Obtain a document, analyze the bid information from the bid manual, and broadcast the bid information to the consortium chain. Specifically, the bid information included in the bid manual includes the bid item name, bid opening timing, bid document (ciphertext) submission deadline time, review criteria, access conditions, deposit, and the like.

In this embodiment, when executing step S2, the blockchain network sends the bid manual to the second node so that the bidder can view the bid manual from the second node. The bidder prepares and submits the BIM bid documents according to the standards and requirements contained in the bid manual. Specifically, the bidder first creates a BIM model, selects and models Revit or other software tools according to the standards and requirements contained in the bid manual, and then the bidders perform a collision check. Design optimization is performed, and specifically, various mistakes are checked between the specialized pipeline of construction, structure, and equipment using the already constructed model and collision check software, and a collision check report is submitted. Derivation, finding irrational parts of the original list, reporting early to reduce controversy, pre-determining additional construction content, submitting design optimization advice, rational construction planning, etc. ..

Each key pair contains a public key and a private key for performing asymmetric encryption and decryption on the information of the corresponding node. The encryption process may be executed by each node or by the entity performing steps S1 to S4, and the encryption / decryption process may be executed by each node or execute steps S1 to S4. It may be executed by the subject.

The process of performing encryption and decryption using a key pair will be described by taking encryption and decryption of BIM bidding documents as an example at the second node. With reference to FIG. 4, bidder A first signs the BIM bid document using his private key A, and then bidder A uses the public key of the bidding platform B to sign the BIM. Encrypt bidding documents and signature information. When the bid platform B, that is, the subject of steps S1 to S4 in this embodiment receives the BIM bid document of the bidder A, the bidder A obtains the BIM bid document encrypted using the public key of this platform B. After decrypting and decrypting using the platform's private key and obtaining the decrypted decrypted text, bidder A decrypts the signature using his private key using the bidder A's public key. .. When the above-mentioned asymmetric encryption method is used, it is only necessary to transmit the encrypted information during the transmission of the information, and it is possible to effectively prevent information leakage without transmitting the key.

Specifically, the key pair corresponding to the first node is used for encrypting and decrypting the bid manual obtained from the first node, and the key pair corresponding to the second node is the second. The key pair corresponding to the third node is used to encrypt and decrypt the BIM bidding documents obtained from the third node, and the review result obtained from the third node is encrypted and decrypted. The key pair used and corresponding to the fourth node is used for encrypting and decrypting the successful bid result obtained from the fourth node.

In this embodiment, before executing step S6, the authenticity of the first node, the second node, the third node, and the fourth node is further checked, and the node is only when the node is true. Issue a key pair to. For example, if the first node is true, whether or not to issue a key pair to the first node, and conversely, not to issue a key pair to the first node and issue a key pair to the first node, is determined. It does not have to affect whether or not the key pair is issued to other nodes. By checking the authenticity of each node, it is possible to prevent fraudulent actors from misrepresenting participants such as bidders and bidders, and further improve the security of the bidding process.

After executing steps S5 and S6, the following steps are further executed.

Bid information, bid information, review results and / or successful bid results before broadcasting the bid information, bid information, review results and / or successful bid results to the consortium chain in steps such as steps S7, S1, S2, S3 and S4. On the other hand, encryption processing is performed. Specifically, the bid manual acquired from the first node is encrypted and decrypted using the key pair corresponding to the first node, and the key pair corresponding to the second node is used for the first. Encryption and encryption / decryption are performed on the BIM bid document acquired from the second node, and encryption / encryption / decryption is performed on the review result acquired from the third node using the key pair corresponding to the third node. Is performed, and encryption and encryption / decryption are performed on the successful bid result acquired from the fourth node using the key pair corresponding to the fourth node.

Step S8, record the result of the encryption process.

After executing steps S7 and S8, the following steps are further executed.

Step S9, when the traceability request is received, the target node to which the traceability request is directed is analyzed, and the target node is at least one of the first node, the second node, the third node, and the fourth node. be.

Step S10, the result of the corresponding encryption process is searched based on the key pair corresponding to the target node.

Step S11, based on the result of the searched encryption process, the appropriate bid information, bid information, review result and / or successful bid result are determined.

Step S12, the determined bid information, bid information, review result and / or successful bid result are returned.

The traceability request may be issued by a supervisory manager or a maintenance manager who executes the bid bid information processing method in this embodiment. The supervisor corresponds to the target that requires the traceability query, the traceability request points to one or more target nodes, and the target node is the first node, the second node, the third node and so on. It may be the fourth node. For example, if the supervisor needs to make a traceability query on the review result of the third node, the traceability request issued is directed to the third node, and when the step S10 is executed, the traceability request is sent to the third node. Based on the corresponding key pair, the result of the encryption process recorded when performing step S8 from the consortium chain is searched, then step S11 is executed, and the encryption is performed using the key pair used in the encryption at that time. Decryption, acquisition of the review result, execution of step S12, and return to the supervisory manager.

By executing steps S9 to S12, when facing traceability demand, information such as previously recorded bid information, bid information, review results and successful bid results can be obtained from the consortium chain, whereby the traceability query can be obtained. It is easy to carry out and pursue responsibility.
