Abstract: This application discloses a network communication method applied to a network communication system including a first network device in a first private network, a second network device in a second private network and a gateway device coupling the first private network to the second private network. The first network device receives a first data packet transmitted from a terminal to a target blockchain node, and acquires an actual network address of the target blockchain node; and generates a second data packet according to the first data packet and the actual network address, and transmits the second data packet to a virtual network address of the second network device in the second private network, so that the operation overheads generated when the gateway device generates virtual network addresses for blockchain nodes can be reduced, thereby saving a storage space of the gateway device.

Abstract: The present disclosure discloses a credit messaging system, a credit data storage method, a device, and a medium, and belongs to the field of network technologies. A server generates a unified user identifier based on user information of a user, generates, based on behavioral data of the user, credit data of the user through calculation by using a unified algorithm, and then, stores the credit data of the user and a corresponding user identifier into a block chain by using a target policy. In a block chain system, a unified user identifier is obtained for a same user, so that organizations in the block chain system may query credit data of the user according to the unified user identifier, thereby implementing high-quality data circulation and transactions while improving accuracy and comprehensiveness of queries for the credit data.

Abstract: A method for sharing a cross-platform account resource is described. An authentication request carrying a user name, a password, and an ID of an APP resource server is transmitted to an account management server, based on a register account on the account management server; an authentication ticket corresponding to the APP resource server is received from the account managements server, and the authentication ticket is stored, in which the authentication ticket carries a user ID, an authorization key and a refresh key; a resource request is transmitted to the APP resource server, based on the user ID and the authorization key in the authentication ticket; an APP resource is received from the APP resource server, after the APP resource server requests the account management server to verify the authentication ticket by using the user ID and the authorization key.

Abstract: The present disclosure provides a media data processing method. The method includes obtaining, after determining that a user client performs a service operation with a first service client, first video data from the user client and second video data from the first service client; and synthesizing the first video data with the second video data to generate service operation video data. The method also includes transmitting the service operation video data to the user client and the first service client; obtaining a processing result of the service operation from the first service client; storing the service operation video data and generating storage information; receiving an access request that is transmitted by a second service client and that carries the storage information; and obtaining the service operation video data according to the storage information and returning the service operation video data to the second service client.

Abstract: This application discloses a data processing method, system, and apparatus, a storage medium, and a device, and belongs to the field of database technologies. The method includes receiving, a trigger request; triggering, according to the trigger request, the first cloud encryptor to store a root key seed, an operating policy, a data key seed, and a data key identifier, and triggering the database proxy to store an encryption data dictionary, the operating policy indicating an operation policy of the first cloud encryptor. The method further includes receiving a data processing request from the client; sending first data that the data processing request requests to process and the data key identifier in the encryption data dictionary to the first cloud encryptor. The method further includes implementing the operating policy, processing the first data, and responding to the data processing request by using the second data.
