Fig. 1B illustrates a second part of a timing chart of an evaluation expert information processing method according to an exemplary embodiment of the present application.
Fig. 1C illustrates an application diagram of a bid evaluation expert information processing method according to an exemplary embodiment of the present application.
As shown in fig. 1A, 1B, and 1C, the general flow of the bid evaluation expert information processing method provided by the present application includes:
prior to the evaluation of the transaction item, the transaction principal (e.g., the first party or their bidding agent) submits an expert extraction application to an expert extraction administrator in the expert extraction system 110. The expert extraction application comprises professional information, number information, time information and location information of the required bid evaluation experts.
After the expert extraction system 110 receives the expert application information submitted by the user, the expert extraction manager checks the expert application information, for example, whether the professional information of the bid evaluation expert matches the bid evaluation item or whether the number information matches the requirement.
After the verification is passed, the expert extraction system 110 individually encrypts the professional information, the person number information, the time information and the location information of the evaluation expert to obtain a corresponding first digital envelope, and uploads the encrypted professional information, the person number information, the time information and the location information to the block chain 120 through the chain service device. The evaluation expert information is independently encrypted, so that the independent use of the information in the subsequent operation process can be ensured.
The block chain 120 receives the encrypted professional information, the number of people information, the time information, and the location information, and shares them on the block chain. So that other nodes accessing blockchain 120 can obtain this information in a timely manner through the chain service device.
The expert repository 130 obtains the encrypted professional information, the information on the number of people, and the time information from the blockchain 120 through the chain service device. Meanwhile, the expert repository 130 sends a first decryption request for decrypting professional information, information on the number of people, and time information to the expert extraction system 110.
After receiving the first decryption request, the expert extraction system 110 decrypts the first digital envelope, obtains a first symmetric key corresponding to the professional information, the people number information, and the time information, and sends the first symmetric key to the expert repository 130.
The expert repository 130 decrypts the encrypted professional information, the person number information, and the time information using the corresponding first symmetric key, and extracts a group of expert lists according to the professional information, the person number information, and the time information. Meanwhile, the expert repository 130 individually encrypts the extracted set of expert list information to obtain a set of expert list ciphertexts and a corresponding second digital envelope, and uploads the individually encrypted set of expert lists to the block chain 120.
The blockchain node server 140 acquires the encrypted time information and location information from the blockchain 120 and transmits a second decryption request for decrypting the time information and the location information to the expert extraction system 110.
After receiving the second decryption request, the expert extraction system 110 decrypts the first digital envelope to obtain a second symmetric key corresponding to the time information and the location information, and sends the second symmetric key to the blockchain node server 140.
The blockchain node server 140 decrypts the encrypted time information and location information using the corresponding second symmetric key, obtaining the time information and the location information. In addition, the blockchain node server 140 obtains the encrypted set of expert list information from the block 120, and sends a third decryption request for decrypting the set of expert list information to the expert database 130.
After receiving the third decryption request, the expert repository 130 decrypts the corresponding second digital envelope to obtain a corresponding third symmetric key, and sends the third symmetric key to the blockchain node server 140. The blockchain node server 140 decrypts the encrypted set of expert list information using the corresponding third symmetric key to obtain a set of expert list information.
The blockchain node server 140 confirms a group of expert lists one by one according to the decrypted time information and the decrypted location information. The confirmed main content comprises whether the expert can participate in the bid evaluation at the corresponding time and place. The confirmation may be by telephone call confirmation.
According to the confirmation result, the blockchain node server 140 sets confirmation marks for the encrypted expert lists one by one, and uploads the encrypted expert lists with the confirmation marks to the blockchain 120 for sharing.
The expert database 130 obtains the respective confirmation marks of a set of expert lists from the blockchain 120. When the partial confirmation flag is "not passed," the expert repository 130 freezes the list of experts whose confirmation flag is "passed" in the expert repository for a period of time. The frozen expert list cannot be extracted for a period of time. And the expert list is unfrozen after the period of time. During the frozen period, the expert database 130 re-extracts the expert list according to the number of the expert lists marked as 'failed' by confirmation, and repeats the steps of encryption uploading of the expert database 130, decryption confirmation of the block chain node server 140 and the like. When all the confirmation marks of the expert list are "pass", the expert library 130 locks the expert list with the confirmation mark of "pass" to generate a final expert list, encrypts the final expert list, uploads the final expert list to the block chain 120 for sharing, and obtains a corresponding third digital envelope. The locked experts cannot be extracted within the corresponding time period.
When the evaluation is performed, the transaction center system 150 obtains the encrypted final expert list from the blockchain 120, and sends a fourth decryption request for decrypting the final expert list to the expert repository 130. The expert repository 130 decrypts the third digital envelope according to the fourth decryption request to obtain a fourth symmetric key, and returns the fourth symmetric key to the transaction center system 150.
The transaction center system 150 decrypts the encrypted final expert list by using the fourth symmetric key returned by the expert database 130, and confirms the expert who is present according to the decrypted final expert list.
As shown in fig. 1C, the expert extraction system 110, the expert database 130, the blockchain waypoint server 140, and the transaction center system 150 are all connected to the blockchain 120 through corresponding chain service devices for expert information sharing. Where the blockchain node server 140 may be a blockchain node deployed in an authoritative center, such as a government office. In the process of storing and transmitting the expert information, the expert database 130 is responsible for extracting the bid evaluation expert list, but the expert database 130 does not master the bid evaluation item information and the place information, so that the risk of disclosure does not exist. The blockchain node server 140 is responsible for confirming the bid evaluation expert, and although the blockchain node server 140 grasps the special list, the time information and the location information, it does not grasp the bid evaluation item information. Therefore, the leakage of the expert list can be avoided by separating the expert extraction link and the expert confirmation link and handing the expert extraction link and the expert confirmation link to different subjects for execution. In addition, the finally confirmed expert list is encrypted and shared on the block chain, and the trading center system obtains the expert list from the block chain during bid evaluation, so that the risk of leakage of the expert list is reduced.

According to a first exemplary embodiment of the present application, there is provided a bid evaluation expert information processing method based on a block chain, as shown in fig. 2, including:
in step S210, the expert extraction system individually encrypts the professional information, the number information, the time information, and the location information of the bid evaluation expert and uploads the encrypted professional information, the number information, the time information, and the location information to the block chain. Before the bid evaluation, a transaction subject user submits professional information, number information, time information and location information of bid evaluation experts required by a bid evaluation project through an expert extraction system. And the expert extraction system checks the information and then individually encrypts the information in a first encryption mode to generate a corresponding first digital envelope. Meanwhile, the encrypted professional information, the encrypted number information, the encrypted time information and the encrypted location information are uploaded to a block chain to be shared.
In step S220, the expert database obtains the encrypted professional information, the number of people information, and the time information from the blockchain and decrypts them. And the expert database acquires the encrypted professional information, the person number information and the time information and sends a first decryption request of the professional information, the person number information and the time information to the expert extraction system. And after receiving the first decryption request, the expert extraction system decrypts the corresponding first digital envelope to obtain a corresponding first symmetric key and sends the first symmetric key to the expert database. And the expert database decrypts the encrypted professional information, the person number information and the time information by using the corresponding first symmetric key.
In step S230, the expert database extracts a group of expert lists according to the decrypted professional information, the number information, and the time information, individually encrypts the expert lists by a second encryption, and uploads the encrypted expert lists to the block chain. And the expert database carries out independent second encryption on the extracted expert lists and obtains a second digital envelope corresponding to the encrypted expert lists.
In step S240, the blockchain link point server acquires the encrypted time information and location information from the blockchain and decrypts them.
And after acquiring the encrypted time information and the encrypted location information, the block link point server sends a second decryption request of the time information and the location information to the expert extraction system. And after receiving the second decryption request, the expert extraction system decrypts the corresponding first digital envelope to obtain a corresponding second symmetric key and sends the second symmetric key to the block link point server. And the block chain node server acquires a second symmetric key corresponding to the encrypted time information and the encrypted location information from the expert extraction system and decrypts the second symmetric key.
In step S250, the blockchain nexus server obtains the encrypted set of expert lists from the blockchain and decrypts the encrypted set of expert lists. And the blockchain node server acquires the encrypted group of expert lists and then sends a third decryption request of the expert lists to the expert database. And after receiving the third decryption request, the expert database decrypts the second digital envelope to obtain a corresponding third symmetric key and sends the third symmetric key to the block link point server. The blockchain node server decrypts using the third symmetric key and the encrypted set of expert lists.
In step S260, the block link point server confirms the group of expert lists one by one according to the decrypted time information and location information. In the process of list confirmation, the block chain link point server sets confirmation marks on a group of encrypted expert lists one by one according to a confirmation result and uploads the confirmation marks to the block chain. For example, confirming a list of experts that passed, setting a flag "pass" or a number "1"; the list of experts that have not been confirmed to pass sets a flag "fail" or a number "0".
And the expert database determines a final expert list according to the confirmation marks of the expert lists and encrypts and uploads the final expert list to the block chain. When the confirmation marks of the expert lists comprise 'failure', the expert database freezes the expert lists marked as 'pass' within a period of time; and in the period of time, the expert database re-extracts the expert list according to the quantity of the expert list marked as 'failure' by confirmation, encrypts and uploads the expert list to the block chain. And in the period of time, the block chain link point server confirms the newly extracted expert lists one by one, sets confirmation marks and uploads the confirmation marks to the block chain until the confirmation marks of the expert lists all pass. And the expert database locks a group of expert lists with the confirmation marks of 'pass' to form the final expert list, encrypts the expert list and uploads the encrypted expert list to the block chain.
And during the evaluation, the transaction center system acquires the encrypted final expert list from the block chain and acquires the corresponding symmetric key from the expert database to decrypt the encrypted final expert list. And according to the final expert list, the trading center system confirms the experts on site.
