[0081] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0082] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0083] The data processing method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the application server 102 communicates with the evidence storage platform 104 and the data service provider 108 through the network, and the evidence storage platform 104 communicates with the trusted evidence storage alliance chain 106 through the network. The application server 102 obtains the data service request and the user-authorized data packet, and sends the data packet to the evidence storage platform 104; receives the encrypted evidence data packet returned by the evidence storage platform 104; the encrypted evidence data packet is obtained by the evidence storage platform 104 encrypting the data packet; signs the encrypted evidence data packet to obtain the signed encrypted evidence data packet, and sends the signed encrypted evidence data packet to the evidence storage platform 104; receives the evidence result returned by the evidence storage platform 104; the evidence result is that the evidence storage platform 104 sends the signed encrypted evidence data packet to the trusted evidence storage alliance chain 106, and the trusted evidence storage alliance chain 106 calls the smart contract to store the signed encrypted evidence data packet and then generates it; sends the evidence result and the data service request to the data service provider 108. The data service provider 108 receives the evidence storage result and data service request sent by the application server 102; sends the evidence storage result to the evidence storage platform 104; receives the evidence storage query result returned by the evidence storage platform 104; the evidence storage query result is that the evidence storage platform 104 sends the evidence storage result to the trusted evidence storage alliance chain 106, and the trusted evidence storage alliance chain 106 verifies the evidence storage result; according to the evidence storage query result, the data corresponding to the data service request is sent to the application server 102. Among them, the application server 102 can be implemented by an independent server or a server cluster composed of multiple servers. The data service provider 108 can be implemented by an independent server or a server cluster composed of multiple servers.

[0084] In one embodiment, Figure 2 As shown, a data processing method is provided, which is applied to Figure 1 The following steps are used as an example to illustrate the application server in the example:

[0085] Step 202, obtain the data service request and the data packet authorized by the user, and send the data packet to the evidence storage platform.

[0086] Among them, the user-authorized data package includes the user's authorized personal information, authorization time, data content (authorization credential field or file content), etc. The evidence storage platform is a participant in the trusted evidence storage alliance chain. The trusted evidence storage alliance chain is a blockchain that stores user authorization data. The trusted evidence storage alliance chain stores user authorization data in the blockchain by calling smart contracts, and issues certificates to alliance participants and users who apply to access alliance chain nodes. The content of the smart contract includes application server information with authentication conditions, user personal information (such as mobile phone information, identity information, name, etc.), business type, user authorization time, authorization results, specific business processes, and agreement content. The final evidence content meets the three properties of evidence (authenticity, legality, and relevance) and has proof effect. The business process is related to the business content. For example, the authorization evidence business process includes pop-up boxes, user three-factor verification, user click confirmation, and authorization success.

[0087] When an application server applies to become an authentication user, the trusted evidence alliance chain will issue a set of exclusive public keys and private keys to the application server so that the application server can sign the data. User data needs to be signed by the application server's private key before it can be stored on the chain. The application server that receives the public key and private key sent by the trusted evidence alliance chain meets the authentication conditions.

[0088] Specifically, the application client listens to and responds to the user's service triggering operation on the application client, generates a service authorization request based on the service triggering operation, and sends the service authorization request to the application client display interface. Then, it listens to and responds to the user's authorization confirmation operation on the application client and the user-authorized data packet, generates a data service request based on the authorization confirmation operation, and sends the data service request and the user-authorized data packet to the application server.

[0089] The application server receives the data service request sent by the application client and the data packet authorized by the user, and sends the data packet authorized by the user to the evidence storage platform.

[0090] Step 204, receiving the encrypted evidence data packet returned by the evidence storage platform.

[0091] Among them, the encrypted evidence data package is obtained by encrypting the data package on the evidence storage platform.

[0092] Specifically, when the evidence storage platform receives the user-authorized data packet sent by the application server, it encrypts the data packet to obtain an encrypted evidence storage data packet, and sends the encrypted evidence storage data packet to the application server.

[0093] Step 206, sign the encrypted evidence data package to obtain the signed encrypted evidence data package, and send the signed encrypted evidence data package to the evidence storage platform.

[0094] Specifically, the application server uses the exclusive private key allocated by the trusted evidence alliance chain to sign the encrypted evidence data package, obtains the signed encrypted evidence data package, and sends the signed encrypted evidence data package to the evidence platform.

[0095] Step 208, receiving the evidence storage result returned by the evidence storage platform.

[0096] Among them, the evidence storage result is that the evidence storage platform sends the signed encrypted evidence storage data package to the trusted evidence storage alliance chain. The trusted evidence storage alliance chain calls the smart contract to store the signed encrypted evidence data package and then generates it.

[0097] Specifically, after the evidence storage platform receives the signed encrypted evidence data packet sent by the application server, it transparently transmits (i.e. sends) the signed encrypted evidence data packet to the trusted evidence alliance chain. After the trusted evidence alliance link receives the signed encrypted evidence data packet, it executes the smart contract, stores the signed encrypted evidence data packet on the trusted evidence alliance chain, and returns the storage address of the signed encrypted evidence data packet to obtain the evidence result (i.e. the evidence hash value). The trusted evidence alliance chain sends the evidence result to the evidence storage platform. The evidence storage platform transparently transmits the evidence result to the application server. The application server receives the evidence result returned by the evidence storage platform.

[0098] Step 210, sending the evidence storage result and the data service request to the data service provider.

[0099] Specifically, the application server sends the evidence storage result and the data server request to the data service provider to obtain the data corresponding to the data service request.

[0100] In the above data processing method, the application server obtains the data service request and the data packet authorized by the user, and sends the data packet to the evidence storage platform; receives the encrypted evidence data packet returned by the evidence storage platform; the encrypted evidence data packet is obtained by the evidence storage platform encrypting the data packet; signs the encrypted evidence data packet to obtain the signed encrypted evidence data packet, and sends the signed encrypted evidence data packet to the evidence storage platform; receives the evidence result returned by the evidence storage platform; the evidence result is that the evidence storage platform sends the signed encrypted evidence data packet to the trusted evidence storage alliance chain, and the trusted evidence storage alliance chain calls the smart contract to store the signed encrypted evidence data packet and then generates it; sends the evidence result and the data service request to the data service provider. In the whole scheme, the participants of the trusted evidence storage alliance chain do not include the application server and the data service provider, which improves the isolation of user authorization data, and the multi-dimensional encryption processing of encrypting the user authorization data by the evidence storage platform and signing the encrypted user authorization data by the application server improves the security of user authorized data transmission, which is not easy to be illegally obtained, and the encrypted data is stored in the trusted evidence storage alliance chain. The data stored in the blockchain is not easy to be tampered with, which improves the security of user authorized data storage.

[0101] In an optional embodiment, if Figure 3 As shown, obtaining the data service request and the data packet authorized by the user and sending the data packet to the evidence storage platform includes:

[0102] Step 302, obtaining the data service request and the data packet authorized by the user, and normalizing the data packet to obtain a regular data packet.

[0103] Specifically, the application server receives the data service request sent by the application client and the data packet authorized by the user, and normalizes the data packet authorized by the user according to the data standardization rules in the smart contract to obtain a regular data packet.

[0104] Step 304, sending the regularized data packet to the evidence storage platform.

[0105] Specifically, the application server sends the regularized data packets to the evidence storage platform.

[0106] In this embodiment, the user-authorized data packets are standardized through the data standardization rules in the smart contract, which can improve the access efficiency of the user-authorized data.

[0107] In an optional embodiment, the data service request may also be generated after the application server receives the evidence storage result, and the application server packages the evidence storage result and the data service request and sends them to the data service provider.

[0108] In an optional embodiment, the encrypted evidence data packet is obtained by the evidence storage platform encrypting the data packet according to the regulatory agency key.

[0109] In this embodiment, the regulatory agency is a participant of the trusted evidence consortium chain, which supervises the execution of the smart contract and encrypts the user authorization data according to the regulatory agency key. Furthermore, the user authorization data is encrypted according to the regulatory agency public key, and the regulatory agency's public key and private key are distributed after authorization by the trusted evidence consortium chain.

[0110] In one embodiment, Figure 4 As shown, a data processing method is provided, which is applied to Figure 1 The data service provider in is used as an example to illustrate, including the following steps:

[0111] Step 402, receiving the evidence storage result and data service request sent by the application server.

[0112] Specifically, the data service provider receives the evidence storage result and the data service request sent by the application server.

[0113] Step 404, sending the evidence storage result to the evidence storage platform.

[0114] Specifically, the data service provider sends the evidence storage results to the evidence storage platform to verify the authenticity of the evidence storage results.

[0115] Step 406, receiving the evidence query result returned by the evidence storage platform.

[0116] Among them, the evidence query result is obtained by the evidence platform sending the evidence result to the trusted evidence alliance chain, and the trusted evidence alliance chain verifies the evidence result.

[0117] Specifically, after the evidence storage platform receives the evidence storage result sent by the data service provider, it sends the evidence storage result to the trusted evidence storage alliance chain. After the trusted evidence storage alliance link receives the evidence storage result sent by the evidence storage platform, it calls the query chain code to query whether the evidence storage result (with a hash value) exists. If the evidence storage result exists, it is generated as an authorized evidence storage query result and returned to the evidence storage platform. If the evidence storage result does not exist, it is generated as an unauthorized evidence storage query result and returned to the evidence storage platform.

[0118] After the evidence storage platform receives the evidence storage query results returned by the trusted evidence storage alliance chain, it will transmit the evidence storage query results to the data service provider.

[0119] The data service provider receives the evidence query results returned by the evidence storage platform.

[0120] Step 408: Send the data corresponding to the data service request to the application server based on the evidence query result.

[0121] Specifically, the data service provider obtains the data corresponding to the data service request based on the evidence query result, and sends the data corresponding to the data service request to the application server.

[0122] In the above data processing method, the data service provider verifies the evidence results sent by the application server based on the trusted evidence alliance chain to ensure the authenticity of the evidence results, and then obtains the data corresponding to the data service request of the application server based on the real evidence results, thereby improving the security of the data acquisition process.

[0123] In an optional embodiment, if Figure 5 As shown, according to the evidence query result, sending the data corresponding to the data service request to the application server includes:

[0124] Step 502: If the evidence query result is authorized, the data corresponding to the data service request is obtained.

[0125] Specifically, the data service provider identifies the result identifier in the evidence query result. If the result identifier is 1, the evidence query result is authorized, obtains the data corresponding to the data service request, and sends the data corresponding to the data service request to the application server.

[0126] If the result identifier is 0, the evidence query result is unauthorized, and an illegal acquisition prompt message is pushed to the application server.

[0127] Step 504: Send the data corresponding to the data service request to the application server.

[0128] Specifically, the data service provider sends the data corresponding to the data service request to the application server.

[0129] In this embodiment, the data service provider identifies the result identifier in the evidence query result and quickly determines the authenticity of the evidence result based on the result identifier, thereby improving the security and efficiency of user data transmission.

[0130] In an optional embodiment, the participants of the trusted evidence alliance chain also include a regulatory agency; the regulatory agency receives the certification request from the application server; verifies the identity information of the application server based on the certification request; when the identity information is verified, downloads the encrypted evidence data packet corresponding to the certification request from the trusted evidence alliance chain; and sends the encrypted evidence data packet to the application server.

[0131] Specifically, when a user has doubts about the authorization data, the certification operation is triggered in the application server, and the application server listens to and responds to the user's certification operation, generates a certification request, and sends the certification request to the regulatory agency. The certification request carries the application server identifier and the evidence storage result corresponding to the user authorization data to be certified.

[0132] The regulatory agency receives the certification request sent by the application server, parses the certification request, and obtains the application server identifier and the evidence storage result. The regulatory agency obtains the authorized list of the trusted evidence storage alliance stored locally, and queries whether the application server identifier exists in the authorized list. When the application server identifier exists in the authorized list and the identity information is verified, the encrypted evidence data packet corresponding to the certification request is downloaded from the trusted evidence storage alliance chain according to the evidence storage result; the encrypted evidence data packet is sent to the application server.

[0133] Furthermore, when the application server identifier exists in the authorization list and the identity information is verified, the encrypted evidence data packet corresponding to the evidence request is downloaded from the trusted evidence alliance chain based on the evidence result; the encrypted evidence data packet is decrypted according to the private key of the regulatory agency, and the decrypted evidence data packet is sent to the application server.

[0134] After receiving the decrypted evidence data packet, the application server uses its own public key to de-sign the evidence data packet and obtains the data packet authorized by the original user to view the authorization record.

[0135] In this embodiment, the certification process is supervised by the regulatory agency to ensure the validity of the application server identity, thereby improving the security of the certification process.

[0136] In an optional embodiment, the participants of the trusted evidence alliance chain also include third-party participants; the third-party participants supervise the execution process of the smart contract in the trusted evidence alliance chain.

[0137] In this embodiment, third-party participants, as unrelated parties, witness the execution process of the smart contract in the evidence storage alliance chain, increase the number of nodes in the alliance chain, and improve the security of user-authorized data storage.

[0139] (1) The application client sends a data service request and a user-authorized data packet to the application server.

[0140] (2) The application server receives the data service request sent by the application client and the data packet authorized by the user, normalizes the data packet, obtains a regular data packet, and sends the regular data packet to the evidence storage platform.

[0141] (3) When the evidence storage platform receives the user-authorized data packet sent by the application server, it encrypts the data packet to obtain an encrypted evidence storage data packet, and sends the encrypted evidence storage data packet to the application server.
