The disclosure pertains to a biometric recognition method, the method comprising: receiving biometric data; performing a random transformation of low-bit data in received biometric data; randomly selecting one or more filtering algorithms to pre-process randomly transformed biometric data; and performing identity verification based on pre-processed biometric data.

Biometric identification method, server, and client

The invention provides an entrusted-authorization system and an entrusted-authorization method. The entrusted-authorization system comprises an accounting system, a switch module and an entrusted-authorization module, wherein the entrusted-authorization module stores entrusted-authorization parameters determined by the accounting system, the switch module is connected with the accounting system and the entrusted-authorization module for transmitting transaction request messages from the client terminal to the entrusted-authorization module for processing in case that the accounting system is unavailable, wherein the entrusted-authorization module verifies the transaction request messages according to the entrusted-authorization parameters; otherwise, the messages are sent to the accounting system for processing. The transaction request messages comprise financial account information, financial institution information, transaction-initiation institution information and transaction amount. With the entrusted-authorization system and entrusted-authorization method of the invention, a normal processing of transaction request can be ensured when the accounting system is unavailable.

Stand-in authorization system and stand-in authorization method

This application provides a data storage method which is applied to a data storage device and includes: acquiring a first user identification and first user data of a first user; determining, from at least two preset distributed hosts in different areas, a first identification distributed host corresponding to the first user identification and a first data distributed host corresponding to the first user data; sending the first user identification to the first identification distributed host, so that the first identification distributed host stores the first user identification, and generates and stores a first identity identification corresponding to the first user identification; receiving the first identity identification; and sending the first identity identification and the first user data to the first data distributed host, so that the first data distributed host stores them in an associated manner.

Data storage method, apparatus, device and storage medium using distributed hosts for user identifications

The invention provides a file transmitting method and system. The file transmitting method is used for a system comprising N network file systems, N file receiving and forwarding servers, N network access servers, N client servers and N backstage servers that are in a one-to-one correspondence with the network file systems, comprising: the backstage server sends a file transmitting request to the file receiving and forwarding server, the file transmitting request comprises information on the file sending party, the file destination party and the file to be transmitted; the file receiving and forwarding server verifies the legitimacy of the file transmitting request; if legitimate, a file is transmitted between the file sending party and the file destination party; otherwise, a response that prohibits the transmitting is generated and returned to the backstage server that initiated the request. With the invention, transmission of files can be realized.

End-to-end file transmission method and system thereof

A data transfer system and method are provided in the present invention. Wherein, the data transfer system and method comprises a source data obtaining service module and a target table updating service module, both of which are divided into a main part and an affiliated part, and wherein the affiliated part is a dynamic function library, which can package sub-processings such as source data obtaining, data transformation and data inserting/updating. Meanwhile, the data transfer system and method can support quasi real-time data transfer tasks and real-time data transfer tasks at the same time. The data transfer system and method support multi-computer disaster tolerance and extension, and the customization of the dynamic function library can facilitate the change in the requirements of data transfer.

System and method for data transfer

A system and a method for replicating data among heterogeneous databases are described. The system includes an initialization module for creating and initializing shared memory, a message queue and a semaphore; a processing module including a data reader, a data adapter and a data loader; a replication module for replicating the data in the shared memory to a target database according to the messages in the message queue; and a cleaning module for releasing the shared memory after the replication. The method includes creating and initializing the shared memory, the message queue and the semaphore; reading data from the source database, then converting the data into target data for a target database, and loading the target data in the shared memory; replicating the target data in the shared memory to the target database according to the messages in the message queue; and releasing the shared memory after the replication.
