends the second transaction to the block chain system; wherein the second information content includes a third user ID of the second recipient terminal.
Receiving a second transaction hash value returned by the blockchain system;
sending a write-in request to the electronic tag subunit to enable the electronic tag subunit to write the second transaction hash value and the second signature information into the RFID electronic tag, and verifying the second signature information after the second receiver terminal acquires the second transaction hash value through the electronic tag subunit; and the second signature information is generated by the association subunit through the private key signature of the first receiver terminal on the second transaction content.
Specifically, the first receiving terminal in the method shown in fig. 2 may be the receiving terminal, or may be an intermediate relay terminal. Taking logistics information generated by a producer A-a buyer D as an example, an association subunit acquires information such as a user ID of A, a user ID of a carrier B (specified by A), production time of a product, delivery time, a manufacturer and the like from the producer A, packages the information to generate a transaction tx, calls a transaction processing subunit to send the transaction tx to a block chain platform, receives a transaction hash2 of the tx, signs the tx with a private key of A to generate signature information n, and writes the transaction hash2 and the signature information n into an electronic tag subunit.
After receiving a carried commodity, a user B reads a transaction hash2 and signature information n on an RFID electronic tag through an electronic tag subunit, and after verification is successful according to the preferred mode, the commodity is proved to be really sent by a producer A, at the moment, an association subunit acquires a transaction hash2 and signature information n stored in the current RFID electronic tag, and also a user ID3 (specified by the user B) and additional information (the additional information can be added by the user B according to the current scene) of a next-level receiver terminal, packs to generate a transaction TX, calls a transaction processing subunit to send the transaction to a block chain platform, and returns a transaction hash value hash 3; and the association subunit signs the transaction TX through a private key of the user B to generate signature information x, and finally, the electronic tag subunit writes the transaction hash value hash3 and the signature information x into the RFID, so that the task of the transit terminal is completed. The operation principle is consistent with that of the present embodiment if the next-stage receiver terminal is still not the final segment.
Further, the first signature information and the first transaction hash value stored in the RFID electronic tag are deleted. The transit terminal can erase the data in the user data area in the previous RFID label and rewrite new transaction data. And uploading the previous data to the blockchain for storage through a new transaction. Therefore, the storage in the RFID tag can be reused, and the problem of storage exhaustion caused by continuous data addition of the RFID tag is avoided.
Further, the previous-stage transaction is acquired from the block chain step by step according to the second transaction hash value until the first transaction traced back to the first sender terminal
Further, a plurality of transactions acquired step by step are sent to the man-machine interaction subunit so as to visually display the circulation line.
It should be noted that the data in the RFID tag is only transaction hash and signature information. The complete information is obtained by querying the blockchain for transactions, while the public key information is stored in the blockchain transactions via the user ID. Therefore, the use of extremely precious user data areas in the RFID electronic tags can be reduced, and more RFID tags with smaller storage capacity can be adapted. Meanwhile, the transaction in the blockchain does not need to store the signature of the user on the transaction. This also reduces the size of transactions in the blockchain, relieving the blockchain nodes of storage pressure.
The association subunit will include the user's GPS data in the transaction in the background, which will ensure that the actual geographic location of the item during the turn-around is recorded.
Through the account contract, the user need not write his own digital certificate into the transaction, but only his own user ID into the transaction. This may also effectively reduce the size of the transaction, relieving the blockchain node of storage pressure.
